Who knows how to deal with the sulfide in the sewage, and what needs to be considered in the treatment process?

Enterprise production, the treatment of sewage discharge has strict requirements, the environmental protection department will always monitor the enterprise's sewage discharge is up to standard. Enterprises in order to ensure the quality of sewage treatment, generally set up a number of water treatment equipment, and according to the specific elemental content of sewage, water treatment. If there is sulfide in the sewage, how to carry out water treatment? Now, Cangzhou City, in the sky water treatment equipment and friends to recognize and explore: sewage reinjection or discharge must meet national standards, especially on the sewage sulfide content requirements are very strict, then how to control sulfur and sulfide content? Sulfide corrosion of metals is very strong, the generation of sulfite and sulfuric acid in the sewage is more so. One of the inactive sulfide refers to sulfur ether, disulfide and thiomao, etc., although it will not directly corrode the metal, but under certain conditions, but also in the sewage to generate sulfite and sulfuric acid, the formation of the metal parts of the primary cell chemical corrosion, ultimately leading to perforation of the pipe wall. So how to treat the water? Can be added to the sewage to a certain percentage of strong oxidants so that sulfur and sulfide formation of sulfates, reduce the corrosion of metals, so that the sewage becomes clear, reduce the content of suspended solids in the water, but the water treatment because of the instability of the sewage, and the oxidation of short duration, the use of the cost of high and can not be popularized and popularized. Control the amount of sulfur and sulfide in the sewage, so that the water quality is clear and transparent, easy to deal with, can significantly reduce the economic losses caused by corrosion, and extend the life of process equipment, so in the use of water treatment equipment, the need to increase the replacement cycle of the filter canister filter media to ensure that the sewage treatment effect.
