How to prevent corrosion of buried sewage equipment?

When people use integrated sewage treatment equipment, they will consider the anti-corrosion problem of the equipment. The anti-corrosion problem is a difficult problem that puzzles manufacturers. Due to sewage corrosion, if it is not handled correctly, the equipment will easily rust. So how to prevent the integrated sewage treatment equipment from corrosion? Due to the complex composition of urban sewage, the corrosion of steel equipment in sewage treatment plants is a common phenomenon. This is because sewage contains nutrients, minerals and hydrogen sulfide gas. Hydrogen sulfide gas is a highly corrosive and deadly substance. This gas is combined with several other minerals, including the change of PH value and the mineral used to treat sewage, as well as the fluctuation of temperature, which are the reasons for the failure of many coatings. The anti-corrosion work of buried sewage treatment equipment mainly includes two aspects, namely, the shell of the equipment and the coffin inside. At present, the equipment on the market is mainly divided into FRP and carbon steel. Glass fiber reinforced plastic material has good corrosion resistance. No special anticorrosive paint is needed. Carbon steel equipment must be painted with appropriate anticorrosive coatings inside and outside the shell. Polyurethane, epoxy resin and other coatings are widely used in water treatment equipment. Domestic sewage contains organic nutrients, compounds and hydrogen sulfide gas. Hydrogen sulfide gas is a highly corrosive and deadly substance. Therefore, the pipes inside the buried sewage treatment equipment need to be carefully selected. Most metal pipes are not suitable for sewage treatment equipment, and even if they are coated with antirust paint, it is difficult to effectively extend their life. Therefore, the coffin of the equipment should be made of high-quality PVC pipes. Dilin New Materials (Jiangsu) Co., Ltd. provides you with high-quality and long-term anti-corrosion solutions.
