| 摘 要： | 研究了7种常用的人工甜味剂〔安赛蜜、三氯蔗糖、糖精、甜蜜素、纽甜、阿斯巴甜和NHDC(新橙皮苷二氢查耳酮)〕在污水处理厂及自来水厂的分布. 7种人工甜味剂在污水处理厂进水中均被检出,质量浓度为6.4～31 671.0 ng/L. 安赛蜜、三氯蔗糖、糖精、甜蜜素在污水处理厂的出水中被检出,质量浓度为32.4～11 204.0 ng/L. 这些甜味剂将随污水处理厂的出水排放而进入水环境. 安赛蜜、三氯蔗糖、糖精、甜蜜素、纽甜在自来水厂进水中被检出,质量浓度为低于定量限～579.4 ng/L,其中前4种在自来水中被检出,质量浓度为23.3～504.2 ng/L. 沉淀、絮凝、氯化消毒作用对人工甜味剂没有明显的去除作用. 生物降解能有效去除糖精、甜蜜素、阿斯巴甜、纽甜和NHDC,但对安赛蜜和三氯蔗糖去除率不高,去除率均小于20%.

| Abstract: | The occurrence and removal of seven commonly used artificial sweeteners, including acesulfame, sucralose, saccharin, cyclamate, neotame, aspartame and neohesperidin dihydrochalcone (NHDC) in waste water treatment processes (WWTP) and drinking water treatment processes (DWTP) were assessed. All of the seven investigated artificial sweeteners were detected in the influent of WWTP, with concentrations ranging from 6.4-31,671.0 ng/L. The first four artificial sweeteners (acesulfame, sucralose, saccharin and cyclamate) were detected in the effluent, with concentrations ranging from 32.4-11,204.0 ng/L. They might be a contaminant source for surface water. Acesulfame, sucralose, saccharin, cyclamate and neotame were found in the source water of DWTP, with concentrations between
