Abstract

The treatment of high concentration organic wastewater by microwave Fenton process was studied in this paper. The input volume of Fenton reagent, microwave power, reaction time, initial pH value is investigated to study the impact of the effect of the high concentration organic wastewater treatment. The optimum condition of Microwave-Fenton oxidation is: the pH reaching 3, Fenton reagent composition ratio of n(H2O2):n(Fe2+) being 75:1, the volume ratio of Fenton reagent and waste water being 1:10, the microwave power reaching 640W, accompanied by medium speed magnetic stirring, microwave irradiation time reaching 10min. The removal rate of COD is 83.05%, the removal rate of colority reached 100%.
