Abstract

The invention belongs to the technical field of flocculant preparation, and discloses a method for preparing a high-efficiency flocculating agent by using compound microbial inoculum. The method comprises the steps of: strain cultivation, fermenting cultivation, sedimentation by using modified bentonite, drying and the like, wherein the compounding strain is obtained by compounding a fast-growingbacillus strain Celeribacter sp. GHF1031 and a white Rubrobacter strain Albirhodobacter sp. GHF1032 which are obtained through separation and purification of mud which is spit out by Ruditapes philippinarum. The flocculating agent which is obtained by using the corresponding method and the compound microbial inoculum which is prepared from the fast-growing bacillus strain Celeribacter sp. GHF1031and the white Rubrobacter strain Albirhodobacter sp. GHF1032 has the characteristics of a high flocculation rate, has stable performance, no toxic and side effects, high safety, simple production andlow cost at the same time, and can be used as a wastewater flocculating agent.

Description

technical field

[0001] The invention relates to the technical field of flocculant preparation, in particular to a method for preparing a high-efficiency flocculant by using a compound bacterial agent. Background technique

[0002] Flocculants are one of the commonly used agents in water treatment technology. In recent years, the most widely used traditional high-molecular polymer flocculants have been found to have potential problems that threaten human health and destroy the ecological environment. Research on new environmentally friendly and pollution-free flocculants has become a hot issue in water treatment research. Most of them are microbial flocculants. Bioflocculants are a class of polymers with biodegradable functions, including polysaccharides, lipids and proteins secreted by microorganisms with such special functions. Because of its safety and non-pollution to the environment, it is valued by many scientific researchers at home and abroad. At present, a variety...
