| 摘 要： | 讨论了中国南方某城市自来水厂饮用水中的多环芳烃残留规律以及现有净水工艺对多环芳烃的去除效果。研究结果表明,该自来水厂饮用水中检出多环芳烃以2~4环芳烃为主,强致癌性高环数多环芳烃均在检出限以下,且多环芳烃总量未超出中国供水行业标准(2000年)的相关限值。各处理工艺段中,砂滤过程对多环芳烃的去除效果最好,相较于原水对多环芳烃总量的去除率可达64%。

| Abstract: | Residual PAHs in the drinking water and removal efficiency of PAHs by purified water technique in a municipal waterworks in the south of China were discussed. The results showed that PAHs detected in the drinking water of the waterworks mostly consisted of 2~4 ring aromatic hydrocarbons. Concentrations of high-ring PAHs which are known to be strongly carcinogenic were under the detection limit. The total PAHs did not exceeded the relative limit of water supply industry standard in China (2000). The process of sand filtration was the most efficient treatment stage for removal of PAHs. The removal efficiency of total PAHs came up to 64% in comparison to the raw water. |
