Abstract

An organic solid waste water regulation high-temperature aerobic composting device and a method thereof relate to an organic solid waste composting device and a method thereof. The invention settles the problem of affecting the quality of the composting product, which is caused by the vertical maldistribution of the moisture content of the composted object in the warehouse type forced ventilation composting process. The prior mode for adjusting the moisture content has the defects of complicated device and high cost. The conical warehouse top of the device according to the invention is installed on the upper end face of the fermentation warehouse. An annular water collecting groove is provided in the fermentation warehouse. A plurality of water distributors are provided in the fermentation warehouse. The upper end of the water inlet pipe is communicated with the annular water collecting groove, and the lower end of the water outlet pipe is communicated with a water distributing pipe. The method of the invention comprises the following steps: mixing the organic solid waste with the fermentation conditioner, executing intermittent ventilation, executing water distribution for the composted object through the water distributors in the fermentation process, in the 12-th to 15-th day of fermentation, reducing the temperature of the composted object to less than 40 DEG C, and completing the fermentation process of the composted object. The organic solid waste water regulation high-temperature aerobic composting device and the method according to the invention have the advantages of: uniform water content of composted object, high quality of the composted product and low cost.

Description

technical field [0001] The invention relates to an organic solid waste composting device and method. Background technique [0002] With the rapid development of economy and society, various organic solid wastes, such as domestic garbage, food waste, poultry manure and sewage plant sludge, are also increasing rapidly. Because these organic solid wastes contain a large amount of easily degradable and corrupt substances, if they cannot be disposed of quickly and properly, the organic matter will easily rot and deteriorate, resulting in odor, breeding of mosquitoes and flies, spreading of germs, and seriously affecting the living environment of the surrounding residents. [0003] As a "three modernizations" treatment technology that combines reduction, resource utilization, and harmlessness, composting has been widely used in the treatment of various organic solid wastes. Compared with traditional natural ventilation composting, closed forced ventilation composting can not only...
