Excrement fermentation shed deodorizing method and system

Abstract

The invention provides an excrement fermentation shed deodorizing method. The excrement fermentation shed deodorizing method comprises the following steps: collecting and diluting odor in an excrementfermentation shed, circularly spraying microorganisms for deodorization, performing the deodorization by virtue of a chemical deodorizing agent, and then discharging the odor. The invention also provides an excrement fermentation shed deodorizing system. The excrement fermentation shed deodorizing system comprises a first spraying room adjacent to the excrement fermentation shed, and a second spraying room communicated with the first spraying room, wherein the first spraying room is communicated with the excrement fermentation shed by virtue of a fan; spraying pipes are distributed in the first spraying room, and circulating water with microorganisms is introduced into the spraying pipes to be sprayed; a plurality of spraying pipes are arranged in the second spraying room, and a chemicaldeodorizing agent is introduced into the spraying pipes to be sprayed; and the second spraying room is provided with an exhaust port for exhausting the treated gas. The deodorizing method of the invention effectively treats the odor generated by the excrement fermentation shed by virtue of microbial degradation, chemical treatment and photocatalyst decomposition of the odor; and the deodorizing system is low in construction investment and low in operation cost.

Description

technical field [0001] The invention belongs to the technical field of deodorization in a feces fermentation shed, and in particular relates to a deodorization method for a feces fermentation shed, and also relates to a deodorization system for a feces fermentation shed. Background technique [0002] Composting is currently the mainstream method of livestock and poultry manure treatment at home and abroad, and it is also the most mature technology. The ectopic fermentation bed technology uses litter to keep livestock and poultry manure in the high-temperature fermentation period of composting, and maximizes the use of microorganisms to degrade and transform chickens. manure. Feces will produce harmful gases during the process of being degraded by microorganisms, but due to differences in the metabolic processes of different microorganisms, their final metabolites are also slightly different. General aerobic bacteria produce NH 3 , CO 2 、H 2 O, while anaerobic bacteria pr...

Problems solved by technology

[0008] In view of this, in view of the above problems, the first object of the present invention is to provide a method for deodorizing the excrement fermentation shed, which can solve the problem that the water vapor in the fermentation shed cannot be lost in time, and at the same time can eliminate the odor produced by the excrement fermentation shed. Effective treatment, after treatment can meet the requirements of direct discharge
