A sludge in-situ reduction biological agent and its preparation method and application

Abstract

The present invention relates to the technical field of sludge reduction biological treatment, and provides a sludge in-situ reduction biological preparation and its preparation method and application. The components of the biological preparation include a specific carbon source, a composite enzyme preparation, a composite bacterial agent and a phage concentrate; the specific carbon source includes polyvinyl alcohol, sodium alginate, polylactic acid and humus; the phage concentrate includes Bacillus phage, Coccidioides phage and Gordonia phage; the composite enzyme preparation includes lysozyme, α-amylase, phosphatase and β-glucosidase; the composite bacterial agent includes Bdellovibrio, Lactobacillus, Bacillus, Paenibacillus and yeast. The components of this biological preparation are optimized and enriched, and the sludge reduction effect is significant; when used, it can be directly put into wastewater without adding microbial carrier materials, without the need to transform the existing pool body, non-toxic and harmless, and eco-friendly.
