饮用水中典型含氮消毒副产物卤乙腈的质量浓度分布
Concentration Distribution of Typical Nitrogenous Disinfection By-products HANs in Drinking Water
摘要
Abstract
The concentration distributions of three kinds of typical nitrogenous disinfection by-products ( N-DBPs) haloacetonitriles ( HANs): dichloroacetonitrile ( DCAN), bromochloroacetonitrile ( BCAN ), dibromoacetonitrile (DBAN) in water after sedimentation, filtration and finished water with the seasons were surveyed. The results show that 3 HANs levels maximized in summer and early autumn, and the concentrations of DBAN and BCAN were influenced by the concentration variation of Br- in raw water. Significant linearrelationships between raw water DON and DCAN concentration in water after sedimentation and filtration were found (water after sedimentation: R2 = 0. 893; water after filtration: R2 = 0. 892); while no obvious liner relationship between DCAN concentration and raw water DOC was obtained. The linear relationships between BCAN concentration and raw water DON, DBAN concentration and raw water DON were weaker relatively, and relationships between their concentrations and DOC were not obvious. Bromine distribution coefficient (nBr) of HANs was higher in the saltwater tide period. The control of brominated N-DBPs in this period should be taken seriously.关键词
