Heterotopic fermentation bed livestock and poultry breeding manure treatment system and its application

Abstract

The invention discloses an ectopic fermentation bed livestock breeding excrement treatment system and an application thereof. The ectopic fermentation bed livestock breeding excrement treatment system comprises at least one breeding house, a dirt collecting tank, a first cutting pump and a fermenting house, wherein the fermenting house comprises a plurality of ectopic fermentation beds, a spray tank and a spray device; the bottom of the breeding house communicates with the dirt collecting tank; one end of the first cutting pump communicates with the dirt collecting tank, and the other end of the first cutting pump is connected to the spray tank; the spray tank is positioned among the four ectopic fermentation beds; the spray device comprises a second cutting pump and a plurality of spray pipes; one end of the second cutting pump communicates with the spray tank, and the other end of the second cutting pump separately communicates with the plurality of the spray pipes; and each spray pipe is correspondingly arranged above one ectopic fermentation bed transversely, and a plurality of water spray holes are formed in the side walls of the spray pipes. According to the ectopic fermentation bed livestock breeding excrement treatment system, the excrement generated by pig breeding is mixed with padding for fermenting, so that the odor and toxin of the pig excrement are eliminated, the excrement treatment capacity is improved, the fermentation operation efficiency is improved, the service life of the padding is prolonged, and the fermentation quality of an organic fertilizer is improved.

Description

technical field [0001] The invention specifically relates to a system for treating manure from livestock and poultry breeding in an ectopic fermentation bed and its application. Background technique [0002] The livestock and poultry breeding industry is the pillar industry of my country's agriculture. It has developed rapidly, and the scale of breeding has gradually expanded, and the amount of manure produced has also increased significantly. At the same time, a considerable number of farms have incomplete environmental protection facilities, employees have weak awareness of environmental protection, the country's governance by law is insufficient, and the impact of livestock and poultry breeding on the surrounding environment is very severe. Traditional breeding pollution control mainly adopts the following modes: [0003] (1) Dry excrement cleaning technology: simple equipment, low energy consumption, and low investment, but heavy labor, low production efficiency, and pr...
