摘　　要：针对微污染高浊度源水的水质特点,采用接触氧化/生物过滤组合工艺对其进行预处理,并与传统曝气生物滤池(BAF)工艺进行对比。结果表明,接触氧化/生物过滤组合工艺对CODMn、UV254的平均去除率分别为33.3%、23.4%,优于BAF工艺的;而对亚硝态氮和氨氮的去除率分别为81.7%、82.6%,略低于BAF工艺的;对浊度的平均去除率为74.2%,比BAF工艺的高出了约30%;与无预处理工艺相比,接触氧化/生物过滤工艺可使后续混凝处理平均节省23.1%的投药量,而BAF工艺仅节省11%的投药量。The combined process of biological contact oxidation and biofiltration was applied to pretreat micro-polluted source water with high turbidity. A comparison was made between the combined process and biological aerated filter （BAF） process. The results show that the average removal rates of CODM, and UV254 by the combined process are 33.3% and 23.4% , higher than those by BAF. However, the removal rates of nitrite nitrogen and ammonia nitrogen are 81.7% and 82.6% , slightly lower than those by BAF. The average removal rate of turbidity is 74.2% , being 30% higher than that by BAF. An average of 23.1% flocculant dosage is saved using the combined pretreatment process compared to the process without biological pretreatment, which is larger than the 11% dosage saved by BAF.
