摘　　要：研究了粉煤灰在不同条件下处理含Hg2+废水的能力。结果表明,在pH值为9 5左右、吸附时间为40min的条件下,用粉煤灰可将含Hg2+废水浓度从1 6mg·L-1降低到0 022mg·L-1,达到国家规定的排放标准。The treat capacity to wastewater of mercury ion with fly ash is researched under different conditions. The results showed that the fly ash could reduce the wastewater of mercury ion from (1.6 mg·L^(-1)) to (0.022 mg·L^(-1)) at pH range about 9.5 and 40 minutes of adsorption time. The rest concentration met the national discharge standard.
