Abstract

The invention discloses a composite microbial agent and a preparation method and application thereof, and a treating method for a black and odorous river. The composite microbial agent comprises a microbial agent A composition, a microbial agent B composition and a microbial agent gamma composition, wherein the microbial agent A composition comprises Bacillus coagulans, lactic acid bacteria, saccharomycetes, Aspergillus sojae and Thiobacillus denitrificans; the microbial agent B composition comprises Bacillus coagulans, silicate bacteria, Bacillus firmus and lactic acid bacteria; and the microbial agent gamma composition comprises lactic acid bacteria, Bacillus subtilis, Saccharomyces, Bacillus licheniformis and Bacillus coagulans. The composite microbial agent provided by the invention can be used for treating black and odorous rivers, is short in treatment period, and can effectively solve the problem that nitrogen and phosphorus exceed the standard in black and odorous water and eliminate the odorous gas hydrogen sulfide in water.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a compound microbial composition bacterial agent, its preparation method and application, and a treatment method for black and odorous river courses. 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, se...
