摘要
研究调查了6种人工甜味剂(ASs)安赛蜜(ACE)、甜蜜素(CYC)、糖精(SAC)、阿斯巴甜(ASP)、三氯蔗糖(SUC)和纽甜(NEO)在城市污水厂不同工艺段的分布、进出水负荷和去除效果。研究表明,进水CYC和SAC含量最多,占ASs总浓度大于67%,而ASP未被检出。ASs进水负荷为0.0037(NEO)~1.32(CYC)g/d·1000p^(-1),出水负荷为0.0015(NEO)~0.43(SUC)g/d·1000p^(-1)。ACE、CYC和SAC去除效率>88%,主要发生在二级处理段,而NEO与SUC去除效率分别<62%和<10%,主要发生在一级和深度处理段。
This study investigated the distribution,mass and emission loads,and removal efficiency of six artificial sweeteners(ASs)including acesulfame(ACE),cyclamate(CYC),saccharin(SAC),aspartame(ASP),sucralose(SUC),and neotame(NEO)in different processes section of sewage treatment plant(STP).The results show that CYC and SAC are the most abundant ASs in STP influent,accounting for>67%of the total ASs concentration,but ASP is not detected in influent.The mass loads of artificial sweeteners in influent range from 0.0037 g/d·1000p^(-1)(NEO)to 1.32 g/d·1000p^(-1)(CYC),while the emission loads in effluent range from 0.0015 g/d·1000p^(-1)(NEO)to 0.30 g/d·1000p^(-1)(SUC).ACE,CYC,and SAC can be effectively removed(>88%)in STP,with most removal occurring in the secondary treatment stage.In contrast,removal efficiencies of NEO and SUC are<62%and<10%,respectively,which mainly occur in the first treatment and advanced treatment stages.
