Abstract
The invention provides a tubular aeration tank type high-temperature aerobic composting system. The system comprises a fermentation tank and air pipes located at the bottom of the fermentation tank, the air pipes are connected with a tubular micro-hole aerator, and a grating plate covers the upper surface of the tubular micro-hole aerator; water permeable bricks are arranged under the air pipes and the tubular micro-hole aerator, water collection tanks are formed under the water permeable bricks, a turning machine used for uniformly mixing materials in the fermentation tank is arranged on thefermentation tank, and the air pipes are connected with an aeration fan and output oxygen to the tubular micro-hole aerator through the aeration fan. According to the system, the adopted tubular micro-hole aerator can make gas uniformly distributed and improve the oxygen mass transfer efficiency and the fermentation efficiency, through the water permeable bricks and the water collection tanks, moisture in the materials and moisture generated from fermentation can be collected and treated uniformly, and secondary pollution is avoided.
Description
technical field [0001] The invention relates to the technical field of organic fertilizer production, in particular to a tube type aeration tank type high temperature aerobic composting system. Background technique [0002] In recent years, my country's animal husbandry has continued to develop steadily, and the level of large-scale breeding has been significantly improved. While ensuring the supply of meat, eggs and milk, a large amount of livestock and poultry farming waste has not been effectively utilized as a resource, which has become a major problem in rural environmental governance. Therefore, according to the guiding ideology of the Party Central Committee and the State Council, it is necessary to establish a scientific and standardized system with clear rights and responsibilities and strong constraints for the resource utilization of livestock and poultry farming waste, break through the barriers between the livestock and poultry breeding industry and the planting ...
