Abstract

The invention relates to the technical field of rural waste treatment and specifically relates to a method for high-temperature efficient aerobic composting of rural organic wastes. The method comprises the following steps: treating rural kitchen wastes in the manner of sorting, oil-water separation and breaking; uniformly mixing the treated rural kitchen wastes with broken animal dung and strawsat a certain ratio, thereby forming a composting material; adding a defined amount of No.1 microbial agent, uniformly mixing and then increasing temperature, controlling temperature and aerating; adding a defined amount of No.2 microbial agent, uniformly mixing and then increasing temperature, controlling temperature and aerating, thereby forming an organic fertilizer. According to the invention,a high-quality fertilizer can be acquired by harmlessly and stably recycling the rural organic wastes within a short period of time. The technology is simple and can be easily popularized.

Description

technical field [0001] The invention relates to the technical field of rural garbage treatment, and more specifically relates to a method for high-temperature and high-efficiency aerobic composting of rural organic garbage. Background technique [0002] With the rapid development of rural economy and society, the acceleration of urbanization process and the gradual establishment of farmers' modern lifestyle, the amount of rural domestic waste is increasing year by year, and the difficulty of disposal is increasing. According to statistics, at present, the amount of garbage generated in my country's rural areas can reach 0.86 kg per person per day, and the annual amount of garbage generated can reach 300 million tons. According to the statistics of the Ministry of Housing and Urban-Rural Development in 2016, only 65% ​​of the administrative villages in the country deal with domestic waste, and 70% of the rural disposal methods are still simple transfer. Moreover, it breeds m...
