摘　　要：该文通过填装粒子电极的三维电极反应器对水中敌敌畏、乐果的农药污染物进行了催化降解过程的研究。通过三维荧光光谱,探讨了单一污染物、混合污染物及进水p H等影响因素对两种农药有效成分的去除效果。结果表明三维荧光光谱可以很好地监测反应过程中有机物的变化规律,通过三维荧光光谱可以直观地了解水中有机污染物降解过程中主要污染物的浓度变化、反应程度、反应产物类型等各类信息。三维荧光光谱法能很好地应用于水中有机农药的监测。The catalytic degradation processes with organic pollutants contained dichlorvos and dimethoate in water were investigated by three-dimensional electrode reactor filled with particle electrode. Three-dimensional fluorescence spectra method was used to explore the type of pollutant,pH value and other influence factors on the pesticide removal. The experimental results show that three-dimensional fluorescence spectra can monitor the reaction process perfectly. The change of pollutants such as concentration,extent of reaction,reaction product type, and other changeable information can easily be monitored. Three-dimensional fluorescence spectroscopy method can be well applied to water quality monitoring of organic pesticide.
