Problems solved by technology

Organic biofilm carriers are divided into artificially synthesized polymer carriers and natural degradable polymer carriers. Artificially synthesized polymer carriers include polyethylene, polypropylene, polyurethane foam, etc., with large specific surface area and high porosity, but biological The compatibility is not good, and it will cause secondary pollution. The degradable polymers include chitosan, cellulose, etc., which are non-toxic to microorganisms, have good biocompatibility, and good mass transfer performance, but they have been decomposed
The currently widely used microbial carriers in biofilm technology have exposed many shortcomings in terms of biological affinity, stability, mechanical properties, film-hanging effect and regeneration treatment, which restrict the development of biofilm water treatment technology.

Abstract

A preparation method of a microbial affinity water-treatment light carrier is disclosed. The preparation method comprises the following steps: 1, fetching 40-55 parts by weight of tourmaline, 12-34 parts by weight of dry sewage sludge, 8-16 parts by weight of fly ash, 7-12 parts by weight of a flux, 8-15 parts by weight of a pore-forming agent and 6-10 parts by weight of an adhesive, and uniformly mixing the above materials; 2, adding water into the above mixture according to the water-to-material ratio of 6-7:10, stirring for 2-3 h until the mixture is uniformly mixed, and carrying out artificial granulation; 3, naturally drying the carrier granular raw material, carrying out heat preservation, and drying until water content is 10-30%; and 4, putting the granular raw material into a muffle furnace and firing. The product is characterized by large specific surface area and high porosity. According to the invention, a growth environment for microbes can be improved, microbial affinity of the carrier can be raised, and enzymes metabolic activity of cells in microbes can be enhanced. Then, sewage treatment efficiency is raised. The invention can be applied to industrial, agricultural and urban sewage treatment and the like.

Description

technical field [0001] The invention relates to a method for preparing a microbial affinity water treatment light carrier. Background technique [0002] With the rapid development of industrial technology and the acceleration of population urbanization, the problem of water pollution has become increasingly serious, which not only affects people's physical and mental health, but also hinders the further development of society. Therefore, technology needs to be improved to meet the needs of the current society. Therefore, wastewater treatment technology has become a key issue of concern in the world. Among the current technologies, biofilm method is the focus of biological wastewater treatment technology. [0003] The biofilm method utilizes microorganisms attached to and grown on certain solid surfaces (ie, biofilms), and through the exchange of solid and liquid phase substances, pollutants are degraded by microorganisms on the surface of the carrier. The solid medium attac...
