摘要

  • 摘要: 以八羟基喹啉为改性剂,天然膨润土为原料,制备一种新型吸附剂,并将其应用于养殖废水的预处理中。确定了改性膨润土的最佳制备条件:土液比为4 g/L,改性剂浓度为0.3 g/L,改性时间为50 min,改性温度为50℃。并以扫描电镜方法对改性膨润土行进表征:八羟基喹啉已经有效进入层间,改变了膨润土的性状,提高了吸附效果。优化了改性膨润土处理养殖废水的工艺条件:投土量为1 g/L,pH为4,搅拌时间为30 min,搅拌速度为350 r/min,沉淀时间为40 min。在此优化条件下,改性膨润土对养殖废水的COD去除率最高可达79.18%,且吸附动力学结果满足二级动力学模型。
    Abstract: A new adsorption material was synthesized using 8-hydroxyquinoline and natural bentonite. And the new type of adsorbent was applied to pretreat aquacultural wastewater. The modified bentonite optimal synthesis conditions were studied: the solid-liquid of 4 g/L, cross-linker concentration of 0.3 g/L, contact time of 50 min, reaction temperature of 50℃. The structural characterization and morphology of the modified bentonites was observed by means of scanning electron microscopy. The 8-hydroxyquinoline entered into the bentonite interplanar space effectively. Some characters of the bentonite were changed and the adsorption effects were improved. The reaction conditions of aquaculture wastewater pretreatment on modified bentonite were optimized as follows: adsorbent dosage of 1 g/L, pH of 4, adsorption time of 30 min, stirring speed of 350 r/min, sedimentation time of 40 min. The result showed that the COD removal rate reached 79.18%. By kinetic calculation, it was proved that the adsorption reaction was consistent with the secondary dynamic model.
