Description

Emergency treatment method for rural black and odorous water body
Technical Field
The invention belongs to the technical field of sewage treatment biology, and particularly relates to an emergency treatment method for rural black and odorous water.
Background
The black and odorous water body is an extreme manifestation of organic matter pollution of the water body and is caused by oxygen deficiency and organic matter putrefaction of the water body. When a large amount of organic pollutants enter the water body, under the biochemical action of aerobic microorganisms, a large amount of oxygen in the water body is consumed, so that the water body is converted into an anoxic state, anaerobic bacteria are propagated in a large amount, and organic matters are decayed, decomposed and fermented to make the water body black and odorous.
The enzyme has a long-standing name, and is called "enzyme" in English, which is generally called "enzyme" in China. The enzyme is a biological catalyst, which can accelerate various biochemical reactions without changing the biochemical reaction itself. The use and the technological popularization to edible ferment are comparatively mature and common at present in the world, and environmental protection ferment is also starting to receive the attention of academic and develop further research in recent years as a novel ferment product that is used for environmental improvement and environmental protection. However, the current treatment effect using the environmental-friendly enzyme for sewage treatment is rarely reported, and the long-term treatment effect is not reported in many data researches.
