摘　　要：焦化废水生物处理存在的主要问题是系统运行稳定性差、难降解有机物和氨氮去除率低。为此,采用新型好氧-缺氧-好氧生物(O1-A-O2)工艺处理实际焦化废水。实验结果表明,该系统在处理焦化废水过程中运行稳定,系统中O1是有机污染物去除的主要处理单元,而O2是氨氮去除的主要处理单元。系统COD(Chemical Oxygen Demand)总去除率为86%,NH4+-N去除率为61.3%,强化了普通活性污泥工艺处理效果。The main disadvantages of biological treatment for coking wastewater are not effective in removing the refractory organics and NH4^＋ -N, and poor stability. Aerobic （O1）-Anoxic （A）-Aerobic （O2） biological process was put forward for the wastewater treatment. The experiments showed that the new system isstable in operation. The COD and NH4^＋ -N are mainly removed in the first and second aerobic unit respectively. The COD and NH4^＋ -N removals of the O1-A-O2 systems are more than 86 % and 61.3 % respectively and the efficiency of conventional activated sludge process is impro Ded for the wastewater treatment.
