Degradating Organophosphosphous Pesticides Wastewater by Sonophotocatalytic Oxidation Technology

Abstract

Organophosphosphous pesticides wastewater was degradated by sonophotocatalytic oxidation technology,and some factors affecting sonophotocatalytic oxidation reaction were studied in details such as different degradation modes,the time of degradation、initial solution concentration 、initial pH value、the amount of catalyst and the effect of Fenton,etc.In the end the optimal conditons were determined.The conclusion we drawed was that the optimal time of degradation was 100min 、initial solution concentration was 100mg／L、initial pH value was 7、the amount of catalyst was 0.6g,moreover the adding of Fenton could greatly enhance the degradation rate.
