摘　　要：以丝光沸石处理济南某水库微污染水为例,通过实验考察沸石去除水中CODMn、NH3-N的效能,研究沸石的活化和再生。提出了此类沸石的最佳活化方法为:温度700℃、焙烧2.5 h后,再用5%的NaCl溶液浸泡3 h;最佳再生方法为直接用5%的NaOH溶液浸泡3 h。A mordenite was used to treat slight-pollution water from a reservoir of Jinan City.The activation and regeneration of mordenite was studied by its removing efficiency of COD_(Mn) and NH_3-N.The optimal activation method was determined as follows:roasted at 700℃ for 2.5 h,then dipped in 5% NaCl solution for 3 h.The optimal regeneration method for zeolite was only dipping it in 5% NaOH solution for 3 h.
