Description

Technical Field

[0001] The utility model relates to the technical field of waste treatment, in particular to a small agricultural waste fertilizer composting box. Background Art

[0002] Aerobic composting technology is mainly used to treat high-concentration organic waste, such as agricultural waste, food waste, livestock and poultry manure, and sludge. Compared with anaerobic fermentation, aerobic composting has two advantages in treating organic matter. One is that it can degrade organic matter more thoroughly, and the other is that the treatment time is shorter than anaerobic fermentation. Therefore, aerobic composting is widely used in the treatment of organic waste.

[0003] Small family farms, agricultural tourism bases and other units will generate a certain amount of agricultural solid waste, but the treatment method is relatively simple. Most of them are transported to landfills by municipal garbage trucks for disposal, and true resource utilization, reduction and harmless utilization are not achieved. At present, the composting process mainly relies on turning the pile and stirring to increase the oxygen intake. The gas and dust generated by this process are not friendly to the staff, and the composting efficiency is greatly affected. Utility Model Content
