摘　　要：考察了有机物、NH4^＋-N、NO2^--N、NO3^--N和总氮浓度沿饮用水系统生物滤池高度的变化。结果表明：生物滤池对有机物的去除作用主要发生在进水端前300mm的范围内，在这段滤层内，反应器对有机物（CODMn）的去除率为23。1％，占总去除率的97．47％；在进水端前200mm的范围内反应器对氨氮的去除率为45．29％，占总去除率的90．14％；在滤层高度为0～1000mm这一范围内，亚硝态氮浓度呈下降趋势，没有发生亚硝态氮的积累；在进水端200mm处，硝态氮浓度的增幅达到最大；在滤层高度为200～1000mm处发生了氮亏损现象。The variation of organic matter, ammonia nitrogen, nitrite nitrogen, nitrate nitrogen and total nitrogen with drinking water biofilter depth was investigated. The results show that the removal of organic matter mainly occurs in the 0 to 300 mm of biofiher, the removal rate of organic matter is 23.1%, which is 97.47% of the total removal rate. In the 0 to 200 mm of biofiher, the removal rate of ammonia nitrogen is 45.29%, which is 90.14% of the total removal rate. In the 0 to 1 000 mm of biofiher, nitrite nitrogen is in a downward trend, and the accumulation of nitrite nitrogen does not happen. In the 200 mm of biofilter, the increase rate of nitrate nitrogen reaches the maximum. In the 200 to 1 000 mm of biofilter, there is the loss of nitrogen.
