沸石粉强化混凝处理微污染水源水的试验研究

当前随着水源水污染的日益严重，去除水源水中有机物、氨氮等污染物质的研究受到广泛重视．本文研究了沸石粉投加点、投加量对沸石粉强化混凝处理微污染水源水处理效果的影响．实验结果表明，投加沸石粉强化混凝能够改善絮凝性能，显著提高有机物、氨氮的去除效果．在最佳条件下，沸石粉与复合铝铁复合后的强化混凝，对浊度、CODMn UV254和氨氮的去除率分别达到了92％、46．56％、29．91％和23．5％，而沸石粉与壳聚糖复合后强化混凝对其上述指标的去除率也分别达到了88．7％、33．69％、28．21％和21％．

An Experiment of Powdered Zeolite Enhanced Coagulation in Treatment of Micro-Pollutant Source Water

With seriousness of source water pollution,removal of organic matter and ammonia nitrogen etc.in the source water has been highly focused on.In this paper,relation between effect of powdered zeolite enhanced coagulation and the input place and dose of powdered zeolite was studied.The experiment results show that the powdered zeolite can improve the flocculation behaviors,remarkably enhancing the effect of removing organic matter and ammonia nitrogen.Under optimum conditions,the optimal removal rate of turbidity,COD_(Mn),UV_(254) and ammonia nitrogen are 92%,46.5%,29.91% and 23.5%,respectively,when enhanced coagulation combined powdered zeolite with polymeric aluminum-ferric.However,the optimal removal rate of turbidity,COD_(Mn),UV_(254) and ammonia nitrogen are 88.7%,33.69%,28.21% and 21%,respectively,when enhanced coagulation combined powdered zeolite with chitoson.
