Abstract

The invention relates to a livestock and poultry excrement treatment method. The method comprises the steps: adjusting the water content of the excrement to 48 to 55 percent, and then uniformly mixing the excrement and a microorganism fermenting agent and inorganic matters according to a mass ratio of (40-55): (4-7): (2-3); and then placing an obtained mixture in a fermenting tank to have anaerobic fermentation, wherein the inorganic matter is a mixture of zinc sulfate, ammonium bicarbonate and calcium chloride or mixture of phosphate rock powder, ammonium bicarbonate and calcium chloride. The method is used for treating livestock and poultry excrement and is fast in fermentation process and pollution-free to the environment, thereby fundamentally solving the environmental pollution problem. The treated livestock and poultry excrement can be directly used as biological organic fertilizer, thereby converting waste into treasure.

Description

technical field [0001] The invention relates to the technical fields of biotechnology and environmental protection, in particular to a method for treating livestock and poultry manure. Background technique [0002] In recent years, with the development of the economy and the improvement of living standards, the demand for livestock and poultry products has continued to increase, and the scale of production has continued to increase. With the expansion of production scale, the pollution caused by the excrement discharge is becoming more and more serious. The pollution of livestock and poultry manure to the environment is mainly the stench, harmful gas and dust carrying pathogenic microorganisms produced by the anaerobic decomposition of manure organic matter. Malodorous and harmful gases mainly include NH 3 、CH 4 、H 2 S, (NH 4 ) 2 S and skatole etc. Studies have shown that 20%-30% of nitrogen in livestock and poultry manure is ammonium nitrogen, which is easily lost by...
