Harmless treatment method for livestock manure

Abstract

The invention provides a method for innocuously processing livestock and poultry manure. The method is to make the livestock and poultry manure, various auxiliary materials and zymogen powder reach high temperature in short period through automatically depositing and fermenting so as to completely kill harmful pathogenicbacterium, parasitic ova, weed seeds and the like in leavening and eliminate malodor, so that an organic matter containing nitrogen and phosphor in the leavening can be quickly converted into organic fertilizer without bacteria, plant diseases and insect pests or weed seeds, is rich in organic matters and has high readily available nutrient content. The method has the characteristics of simple and convenient operation, low cost, strong innocuousness of the produced organicfertilizer, good leavening effect and the like, can convert manure of a farm into good feed resources and fertilizer resources so as to effectively improve the environment of a production location and a manufacturing location, protect ecological environment of city and countryside, and improve economic benefit. The technology can completely kill harmful bacterium, plant diseases and insect pests and weed seeds, reduce energy consumption and malodor emission with short treatment time, and reduce nutrient loss.

Description

technical field [0001] The invention belongs to excrement treatment, and in particular relates to a technology suitable for livestock and poultry excrement treatment in farms---a harmless treatment method for livestock and poultry excrement.
