摘要
实验利用粉煤灰和矿化垃圾两种废物材料作为反应屏障的反应介质用于修复受渗滤液污染的地下水环境。所设计的两个反应器A、B分别填充矿化垃圾和粉煤灰,利用它们的吸附能力、阳离子交换能力以及微生物的作用去除污染质。试验结果表明:A、B两柱COD的去除率最高可达66%和59%,对铵氮的去除率柱A明显优于柱B,最高可达92.7%,并在81%左右保持稳定。另外柱A对硝酸盐氮和亚硝酸盐氮的去除效果也优于柱B。说明矿化垃圾作为反应屏障介质更加经济可行,可以达到以废治废的目的。
Fly ash and mineralized refuse as two kinds of waste were used in reactive barrier in order to treat polluted groundwater which was contaminated by leachate. Two reactors A and B filled with mineralized refuse and fly ash were designed, which have the ability of adsorption, cation-exchange and microorganisms decomposition. The results indicated that COD removal ratios in column A and B were respectively up to 66% and 59%, NH4^＋ removal ratio in column A was up to 92.7%, then stayed at 81% which was better than that in column B. Besides the removal ratios of nitrate and nitrite in column A were higher than column B. In conclusion, mineralized refuse used as medium in reactive barrier was cost-effective and feasible to application, which is a strategy of controlling waste by waste.
