中文摘要：

研究了MIEX-HCO3型和MIEX-Cl型树脂在城市生化尾水深度处理中的应用。结果表明。MIEX-HCO3型树脂与MIEX-Cl型树脂在温度25℃、转速130r/mim下均于50min内达到吸附平衡。MIEX-HCO3型树脂对水中UV254的去除效率与MIEX-Cl型树脂相当，约为80％左右，但当水中Cl^-的质量浓度由30．0mg／L升至158．4mg／L时，MIEX-HCO3型树脂对UV254的去除率由83％降至46％。三维荧光谱图的分析结果表明，MIEX-HCO3型树脂对不同类型水中的腐殖酸类物质去除效率均较高，而对芳香蛋白质Ⅰ去除效果略差。

英文摘要：

The application of the MIEX-HCO3 and MIEX-Cl resins in advanced treatment of the urban secondary effluents was studied. The results exhibited that both of the MIEX-HCO3 resin and the MIEX-Cl resin achieved the adsorption equilibrium in 50 min at 25 ℃ in 130 r/min and have equivalent UV254 removal efficiency about 80%. However, for MIEX-HCO3 resin, when the mass concentration of Cl^- increased from 30.0 mg/L to 158.4 mg/L, the UV254 removal efficiency decreased from 83% to 46%. The fluorescence spectra recorded at excitation-emission matrix （EEM） revealed that the adsorption of MIEX-HCO3 resin caused a significant decrease of the aromaticity of humic-like structures and a minor decreased of Aromatic protein I.
