In the production of enterprises, there are strict requirements for sewage discharge and treatment, and the environmental protection department will always monitor whether the sewage discharge of enterprises meets the standards. In order to ensure the quality of sewage treatment, enterprises usually set up multiple water treatment equipment to treat sewage according to the specific element content. If sulfide exists in sewage, how to deal with it? Now Cangzhou Zhongtian water treatment equipment will discuss with friends: the reinjection or discharge of sewage must meet the national standards, especially the requirements for sulfide content in sewage are very strict, so how to control sulfur and sulfide content? Sulfide has a strong corrosive effect on metals, especially sulfurous acid and sulfuric acid produced in sewage. Among them, inactive sulfide refers to sulfide, disulfide, metallocene, etc. Although they will not directly corrode metals, under certain conditions, sulfurous acid and sulfuric acid will also be generated in sewage, which will cause galvanic corrosion of metal parts and eventually lead to perforation of pipe wall. So how to deal with the water? A certain proportion of strong oxidant can be added to the sewage to make sulfur and sulfide form sulfate, reduce the corrosion of metals, make the sewage clear and reduce the content of suspended solids in the water. However, this water treatment method is unstable in sewage, with short oxidation time and high usage fee, so it cannot be popularized. Controlling the content of sulfur and sulfide in sewage can make the water clear and transparent and easy to treat, which can greatly reduce the economic loss caused by corrosion and prolong the service life of process equipment. Therefore, when using water treatment equipment, it is necessary to increase the replacement cycle of filter materials to ensure the treatment effect of sewage.
