At present, for high-pollution enterprises, some pollutants (such as COD, ammonia nitrogen, total phosphorus, etc.) in the production process will settle to the ground outside the factory building due to the poor airtightness of the factory buildings, or some pollutants will be carried with them during operation and transportation. At this time, if the rainwater falls on the ground outside the factory building, the pollutants will mix with the rainwater and be directly discharged into the river along with the rainwater, which will cause serious pollution; After being collected and treated up to the standard, it is discharged into the river.

At present, the enterprise's treatment method for rainwater is as follows: a sump with water inlet pipe and drainage pipe is preset, and the rainwater is discharged into the sump collectively, and then the operator puts a treatment agent into the sump, and the treatment agent is used to treat the polluted Rainwater is treated, and the pollutant content in the rainwater is detected through prefabricated water quality testing equipment. Based on the test results of the water quality testing equipment (hereinafter collectively referred to as water quality data), when the rainwater reaches the standard, the operator opens the valve on the drain pipe to collect The rainwater in the pool is drained.

The problem of the overflow of the sump due to the untimely acquisition of the amount of rainwater and the untimely treatment of rainwater needs to be improved.

Contents of the invention

In order to improve the current technical problems of low efficiency and poor timeliness in the management and control of rainwater discharge existing in related technologies, the present application provides a rainwater discharge monitoring and control method, system, platform and storage medium.

In the first aspect, the present application provides a method for monitoring and controlling rainwater discharge, which adopts the following technical solution:

A rainwater discharge monitoring and control method, comprising:

Acquiring liquid level data every preset time period; wherein, the liquid level data is the preset rainwater liquid level in the sump;

Comparing each of the water quality data with the preset content value, based on the comparison result between the target water quality data and the preset content value, at the discharge time corresponding to the target water quality data, control the discharge of the preset pumping and drainage equipment Rainwater; wherein, the target water quality data refers to any water quality data, and the discharge time refers to the corresponding moment when the comparison result between the target water quality data and the preset content value is obtained.

By adopting the above technical scheme, the water volume in the sump is determined by regularly monitoring the liquid level data of the rainwater discharged into the sump. Only when the liquid level data exceeds the standard will the prefabricated water quality detection equipment be activated to check the current water in the sump. The pollutant content is monitored, and the detection frequency of the water quality testing equipment is determined by the liquid level in the sump. If the liquid level data in the sump is always higher than the first liquid level data, the water quality testing equipment will continue to detect until the liquid level The water level data is lower than the first liquid level data, and the water quality data obtained in the process determines the discharge of rainwater in the sump. The preset discharge device will discharge rainwater based on the comparison result, thus realizing the monitoring of the water in the sump. The automatic discharge of rainwater improves the timeliness of rainwater treatment in the sump and reduces the overflow of the sump due to untimely treatment.

Optionally, based on the comparison result of the target water quality data and the preset content value, controlling the preset pumping and drainage equipment to discharge rainwater at the discharge time corresponding to the target water quality data includes:

By default, the mixture of rainwater and pollutants in the sump is relatively static at this time, and the side wall area is obtained at this time. and the water quality data of the inner circle area, that is, the data of the side wall area and the data of the inner circle area. If the data of the side wall area and the data of the inner circle area meet the above requirements, it is determined that pollutants have accumulated on the inner wall of the sump, and the sump needs to be cleaned. Otherwise, the accuracy of water quality data will be affected.

Therefore, the above scheme calculates and displays the sediment volume, So that when the operator sees the warning message of the inner wall deposition, he can artificially judge whether it is necessary to clean the inner wall of the sump tank immediately according to the volume of the sediment, or only start cleaning when the volume of the sediment on the inner wall of the sump tank reaches the specified size, so as to alleviate The labor intensity of cleaning the sump.

