Compost decomposition additive and application thereof

Abstract

The invention relates to a compost decomposition additive. The additive comprises, by mass, 100 parts of fresh brewer's grains, 5-15 parts of bran, 2-4 parts of ammonium sulfate, 10-20 parts of urea,0.5-1 part of potassium dihydrogen phosphate, 0.1-0.5 part of NaCl and a strain seed solution with the total volume 10-20% of the mass of the fresh brewer's grains, wherein the strain seed solution isa mixture of seed solutions of aspergillus niger, penicillium, ralstonia and candida utilis in the volume ratio of (2-3):(2-3):(1-2):(1-2). According to the additive, the fresh brewer's grains serveas a culture medium for primary fermentation under the symbiotic action of various microorganisms, the number of bacteria is increased, and cellulase is also generated for further decomposing cellulose; meanwhile, the cellulose can be effectively degraded through the symbiotic action of various kinds of cellulase, and organic decomposition of feces of livestock and poultry can be better promoted.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a compost decomposing additive and its application. Background technique [0002] With the rapid development of my country's large-scale livestock and poultry breeding industry, a large number of livestock and poultry manure has become a new source of pollution. High-temperature aerobic composting is an important way for the harmless treatment and fertilizer utilization of livestock and poultry manure. Traditional composting generally has a long fermentation cycle and low efficiency. In order to speed up the composting process, people often pretreat the compost raw materials. During the pretreatment process, the most commonly used method is to add microbial agents to the materials. According to reports, there are more than 2,000 manufacturers of microbial agents in my country, but different compound agents, different auxiliary materials and ratios lead to different composting effects,...

Problems solved by technology

Many farmers use it as good feed, but because of its good nutritional content and high water content, it is very easy to deteriorate and become rancid. Sometimes it will decompose pectin and formaldehyde during the fermentation process. These things are harmful to human body and human body. There are harmful substances in livestock and poultry, and if they eat them, they will get diarrhea and get sick

In this way, many enterprises can only be discharged as waste, which not only causes waste of resources, but also causes serious environmental pollution.
