Abstract

The invention discloses a harmless pig manure treatment method. The harmless pig manure treatment method comprises the steps of mixing pig manure, corn straw and rice straw powder according to a certain mass ratio to obtain a mixed material; controlling the moisture content of the mixed material to be 60%-70% according to a mass ratio to obtain an initial material, and adding microbial flora and acomposting primer according to a certain ratio, wherein the microbial flora comprises one or more of bacillus, actinomycetes, yeast and filamentous fungi; and conducting aerobic fermentation on the initial material, which is subjected to composting, under a condition of heat preservation until a C/N value of the initial material decreases to 12-18 and the moisture content is 24%-30%. Rice straw and the fresh pig manure are used as raw materials, an aerobic composting technology is adopted for conducting harmless treatment on the pig manure, through the microbial flora, a composting system isheated fast, and the harmless pig manure treatment method benefits shortening of composting time, reduction of the content of refractory substances in organic materials and improvement of the composting quality.

Description

technical field [0001] The invention mainly relates to the technical field of harmless pig manure, in particular to a method and device for harmless treatment of pig manure. Background technique [0002] my country is the country with the largest output of crop straw and pig manure in the world. In the past 30 years, due to changes in the rural energy structure, there has been a large surplus of crop straw, and the phenomenon of burning straw has been repeatedly banned, which wastes resources and pollutes the environment. At the same time, The natural discharge of pig manure will cause high pathogenic bacteria in the manure to pollute surface water and groundwater, emit a foul smell, and pollute the environment. [0003] Composting is the most effective method for the harmlessness, reduction and resource utilization of straw and livestock and poultry manure. It can not only kill pathogenic microorganisms in manure, reduce the volume and quality of agricultural waste stockpile...
