Experimental study on removal of manganese and ferrous ion in groundwater by modified zeolite
改性沸石去除地下水中铁锰实验研究

Two kinds of modified zeolite were chosed to remove manganese and ferrous ion respectively,the basic parameters were analyzed,and processing property in a 0.6 m filler was studied.The results indicated that the total exchange capability of the zeolite for manganese ion removal was 578.2 mmol/kg,and that for ferrous ion removal was 722.2 mmol/kg.The quality of product water could meet the standard: concentration of total ferrous ion lower than 0.3 mg/L and concentration of manganese ion lower than 0.1 mg/L,o...
