三维特征荧光参数可以反映污水处理过程中污染物的种类、性质和含量变化等丰富信息。通过对水样进行三维荧光特性分析和常规有机污染物指标COD ，TN ，TP的对比分析，确定表征污水中溶解性有机污染物种类、组成和含量的三维特征荧光。对进水、间隙水和出水中DOM 的四种不同组分的荧光光谱图、荧光峰值（R.U.）、荧光指数FI、腐殖化指数HIX以及与COD ，TN ，TP的相关性进行研究可知：污水处理前后特征荧光峰中心位置和强度均发生明显的改变，表明污水中有机物的相对组成和含量随处理过程而变化；类腐殖质组分的降解情况不显著，而类蛋白组分的降解情况显著，类蛋白组分与COD ，T N ，T P呈现显著正相关。采用三维荧光光谱法分析了污水处理过程中溶解性有机物的荧光特性变化规律，探讨三维荧光技术用于描述污水处理过程中溶解性有机污染物降解规律的可行性。

Three‐dimensional fluorescence parameters can reflect classification ,properties and content change of pollutants in wastewater treatment .In the present paper ,by using three‐dimensional fluorescence characteristic analysis ,comparative analysis of conventional organic pollutants such as COD ,TN and TP ,and three dimensional fluorescence spectrum analysis ,the classifi‐cation and content of dissolved organic pollutants were identified .We studied fluorescence spectra ,fluorescence peak (R .U .) , fluorescence index (FI) ,humification index (HIX) of DOM’s four components in the entrance and effluent water and interstitial water ,as well as the correlation between these four components and COD ,TN and TP .The results showed that the position and intensity of the characteristic fluorescence peak center changed significantly before and after sewage treatment ,indicating that the relative composition and content of the organic wastewater varied with wastewater treatment .Furthermore ,the test results pres‐ented that humic‐like composition was not degraded significantly ,while protein‐like composition was degraded significantly .And the protein‐like component and COD ,TN and TP presented significant positive correlation .This paper analyzed the fluorescence characteristics changes of dissolved organic matter in sewage treatment by using three‐dimensional fluorescence spectrometry , and discussed the feasibility of three‐dimensional fluorescence technique applied for description of dissolved organic pollutant deg‐radation rule in the wastewater treatment process .
