藻有机物的消毒副产物生成特性研究
isinfection By-products Formation Characteristics of Algal Organic Matters
采用腐殖酸、铜绿微囊藻及其胞外有机物(EOMs)、牛血清蛋白(BSA)、淀粉、DNA和鱼油分别代表和模拟腐殖酸、藻类及其EOMs、蛋白质、多糖、核酸和脂肪，并分别考察这些化合物的三卤甲烷(THMs)、卤乙酸(HAAs)和N-亚硝基二甲胺(NDMA)生成情况。结果表明，这七种有机物样品的THMs生成势分别为2.46、11.55、4.01、3.60、0.75、3.08、17.57 μg/mg TOC，HAAs生成势分别为4.46、14.82、5.28、10.60、1.68、5.70、4.64 μg/mg TOC，NDMA生成势分别为0.293、0.216、0.054、0.212、0、0.215、0 μg/mg TOC。综合比较可知，除淀粉外的其它藻有机物样品均具有较腐殖酸更高的THMs和HAAs生成势，而腐殖酸则具有较所有藻有机物样品更高的NDMA生成势。
Humic acid, M. aeruginosa, extracellular organic matters (EOMs) of M. aeruginosa, bovine serum albumin (BSA), starch, DNA and fish oil were used as surrogates of humic acids, algae, algal EOMs, proteins, carbohydrates, nucleic acids and lipids for investigating their THMs, HAAs and NDMA formation characteristics. The results showed that THMs formation potential of them was 2.46、11.55、4.01、3.60、0.75、3.08、17.57 μg/mg TOC, HAAs formation potential of them was 4.46、14.82、5.28、10.60、1.68、5.70、4.64 μg/mg TOC, NDMA formation potential of them was 0.293、0.216、0.054、0.212、0、0.215、0 μg/mg TOC, respectively. It indicated that except starch, other algal organic matters samples all showed higher THMs and HAAs formation potential than humic acids. However, humic acids showed the highest NDMA formation potential than all algal organic matters samples.
