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87.14%,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37.63 mg/L和2.683 mg/L,达到了《辽宁省污水综合排放标准》(DB21/1627—2008)中规定的指标要求。

Abstract: A kind of scum adsorbents was prepared from oily scum and its adsorption performance was studied. The results indicate that carbon content is high in the scum adsorbent with rough surface morphology 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 regeneration experiments indicate that the removal of COD and oil in the wastewater is prior to wood-based activated carbon under equal conditions, even after twice regenerations. When the scum adsorbent 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 Discharge Standard in LiaoNing province”(DB21/1627—2008).
