Membrane coverage aerobic composting system suitable for intermittent feeding and using method thereof

Abstract

The invention relates to a membrane coverage aerobic composting system suitable for intermittent feeding and a using method thereof. The membrane coverage aerobic composting system comprises a membrane coverage unit, a composting groove unit, a composting parameter collection and ventilation control unit and a percolate recycling unit. The system is suitable for large-scale organic waste treatmententerprises, mechanisms such as small-scale treatment centers which frequently conduct intermittent feeding and composting, or enterprises such as livestock and poultry breeding enterprises. Meanwhile, the invention provides a biological heat air heating system. The biological heat air heating system is based on the microbial fermentation principle and can be connected with an air blower and thelike of the membrane coverage composting system to achieve ventilation and heating in cold regions or in cold seasons.

Description

technical field [0001] The invention belongs to the technical field of resource utilization of organic waste, and relates to a film-covered tank type aerobic composting system and a use method thereof. Background technique [0002] Livestock and poultry breeding, agricultural production and human life will produce a large amount of organic waste such as straw and livestock manure. According to statistics, Jilin Province alone produces about 90 million tons of livestock and poultry manure, 50 million tons of corn stalks and hundreds of millions of tons of domestic waste every year. Affected by lifestyles and farming patterns, these resources are completely in a state of high consumption, high pollution, and low output. A considerable part of organic waste such as livestock and poultry manure and crop straw is disposed of or burned, and has not been rationally developed. Utilization not only wastes a lot of resources, but also creates continuous pollution pressure on the agri...

Problems solved by technology

However, this technology has the following disadvantages: (1) the covering film is often rubbed against the ground, which is easy to be damaged and aged; (2) the surface of the film is smooth, and it is troublesome to recycle the covering or roll film; (3) it needs a lot of heavy objects to press the film to fix the wind, It is easy to freeze on the ground in winter; (4) produces a large amount of leachate, and the site needs to be replaced frequently; (5) consumes a lot of energy and cannot be used in cold climate areas; (6) cannot meet the frequent operation requirements for daily processing; (7) ) requires a large amount of wheat bran, rice husk or fungus chaff as auxiliary materials, which increases the processing cost

[0014] Patent CN 105036838 B also discloses an energy-saving, environmentally friendly and efficient aerobic composting system, but it also performs film-covered composting on the ground; it has the same defects as the above-mentioned CN201811120473.X patent
