Description

technical field

[0001] The invention belongs to the technical field of ecological environment, and specifically relates to a method and system for treating human excrement. Background technique

[0002] Human excrement, excrement and urine are equivalent to farm manure like livestock and poultry manure. Compared with chemical fertilizers, human excrement has the advantages of wide sources, complete nutrients, long-lasting fertilizer effect, ability to improve soil and low cost, and can be used as top dressing and base fertilizer. In the prior art, when human excrement and urine are processed, since human excrement and urine contain a large number of germs, insect eggs and other harmful substances, they will pollute soil, air, water sources and crops, and then spread diseases, causing serious harm to human health. , so they all need to be used after high-temperature composting.

[0003] Human excrement has been used for thousands of years in our country's farming civilizati...
