摘　　要：本文针对变电站事故池含油废水的特点,通过分析比较各项变电站含油废水处理工艺的优缺点,确定了处理工艺方法为“斜板隔油 + 吸附过滤”组合工艺;通过分析比较吸附剂对变电站事故池含油废水的吸附效果,确定了活性炭和纤维棉两种吸附剂对变电站事故池含油废水中COD和石油类进行吸附处理。通过监测分析6座变电站进行设备的实际运行时事故池含油废水的原COD和石油类污染物质浓度,得出结论:虽然未经处理的变电站事故池含油废水的COD和石油类污染物质浓度差异较大,但是经过设备处理后均达到了《污水综合排放标准》(GB8978-1996)第二类污染物最高允许排放浓度一级标准以下,说明设计的设备对COD和石油类处理效果好且具有较高的抗冲击负荷能力。In view of the characteristics of oily wastewater in the substation accident pool, this paper analyzes and compares the advantages and disadvantages of the oily wastewater treatment process of various substations, and determines that the treatment process method is “inclined plate grease trap + adsorption filtration” combination process. By analyzing and comparing the adsorption effect of the adsorbent on the oily wastewater of the substation accident pool, the two adsorbents of activated carbon and fiber cotton were determined to adsorb COD and petroleum in the oily wastewater of the substation accident pool. Through monitoring and analyzing the original COD and petroleum-based pollutant concentrations of the oily wastewater of the accident pool in the actual operation of the equipment in the six substations, it is concluded that although the concentration of COD and petroleum-based pollutants in the oily wastewater of the untreated substation accident pool is quite different;after equipment treatment, they have reached the “Sewage Comprehensive Discharge Standard” (GB8978-1996). The maximum allowable discharge concentration of the second class of pollutants is below the first-level standard, which explains that the designed equipment has a good effect on COD and petroleum treatment and has a high impact load resistance.
