Composite microbiological preparation for governing black-odor river and preparation method and application thereof

Abstract

The invention discloses a composite microbiological preparation for governing a black-odor river, a preparation method and application in governance of the black-odor river. The composite microbiological preparation comprises photosynthetic bacterium, nitrifying bacterium, thiobacillus denitrificans, bacillus subtilis and candida. The preparation method has the advantages that the composite microbiological preparation is prepared from a variety of strains, and all the strains are reasonable in proportion, capable of being symbiotic and free of antagonistic effect; the carrier of the composite microbiological preparation is formed by wheat bran, saw powder, activated carbon and brick powder, and is easy to acquire and low in cost; the composite microbiological preparation is extensive in application and high in removal efficiency on nutritive salt ingredients in the black-odor river, such as nitrogen and phosphorus; the composite microbiological preparation has an obvious eliminating effect on odor gas sulfuretted hydrogen in the black-odor river; the composite microbiological preparation is high in activity, rapid in reproduction, environmentally friendly and free of secondary pollution.

Description

technical field [0001] The invention belongs to the field of treatment of black and odorous water bodies, and in particular relates to a compound microbial preparation for treatment of black and odorous rivers, a preparation method and application thereof. Background technique [0002] Urban water bodies such as rivers are an important part of urban ecosystems. They have the characteristics of small water environment capacity, poor water self-purification ability, and easy pollution. They are often used as important sewage discharge and sewage channels in cities, and water quality is more likely to deteriorate. The influx of a large amount of pollutants has led to serious eutrophication of urban water bodies, resulting in a sharp consumption of dissolved oxygen in water bodies, resulting in long-term hypoxia in water bodies and resulting in black and odorous states. Black and odorous water bodies in cities such as rivers have become a common phenomenon in Chinese cities, ser...

AI Technical Summary

Problems solved by technology

However, in the application process of microbial agents in the treatment of black and odorous water bodies, there are often problems such as weak degradation ability to nitrogen, phosphorus and organic matter and other pollutants, low treatment efficiency, and ineffective elimination of odor gas hydrogen sulfide in black and odorous water bodies.
