The Biodegradation of PAHs Involved in Coking Wastewater Biological Treatment Process

焦化废水是含高浓度多环芳烃工业废水的典型代表。基于焦化废水生物处理过程多环芳烃的生物降解，概述了焦化废水的生物处理工程，焦化废水生物处理过程的PAHs采样分析，焦化废水生物处理过程多环芳烃的结构特征，焦化废水生物处理过程多环芳烃的微生物降解。尤其是对执行降解功能的微生物菌群特征缺乏深入了解，导致对焦化废水多环芳烃生物处理工艺的控制带有盲目性。针对焦化废水中多环芳烃类有机污染物，重点介绍了焦化废水生物处理过程多环芳烃的结构特征及其生物降解前沿，为更好地开展相关研究提供参考，有望为焦化废水中多环芳烃生物降解的工艺设计、过程监控以及功能微生物的定向筛选提供新的理论依据。

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 PAl-Is 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 biodegmdation 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.
