Abstract: 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%, NH+4 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.

Key words: fly ash, mineralized refuse, reactive barrier, leachate, groundwater
