Research and Application of Wastewater Treatment Technology in Chemical Enterprises
Chemical enterprises inevitably produce a lot of industrial wastewater and sewage in the production process,so different treatment processes need to be adopted to purify sewage and improve water quality.The physical treatment technologies such as filtration,gravity,centrifugation,and membrane permeation separation are easy to operate and suitable for removing suspended substances from chemical wastewater.Chemical treatment technologies such as coagulation sedimentation,neutralization,and chemical conversion can remove heavy metals,highly toxic components,and other pollutants from wastewater.Aerobic biological treatment,anaerobic biological treatment,and combined treatment methods can degrade organic compounds in chemical wastewater and have resource recovery capabilities.The advantages and disadvantages of a single sewage treatment technology vary.Therefore,various treatment methods for sewage treatment in chemical enterprises are introduced to improve the quality of sewage treatment.
