Abstract

The invention provides a multilayer material (100) for sewage treatment. The multilayer material (100) comprises a loose layer (101), a compact layer (103) and a middle layer (102); aerobic microorganisms are contained in the loose layer (101); anaerobic microorganisms are contained in the compact layer (103); facultative microorganisms are contained in the middle layer (102); the middle layer (102) is arranged between the loose layer (101) and the compact layer (103). The invention aims to provide the multilayer material capable of effectively degrading pollutants and promoting water treatment effect.

Description

technical field [0001] The present invention relates to the field of sewage treatment, and more particularly, to a multi-layer material for sewage treatment. Background technique [0002] In recent years, water pollution has become more and more serious. Residential domestic sewage and industrial production wastewater have been seriously polluted. Discharge into rivers, lakes and other water bodies directly changes the balance of microorganisms in the water body, resulting in a decrease in microorganisms in the water body. The water body is generally polluted beyond the standard. destroy. In the field of water body management, microbial composite bacteria are often used to restore the nutritional structure of water bodies, stabilize or rebuild ecosystems and food chain structures. [0003] In the original water body treatment technology, microbial complex bacteria have the characteristics of large dosage and long domestication time, which cannot achieve the maximum purifica...
