The activation and regeneration of mordenite was studied by its removing efficiency of COD and NH N . The optimal activation method was Mn 3 determined as follows :roasted at 700 ℃for 25 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 . Key words : zeolite ; slightlypolluted water ; activation ; regeneration 　　沸石是沸石族矿物的总称 ,是一种含水的碱金
