介孔复合吸附材料对微污染水源水中有机污染物的吸附试验

研究介孔复合吸附材料对微污染水源水中有机污染物和总磷的去除效果。静态吸附试验结果表明,介孔复合吸附材料对微污染水源水的TOC和总P去除率分别为76.7%和68.9%;TOC饱和吸附量为5.27mg/(g·L),总P饱和吸附量为0.486mg/(g·L);动态吸附试验结果表明,介孔复合吸附材料的最佳处理量为35mL/g,最佳吸附流速为5mL/min,在此条件下对TOC和总P的去除效果分别为68.7%和20.3%。综上所述,介孔复合吸附材料的整体吸附效果与活性炭相当,具有一定的应用价值。

THE ADSORPTION EXPERIMENT OF MESOPOROUS COMPLEX ADSORPTION MATERIAL USED FOR DISLODGING SOME ORGANIC POLLUTANTS IN A SLIGHTLY-POLLUTED HEADWATER

A mesoporous complex adsorption material(MCAM)was used for dislodging some organic pollutants in a slightly-polluted headwater with the static and dynamic adsorption experiments. The results of the static adsorption experiment showed that MCAM's dislodgement rate of the TOC was 76.7%,and that of TP was 68.9%. The saturation adsorption quantity was as follows:TOC= 5.27 mg/(g·L); and TP= 0.486 mg/(g·L). The results of the dynamic adsorption experiment showed that the best treatment capacity of MCAM was 35 mL/g ; and the velocity of flow was 5 mL/min. Under this condition,the removal rates of TOC and TP were 68.7% and 20.3%. To sum up,the adsorption effect of MCAM was equivalent to that of activated-charcoal.
