Three-dimensional breeding excrement and biogas slurry recycling system and three-dimensional breeding room

Abstract

The invention discloses a three-dimensional breeding excrement and biogas slurry recycling system and a three-dimensional breeding room, solves the problem that animal excrement in building breeding in the prior art is not well treated, and has the beneficial effects that the excrement is effectively treated, and solid excrement and biogas slurry are treated respectively and recycled. According to the specific scheme, the three-dimensional breeding excrement and biogas slurry recycling system comprises a collecting mechanism and a fermentation and solid-liquid separation mechanism; the collecting mechanism comprises a water collecting pond and a liquid manure pit, an excrement leaking plate layer is installed on the surface of a floor of a breeding building, the liquid manure pit is supported by the floor of the breeding building so as to discharge excrement generated by the breeding building to the liquid manure pit, the liquid manure pit is filled with liquid, and the liquid manure pit is connected with the water collecting pond; and the fermentation and solid-liquid separation mechanism comprises a biogas fermentation unit and a solid-liquid separation mechanism, the biogas fermentation unit is connected with the water collecting pond, the solid-liquid separation mechanism is connected with the biogas fermentation unit, and an outlet of the solid-liquid separation mechanism is separately connected with a biogas slurry storage tank and a solid manure pit.

Description

technical field [0001] The invention relates to the technical field of recycling of breeding manure, in particular to a three-dimensional breeding manure and biogas slurry recycling system and a three-dimensional breeding house. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In recent years, the aquaculture industry has flourished. However, the contradiction of the shortage of breeding land has gradually become prominent. Based on this contradiction, people have turned their attention from the traditional planar breeding layout to three-dimensional building breeding, such as building pig breeding, which has many advantages. First of all, it saves land and facilitates site selection. Building breeding can double the number of breeding per unit of breeding land area, effectively improving the land utilization rate. At the same time, the...

Problems solved by technology

[0004] However, a big problem in building farming is how to deal with livestock and poultry manure. The inventors found that the processing method in the prior art needs to manually transport manure, which does not make full use of the characteristics of buildings, and it is troublesome to deal with and transport manure; and after treatment The feces can also be fully utilized; these two problems have plagued farmers and relevant local government departments, and have also become a serious obstacle to the large-scale development of building farming
