摘要: 研制了一种新型的光电催化反应器，并对PEG-2000模拟废水进行了降解动力学研究。结果表明，电解、光催化、光电催化去除0.5 g/L的PEG-2000模拟废水中COD为零级反应，从动力学角度来看，光电协同作用明显；在不同的外加偏压、初始pH值、曝气量和光强条件下，反应符合零级动力学规律；不同初始浓度PEG-2000模拟废水的光电催化反应具有不同的反应级数，高浓度时，此光电催化体系符合零级反应动力学规律，低浓度时，光电催化氧化符合一级反应动力学规律。

Abstract: new type of photoelectrocatalytic reactor was developed and the degradation kinetics of wastewater simulated by PEG-2000(0.5 g/L) was studied. The removal of COD from wastewater by electrolysis， photocatalysis and photoelectrocatalysis is zero-order reaction under different external bias， initial pH values， aeration and light intensity， and the reaction occur in the reactor has obvious photoelectric synergies in terms of kinetics. The photoelectrocatalytic reaction of different initial concentrations of wastewater simulated by PEG-2000 has different reaction orders which follows zero order kinetic law at high concentrations and first order kinetic law at low concentrations.
