Method of treating feces in breeding industry

Abstract

The invention relates to a method of treating feces in breeding industry, in particular relates to a method and a device for treating livestock feces in a breeding house underground to produce biogas and an organic fertilizer and belongs to the technology and equipment needed by resource and environment field. The device comprises a breeding house, a breeding house equipment room, a breeding house aisle, a feces gutter, a feces output pipe, a precipitation and impurity removal system, a solid-liquid separation system, a biogas digester system, a biogas temperature improvement and insulation system, a biogas reflux house flushing and crust breaking system and a biogas storage and purification system, wherein the breeding house, the breeding house equipment room, the breeding house aisle, the feces gutter, the feces output pipe, the precipitation and impurity removal system, the solid-liquid separation system, the biogas digester system, the biogas temperature improvement and insulation system, the biogas reflux house flushing and crust breaking system and the biogas storage and purification system are connected with one another. According to the method disclosed by the invention, the main treatment equipment is mounted in the breeding house underground, is small in occupied area, high in resource comprehensive utilization ratio and remarkable in economical and environmentally friendly benefits and is capable of purifying the biogas and producing the organic fertilizer.

Description

technical field [0001] The invention relates to a method for treating feces in aquaculture, in particular to a method and device for underground processing of livestock and poultry manure in a breeding pen to produce biogas and organic fertilizer, which belongs to the required technology and equipment in the field of resources and environment. Background technique [0002] my country has a vast territory, a large population, and a huge demand for meat, eggs, and milk. It is a big country for livestock and poultry farming. On the one hand, meat, eggs, and milk are people's daily necessities, and the breeding industry needs to be vigorously developed to meet social needs. On the other hand, a large amount of livestock and poultry manure Without treatment, it is discharged without authorization, which seriously pollutes the living environment and groundwater sources. The pollution of manure and odor poses a huge threat to the healthy and sustainable development of agriculture and...

[0002] my country has a vast territory, a large population, and a huge demand for meat, eggs, and milk. It is a big country for livestock and poultry farming. On the one hand, meat, eggs, and milk are people's daily necessities, and the breeding industry needs to be vigorously developed to meet social needs. On the other hand, a large amount of livestock and poultry manure Without treatment, it is discharged without authorization, which seriously pollutes the living environment and groundwater sources. The pollution of manure and odor poses a huge threat to the healthy and sustainable development of agriculture and aquaculture.

The existing methods of manure treatment have the problem of not fully realizing that manure is also a resource, and not making full use of it and transforming it well; secondly, the treatment method of manure is single, there is no comprehensive treatment, the treatment efficiency is low, and the equipment occupies an area Large area, high operation and maintenance costs, affecting large-scale promotion and use