Optionally, the water quality data is pollutant content data, and before displaying the inner wall deposition warning message with the sediment volume, it also includes:

Obtain the water quality data corresponding to the current moment, and determine the total discharge of pollutants and the total amount of pollutants within a specified time period based on the preset discharge amount of pollutants per unit time, wherein the specified time period The total discharge of pollutants = the working hours of the pumping and drainage equipment within the specified period of time * the discharge of pollutants per unit time, the total amount of pollutants within the specified period of time = the water quality data at the current moment + the pollution within the specified period of time total discharge;

The above time is the cleaning time. The operator checks the inner wall deposition warning Information, you can see the cleaning time given by the system, and provide convenience for the cleaning personnel to clean the sump by predicting the approximate time when the inner wall of the sump needs to be cleaned.

detailed description

The present application will be described in further detail below in conjunction with accompanying drawings 1-4.

The embodiment of the present application discloses a method for monitoring and controlling rainwater discharge. Referring to Figure 1, the rainwater discharge monitoring and control method is used to control the discharge of rainwater, especially the rainwater around high-pollution enterprises, because the rainwater around high-pollution enterprises is easily mixed with the discharge of high-pollution enterprises in the production process Pollutants, the rainwater mixed with the above-mentioned rain and sewage will generally be collected in the pre-set sump of the enterprise. The sump is connected with a water inlet pipe, an inner drainage pipe and an outer drainage pipe. It is used to treat the rainwater that exceeds the standard, and then discharge it after the treatment reaches the standard. The sump is connected with the river in the external environment through the external drainage pipe; the rainwater discharge monitoring and control method is used when the liquid level in the sump is too high and needs to be discharged. Determine whether the pollutant content in the sump exceeds the standard. If it exceeds the standard, the rainwater in the sump will be discharged to the treatment pool, otherwise, it will be discharged to the river.

Specifically, the executive body of the above rainwater discharge monitoring and control method is the supervision platform, supplemented by water quality testing equipment, liquid level detectors and pumping and drainage equipment; the liquid level detector is used to detect the liquid level in the sump, and the liquid level detector can It is a float level gauge or a single level gauge. The water quality detection equipment is used to detect the pollutant content in the rainwater in the sump. The water quality detection equipment may specifically include a COD analyzer with its own pump, and may also include a PH meter for calculating the acidity and alkalinity of the rainwater in the sump. The pumping and drainage equipment is used for pumping and draining the rainwater in the sump, and the pumping and drainage equipment includes an outer drainage pump connected with the outer drainage pipe, and an inner drainage pump connected with the inner drainage pipe.

The above-mentioned water quality detection equipment, liquid level detection gauge and suction and drainage equipment are all connected to the supervision platform through communication. data, the liquid level data of the liquid level detector; optionally, a rain sensor for detecting whether it is raining can be installed on the outer wall of the sump. When the rain sensor detects rain, the monitoring platform starts the above water quality detection equipment, liquid level Detector, when the rain stops, the supervision platform can close the above-mentioned water quality detection equipment and liquid level detector.

The main operation process of the above rainwater discharge monitoring and control method will be described in detail below in conjunction with accompanying drawings 1 and 2, the contents are as follows:

Step 101, acquiring liquid level data every preset time period; wherein, the liquid level data is the preset rainwater liquid level in the sump;

In the implementation, the preset duration can be 5 minutes, and the liquid level detector detects the liquid level data in the sump in real time, but in order to reduce data redundancy, the monitoring platform only acquires a liquid level data every preset duration, and Store the liquid level data obtained above and the corresponding acquisition time in the preset liquid level storage table; in order to facilitate the operator to observe the liquid level trend, the monitoring platform can also draw a time-based graph based on the obtained liquid level data. The abscissa, the liquid level value is the liquid level change chart of the vertical coordinate, and the above liquid level change chart is displayed; the operator can access the management and control platform in the form of a website, and log in to the management and control platform in the form of an account password to view the above liquid level change icon information .

Step 102, if the liquid level data is higher than the preset first liquid level value, then based on the preset frequency, the water quality data of the rainwater in the sump is acquired, and the acquisition is stopped until the liquid level data is not higher than the preset liquid level value.

In the implementation, the water quality detection equipment is always in the state of detecting the water quality data of the rainwater in the sump in real time. In order to facilitate the operator to intuitively understand the water quality data in the sump, the monitoring platform can receive the water quality at preset intervals (such as 5 minutes) data, and store the received water quality data and its receiving time in the preset water quality storage table, and then draw and display based on the water quality data and receiving time in the water quality storage table, with the receiving time as the abscissa and the water quality data as the ordinate water quality change table.

