【摘要】 以某自来水厂的水处理工艺为研究对象,考察了各单元对卤乙酸(H AAs)和卤乙酸前提物(H AAFP)的去除效果。结果表明:常规处理单元(混凝、沉淀、过滤)对H AAs几乎没有去除,活性炭(GAC)对二氯乙酸(DCAA)和三氯乙酸(TCAA)的去除率分别是70%和43%,对二氯乙酸前提物(DCAAFP)和三氯乙酸前提物(TCAAFP)的去除率分别是21.5%和27.5%,比常规处理单元的去除率高。更多还原

【Abstract】 Water treatment of a tap water works was investigated to analyze every unit’s removal effect to HAAs and HAAFP. Results showed that there was almost no HAAs removed by means of conventional treatment units such as mixing and coagulating, precipitating and filtrating. Removal efficiency of GAC to DCAA and TCAA was 70% and 43% separately, while GAC to DCAAFP and TCAAFP was 21.5% and 27.5% respectively, which were higher over the removal efficiency of conventional treatment process.更多还原
