[0021] The processing of the present invention is mixed-collected domestic garbage, and the processing capacity is 300t / d. The initial moisture content of garbage is 71.6%, the mass percentage of kitchen waste and peel garbage is 69%, paper is 16%, plastic is 10%, and other 5%; the organic matter percentage of dry matter is 88%.
[0022] The storage density of domestic waste is 550kg / m 3 , The treatment period is 16 days. The trough type composting reactor used for processing has a width of 4m, a garbage stacking height of 1.5m, and a total length of 1440m. The trough reactor is divided into 16 parallel lines, each with a length of 90m, which can be processed The amount of garbage in a day is used in turn to meet the requirements of continuous treatment.
[0023] The trough-type composting reactor is equipped with a stack turning device, and a ventilation channel is laid at the bottom and used for leachate collection. One end of the ventilation channel is connected with a leachate ...
