摘　　要：污水处理厂尾水中残留有色可溶性有机物(CDOM)直接排放会对环境产生一定影响。使用O_3/H_2O_2工艺深度处理尾水,基于三维荧光光谱,考察反应时间、初始pH、O_3流量、H_2O_2投加量等对尾水中CDOM的去除效果。研究表明,从尾水CDOM中提取出3个有效荧光组分,其中荧光组分C1和C2为腐殖质类物质,荧光组分C3为蛋白类物质,各工艺条件对荧光组分的去除影响显著,蛋白类物质比腐殖质类物质更容易去除。O_3/H_2O_2工艺能够有效去除尾水中CDOM的荧光组分,可为尾水深度处理提供技术参考。The direct discharge of tail water possibly poses a certain impact on the environment,due to the residual of colored dissolved organic matter(CDOM)from wastewater treatment plant.In this study,the tail water from wastewater treatment plant was treated by O3/H2O2 process.Effect of CDOM removal rate by several parameters,such as reaction time,initial pH,O3 flow rate and H2O2 dosage,was discussed based on three-dimensional excitation and emission matrix(3D-EEM)fluorescence spectrum technology.The results showed that three effective fluorescent components were successfully extracted from CDOM,including C1(humic-like),C2(humic-like)and C3(protein-like).Process parameters had significant effect on CDOM removal rate.Protein-like substances was easier to be removed than humic-like substances.The O3/H2O2 process could effectively remove the fluorescent components of CDOM in the tail water and the study could supply technology accumulation for the tail water advanced treatment.
