Abstract

The invention discloses a novel process for processing chicken manure through aerobic fermentation. A high-efficiency, green chicken manure fermented bio-organic fertilizer is developed by using a rapid fermentation process of mixed bacteria solids. The compound microbial agents include bacillus coagulans, bacillus licheniformis, thermophilic heterotrophic ammonia-oxidizing bacteria, aspergillus niger and the like. The process adopts multi-bacterium mixed fermentation, through the combination of different metabolic abilities, the complex metabolic effects that are difficult to complete by a single strain can be completed, through the synergistic fermentation between microorganisms, the effective conversion of chicken manure is realized, the health indexes meet the national standards, and the product maturity and growth promotion indexes are significantly improved. The fermentation process is simple and efficient, has good deodorizing and sterilizing effect, has low production cost, andis easy for industrial large-scale production.

Description

technical field [0001] The invention relates to a new process for treating chicken manure by aerobic fermentation, in particular to a process for preparing bio-organic fertilizer with good growth-promoting and production-increasing effects by using various probiotics to collaboratively ferment chicken manure and straw, and belongs to the field of bioengineering . Background technique [0002] With the development of modern animal husbandry, the scale and intensification of poultry farms continue to increase, and the feces produced by large poultry farms seriously pollute the environment. The State Environmental Protection Administration’s 2002 survey on the pollution of large-scale livestock and poultry farming shows that the annual livestock and poultry manure volume in China is about 1.9 billion tons, of which COD (chemical oxygen demand) emissions have reached 71.18 million tons, and the livestock and poultry manure output Both COD and COD emissions far exceed the sum of...