In addition, the monitoring platform compares the liquid level data obtained every preset time period with the preset first liquid level value one by one in the order of acquisition time, and each comparison will generate a liquid level comparison result , the comparison results include the first comparison result and the second comparison result, wherein the specific content of the first comparison result is "the liquid level data is higher than the first liquid level value", and the specific content of the second comparison result is "The liquid level data is not higher than the preset first liquid level value". And the monitoring platform presets the initial content of the liquid level comparison result to NULL, and the monitoring platform will replace the previous liquid level with the specific content of the obtained liquid level comparison result every time a liquid level comparison result is obtained. The content of the comparison result, for example, the liquid level comparison result corresponding to the previous acquisition time is the first comparison result, and the liquid level comparison result at the current acquisition time is the second comparison result, then the monitoring platform will The specific content of the liquid level comparison result is replaced by the first comparison result with the second comparison result.

When the liquid level comparison result is the first comparison result, the monitoring platform will continue to retrieve water quality data at a preset frequency (such as every 5 minutes) according to the current time until the content of the comparison result is switched to the second comparison result. The result; the water quality data retrieved above is the water quality data detected by the water quality testing equipment from the current time. For example, at 8:00, the specific content of the comparison result is switched to the first comparison result, and at 8:00 :20 o'clock, the specific content of the comparison result is switched to the second comparison result, then the water quality data retrieved by the management and control platform is the time period from 8:00 to 8:20 according to the preset frequency The retrieved water quality data.

Step 103, comparing each water quality data with the preset content value, and based on the comparison result between the target water quality data and the preset content value, at the discharge time corresponding to the target water quality data, control the preset pumping and drainage equipment to discharge rainwater ; Wherein, the target water quality data refers to any water quality data, and the discharge time refers to the corresponding moment when the comparison result between the target water quality data and the preset content value is obtained.

In the implementation, the supervision platform compares all the water quality data retrieved when the liquid level comparison result is the first comparison result with the preset content value one by one, and each water quality data will get a water quality value when compared. The comparison results, each time the water quality comparison results are obtained is the discharge time; when the monitoring platform determines the water quality comparison results corresponding to the target water quality data, according to the specific content of the aforementioned water quality comparison results, in the corresponding Determine the specific discharge method at the time of discharge, and issue a drainage command to the drainage equipment, so that the drainage equipment will discharge water according to the determined discharge method at the corresponding discharge time.

Specifically, in step 103, "based on the comparison result of the target water quality data and the preset content value, at the discharge time corresponding to the target water quality data, control the preset pumping and drainage equipment to discharge rainwater" includes the following sub-steps:

If there is the first water quality data, then at the discharge time corresponding to the first water quality data, control the preset pumping and drainage equipment to discharge rainwater; wherein, the first water quality data refers to water quality data higher than the preset content value, and the inner discharge refers to rainwater Discharge into the preset treatment pool;

If there is second water quality data, then at the discharge time corresponding to the second water quality data, control the preset pumping and drainage equipment to discharge rainwater, wherein, the second water quality data refers to the water quality data not higher than the preset content value, and the discharge refers to Rainwater drains into the river.

In the implementation, the monitoring platform presets the discharge state, which includes internal discharge and external discharge. The default discharge state is internal discharge. If the monitoring platform shows the first water quality data in the process of comparing the water quality data with the preset content value, The supervision platform switches the discharge state to internal discharge, otherwise, the supervision platform switches the discharge state to external discharge, and then when the supervision platform determines that there is the first water quality data, it starts the internal discharge pump at the discharge time corresponding to the first water quality data. Perform internal discharge; similarly, when the monitoring platform determines that there is the second water quality data, at the discharge time corresponding to the second water quality data, start the external discharge pump for external discharge.

It should be noted that the duration of each external or internal discharge is determined by each water quality comparison result and each liquid level comparison result. If the liquid level comparison result is the period of the first comparison result, the existing If there is a second water quality data in the first water quality data, then the internal discharge time is the time period when the liquid level data is higher than the first liquid level value, and the water quality data is the first water quality data, and the external discharge time is the liquid level data During the period when the water quality data is higher than the first liquid level value, and the water quality data corresponds to the second water quality data, the management and control platform can use the time and duration of the external discharge corresponding to each external discharge, and the internal discharge time corresponding to each internal discharge. The discharge time and internal discharge duration are stored in the preset discharge duration table.

