Abstract

The invention discloses a compound microorganism combination microbial agent, a preparation method and application thereof, a sludge treatment method for a black-odor river. The compound microorganism combination microbial agent comprises the three kinds of microbial agent combinations of a microbial agent A combination, a microbial agent beta combination and a microbial agent gamma combination, and the microbial agent A combination comprises the microbial strains of bacillus coagulans, lactic acid bacteria, saccharomycetes, aspergillus sojae and thiobacillus denitrificans; the microbial agent beta combination comprises the microbial strains of lactic acid bacteria, bacillus subtilis, photosynthetic bacteria and saccharomycetes; and the microbial agent gamma combination comprises the microbial strains of lactic acid bacteria, bacillus subtilis, saccharomycetes, bacillus licheniformis and bacillus coagulans. The compound microorganism combination microbial agent can be used for treatment of bottom mud of the black-odor river, the treatment period is short, the thickness of the bottom mud can be effectively reduced, the content of harmful matters in the bottom mud is reduced, the situation that nitrogen and phosphorus of a black and odorous water body exceed a standard can be solved, and odorous gas hydrogen sulfide in the water body can be eliminated.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a compound microbial composition bacterial agent, a preparation method and application thereof, and a method for treating sludge of 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 Chi...
