Method for fly maggot chitin and microbial sewage treatment and water body ecological restoration

Abstract

The invention relates to a fly maggot chitin and microorganism sewage treatment and water body ecological remediation method and belongs to the technical field of sewage treatment and water remediation. The technical scheme is that fly maggot chitin is mixed with microorganism mixed liquid to prepare fly maggot chitin and microorganism composite liquid, wherein the parts of fly maggot chitin by weight are 1-15 and the parts of microorganism mixed liquid by weight are 85-99; the fly maggot chitin and microorganism composite liquid is added into a water body which needs to be treated or remedied according to a volume ratio of one ten-thousandth to five ten-thousandth to convert pollutants in the water body through flocculation and decomposition; the sewage treatment or water body ecological remediation is completed after 3-7 days. The fly maggot chitin and microorganism sewage treatment and water body ecological remediation method is especially suitable for low-temperature areas, the entire anaerobic, aerobic, flocculation and sterilization process is completed by directly inputting fly maggot chitin composite liquid, and the problems that the growth speed of aerobic bacteria and anaerobic bacteria is slow and the sewage treatment effect is poor at low temperature when the conventional sewage treatment process is adopted are solved; large-sized equipment for anaerobic and aerobic bacteria growth does not need to be installed, the purifying effect exceeds the industrial standard, the operating cost is low and the cost is almost zero.

Description

technical field [0001] The invention relates to a method for fly maggot chitin and microbial sewage treatment and water body ecological restoration, and belongs to the technical field of sewage treatment and water body restoration. Background technique [0002] Sewage treatment and water body restoration are the focus of environmental protection work. Generally, chemical agents are used for treatment, which is likely to cause secondary pollution. It requires the construction of treatment facilities, which requires a large investment and poor effect; especially in northern my country, aerobic bacteria in conventional sewage treatment processes at low temperatures Anaerobic bacteria grow slowly and the sewage treatment effect is poor. BACKGROUND OF THE INVENTION The use of chitin for sewage treatment mainly uses chitin for flocculation. However, due to the relatively low molecular weight of chitin, the flocculation effect is not ideal. Fly maggot chitin is a completely differe...
