The Biodegradation of PAHs Involved in Coking Wastewater Biological Treatment Process

Coking wastewater was typical industrial wastewater with high concentration of polycyclic aromatic hydrocarbons (PAHs). we provided an overview of the biological treatment process of coking wastewater, the sampling and analysis of PAHs in process, the structural characteristics of PAHs and the biodegradation of PAHs involved in coking wastewater biological treatment process. The unknown PAHs biodegradation dynamics and response characteristics of functional microbiology groups hinder the coking wastewater biological treatment, which induce the control of PAHs in coking wastewater with limited efficiency. Based on the PAHs in coking wastewater, we introduce the research Progress of the characteristics of PAHs and the biodegradation of PAHs , which would provide new theories on the unit design, process control and directorial screening of functional microbiology in coking wastewater with high PAHs concentration.
