Abstract

The invention provides an immobilized microorganism structural body and a preparation method thereof. The method comprises the following steps: S1, taking municipal biomass waste as a raw material, and chemically activating the raw material; S2, carbonizing the chemically activated product at a low temperature to obtain biomass-based biochar; S3, mixing an embedding agent with the biomass-based biochar, wherein the embedding agent comprises a biodegradable material; S4, adding an oxygenation agent, microorganisms with a degradation effect for black and smelly river channels and growth factor to the mixture obtained in step S3; and S5, embedding and immobilizing the product in step S4.

Description

technical field [0001] The inventive concept belongs to the technical field of polluted water body treatment, in particular, it relates to an immobilized microbial structure and a method for preparing the immobilized microbial structure. Background technique [0002] At present, the treatment of black and odorous rivers mainly includes physical, chemical and biological restoration methods. Physical methods mainly include: sewage interception, dredging, aeration, water diversion, etc. This method has the disadvantages of large amount of engineering, high cost, great impact on the river environment, and easy to cause secondary pollution. The chemical method mainly includes adding chemical agents to react with the pollutants in the water body to remove the pollutants. This method has the disadvantages of many by-products, easy to cause secondary pollution, and unstable treatment effect. Biological method has become a new method for treating black and odorous rivers because of ...
