FIG. 1: the invention has a structure and a flow diagram;
Detailed Description
For further understanding of the contents, features and effects of the present invention, the following embodiments are enumerated in conjunction with the accompanying drawings, and the following detailed description is given:
referring to the attached figure 1, the invention firstly aerates and oxygenizes the condensed water body to ensure that the content of Dissolved Oxygen (DO) in the water body meets the water quality standard (generally, in 24 hours, 16 hours and more must be more than 5mg/L, and the rest must not be less than 3 at any time). Then, the water quality temperature (T) and the pH value (pH) are adjusted to the optimum growth range of the cultured organisms (generally, the culture temperature is 18-35 ℃ which is the normal temperature, 15-35 ℃ which is the optimum growth temperature, the pH value is 6.5-8.5 of fresh water, and 7.0-8.5 of seawater). Then, the content of nitrogen and phosphorus elements in the water is adjusted, and the main water quality index is ammonia Nitrogen (NH)4-N), nitrate nitrogen (nitrate (NO)3 --N) and Nitrite (NO)2 --N)) and active Phosphate (PO)4 3--P) and other water quality indexes, so that the water quality indexes meet the culture standard (NH)4-N concentration not exceeding 0.02mg/L, NO2 —The N concentration is not more than 0.02mg/L, PO4 3—The concentration of P is not more than 0.05 mg/L);
if the cultivation behavior is fresh water cultivation, and after the flora colony is properly adjusted, the production cultivation and other works can be carried out; if the cultivation behavior is mariculture, the production cultivation and other works can be carried out after the adjustment of flora and the adjustment of water salinity according to the optimal growth range required by the cultivated organisms. The method for adjusting the flora community can adopt the conventional method for sterilizing the culture water body.
Example 1:
in this embodiment, the baume degree of the industrial condensed water is about 5 degrees, the total number of the experimental research objects is 40 sea bass purchased in the market, and the total number of the south America white shrimps is 85.
The test method comprises the following steps:
and measuring various water quality indexes of the vacuum salt-making industry condensate water and brine, including temperature, salinity, pH value, nitrite nitrogen, ammonia nitrogen and the like. And after measurement and analysis, adjusting the temperature and the pH value of the mixed water body. And then, carrying out optimization treatment on the water quality index, mainly comprising the work of using a protein separator, filtering by using filter cotton, aerating and the like. Finally, the test brine and the vacuum salt-making industrial condensate water are proportioned according to the salinity of 30 per mill according to the water treatment process. After the proportioning work is finished, the water quality index of the proportioning water body is measured, and the cultivation is carried out after the water quality index meets the standard. The obtained water quality index is shown in Table 1.
TABLE 1 Water quality index for test
As can be seen from Table 1, the quality indexes of the I-effect condensed water all meet the water quality standards, the content of ammonia nitrogen and nitrite in the quality indexes of the II-effect condensed water and the III-effect condensed water is high, and the quality of the mixed water body all meets the standards after the II-effect water and the III-effect water are subjected to water quality purification treatment and are proportioned and mixed.
Biological indexes are as follows:
TABLE 2 biological indices of cultivation
In the preliminary test, both the sea bass and the penaeus vannamei boone can carry out normal physiological activities in the water body with the ratio of the brine to the I-effect condensed water, and as can be seen from table 2, the survival rate of the sea bass and the penaeus vannamei boone is less than 90% within 48 hours of the culture time, and the reason may be that the self activity state of the sea bass and the penaeus vannamei boone is poor and the health force is insufficient. Meanwhile, stress is generated on the biological cell in the transportation process, and the biological cell is stressed; however, when the influence caused by stress is not completely relieved, a new stress source is added, so that the stress is excessive, the regulation is disordered, and finally the death is caused. But the culture time exceeds 48 and 96 hours, and the survival rate of the two cultured organisms can reach 100 percent.
And (4) conclusion:
after the test brine and condensed water in the vacuum salt manufacturing industry I, II and III are subjected to proportioning, purification and other treatment, the dissolved oxygen content, the temperature, the salinity, the pH value, the ammonia nitrogen concentration and the nitrite concentration in the water quality indexes all accord with the water quality standard, the normal physiological activity of the breeding organisms can be provided, and the obvious difference with individuals actually subjected to production and breeding is avoided.
The water treatment technology is verified to be capable of effectively combining brine with the condensate water in the vacuum salt-making industry, so that the brine can be used as a substitute of seawater and even fresh water for the normal physiological activities of the breeding organisms. The water treatment technology combines industrial clean waste with agricultural production and cultivation, and further ensures normal physiological activities and production and breeding of aquaculture organisms on the basis of energy conservation, environmental protection and cyclic utilization.
