超滤-颗粒活性炭-紫外线消毒组合工艺制备直接饮用水试验研究

Study on producing direct drinking water by combined process of UF-GAC-UV disinfection

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、CODMn、UV254、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0.155NTU、0.35mg/L、0.009cm-1、0CFU/mL,达到了现行《生活饮用水卫生标准》(GB5749—2006)和《饮用净水水质标准》(CJ94—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。

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,CODMn,UV254 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.
