Abstract

The invention discloses a composite microbial preparation with a biodegradable flocculant. The composite microbial preparation with the biodegradable flocculant comprises the following components in parts by mass: 30 parts of Bacillus coagulans with the strain number of CGMCC1.10302, 20 parts of Bacillussubtilis with the strain number of CGMCC1.15792, 10 parts of Cellulase with the concentration of 8000U / g and 140 parts of amylaceum. The composite microbial preparation with the biodegradable flocculant is successfully developed by screening high-performance Bacillus and an enzyme preparation and performing scientific compatibility aiming at the characteristics of the biodegradable flocculant, and can quickly raise the sludge fermentation temperature, kill harmful microorganisms in sludge and quickly decompose the sludge through fermentation under the normal sludge high-temperature fermentation production management condition.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a composite microbial preparation with a biodegradable flocculant and a preparation method thereof. Background technique [0002] Flocculants are widely used in water supply, industrial wastewater, urban sewage and sludge dehydration, post-treatment of fermentation industry, food industry and other fields. Traditional flocculants are inorganic flocculants and synthetic organic polymer flocculants. Inorganic flocculants are mainly two systems of iron salt and aluminum salt, and organic polymer flocculants are mainly polyacrylamide and its derivatives. At present, polyacrylamide is mostly used, which has the characteristics of less dosage and fast flocculation speed. However, because the monomers used to synthesize these polymers have strong neurotoxicity and strong "three-effect" effect, its application The scope is limited. [0003] Microbial flocculants (Micr...
