Ecological comprehensive utilization system for livestock breeding feces

Abstract

The invention relates to the technical field of agriculture ecology, in particular to an ecological comprehensive utilization system for livestock breeding feces. The system comprises a movable of detachable livestock breeding shed, a dry and wet separation device, an anaerobic fermentation device, a discharging and dewatering device, a biogas power generation device and a vegetable and fruit treeplanting area, the feces is separated into day feces and biogas slurry by the dry and wet separation device, the biogas slurry is used for anaerobic fermentation, the day feces is used for compost, and generated manure is transported to the vegetable and fruit tree planting area and utilized. The system is high in automation degree, operating investment and running cost are reduced, the resourceutilization efficiency of agricultural and pastoral waste is improved, a livestock breeding park with a closed energy structure can be built by the system, a circular agriculture industry chain is achieved, rural straw gasification clean energy is utilized, comprehensive utilization of village or enterprise livestock breeding waste is achieved, the system can be truly implemented and normally run,waste materials are truly changed into things of value, and due contribution is made to 'beautiful villages, wealthy framers and strong agriculture'.

Description

technical field [0001] The invention relates to the technical field of agricultural ecology, in particular to an ecological comprehensive utilization system for poultry and livestock breeding manure. Background technique [0002] my country is one of the first countries in the world to carry out poultry breeding. Since the 1980s, my country's poultry breeding industry has changed from small-scale, decentralized operations in the past, mainly distributed in agricultural areas, to large-scale, centralized operations. , and develop to the outskirts of the city. This change in production mode has greatly promoted the development of my country's animal husbandry production. However, with the rapid development of large-scale farming, huge poultry and livestock breeding has brought a huge amount of poultry manure, and the environmental pollution of poultry and livestock manure agents has become more and more serious. At present, the annual output of poultry manure in many areas ha...

AI Technical Summary

Problems solved by technology

The layout of the farms is scattered, with many points and wide areas, and the waste disposal is not good, which causes serious pollution in the countryside. While developing the rural economy, it damages the environment and destroys the construction of a beautiful countryside.

[0010] In addition, in the existing technologies related to the harmless treatment and recycling of poultry and livestock, there are generally problems of simple manure cleaning methods and lack of effective treatment of sewage and manure

Moreover, the digestive flora and fermentation conditions are unreasonable, and the gas production potential and quality of the system are not high
