Description
Technical Field
The invention relates to the field of water environment treatment, in particular to a method for removing pollutants in a water body and a water body treatment system.
Background
The landscape water body is an important component of urban environment, the wastewater of the living, agricultural and aquaculture industries is rich in nitrogen, phosphorus and organic matters, and the wastewater can be discharged into the landscape water body if the wastewater is not treated or does not reach the standard, so that the landscape water body can be eutrophicated, and black and odorous water or water bloom is formed. Especially, the water bodies received in lakes, reservoirs, ponds and the like are extremely sensitive to eutrophication due to the closed or semi-closed nature, and black and odorous water and severe water bloom are very easily formed.
The treatment of receiving water is a very headache problem. Firstly, it is difficult to avoid that the upstream feed water is completely up to standard; secondly, even if the problems are temporarily solved by physical and chemical means such as flocculation, salvaging and the like after the black smelly water or the bloom is formed, the eutrophication nature of the water body is not changed, and microorganisms continue to breed to form the black smelly water or the bloom again. Therefore, the water quality evaluation standard of the receiving water body is higher than that of the flowing water body.
At present, the black smelly water and the water bloom water are treated by a biological method. The biological method mainly comprises artificial wetland treatment, aquatic plant restoration, microorganism restoration and the like. The artificial wetland treatment needs additional treatment environment, the cost is huge, and the artificial wetland treatment is particularly not suitable for receiving water bodies with multiple inlets. The aquatic plants can not grow in the black and odorous water and the water bloom water body, even if luxuriant aquatic plants are initially arranged in the water body, the eutrophic water quality can convert the water body into water body which is not suitable for plant growth in a short time, and further the black and odorous water or the water bloom is formed. Microbial remediation is a relatively effective treatment method at present. The invention patent application with the name of composite microbial preparation for water body restoration, preparation method and application thereof, and application number of 2014103851867, which is filed in 2014 by the applicant, discloses a composite microbial preparation for water body restoration. The microorganism released by the microbial preparation put into water can be rapidly propagated and metabolize organic matters, nitrogen and phosphorus in the sewage. However, for receiving water bodies, simple microbial agent delivery does not completely solve the problem. Because the microorganisms still remain in the water body after absorbing nitrogen and phosphorus, when the microorganisms die, cell bodies are decomposed to release nitrogen and phosphorus again, and the problem of water body eutrophication is still solved.
Therefore, a need exists for a remediation system and method for use with a receiving body of water.

4. Treatment results
After the water body treatment system is used from the end of 2018, the water quality of the lotus lake rapidly becomes clear by the end of 2019, 1 month and 1 month, the concentration of nitrogen and phosphorus is greatly reduced, and by the end of 2019, 6 months, the blue algae bloom is not generated in the lotus lake any more, like the former year, the concentration of nitrogen and phosphorus is monitored at a plurality of sampling points in the treatment process, wherein the concentration of nitrogen and phosphorus at four different sampling points is changed as shown in table 1 and figures 7-9, the concentration of nitrogen and phosphorus is greatly reduced when the treatment time is less than two months, the content of ammonia nitrogen is basically controlled to be less than 0.2 mg/L under the condition of continuous sewage discharge, the content of total nitrogen is basically controlled to be less than 2.0 mg/L, the content of total phosphorus is basically controlled to be less than 0.05 mg/L, if no sewage is continuously discharged, the treatment system can control the content of ammonia nitrogen to be less than 0.10 mg/L, the content of total nitrogen is controlled to be less than 1.5 mg/L and the content of total phosphorus is close to 0.6g of microorganism per day.
In addition, only a microorganism attachment device is arranged and microbial preparations are put in, but the microorganism attachment device is replaced irregularly to treat a highly polluted pond, the nitrogen and phosphorus concentration in the pond is rapidly reduced in the early treatment stage, the condition lasts for 10-15 days, the ammonia nitrogen content is reduced from 4.3 mg/L to about 1.3 mg/L, the total nitrogen content is reduced from 6.7 mg/L to about 3.6 mg/L, the total phosphorus content is reduced from 0.3 mg/L to about 0.2 mg/L, then the nitrogen and phosphorus concentration is continuously stable and cannot be further reduced, and the reason is presumed to be that microorganisms except nitrogen and phosphorus start to die and disintegrate and release a large amount of nitrogen and phosphorus, so that the balance of absorption and release is formed.
