Abstract
In the paper, the treatment of the landfill leachate from Chongqing landfill by Fenton process was studied. Response surface methodology (RSM) and Box-Behnken central design had been applied to describe and optimize chemical oxygen demand (COD) removal efficiency of landfill leachate treatment using pH value, H2O2 dosage and FeSO4·7H2O dosage by Fenton process. The mutual interactions between three independent variables, viz. pH value, H2O2 dosage and FeSO4·7H2O dosage were obtained. The results revealed that the most influential variable under selected reaction conditions were pH value. The optimized conditions for landfill leachate treatment were as follows: pH value of 3.2, H2O2 dosage of 1.1 % and FeSO4·7H2O dosage of 0.4 %. Under these conditions, the maximum chemical oxygen demand removal efficiency of 59.1 % was achieved. This experimental value was in a good agreement with predicted one, which proved the validity of the model. Chemical oxygen demand analysis showed the landfill leachate could be effectively chemical oxygen demand removal by Fenton process.
