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工艺对其进行处理,第一段BAF主要培养降酚菌,第二段BAF主要培养硝化菌,控制总处理时间为5h,气水比为7,其他控制条件适宜,可以确保处理后的出水酚、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,具有很好的环境效3益和社会效益。

Abstract:
Using zeolite and biological processes for treating coking wastewater was conducted. The result shows that when the processes are used to the activated sludge process, SBR process and A/A/O process, they can reduce the COD of 800 mg/L to 305 mg/L, 221 mg/L and 185 mg/L respectively and can also reduce the influent of NH3-N from 45 mg/L to 9.7 mg/L, 14 mg/L and 13.3 mg/L respectively.
