| 摘 要： | 监控污水偷排以及诊断污染类型是当前水质预警研究的重点问题.由于污染物种类和含量各异,污水的荧光光谱与水样一一对应,被称为污水的"荧光指纹".以两种城市污水为例,探索了利用荧光指纹参数区分污水的可行性.两种城市污水荧光指纹特征的主要差异在于:A厂污水最强荧光峰强度(I280/340)平均为8308±1560,次强荧光峰强度(I225/340)平均为6350±1173;B厂污水I280/340平均为5929±400,I225/340平均为4224±90;平均最强和次强荧光峰强度之比分别为1.31和1.41.荧光指纹特征可以区分这两种城市污水的差异.

| Abstract: | Monitoring of wastewater discharge and diagnosis of pollution pattern are key problems in water quality prewarning.Because of differences of pollutants and their concentration,fluorescence spectrum is unique for each sample,named "fluorescence fingerprint".The possibility to identify wastewater by fluorescence fingerprint parameters was investigated in the case of municipal wastewater from two plants.The major differences of municipal wastewater from two plants included that average fluorescence intensities... |
