Problems solved by technology

However, due to factors such as the density of reactive groups on the carrier and the efficiency of the grafting reaction, the grafting efficiency is not high, and the increase in the biodegradation rate of azo dyes, nitrates, etc. cannot meet people's expectations, and there are still problems in recycling. inconvenient

Abstract

The invention belongs to the technical field of waste water treatment, and in particular relates to a preparation method of a modified fluorosilicon polymer, a fabric and its application. A fluorosilicon polymer containing chloropropyl and vinyl groups and an amino-containing anthraquinone compound are used as an acid-binding agent Under the action of dehydrochlorination, the modified fluorosilicone polymer is obtained; then, the incompatibility between the modified fluorosilicone polymer and the silicone rubber is used to precipitate and enrich the surface to obtain anthraquinone with a higher content on the surface. The fabric of the invention has a better promoting effect on the biodegradation of azo dyes and nitrates.

Description

Technical field [0001] The present invention belongs to the technical field of wastewater treatment, a modified method for preparing the fluorosilicone polymer, the fabric and its application. Background technique [0002] Azo dyes, nitrates, etc. The extensive use of environmental pollution has attracted considerable attention, anaerobic degradation thereof having good prospects, and a redox mediator anthraquinone compounds and the like to improve their physical fitness 1 the degradation rate of magnitude more. However, in order to avoid direct use of an anthraquinone compound or the like due to water "secondary pollution", which is reported to be available by a chemical reaction in the grafting polymer film (Publication No. CN103936146B), fillers (Publication No. CN110066009A) carrier such as surface to achieve avoid entering water and recyclable. However, the density of reactive groups on the carrier is limited to, such factors as the efficiency of the grafting reaction, graft...
