摘　　要：采用共代谢生物处理系统对焦化废水进行深度处理。通过单因素试验,探讨了HRT对COD去除率的影响;采用GC-MS对最佳HRT下各工艺段的有机物组分进行了分析,以探究COD变化机理。结果表明,在HRT为24h的条件下,经过共代谢生物处理系统处理的焦化废水的水质达到GB8978-1996中的第2类污染物最高允许要求;吡啶等难降解物质被部分降解,环烃类物质逐步降解开环。We treat coking wastewaterin depth by co-metabolism biological treatment system. The HRT on COD removal rate explored by single factor experiments and using GC-MS analytical techniques to explore the mechanism of COD change, at the optimal HRT, each process underparagraphs organic components were analyzed. The results showed that underthe HRT of 24 h, the waterquality which was disposed by co-metabolism biological treatment system had reached the national secondary standards （GB 8978-1996）; Pyridine and otherstubborn materials are partially degraded; cyclic hydrocarbons were gradually subdued by ring-opening.
