高铁锰氨氮有机污染地下水的钢渣与沸石可渗透性反应材料处理特性试验

Characteristic Experiment on Treatment of Polluted Groundwater of High Iron Manganese Ammonia Nitrogen and Organic by PRB Materials of Slag and Zeolite

研究钢渣和沸石作为可渗透性反应墙6,va3）活性材料处理含高铁锰、氨氮、有机物污染地下水的有效性和反应特性。结果表明，钢渣和沸石处理污染物的最佳粒径、投加量、反应时间、振荡频率分别为：0．297．-0．595mnl、5g／100mL、120min、150r／min和0．297-0．595mm、5g／100mL、90min、150r／min，钢渣和沸石在质量比为5：5（g：曲的最佳配比下，对COD、NH4-N、Mn”、Fe。‘降低率分别为59．8％、91．7％、93．1％、98．5％。

Effective and responsive characteristics of slag and zeolite are studied, as PRB active materials to treat polluted groundwater of high iron and manganese, ammonia nitrogen and organic. The results show that the optimum particle size, dosage, time, oscillation frequency of treatment pollutants of the slag and zeolite are： 0.297~0.595 mm, 5 g/100 mL, 120 min, 150 r/min and 0.297-0.595 mm, 5 g/100 mL, 90 min, 150 r/min respectively. Decrease rates to COD, NH4-N, Mn2~, Fe2~ by the slag and zeolite are： 59.8%, 91.7%, 93.1%, 98.5% respectively under the best quality ratio of 5 ： 5 （g ： g）.
