Abstract

The invention discloses a resource utilization and comprehensive treatment process for sewage and manure generated during cultivation. The process comprises the following steps: collecting sewage and manure as basic raw materials; delivering the basic raw materials into a fermentation apparatus for manure fermentation; and sending a product of manure fermentation to a feeding farm for feeding of earthworms and collecting the earthworms and earthworm manure; wherein manure fermentation comprises manure inactivation and fermentation cultivation, manure inactivation and fermentation cultivation are continuously carried out in the same fermentation apparatus, and the fermentation apparatus realizes overturning and stirring of the manure generated during cultivation in the processes of manure inactivation and fermentation cultivation and discharging of the manure after completion of fermentation cultivation through rotation of the fermentation apparatus. The process provided by the invention has the advantages of simple steps, strong operability, a high resource utilization rate, a small land occupation area, a short period of consumed time, a wide application scope, good economic benefits, greenness, environment friendliness and the like.

Description

technical field

[0001] The invention relates to a comprehensive treatment method for resource utilization of sewage and excrement, in particular to a comprehensive treatment process for resource utilization of breeding sewage and excrement. Background technique

[0002] In recent years, the mode of raising pigs has changed from rural free-range breeding to intensive farming, and the food of pigs has also changed from the leftover hogwash to unified feed. Following this, the amount of pig manure is huge, and the excrement is harmful to the environment. pollution is becoming increasingly serious. The toxic and harmful substances in livestock and poultry manure are seriously beyond the capacity of the environment. If they are not treated harmlessly, it will not only cause groundwater pollution and microbial content exceeding the standard, but also pollute the air, making ammonia, sulfur dioxide and other harmful gases in the atmosphere At the same time, livestock and poultry m...
