Embodiment Construction

[0020] figure 1 It is a process flow chart of the manure treatment system and method of the sheep farm. Fresh manure is separated into liquid manure and solid manure by a manure solid-liquid separation device. The solid manure is transported by cart or ropeway to the manure pretreatment shed for dehydration and drying, and then sent to the manure fermentation shed for composting fermentation. After the fermentation process is completed, it is sent to the factory for processing into organic fertilizer. The liquid manure is first concentrated in the regulating tank, and then transported to the biogas tank for fermentation. The fermented biogas slurry farmers can irrigate the nearby fields for fertilization, and the biogas provides the living and production needs of the farm personnel.

[0021] figure 2 It is a manure solid-liquid separation device in the manure treatment system and method of a sheep farm. The fresh manure enters from the manure inlet (1), the liquid manure fal...

Abstract

The invention discloses a system and a method for treating manure in a sheep culturing farm. The system comprises a manure solid-liquid separator, an adjustment tank, a manure pre-treatment shed, a manure fermentation shed, a liquid manure conveying pipe and a methane tank. The method comprises the following steps of carrying out a solid-liquid separation process on fresh manure, transferring the solid manure to a composting fermentation field by manual or mechanical conveying, carrying out composting fermentation, transferring the fermentation products into an organic fertilizer processing factory, adding some components into the fermentation products to obtain a commercial organic fertilizer, transferring the liquid manure to the methane tank by a special pipe system, and carrying out fermentation, wherein the produced biogas slurry is used for fertilization in the neighbourhood by peasants and the produced biogas is used for the living of workers and the production in the sheep culturing farm.

Description

technical field [0001] The invention belongs to the field of agricultural environmental protection, and relates to a sheep farm excrement treatment system and method, in particular, the sheep excrement can be turned into treasure without causing pollution to the surrounding environment. Background technique [0002] In recent years, with the rapid development of my country's large-scale sheep breeding industry, a large amount of manure and sewage produced by sheep breeding has also become an important source of pollution. The manure, waste and organic wastewater produced by large-scale sheep farms are directly discharged without treatment and utilization, which will cause pollution to farmland. Especially in the periphery of big cities, the pollution of manure and urine from large-scale aquaculture has caused the deterioration of the surrounding environment of the city, and the serious pollution of surface water and groundwater has affected the health of humans and animals a...
