摘　　要：某水厂采用臭氧一生物活性炭(ozone-activated carbon,O_3-BAC)深度处理工艺对淮河微污染原水进行处理,其中溶解性有机物是含碳消毒副产物的主要前体物。研究在某一工况条件,工艺对污染物以及消毒副产物生成势的去除特性。结果表明:O_3-BAC对浊度、COD_(Mn)、DOC、UV_(254)、氨氮的去除率分别为99.8%、82.8%、44.0%、95.4%、97.1%;O_3-BAC对总三卤甲烷生成势(THMFP)以及三氯甲烷生成势(TCMFP)、一溴二氯甲烷生成势(BDCMFP)、一氯二溴甲烷生成势(CDBMFP)、三溴甲烷生成势(TBMFP)的去除率分别是48.7%、65.5%、38.1%、18%、-100.9%;对总卤乙酸生成势(HAAFP)以及一氯乙酸生成势(MCAAFP)、一溴乙酸生成势(MBAAFP)、二氯乙酸生成势(DCAAFP)、三氯乙酸生成势(TCAAFP)、二溴乙酸生成势(DBAAFP)的去除率分别是69.7%、-77.4%、11.4%、76.7%、83.3%、-108.1%。采用预处理、常规处理工艺和深度处理组合工艺可以有效去除水中的污染物,保障出厂水水质安全。In terms of micro-polluted water of Huaihe River, the advanced treatment of O_3-BAC process which mainly aimed to remove DBPs formation potential of DOM had been applied in a water treatment plant. The efficiency of the plant and the removal of trihalomethanes（ THMs） and haloacetic acid（ HAAs） disinfection byproducts formation potential were discussed. The results showed that removal rates of turbidity、COD_（Mn）、DOC、UV_（254）、NH_4~＋-N by 03-BAC were 99.8%、82.8%、44.0%、95.4%、97.1% respectively; total removal rates of THMFP、TCMFP、BDCMFP、CDBMFP、TBMFP were 48. 7%、65.5%、38.1%、18%、-100. 9% respectively; total removal rates of HAAFP、MCAAFP、MBAAFP、DCAAFP、TCAAFP、DBAAFP were 69.7%、77.4%、11.4%、76.7%、83.3%、-108.1%respectively. Combined process of pretreatment, conventional treatment and advanced treatment could effectively reduce pollutants and guarantee the safety of drinking water.
