  • 摘要: 利用三维荧光光谱法、紫外分光光度法和动态光散射技术，研究城市污水二级出水中溶解性有机物（DOM）与Cu2+作用的粒径变化、光谱特性和络合能力.结果表明，利用修正型Stern-Volmer方程得到二级出水DOM与Cu2+作用的条件稳定常数（lgK）和配位荧光官能团比例分别为1.74—2.59和8.77%—39.44%.在一定实验范围内，随投加Cu2+浓度和pH增大，二级出水DOM和Cu2+作用后的UV253/UV203值增大.pH值为7—9时，随pH增大，荧光强度基本增强而荧光指数降低；相同pH下，随投加Cu2+浓度增加，荧光强度降低而荧光指数增大.表明二级出水DOM络合Cu2+，改变两者在水中的存在状态和迁移.pH 7时，DOM与Cu2+有较高的络合稳定性和络合能力.
    Abstract: A laboratory study was conducted to investigate the aggregation, spectral properties and complexing ability of dissolved organic matter (DOM) in secondary effluent of municipal sewage with Cu2+ by using three-dimensional fluorescence spectroscopy, UV spectrophotometry and dynamic light scattering technique. Using the modified Stern-Volmer equation the conditional stability constant (lgK) and the proportion of fluorescent functional groups of the DOM binding with Cu2+ were calculated to be 1.74-2.59 and 8.77%-39.44% respectively. The UV253/UV203 values increased with the increases of the Cu2+ concentrations and pH in a certain range. The fluorescence intensity was substantially strengthened and the fluorescence index(FI) reduced with increasing pH at pH 7-9. However, the fluorescence intensity decreased and the FI increased with increasing the Cu2+ concentration at the same pH. It could be concluded that the secondary effluent DOM complexed with Cu2+changing their state and migration in water. DOM had higher complexing stability and binding ability with Cu2+ at pH 7.
