| Abstract: | The particular organic pollutants in coking wastewater are analyzed. And it was emphasized that water quality analysis is the foundation of processes selection for coking wastewater treatment. In view of the complexity of coke production processes,the source and distribution of typical organic pollutants in the processes of ammonia stripping,tar separation,crude benzene recovery and desulfurization are discussed,and the importance and necessary of source control for coking wastewater pollutants are put forward. The pollution control technologies of coking wastewater in the processes of pretreatment,biological treatment and advanced treatment are compared,and it is emphasized that technology innovation and government policy guidance will help for pollution control of the industry and cleaner production in the plant. |
