粉末活性炭和超滤膜组合工艺深度处理黄浦江原水

Study on Advanced Treatment of Raw Water of Huangpu River by Combination Process of PAC and UF

目的为了提高黄浦江原水中溶解性有机物的去除效果,进一步提高上海自来水水质.方法采用粉末活性炭(PAC)和超滤膜(UF)组合工艺深度处理黄浦江原水.结果粉末活性炭投加量增加可以提高工艺对水体中有机物的去除效果.在投加量为22.0 mg/L的条件下,对CODMn、UV254和TOC的去除率分别为33.5%、40.67%、25%,出水CODMn可以达到国家水质标准的要求.该工艺能够有效地保证出水浊度,也能够有效地降低出水的致突变活性.结论PAC和UF组合工艺能有效地降低水体中溶解性有机物的浓度,减少消毒过程中三卤甲烷和四氯化碳的生成量.采用PAC和UF组合工艺深度处理黄浦江原水是可行的.

The purpose of the study is to enhance the eliminating efficiency of the dissolved organic substance in original water of Huangpu River so as to obtain the high quality tap water. A combination of powder activated carbon （PAC） and ultrafiltration（UF）is used to have an advanced treatment on the original water of Huangpu river. The result shows that the eliminating ratio is respectively 33. 5 %, 40.67 %, 25 % to CODMn, UV254 and TOC under the conditions of 22.0mg/L powder activated carbon added in water, which can meet the national standard. This technique can guarantee the water - yielding turbines effectively and reduce the mutagenic activity. Therefore, it is feasible to use the combination of PAC and UF to have a deep treatment on the original water of Huangpu River.
