钢渣、沸石PRB材料修复高铁锰氨氮有机污染地下水实验

AMMONIA NITROGEN AND ORGANIC BY PRB MATERIALS OF SLAG AND ZEOLITE

针对高铁锰氨氮有机污染地下水修复困难的问题,采用静、动态柱模拟实验,进行PRB活性材料的优选及确定最佳组合。实验结果表明:由钢渣与沸石1:1组合构建的PRB新型材料修复高铁锰氨氮有机污染地下水具有良好、稳定的效果,对COD、NH4+-N、Fe2+、Mn2+的最高去除率分别为61.2%、96.3%、99.8%、97.4%。钢渣与沸石的协同作用具有较强的抗冲击负荷能力,实验为钢渣和沸石资源化利用提供了参考依据。

Aimed at the problem that it is difficult to remedy polluted groundwater of high iron manganese ammonia nitrogen and organic, static state experiment and simulation experiment about dynamic column is conducted to optimal select PRB materials and determine optimal portfolio. The results indicate that the new materials of PRB structured by slag and zolite at the rate of 1：1 has favorable removal rates of COD, NFL＋-N, Fe2＋, Mn2＋, being 61.2%, 96.3%, 99.8%, 97.4% respectively. The effect cooperated with slag and zeolite strong anti-shock loading capability and the experiment offers reference for utilizing slag and zeolite.
