摘　　要：以含油浮渣为原料制备浮渣吸附剂,并研究其吸附性能。结果表明:制备的浮渣吸附剂碳元素含量高,表面粗糙并呈不规则的多孔结构,孔径分布以中孔为主;静态吸附结果显示其对油田污水中COD和石油类的去除率分别可到91.51%和87.13%,大于木质活性炭;动态吸附结果表明其对油田污水中COD的饱和吸附量大于木质活性炭。吸附剂的再生结果表明其一次再生和二次再生后对油田污水中COD和石油类吸附效果始终优于同等条件下再生的木质活性炭。浮渣吸附剂与聚合氯化铝联合使用后处理的油田污水COD和石油类浓度分别降为37.63mg/L和2.183mg/L,达到了《辽宁省污水综合排放标准》(DB 21/1627—2008)中规定的指标要求。A kind of regenerable scum adsorbent and its combination effect with PAC was stud- ied. The results indicate that carbon content is high in the scum adsorbent with rough surface morpholo- gy and irregular porous structure. The pore size distribution is mainly mesopores. The static adsorption show that the removal rate of COD and oil in oilfield sewage is 91.51% and 87. 13% ,respectively,higher than the reference wood-based activated carbon. The saturated capacity of COD in oilfield wastewater is greater than the wood-based activated carbon, proved by the dynamic adsorption results. The regenera- tion experiments indicate that the removal of COD and oil in the wastewater is prior to wood-based acti- vated carbon under equal conditions, even after the first and second regeneration. When the scum adsor- bent is used in combination with poly-aluminum chloride, the COD and oil concentration after treatment can be reduced to 37.63 mg/L and 2. 183 mg/L respectively, meeting the ＂Integrated Wastewater Dis- charge Standard in Liaoning province＂ （DB 21/1627--2008）.
