Problems solved by technology

[0006] In view of this, the present invention provides a chicken manure organic fertilizer production method which integrates chicken manure aeration and oxygenation and ectopic fermentation bed composting, which not only overcomes the insufficient ventilation and oxygen supply caused by the high humidity of chicken manure, especially The chicken manure at the bottom and corners of the fermentation bed is incompletely fermented and decomposed, and even has the defect of "dead bed". By adding an aeration device, the effect of chicken manure fermentation and decompression is improved, the time for chicken manure fermentation and decomposition is shortened, and the amount of chicken manure in the chicken manure is reduced. Nitrogen loss and organic fertilizer production costs

Abstract

The invention discloses a chicken manure fermentation composting method based on diaphragm type aeration treatment. The chicken manure fermentation composting method comprises the following steps: constructing an aeration type fermentation bed, designing aeration pressure relief process, filling a fermentation material, adding a fermentation microbial inoculum, and aerating and introducing oxygen.According to the invention, the defects of incomplete fermentation and decomposition of the chicken manure, and even dead bed caused by over-high humidity of the chicken manure and insufficient ventilation and oxygen supply, especially at the bottom layer and corners of the fermentation bed, are avoided; and aeration device are adopted to improve chicken manure fermentation and decomposition effects.

Description

technical field [0001] The invention relates to the technical field of composting fermentation, in particular to a method for fermenting and composting chicken manure based on membrane type aeration treatment. Background technique [0002] While my country's chicken industry is developing intensively and on a large scale, the contradiction between it and environmental pollution is becoming increasingly prominent. A large amount of chicken manure produced by farms every year will cause serious pollution to the ecological environment if it is not disposed of in a timely and effective manner. [0003] At present, the most scientific and economical treatment mode of chicken manure recognized by the industry is to produce organic fertilizer and return it to the nearby field for consumption and utilization. There are two main ways to produce organic fertilizer from chicken manure: one is fermented by bioreactor; the other is aerobic fermentation compost. Aerobic fermentation com...
