摘　　要：针对官厅水库下游三家店水库水源水进行生物陶粒滤池预处理的现场试验研究。试验结果表明:在气水比为1∶1,滤速6m/h,水温高于5℃的运行条件下,生物陶粒滤池工艺对水中高锰酸盐指数的去除率为10%～18%,氨氮的去除率为80%～98%,出水浊度降低到2NTU以下;气水比为1∶1,滤速4m/h,水温0℃～4℃的情况下,高锰酸盐指数的去除率为5%～12%,氨氮的去除率为65%～80%,出水浊度降低到3NTU以下。This paper reported on the experimental studies using a bio ceramic filter for pre treating the water from Guanting Reservoir, which used to be one of the source waters of Beijing and has been polluted since the late 1980s. The result showed a pretty high removal of ammonium nitrogen even the water temperature close to 0℃. Efficiencies of the filter in terms of removing COD Mn and turbidity under different operating conditions were presented.
