采用Fenton、电-Fenton高级氧化技术降解水体OPEs(TCEP和TEP),通过系统实验和表观动力学方程的建立,比较、探讨Fenton、电-Fenton降解水体OPEs的特征.主要结论为:①在一定条件下,Fenton 氧化降解水中OPEs 的反应速率和OPEs、H2O2以及Fe2+的初始浓度均呈正相关关系;②水体中TEP的电-Fenton降解速率受电极初始电位、初始Fe2+浓度以及初始TEP浓度影响,其中电极电位对反应速率的影响更大;③与Fenton高级氧化技术相比,电-Fenton对有机物降解更彻底,且能耗低,但反应时间较长;④Fenton 降解水体 TCEP、TEP 和电-Fenton 降解水体 TEP 的表观动力学方程分别为 γ=100.2029P1.0599F1.4181H0.6736、γ=100.8177P1.0810F1.1551H0.5108、γ=10-1.0650P1.1138V1.7487.%Advanced oxidation technology like Fenton and EF-Fenton are used to remove organophosphate esters (OPEs), including TCEP and TEP,in water.A series of system experiments and the establishing of dynamical e-quations are for the purpose of finding out the characteristic of degradation of OPEs.The main conclusions are as follows:①Under certain conditions,it is obviously that the initial concentration of OPEs,H2O2and Fe2+all have a positive correlativity with the reaction rate of Fenton degrades OPEs in water;②The reaction rate of TEP in water by EF-Fenton process is influenced by initial electric potential and the concentration of Fe 2+, TEP.The electric potential has a greater influence; ③ Compared to ordinary Fenton advanced oxidation technology, EF-Fenton has merits like reacting more completely and low energy consumption,but the reaction time is longer;④The dynami-cal equations of TCEP, TEP in water by Fenton process and the TEP in water by EF-Fenton process are: γ=100.202 9P1.059 9F1.418 1H0.673 6,γ=100.817 7P1.081 0F1.155 1H0.510 8,γ=10 -1.065 0P1.113 8V1.748 7.
