摘　　要：炼油厂汽提废水因含有较高浓度的酚和COD,会对污水处理场产生冲击;若能对其进行分流处理使之达到排放标准,则可以消除它对水环境的污染。研究结果表明,采用二段曝气生物滤池(BAF)工艺对其进行处理,只要条件控制得当,便可确保处理后的出水中酚、COD、石油类、硫化物和NH3-N等各项污染指标达到国家规定的污水排放标准,从而达到很好的环境效益和社会效益。Wastewater discharged from stripping tower, containing highly concentrated phenol and COD, can bump against wastewater treatment plant. If it can reach the discharge standard by separated treatment, pollution to water environment can be removed. The experiment results show that the effluent concentration for phenol, COD, oil, sulphide and NH3 - N can be ensured to reach the stipulated discharge standard with the two-stage BAF, if the associated conditions are properly controlled, which may create great environmental and social benefits.
