Composite microbial agent and application thereof in composting treatment of pathogen-infected animal carcasses

Abstract

The invention discloses a composite microbial agent and an application thereof in composting treatment of pathogen-infected animal carcasses. The composite microbial agent comprises mixed bacteria composed of acillus licheniformis and anoxybacillus beppuensis according to any proportion. The composite microbial agent can utilize different-stage physicochemical environments during a compost heaping process, overcomes adverse effects brought by inappropriate physicochemical properties, promotes rising of a pile temperature in a relay temperature rising manner, and effectively prolongs the duration time of a compost high temperature period. With combination of a mixed bacteria liquid culture medium provided by the invention, the composite microbial agent can be effectively applied to rapidly increase the compost pile body temperature, also is used for the composting treatment of the pathogen-infected animal carcasses, and improves the composting efficiency.

Description

technical field [0001] The invention relates to the field of treatment technology of infected animal corpses and microorganism technology, in particular to a composite microbial preparation capable of promoting compost heating. Background technique [0002] The livestock and poultry breeding industry has developed rapidly in recent years. While increasing the production of livestock and poultry, the industrialized and intensive breeding mode inevitably produces a large amount of pollutants, including breeding wastewater, livestock manure, and carcasses of sick and dead livestock. my country is a traditional large livestock and poultry breeding country. At present, my country's aquaculture industry produces about several billion tons of livestock and poultry manure every year. Since more than 80% of the breeding enterprises lack the ability to process or comprehensively utilize them, these livestock and poultry manures are harmful to the environment. It has caused serious har...

AI Technical Summary

Problems solved by technology

Since the composting process is greatly affected by factors such as raw material components and ambient temperature, the composting fermentation efficiency is low without the artificial addition of bacterial agents

At present, the research in this field is mainly focused on the bacteria agent used to promote the composting efficiency of domestic waste and livestock and poultry manure composting, but there is no bacteria agent specially used for composting infected animal carcasses
