采用超滤、颗粒活性炭和紫外线消毒组合工艺对自来水进行深度处理.试验表明,对水中浊度、COD_(Mn)、UV_(254)、细菌总数的平均去除率分别为89.8%、90.7%、96.2%和94.5%,以上各参数最终出水平均值分别为0.155 NTU、0.35 mg/L、0.009 cm~(-1)、0 CFU/mL,达到了现行<生活饮用水卫生标准>(GB 5749-2006)和<饮用净水水质标准>(CJ 94-2005)的要求.因此,超滤、颗粒活性炭与紫外线消毒组合工艺用于制备直接饮用水是可行的.
採用超濾、顆粒活性炭和紫外線消毒組閤工藝對自來水進行深度處理.試驗錶明,對水中濁度、COD_(Mn)、UV_(254)、細菌總數的平均去除率分彆為89.8%、90.7%、96.2%和94.5%,以上各參數最終齣水平均值分彆為0.155 NTU、0.35 mg/L、0.009 cm~(-1)、0 CFU/mL,達到瞭現行<生活飲用水衛生標準>(GB 5749-2006)和<飲用淨水水質標準>(CJ 94-2005)的要求.因此,超濾、顆粒活性炭與紫外線消毒組閤工藝用于製備直接飲用水是可行的.

Advanced water treatment by combined process of ultrafiltration-granular activated carbon-UV disinfection was studied.The results showed that the average removal rate of turbidity,COD_(Mn),UV_(254) and TPC were 89.8%,90.7%,96.2% and 94.5% respectively,and the final average value of above parameters in effluent were 0.155 NTU,0.35 mg/L,0.009 cm~(-1) and 0 CFU/mL respectively,which meets the current Standards for Drinking Water Quality(GB 5749-2006)and the Water Quality Standard for Fine Drinking Water(CJ 94-2005).So the combined process of ultrafiltration-granular activated carbon-UV disinfection is practicable for the direct drinking water producing.