Optionally, the above rainwater discharge monitoring and control method also includes the following steps:

If the liquid level data is higher than the preset second liquid level value, and the water quality data is not obtained at the early warning time, the rainwater inward drainage is controlled; wherein the second liquid level value is greater than the first liquid level value, and the early warning time indicates The acquisition time corresponding to when the obtained liquid level data is higher than the second liquid level value, and the inner discharge refers to the discharge of rainwater into the preset treatment pool.

In implementation, in order to reduce the situation that the sump overflows, the supervision platform also stores the second liquid level value in advance, and the liquid level corresponding to the second liquid level value is higher than the first liquid level value; if the supervision platform sets the target After the liquid level data corresponding to the acquisition time is compared with the first liquid level value, the liquid level data obtained is higher than the first liquid level value. At this time, the monitoring platform will obtain the water quality data detected by the water quality testing equipment. The level data is compared with the second liquid level value. If the above liquid level data is greater than the second liquid level value, and when the above liquid level comparison result is obtained, the monitoring platform is not at the warning time due to water quality detection equipment failure and other reasons. If the water quality data is obtained, then the supervision platform will determine the discharge status as internal discharge before the water quality data is obtained, and issue an internal discharge command to the drainage equipment, so that the drainage equipment will discharge internally until the supervision platform receives When collecting water quality data, the discharge status is determined according to the water quality comparison results, and then the rainwater in the sump is discharged based on the discharge status.

Optionally, after the sump is used for a long time, the pollutants in the sump tend to remain and accumulate on the inner wall of the sump to form scaling, or the acidic or corrosive pollutants in the sump will also corrode the inner wall of the sump Therefore, the inner wall of the sump needs to be cleaned regularly, but the operator cannot determine whether or when the sump needs to be cleaned. For this reason, the rainwater discharge monitoring and management method of the present application also includes the following steps :

In conjunction with accompanying drawing 3, the sump includes the sidewall area and the inner circle area, and the water quality data includes the side wall area data and the inner circle area data;

If the rate of change between the liquid level data acquired at the target acquisition time and the liquid level data acquired at the previous acquisition time is lower than the preset speed, the side wall area data and the inner circle area data corresponding to the target acquisition time are acquired;

If the data of the side wall area and the data of the inner circle area obtained corresponding to the target acquisition time satisfy: the data of the side wall area is greater than the data of the inner circle area, and the difference between the data of the side wall area and the data of the inner circle area is greater than the preset difference, then generate and Display cleanup information.

In practice, there may be multiple water quality testing devices, which are used to detect the water quality data of the side wall area and the water quality data of the inner circle area respectively. The first water quality data in step 103 refers to both the side wall area data and the inner circle area data. Corresponding water quality data when the content is higher than the preset content value, correspondingly, the second water quality data refers to water quality data corresponding when neither the data of the sidewall area nor the data of the inner circle area is higher than the preset content value.

The management and control platform will calculate the change speed of the liquid level data corresponding to the adjacent acquisition time based on the liquid level data acquired at each acquisition time, and the change speed = the difference of the liquid level data at the adjacent acquisition time/the time of the adjacent acquisition time difference; then the management and control platform compares the calculated change speed with the preset speed. If the change speed corresponding to the target acquisition time is lower than the preset speed, it is determined that the rainwater in the current collection tank is relatively static. At this time, the control The platform compares the data of the side wall area corresponding to the target acquisition time with the data of the inner circle area. If the data of the side wall area corresponding to the target acquisition time is greater than the data of the inner circle area, and the difference between the data of the side wall area and the inner circle area If the value is greater than the preset difference, it means that there is accumulation of pollutants on the inner wall of the sump and the data in the inner wall area is higher than the data in the inner circle area. At this time, the management and control platform will generate and display cleaning information to inform the operator that the inner wall of the sump needs to be cleaned.

