Problems solved by technology

Among them, the dynamic non-reactor composting is represented by the pile-type turning and throwing composting process, which mainly relies on turning and throwing machinery to realize the oxygen supply and fermentation of the compost. It has the characteristics of simple, easy to operate, and large processing capacity, but it is often accompanied by nutrient leaching. Environmental pollution problems such as the large spread of odor, the spread of pathogenic bacteria, and the continuous breeding of mosquitoes and flies are important constraints that affect the development of dynamic non-reactor composting
The dynamic reactor type composting technology mainly relies on the automatic mechanical system to realize the processes of material feeding, stirring, ventilation and oxygen supply, and material discharging. Large, high operating costs, difficult to promote

Abstract

The invention relates to a nano membrane aerobic composting device for livestock manure. The device comprises a host, a supply duct, an anti-seepage layer, a composite nano membrane, a sealing device,a multi-point temperature sensor, a moisture content sensor and an oxygen concentration sensor. The device is outstanding in environmental protection, involves composting between open and closed aerobic composting, and is suitable for treating the livestock manure in situ or near a farm to avoid secondary pollution caused by transfer; the composite nano membrane effectively blocks the emission ofharmful substances such as odor, pathogenic bacteria and aerosol, the environmental condition in the membrane is efficiently controlled to form an internal environment suitable for microbial life metabolism, and the composting fermentation process is effectively controlled through a feedback regulation mechanism, so that the livestock manure is composted more thoroughly and the cost is lower. Thedevice has simple requirements for sites, does not need to build a factory building, can be used in the open air, is easy to operate, automatic in operation and unmanned, and can be monitored and controlled remotely to save labor and time.

Description

【Technical field】 [0001] The invention belongs to the technical field of harmless treatment and resource utilization of livestock and poultry manure. More specifically, the invention relates to a nano-film aerobic composting device for livestock and poultry manure. 【Background technique】 [0002] With the rapid development of my country's agriculture, medicine, food and other industries, the production of organic solid waste such as livestock and poultry manure, crop straw, distiller's grains, Chinese herbal medicine residue, and edible fungus residue has increased year by year, causing serious environmental pollution. Taking livestock and poultry farming as an example, it improves people's quality of life, but due to the lack of low-input, high-efficiency environmental protection treatment technology, a large amount of livestock and poultry manure without harmless treatment enters the soil through runoff and leaching. Water bodies have caused serious environmental pollutio...
