[0040]

[0041] The ultimate goal of water bioremediation is to make water meet the national standards for surface water and lake water quality. To achieve this goal, the environmental management department requires the control of three basic indicators of water bodies: ammonia nitrogen, total phosphorus, and transparency. According to the overall situation of water environmental pollution in my country, the content of ammonia nitrogen is usually set at Class II standard of surface water, 0.5 mg.L −1 ; The total phosphorus content is set at the lake water Class II...

Abstract

The invention discloses a management method of a eutrophic water body. The management method comprises the following steps: uniformly mixing bacillus subtilis, nitrifying bacteria and denitrifying bacteria according to a certain ratio to prepare a denitrification, dephosphorization and algal inhibition compound microorganism preparation, wherein the content of beneficial bacteria in the denitrification, dephosphorization and algal inhibition compound microorganism preparation is as follows: the content of the bacillus subtilis is greater than or equal to 8.0*10<8>cfu / g, the content of the nitrifying bacteria is greater than or equal to 2.0*10<6>cfu / g and the content of the denitrifying bacteria is greater than or equal to 2.0*10<6>cfu / g; directly and uniformly scattering potassium peroxymonosulfate sulfate compound salt grains into a water body to be managed, and directly scattering according to the dosage of 50 to 1000g / Mu / m, and keeping the water body on an electric potential of 500MV or more; after adding the potassium peroxymonosulfate sulfate compound salt and treating the water body for 12h, directly and uniformly scattering the denitrification, dephosphorization and algal inhibition compound microorganism preparation into the water body to be managed, and directly scattering according to the dosage of 50 to 500g / Mu / m. The preparation is directly added by phases and doesnot need to be aerated; the denitrification, dephosphorization and algal inhibition effect is obvious and water body electric potential balance, bacterium phase balance and algal phase balance and a self-purification capability of the water body is formed.

Description

technical field [0001] The invention belongs to the technical field of environmental treatment, and in particular relates to a method for water body treatment, especially for the treatment method of eutrophic water body. Background technique [0002] In recent years, with the increasing development and utilization of environmental resources, a large number of pollutants containing nitrogen and phosphorus nutrients have been continuously discharged into lakes, reservoirs and rivers, increasing the nutrient load of water bodies. On the other hand, in order to increase the yield of crops, the amount of chemical fertilizers and livestock manure applied to farmland has increased year by year, and the nutrients entering the water body have continuously increased through the erosion and infiltration of rainwater. Due to the influence of these human factors, the problems of water pollution and eutrophication are becoming more and more serious. The effective control of eutrophic wat...
