BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wastewater purification apparatus for a car wash capable of reusing wastewater discharged from a car wash as car wash water.

As the supply of vehicles increases rapidly, wastewater generated during the car wash for the management of these vehicles is becoming a social problem.

In the case of a car wash that specializes in car wash, the wastewater purification system has been used to purify and discharge the wastewater to the sewerage to the extent that it meets the emission standards for wastewater used for car washing.

However, since the waste water is purified and discharged at a high cost and the tap water is used for washing, a car washer recycling apparatus for recycling wastewater generated in a car wash to reduce purification cost and water supply has been proposed.

FIG. 3 is a front view showing the internal structure of the main body in the car washer / wastewater purification apparatus of the present invention, FIG. 4 is a side view showing the internal structure of the main body in the car washer / Fig. 6 is a schematic view showing a structure of a wastewater purification apparatus for a car wash according to the present invention. Fig.

An apparatus for purifying a wastewater for a car wash comprises a settling tank (110); (120); A recycling tank 130; A new water tank 140; A main body 200; A chemical liquid tank 210; A chemical liquid pump 220; And a chemical liquid supply pipe (230).

In the settling tank 110, wastewater discharged from a car wash is collected to deposit foreign matter such as dust, sand, etc. contained in wastewater.

The water tank separator 120 is installed adjacent to the sedimentation tank 110, and the supernatant having foreign matter precipitated from the sedimentation tank 110 flows over and removes the oil contained in the supernatant.

The recycling tank 130 is installed adjacent to the water separation tank 120 to allow the water separated from the water separation tank 120 to pass through and to be purified by the carrier.

The fresh water tank 140 is installed adjacent to the recycling tank 130 and collects purified water from the recycling tank 130. The water collected in the new water tank 140 is recycled as wash water for washing.

Inside the main body 200, a chemical liquid tank 210 and a chemical liquid pump 220 are provided. In addition, the main body 200 is provided with a control unit for controlling and monitoring the chemical liquid pump 220, the ring blower 250, the compressor operation, and the like.

The chemical liquid tank 210 is provided in the main body 200 and stores a chemical liquid containing microorganisms and enzymes. The chemical liquid containing the biologic and enzymes is supplied to the sedimentation tank 110, the water separation tank 120, the recycling tank 130, and the fresh water tank 140 to remove pollutants contained in the wastewater discharged from the car wash Decomposition to fundamentally solve the cause of the odor, and to purify the wastewater.

The chemical liquid pump 220 is provided in the main body 200 and supplies the chemical liquid from the chemical liquid tank 210 to the settling tank 110, the water separator tank 120, and the recycling tank 130 . The chemical liquid pump 220 is a metering pump and pumps a certain amount of chemical liquid.

The chemical solution supply pipe 230 serves to supply a chemical solution pumped by the chemical solution pump 220 to the sedimentation tank 110, the water separation tank 120 and the recycling tank 130, respectively.

When the chemical liquid pump 220 supplies the chemical liquid to the settling tank 110, the water separator tank 120, and the recycling tank 130, it is preferable that the chemical liquid pump 220 adjusts and supplies the chemical liquid having a constant concentration corresponding to the water level.

To this end, the water level sensor 150 and the solenoid valve 240 of the present invention are used.

The water level sensor 150 is provided in the sedimentation tank 110, the water separation tank 120, the recycling tank 130, and the fresh water tank 140, respectively.

The solenoid valve 240 is provided in the main body 200 and is installed on each of the chemical liquid supply pipes 230 and is connected to the sedimentation tank 110, The recycle tank 130, and the fresh water tank 140. [0031] The control unit 120 controls the amount of the chemical liquid supplied to the recycling tank 130 and the fresh water tank 140. [ At this time, the solenoid valve 240 adjusts the amount of the chemical liquid supplied by adjusting the opening / closing time of the amount of the chemical liquid supplied from the chemical liquid pump 220 according to the level sensed by the water level sensor 150. The amount of the chemical solution is the largest in the sedimentation tank 110 and becomes smaller as it goes to the water separation tank 120, the recycling tank 130, and the new water tank 140.

In the case of car washes, most of them do not operate full 24 hours. Therefore, if the water contained in the sedimentation tank 110, the water separation tank 120, and the recycling tank 130 becomes too high, it may cause bad odors and deteriorate water quality. In order to reduce such odor generation and water deterioration, the present invention employs a ring blower 250 and an air supply pipe 260.

