Method for treating livestock and poultry manure by using microbial floras

Abstract

The invention relates to the field of livestock and poultry manure treatment, in particular to a method for treating livestock and poultry manure by using microbial floras. The method comprises the steps that tobacco leftovers and molasses are mixed and then mixed with the livestock and poultry manure to obtain a mixed material B; the microbial floras are added into the mixed material B to be uniformly mixed, and a mixed material C is obtained; after the moisture content of the mixed material C is adjusted, the mixed material C is placed in a fermentation bed for fermentation to finally obtaina fermentation product, wherein the fermentation product can be directly used as farmyard manure or used for preparing an organic fertilizer. According to the method, the microbial floras are adoptedfor fermentation treatment on the livestock and poultry manure, the effects of deodorizing the livestock and poultry manure and killing fly larvae in the whole fermentation process are good, energy is saved, and the environment is protected; the method is simple in technical step and easy to operate, the treatment cost for the livestock and poultry manure in the breeding industry is greatly reduced, and the additional value and utilization rate of the livestock and poultry manure are greatly increased.

Description

technical field [0001] The invention relates to the field of livestock and poultry manure treatment, in particular to a method for treating livestock and poultry manure with microbial flora. Background technique [0002] Livestock and poultry manure is composed of undigested feed nutrients, metabolites in the body, digestive tract mucosa, secretions, intestinal microorganisms and their decomposition products. Livestock and poultry manure is not only a realistic environmental hazard, but also a usable biological resource. Improper use of it will be a serious source of pollution. The role of material energy, waste nutrition and other resources to realize the reuse of waste resources. At present, the comprehensive utilization methods of livestock and poultry manure mainly include the following: 1) Use as fertilizer: Livestock and poultry manure is a high-quality organic fertilizer source for agricultural production. Composting manure and then using it is currently widely used ...

AI Technical Summary

Problems solved by technology

Through biogas fermentation, pathogenic microorganisms in feces can be killed, but there are also certain safety hazards

4) Use deodorant to treat livestock and poultry manure: In order to reduce the pollution of livestock and poultry excrement and its odor, various deodorants can be added to feed or litter, and the treatment cost of this method is relatively high

However, there are still many problems to be solved urgently, such as: feces cleaning process is not perfect, follow-up treatment is difficult; the degree of mechanization is low, and it is difficult to scale up; the structure of treatment equipment is relatively complicated, the project investment is large, the operation cost is high, the smell is large, and the resource utilization is low.