Optionally, the rainwater discharge monitoring method of the present application also provides another method for determining whether the inner wall of the sump needs to be cleaned, and the specific steps are as follows:

Every specified period of time, obtain the liquid level data at the previous moment and the liquid level data at the current moment, and obtain the inflow of water into the sump and the output of water out of the sump within the specified period of time. Among them, the time difference between the previous moment and the current moment The value is the specified duration;

Based on the liquid level data at the previous moment and the water inflow and outflow within a specified period of time, the ideal water level corresponding to the current moment is determined. The ideal water level at the current moment = the liquid level data at the previous moment + |water inflow - water outflow|/ The cross-sectional area of the sump;

If the liquid level data at the current moment is higher than the ideal water level at the current moment, a warning message for inner wall deposition will be generated and displayed;

If the liquid level data at the current moment is lower than the ideal water level at the current moment, an inner wall corrosion warning message will be generated and displayed.

In the implementation, the specified duration can be 24 hours, and the management and control platform can obtain the liquid level data at the current moment every specified duration, and retrieve the liquid level data at the previous moment from the preset liquid level storage table. = current moment - specified duration; As can be seen from the previous article, the management and control platform stores the duration of each internal discharge and the duration of each external discharge in the preset discharge time table, and the management and control platform can be based on the discharge time. The internal discharge time and external discharge time recorded in the table are calculated to obtain the sum of all internal discharge durations and external discharge durations within the time range corresponding to the previous moment to the current moment, that is, the total discharge time, and then the management and control platform is based on the preset The discharge volume of the pumping and drainage equipment in the unit time is calculated to obtain the water output, the water output = the total discharge time * the discharge volume in the unit time. In addition, a flow meter can be pre-installed at the water inlet pipe of the sump, and the management and control platform receives it in real time. Store the flow data and the corresponding receiving time, and then calculate the water inflow within the corresponding time range from the previous moment to the current moment.

Then, the management and control platform calculates the ideal water level corresponding to the current moment. The ideal water level refers to the water inflow and outflow from the previous moment to the current moment. Based on the liquid level data corresponding to the previous moment, the sump pool should reach The ideal water level at the current moment = the liquid level data at the previous moment + | water intake - water output | / cross-sectional area of the sump, where the management and control platform pre-stores the size information of the sump, which includes the size of the sump length, width and height.

Finally, the management and control platform compares the ideal water level at the current moment with the liquid level data detected by the water quality testing equipment at the current moment. If the liquid level data at the current moment is higher than the ideal water level at the current moment, it means that there is sediment on the inner wall of the sump , the sediment occupies a certain space in the sump, which makes the liquid level data detected by the water quality testing equipment higher than the ideal water level. Similarly, if the inner wall of the sump is corroded by acidic or corrosive pollutants, the inner wall of the sump will be Holes appear, and part of the rainwater flows into the holes to reduce the water level, so that the liquid level data detected by the water quality testing equipment is lower than the ideal water level; when the above two situations occur, it means that the inner wall of the sump needs to be cleaned or repaired. The real-time management and control platform will generate and display the warning information of inner wall deposition or inner wall corrosion warning information.

Optionally, in order to allow the operator to further know the volume of the sediment when they know that the inner wall of the sump has deposited "Specifically, it also includes the following sub-steps:

If the liquid level data at the current moment is higher than the ideal water level at the current moment, then based on the liquid level data at the current moment, the ideal water level at the current moment, and the size information of the sump, determine the sediment volume at the current moment, generate and display a Warning message for deposits on the inner walls of the object volume.

In practice, the volume of rainwater corresponding to the height of the water level at which the liquid level data at the current moment is higher than the ideal water level at the current moment is the sediment volume. Specifically, the sediment volume = cross-sectional area of the sump * (liquid level at the current moment data - the ideal water level at the current moment).

Optionally, before the above step of "displaying the inner wall deposition warning message with the sediment volume", it may further include:

Obtain the water quality data corresponding to the current moment, and based on the preset pollutant discharge per unit time, determine the total pollutant discharge and the total pollutant discharge within the specified time period. Among them, the total pollutant discharge within the specified time period Quantity = working hours of pumping and drainage equipment within a specified period of time * pollutant discharge per unit time, the total amount of pollutants within a specified period of time = water quality data at the current moment + total pollutant discharge within a specified period of time;
