Embodiment 1
[0017] This embodiment provides a method for processing municipal solid waste, which is mainly used for fermenting municipal solid waste. The method is as follows: figure 1 As shown, it specifically includes the following steps:
[0018] Step 1, using the rotten organic matter obtained after sorting from municipal solid waste as raw material;
[0019] Step 2, placing the perishable organic material in a fermentation tank equipped with a mechanical stirring device, and performing negative pressure ventilation in the fermentation tank with a ventilation rate of 0.05-0.2m 3 air / m 3 stacking min, and the materials are stirred by the mechanical stirring device in the fermentation tank, and fermented in an aerobic state for 25 to 30 days;
[0020] Step 3, composting the fermented material for another 25 to 40 days;
[0021] Step 4, performing post-treatment on the decomposed organic matter, and removing impurities such as plastics, sandstone, glass, etc. through screening and air...
