Composite microbial preparation capable of efficiently degrading organic waste and application thereof

Abstract

The invention discloses a composite microbial preparation capable of efficiently degrading organic waste and application thereof. The composite microbial preparation contains white-rot fungus, penicillium diversum, pseudomonas putida, alcaligenes faecalis, bacillus subtilis and bacillus thuringlensis, wherein the bacterial count of the white-rot fungus accounts for 20-40% of the total bacterial count of the composite microbial preparation, the bacterial count of the penicillium diversum accounts for 5-15% of the total bacterial count, the bacterial count of the pseudomonas putida accounts for 10-20% of the total bacterial count, the bacterial count of the alcaligenes faecalis accounts for 5-15% of the total bacterial count, the bacterial count of the bacillus subtilis accounts for 10-20% of the total bacterial count, and the bacterial count of the bacillus thuringlensis accounts for 10-20% of the total bacterial count. The invention also provides the application of the composite preparation in sewage treatment. The composite microbial preparation has the advantages of being capable of rapidly decomposing organic waste, effectively inhibiting the growth of harmful microbes, enabling suspended matters in sewage to flocculate, reducing aeration rate, effectively improving sewage chromaticity and turbidity, eliminating stink and reducing sludge discharge.

Description

Technical field: [0001] The invention relates to the field of microbiology, in particular to a composite microbial preparation, in particular to a composite microbial preparation for efficiently degrading organic waste and its application. Background technique: [0002] At present, various wastewater biological treatment technologies introduce human and animal feces or excess sludge from large sewage plants, cultivate and domesticate microorganisms through sludge to reproduce a certain number of bacterial micelles, and then put them into normal operation. Although this method is low in cost, it generally has the following disadvantages that are difficult to overcome: [0003] (1) The quality of the effluent varies greatly, making it difficult to ensure continuous and stable discharge; and the ability to degrade characteristic pollutants such as cellulose and lignin in industrial wastewater from papermaking, brewing, and chemical industries is weak; [0004] (2) Sludge has p...
