Abstract

The invention provides a microbial preparation for repairing black and odorous water body bottom mud and a preparation method, and relates to the field of black and odorous water treatment. The microbial preparation comprises a porous carrier and composite microbial inoculants adsorbed on the porous carrier; the composite microbial inoculants comprise bacillus subtilis, nitrifying bacteria, bacillus, lactic acid bacteria and cellulose in a set ratio. The bacillus subtilis, nitrifying bacteria, bacillus and lactic acid bacteria for effectively decomposing organic matters in the black and odorous water body are screened out and are mutually influenced through bacterial colony proportioning to provide nutrients required by each other, so that the organic matters and the like in the black andodorous water body are stably consumed; the composite microbial inoculants are adsorbed on the porous carrier, and the porous carrier sinks into the black and odorous water body bottom mud, so that the inoculants can be continuously and slowly released, and the composite microbial inoculants are prevented from running off too fast along with water flow.

Description

technical field [0001] The invention relates to the field of treatment of black and odorous water bodies, in particular to a microbial preparation and a preparation method for repairing bottom sludge of black and odorous water bodies. Background technique [0002] Black and odorous water not only seriously affects the city's water landscape, but also brings unpleasant impressions to people; the loss of water functionality inhibits people's demand for hydrophilicity and water intake, and at the same time affects the health of surrounding residents, affecting people's respiratory system, The circulatory system and digestive system have adverse effects. Therefore, solving the pollution problem of urban rivers and restoring the ecological and social functions of rivers is not only related to the improvement of the overall image of the city, but also closely related to the health and life of residents. It is very necessary and urgent. [0003] The deposition and anaerobic fermen...
