A comprehensive ecological utilization system for poultry and livestock manure

Abstract

The invention relates to the technical field of agricultural ecology, in particular to an ecological comprehensive utilization system for poultry and livestock breeding manure. The system includes: movable or conveniently disassembled poultry breeding houses, dry-wet separation equipment, anaerobic fermentation equipment, discharge dehydration equipment, biogas power generation equipment, and vegetable and fruit tree planting areas; the dry-wet separation device separates feces Separation into dry manure and biogas slurry; the biogas slurry is used for anaerobic fermentation, and the dry manure is used for composting; the produced fertilizer is transported to the vegetable and fruit tree planting areas for utilization. The system provided by the invention has a high degree of automation, not only reduces operating input and operating costs, but also improves resource utilization efficiency of agricultural and animal husbandry waste. The application of this system can establish a livestock breeding park with a closed energy structure, realize a circular agricultural industrial chain, utilize rural straw gasification clean energy, and solve the problem of comprehensive utilization of livestock breeding waste in rural areas or enterprises. It can truly be implemented and operated normally. , truly turning waste into treasure. Make due contributions to "beautiful countryside, rich farmers, 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
