Abstract

The invention provides a coating for a sewage treatment device. Epoxy resin, novolac epoxy resin, carbon black, titanium dioxide, mica powder, zinc borate, antimony trioxide, decabrominated dipheny ethane, barium carbonate, vermicular carbon, polyglycerol polyricinoleate, 3-hydroxybenzoic acid, lauryl sulfate, plant saponin, ginger liquid, terpilenol, sulfur and barium stearate are added to a high-speed mixing machine in proportion and are fully and evenly mixed; the mixture is extruded by an extruder, the extruded sheets are pulverized in a pulverizer, and then screening and packaging are performed to obtain a product. The coating has excellent resistance to high temperature and corrosion and has excellent anti-cathodic stripping property under high temperature condition.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a coating used for sewage treatment. Background technique [0002] In the field of sewage treatment, due to the advantages of excellent effluent quality, simple operation, low sludge production rate, and small footprint, the membrane bioreactor has continuously expanded and increased its application range and scale in sewage treatment. Separation membrane is the most important component in membrane bioreactor, and its performance is very important to the performance of sewage treatment. Traditional membrane separation materials generally include polyvinyl alcohol, polysulfone, polysulfone amide, polyacrylonitrile, polyvinyl chloride, chitosan and various modified celluloses. These membrane separation materials have serious problems in actual use. Due to the membrane fouling situation, it is difficult to promote and apply on a large scale. [0003] As early as more than 200 years...
