Full-amount treatment device and method for livestock and poultry manure

Abstract

The invention provides a full-amount treatment device and method for livestock and poultry manure, and belongs to the technical field of livestock and poultry manure treatment. The treatment device comprises a high-temperature fermentation bin (1), wherein a plurality of breather pipes (7) are buried at the bottom in the high-temperature fermentation bin (1); the breather pipe (7) is connected with the high-pressure fan (3) through a pipeline; and a plurality of vent holes (7-1) are distributed in the vent pipe (7). The treatment device has the advantages of being high in efficiency, low in cost, large in treatment capacity, capable of achieving continuous fermentation, suitable for cold regions, environmentally friendly and low in carbon. The invention further provides a livestock and poultry excrement treatment method based on the treatment device. The crop straw, the livestock and poultry manure and the fermentation microbial inoculum are used as fermentation materials, a fermentation pile is constructed in the treatment device, high-temperature aerobic fermentation is carried out, the organic fertilizer can be prepared, and the purposes of harmless, reduction and resourceful treatment of the livestock and poultry manure are achieved.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry manure treatment, in particular to a total treatment device and method for livestock and poultry manure. Background technique [0002] At present, the treatment of livestock and poultry manure often adopts solid-liquid separation technology to separate the manure into solid and liquid parts. The solid part is processed by composting fermentation technology to prepare organic fertilizer, while the liquid part is processed by technologies such as biogas fermentation and oxidation pond fermentation. . The prior art has the following defects: 1. There are many processing steps; 2. The processing facility (equipment) (such as solid-liquid separator, anaerobic fermentation facility, equipment, etc.) has high cost and high operating cost; 3. The processed product (such as biogas residue and biogas slurry) will cause potential secondary pollution. The above-mentioned defects limit the appl...

AI Technical Summary

Problems solved by technology

The prior art has the following defects: 1. There are many processing steps; 2. The processing facility (equipment) (such as solid-liquid separator, anaerobic fermentation facility, equipment, etc.) has high cost and high operating cost; 3. The processed product (such as biogas residue, biogas slurry) will cause potential secondary pollution

Above-mentioned defective has limited the application of prior art

Therefore, so far, there is still a lack of effective and practical treatment technologies for livestock and poultry manure.
