摘　　要：对粉煤灰催化铁生物耦合工艺处理某高浓度焦化废水进行了初步试验,发现粉煤灰和催化铁工艺可以较好地和生物法耦合,发挥各自优势,去除难降解有机大分子物质,降低焦化废水毒性提高其可生物降解性,并对CODcr和NH3-N的去除做出了较大贡献,耦合工艺对二者的去除率最高分别达89.64%、74.98%。为焦化废水CODcr、NH3-N难以达到排放标准的难题提供了可能的解决途径。This article carried out a preliminary experiment of using coupling technology of fly ash, catalytic iron and biological method to treat high concentrated eoking wastewater, the results showed that these technologies can couple well and develop their respective advantages to re- move nondegradable big organic molecules, reduce the toxicity of coking wastewater and raise its biodegradability, and therefore contribute a lot to the removal of CODcr and NH3-N, and the removal rate of the coupling technology＂ to CODer and NH3-N can reach 89.64% ,74.98% , respective- ly. These provide a possible solution to the problem that CODer and NH3-N of treated effluent of eoking wastewater can! meet the discharge standard.
