【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。
[Abstract]:The adsorbents were prepared from oily scum and their adsorption properties were studied. The results showed that the adsorbent was characterized by high carbon content, rough surface and irregular porous structure, and the pore size distribution was mainly mesoporous. The static adsorption results showed that the removal rates of COD and petroleum in oilfield sewage were 91.51% and 87.13, respectively, which were higher than those of wood activated carbon. The results of dynamic adsorption show that the saturated adsorption capacity of COD in oilfield sewage is higher than that of wood activated carbon, and the regeneration result of adsorbent shows that the adsorption effect of COD and petroleum in oilfield sewage after primary regeneration and secondary regeneration is higher than that of ligand activated carbon. The concentration of COD and oil decreased to 37.63 mg / L and 2.183m after the combined use of scum adsorbent and polyaluminum chloride respectively. G/L. It has reached the target requirement of "Liaoning Comprehensive sewage discharge Standard" (DB 21 / 1627-2008).
