Characteristics of Sulfide Wastewater Methods and Amount of Sulfide Wastewater Treatment Sulfide Wastewater Features Sulfide Wastewater Treatment and Dosage Generally, a typical amount of sulfide is contained in industrial wastewaters, such as domestic sewage, papermaking wastewater, Dyeing wastewater, leather waste, chemical wastewater and some electroplating wastewater contain a small amount of sulfide. The reason for the sulfide is generated because the microorganisms in wastewater play a role in the redox decomposition of sulfate. Sulfide in industrial wastewater is mainly composed of dissolved hydrogen sulfide and acid-soluble metal sulfides, printing and dressing wastewater often contain insoluble sulfides and organic sulfides. Sulphides have an irritating odor and the hydrogen sulphide in the sulphide is highly toxic and can corrode equipment and piping. For the most frequent and effective treatment of sulfide is the use of ferrous sulfate chemical precipitation treatment.
