Problems solved by technology

[0003] At present, microbial methods are often used to treat polluted water bodies, and many microbial methods use a single biological bacteria to treat polluted water bodies, which makes the survival rate and activity of microbial bacteria low, and it is also difficult to restore the self-purification ability of water bodies

Abstract

The invention discloses a method for applying a composite microbial agent to treating a water body. The method comprises the following steps: 1) the pollution indexes of water quality are detected, and the pollution degree of the water quality is analyzed and classified; 2) strains are matched and combined according to the water quality types obtained in the step 1), and a composite microbial agent is formed; 3) the composite microbial agent obtained in the step 2) is mixed with natural mineral powder and the mixture is put into the sewage; 4 ) the step 1), the step 2) and the step 3) are repeated to meet the standard requirement. The composite microbial agent is formed by combining two or more than two kinds of microorganisms including bacillus subtilis, bacillus licheniformis, bacillus coagulans, photosynthetic bacteria, lactic acid bacteria, saccharomycetes, phosphorus accumulating bacteria, nitrifying bacteria and denitrifying bacteria.

Description

technical field [0001] The invention relates to a method for controlling pollution, in particular to a method for applying a compound microbial bacterial agent in water treatment. Background technique [0002] Water is the source of human life and is irreplaceable. Statistics show that the total amount of water resources in my country is 2.8 trillion m 3 , ranking sixth in the world. But the per capita water resource is only 2240m 3 , less than 1 / 3 of the world average level. The increase in the number and types of pollutants brought about by my country's rapid economic development is in conflict with the lag of water treatment facilities and the ineffective control of point source pollution, resulting in excessive sewage or even direct discharge into natural water bodies, causing a sharp decline in water quality. What is even more worrying is that the increasingly serious environmental pollution is threatening the drinking water source on which human beings depend for s...