The ring blower 250 is installed in the main body 200 and generates air to be supplied to the sedimentation tank 110, the water separation tank 120, and the recycling tank 130.

The air supply pipe 260 transfers the air generated by the ring blower 250 to the sedimentation tank 110, the water separation tank 120 and the recycling tank 130 to remove the sedimentation tank 110, And serves to aerate the water contained in the trough 120 and the recycling tank 130.

At this time, the ring blower 250 is operated by a timer to generate air intermittently and air is sent to the air supply pipe 260 to be supplied to the sedimentation tank 110, the water separation tank 120 and the recycling tank 130 To allow the water contained therein to be aerated. If the water contained in the sedimentation tank 110, the water separation tank 120, and the recycling tank 130 is aerated, the cause of the odor can be fundamentally removed and the water quality can be further improved by increasing the dissolved oxygen .

In the case of car washes, most of them are installed outdoors. Therefore, it is often the case that the pipeline is frozen in the sub-zero winter.

In order to prevent the piping of the present invention from being frozen, a compressor and a compressed air supply pipe 270 are adopted.

The compressor (not shown) serves to generate compressed air.

The compressed air supply pipe 270 serves to supply the compressed air generated by the compressor to the chemical solution supply pipe 230 provided at the front end of the solenoid valve 240 to supply the compressed air.

When the compressed air generated by the compressor is transferred to the chemical liquid supply pipe 230 through the compressed air supply pipe 270, the solenoid valve 240 is opened so that all the chemical liquid remaining in the chemical liquid supply pipe 230 is discharged to the sedimentation tank 110, the water separator tank 120, and the recycling tank 130 so that the inside of the chemical liquid supply pipe 230 becomes empty, thereby preventing frost.

At this time, a water temperature sensor (not shown) is provided in the sedimentation tank 110, the water separation tank 120, the recycling tank 130, and the fresh water tank 140. By the water temperature sensor, When the temperature is sensed, it is preferable to operate the compressor to empty the chemical liquid supply pipe 230.

The operation of the apparatus for cleaning a wastewater for a car wash according to the present invention will now be described.

The wastewater used in the car wash is collected in the settling tank 110 to deposit foreign matter such as dust and sand contained in the wastewater. The wastewater in which the impurities are precipitated is swirled by the supernatant in which the impurities are precipitated in the distillation tank 120 installed adjacent to the settling tank 110 and the oil contained in the supernatant is removed. The wastewater from which the oil is removed from the water separation tank 120 is transferred to the recycling tank 130 provided adjacent to the water separation tank 120 and purified by the carrier contained in the recycling tank 130.

The new water tank 140 is installed adjacent to the recycling tank 130 and collects purified water from the recycling tank 130 and the water collected in the new water tank 140 is recycled as wash water for car washing .

The chemical liquid containing the microorganisms and the enzyme stored in the chemical liquid tank 210 is supplied to the sedimentation tank 110, the water tank separator 120, the recycling tank 130, And the new water tank 140, respectively, so as to purify the wastewater.

The water level sensor 150 is provided in the settling tank 110, the water tank separating tank 120, the recycling tank 130 and the fresh water tank 140, The amount of the chemical liquid supplied to the sedimentation tank 110, the water separator tank 120, the recycling tank 130, and the fresh water tank 140 is controlled by opening and closing the solenoid valve 240.

The air generated by the ring blower 250 provided in the main body 200 is supplied to the sedimentation tank 110, the water separation tank 120 and the recycling tank 130 through the air supply pipe 260 So that the water contained in the settling tank 110, the water tank separator 120 and the recycling tank 130 is discharged to the outside through the circulating tank 110, So that odor generation and water quality deterioration can be reduced.

In the case of the winter season, the compressed air generated by the compressor is transferred to the chemical liquid supply pipe 230 through the compressed air supply pipe 270 so that all the chemical liquid remaining in the chemical liquid supply pipe 230 flows into the settling tank 110, So that the water is drained to the water separation tank 120, the recycling tank 130, and the fresh water tank 140 so that the inside of the chemical liquid supply pipe 230 becomes empty to prevent frost.
