Research on the Physicochemical Synergy Technology and Pollutant Removal Mechanism of Coking Wastewater Biological Effluent
The properties of coking wastewater solutions are complex.After biochemical treatment,persistent organic compounds such as polycyclic aromatic hydrocarbons,benzene,and amines remain,which not only pollutes the ecological environment but also poses technical obstacles to water reuse.With the increasing environmental requirements,it is urgent to strengthen the deep treatment process of coking wastewater and achieve"zero discharge"of coking wastewater.This article selects three physical and chemical technologies,namely coagulation sedimentation,activated carbon adsorption,and ozone oxidation,based on the characteristics of biological effluent from coking wastewater to remove organic matter in biological effluent.The synergistic mechanism of physical and chemical technologies and their process effectiveness are examined to provide optimal solutions for the deep treatment process of coking wastewater.
