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 effect of mesoporous composite adsorbent on the removal of organic pollutants and total phosphorus in micro-polluted water was studied. The results of static adsorption show that the TOC and total P removal rates of mesoporous composite adsorbent are 76.7% and 68.9%, respectively. The saturated adsorption capacity of TOC is 5.27 mg / (g · L) P adsorption capacity was 0.486mg / (g · L). The results of “dynamic adsorption” test showed that the best adsorption capacity of mesoporous composite adsorbent was 35mL / g and the optimum adsorption flow rate was 5mL / min. Under the conditions, the removal efficiencies of TOC and total P were 68.7% and 20.3% respectively. In summary, the overall adsorption effect of mesoporous composite adsorbent and activated carbon is quite, and has certain application value.
