How to prevent corrosion of buried sewage treatment equipment?


Buried sewage treatment equipment is often used in various domestic sewage treatment projects. Due to the long design period of the project, the anti-corrosion and anti-rust work of the equipment has attracted much attention. This problem is also a problem that plagues the manufacturers of various sewage treatment equipment. The rust measures are not in place, and the equipment is easily damaged in advance, causing great trouble to the user. So how do underground sewage treatment equipment do rust prevention? Today, Kinglv  Environmental Protection will bring you some common measures.

There are two main aspects of anti-corrosion work for buried sewage treatment equipment, namely the housing of the equipment and the internal pipe. At present, the equipment on the market is mainly divided into glass steel and carbon steel. FRP material is inherently resistant to corrosion and does not require special anti-corrosion coatings. Carbon steel equipment must be coated with a suitable anti-corrosion coating on the inside and outside of the casing. Polyurethane, epoxy resin and other coatings are widely used anti-corrosion coatings 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 selected. Most metal pipes are not suitable for sewage treatment equipment, and even if they are coated with anti-rust paint, it is difficult to extend their life. Therefore, the pipe of the equipment should be made of high quality PVC pipe.
