| 中文摘要 | 污水再生利用是解决我国城市水资源短缺的有效途径,消毒是保证再生水水质安全的必要措施。氯消毒可以有效杀灭病原微生物,但同时也会生成各种具有毒性和“三致”效应的消毒副产物。由于含氮有机物是污水氯消毒副产物的一类重要前体物,故选取20种基本氨基酸为研究对象,考察了它们经氯消毒后生成三氯甲烷、卤乙酸、卤乙腈、三氯硝基甲烷、1,1-二氯-2-丙酮和1,1,1-三氯-2-丙酮的潜能。结果表明,各种氨基酸的消毒副产物生成潜能与它们的R基结构密切相关,其中R基上带有活性苯环的色氨酸和酪氨酸均表现出了较高的三氯甲烷、卤乙酸和卤乙腈生成潜能。; Wastewater reuse is an effective solution to mitigate water shortage problems in urban areas,and disinfection is necessary to ensure the quality of the reclaimed water.Although chlorine has been widely used to kill pathogenic organisms,it produces disinfection byproducts that contain toxicity,mutagenicity,carcinogenicity and teratogenicity.Nitrogenous organic compounds are important disinfection byproduct precursors.The formation potentials of chloroform,haloacetic acids,haloacetonitriles,chloropicrin,1,1-Dichloropropanone,and 1,1,1-Trichloropropanone during the chlorination of 20 elementary amino acids were studied.The results show that the formation potentials of the disinfection byproducts of the amino acids are related with their-R structures.Tryptophan and tyrosine with active phenyl in their-R structures have high formation potentials of chloroform,haloacetic acids and haloacetonitriles.; NFSC-JST重大国际合作项目(20510076); 国家自然科学基金资助项目(20277025) |
