Combined treatment method for livestock and poultry excrement through microbial preparations and insects

Abstract

The invention discloses a combined treatment method for livestock and poultry excrement through microbial preparations and insects. The method includes the following steps that the livestock and poultry excrement and conditioners are evenly mixed, the microbial preparations are inoculated, then the livestock and poultry excrement are composted and fermented, after primary composting, excrement compost is spread out and aired, and saprophytic insect eggs are inoculated for cultivation; after being mature, the insects are collected to feed bred animals, or the insects are dried, smashed and manufactured into a feeding protein source for use; then post-maturation is performed on the remaining excrement, and then the excrement is dried and smashed to be used as bio-organic fertilizers. The saprophytic insect eggs are inoculated into the excrement after fermentation, by the utilization of efficient transformation of the insects, the novel feeding protein source is developed, and the remaining excrement can be used as the bio-organic fertilizers after post-maturation processing. In this way, the problems that the livestock and poultry excrement pollutes the environments and stinks are solved, besides, insect protein can be harvested, the bio-organic fertilizers are produced, and the economic utilization value of fermentation treatment products of the livestock and poultry excrement is improved.

Description

technical field [0001] The invention belongs to the field of harmless and resourceful utilization of livestock and poultry breeding waste, and in particular relates to a method for jointly treating livestock and poultry excrement by utilizing microbial preparations and insects. Background technique [0002] In recent years, with the intensive and large-scale development of animal husbandry production, the breeding industry has produced a large amount of livestock and poultry manure, which not only pollutes the living environment of livestock and poultry animals, but also easily causes the occurrence and epidemic of diseases, and the harmful gas emitted by manure is also harmful. polluted the environment. [0003] According to incomplete statistics, the annual production of livestock and poultry manure in my country has reached more than 3 billion tons. With the further development of my country's livestock and poultry breeding industry, this figure is still rising. A large ...

Problems solved by technology

[0004] In order to solve the problem of livestock and poultry manure treatment, a large amount of research work has been carried out at home and abroad, but they mainly focus on the preparation of fertilizers, such as fermenting manure by bacterial agents or treating manure by fly maggots, etc., although these methods can play a certain role. effect, but the treatment efficiency is low, and the problem of odor pollution in the fermentation process is relatively serious, and the purpose of harmless treatment and resource utilization of livestock and poultry manure has not been achieved
