摘　　要：总结了近年来A2/O工艺各段对焦化废水中几种典型难降解有机物(吡啶、吲哚、喹啉等)的降解情况,从降解特性、动力学及机理等方面加以分析,旨在最大限度地发挥厌氧、缺氧及好氧各段微生物的联合降解作用,提高A2/O工艺对焦化废水中难降解有机物的去除效果。The recent study results on the biodegradation of the several typical refractory organics including pyridine, indole and quinoline from coking plant wastewater in A^2/O process were summarized, and the degradation properties, kinetic relationships and mechanism and other aspects were analyzed. The purpose is to furthest exert the combined biodegradation of the anaerobic, anoxic and aerobic reactors and improve the removal efficiency of refractory organics from coking plant wastewater in A^2/O process to the full extent.
