摘　　要：以长江陈行水库原水为研究对象,对比炭砂生物滤池和普通快速滤池对水中CODMn、UV254、氨氮的去除效果,评价炭砂生物滤池出水生物稳定性。结果表明:炭砂双层滤料具有良好的强化过滤效果;炭砂生物滤池出水CODMn均值为0.86 mg/L,平均去除率53.9%;UV254均值为0.017 cm-1,平均去除率64.4%;炭砂生物滤池对氨氮的平均去除率为84.1%;该工艺出水AOC为45μg/L,生物稳定性较好。Taking the raw water of Yangtze Chenhang Reservoir as the research object,the removing efficiencies of CODM,, UV254, ammonia-nitrogen in water by GAC-sand biological filter and ordinary rapid sand filter are contrast ed, and its effluent biological stability by GAC-sand biological filter process are evaluated. The results show that the two layer GAC-sand filter has favorably enhanced filtration efficiency. The average concentration of CODMn in GAC- sand filter effluent is 0.86 mg/L, average removing rate 53.9%. The average value of UV254 is 0.017 cm-1 and average removing rate of it can reach 64.4%. The average removing rate of ammonia-nitrogen by GAC-sand filter is 84.1%. The effluent AOC of this process is 45 μg/L, having good biological stability.
