Establishing method of a controllable breeding fermentation bed with air cushion layer and fermentation bed

Abstract

The invention belongs to the field of livestock breeding technology, facilities and equipment, and particularly relates to an establishing method of a controllable breeding fermentation bed with an air cushion layer and a fermentation bed. The establishing method is characterized in that a complete-area air cushion layer is arranged on the lower part of a fermentation cushion layer or a partial-area air cushion layer is arranged in a livestock centralized excretion area, natural circulation of air is maintained inside the air cushion layer or a mechanical air supply system is arranged inside the air cushion layer, the air cushion layer sequentially consists of an anti-seepage terrace layer (6), an elevated layer (5), a net layer (4) and a gradation material layer (3) from bottom to top, the bottom of the elevated layer (5) is provided with a ventilation pipe (7), or the air cushion layer sequentially consists of an anti-seepage terrace layer (6) and a gradation material layer (3) from bottom to top, the bottom of the gradation material layer (3) is provided with a horizontal open pore ventilation pipe (18), and the ventilation pipe (7) and the open pore ventilation pipe (18) are connected with a fan (10) of the mechanical air supply system. Due to the adoption of the establishing method and the fermentation bed, the microorganism waste digestion atmosphere in the livestock fermentation bed can be controlled in an omnibearing manner, the fermentation bed can stay at an appropriate aerobic state, the adaptability of the fermentation bed to the breeding condition and the breeding load can be enhanced, the working state of the fermentation bed can be optimized, and the service life of the fermentation bed can be prolonged.

Description

technical field [0001] The invention belongs to the field of livestock and poultry breeding technology, facilities and equipment, and in particular relates to a method for establishing a controllable breeding fermentation bed with an air cushion layer and the fermentation bed. Background technique [0002] Modern large-scale livestock and poultry breeding, while improving productivity, also brings a large amount of livestock and poultry manure that is difficult to handle, resulting in serious environmental pollution; at present, the annual production of livestock and poultry manure in China has reached 1.9 billion tons, exceeding the industrial solid The amount of waste discharge is more than twice; the existing various livestock and poultry manure treatment technologies mainly adopt the comprehensive utilization method, and realize the elimination of manure through the use of agricultural manure, and some biogas slurry adopts the method of treatment and discharge. Due to th...
