Biochemical system sludge reduction microbial compound bacteria, preparation method thereof and application of biochemical system sludge reduction microbial agent

Abstract

The invention discloses a microbial compound bacterium for reducing sludge of a biochemical system, a preparation method of the microbial compound bacterium and application of a microbial agent for reducing the sludge of the biochemical system, belongs to the field of sewage treatment and microorganisms, and solves the problem of how to realize low cost and no secondary pollution or solid waste. In order to solve the problem of reducing the residual sludge in the sewage treatment process, the invention discloses a method for preparing the sludge reduction agent from bacillus smithii with the preservation number of CGMCC (China General Microbiological Culture Collection Center) No.31841. The preservation number of the Heynickia coagulans is CGMCC (China General Microbiological Culture Collection Center) No.31842, and the preservation number of the Heynickia coagulans is CGMCC No.31842 The invention relates to xylose-decomposing bacillus paraceticus, the preservation number of which is CGMCC (China General Microbiological Culture Collection Center) No.31844, and the preservation number of which is bacillus paraceticus No.31844. The invention further discloses a preparation method of the xylose-decomposing bacillus paraceticus. The bacillus pallidus has the preservation number of CGMCC (China General Microbiological Culture Collection Center) No.31845, and the preservation number of the bacillus pallidus is CGMCC No.31845. According to the present invention, with the application of the microbial compound bacteria and the microbial agent composed of the Pallidibacillus thermomolactis with the preservation number of CGMCC No.31847 to the biochemical system, the reduction of the excess sludge in the sewage treatment process is achieved from the source, and the advantages of high activity, low investment, low energy consumption, convenient operation and no secondary pollution are provided, wherein the microbial compound bacteria and the microbial agent comprise the Pallidibacillus thermomolactis and the preservation number of the Pallidibacillus thermomolactis.
