Study on the Treatment Technology of Methomyl Wastewater

Huiqin Li

Abstract

This paper reveals what happens when Fenton reagent oxidation was used in methomyl wastewater treatment. The effects of pH value, Fenton reagent dosage, and reaction time on the removal efficiency of CODCr were studied respectively .The result of Fenton reagent oxidation showed that when initial pH value was 3.5, reaction time was 2h,in addition to 4mL/L H2O2, 4g/L10% FeSO4,CODCr removal efficiency could reach 85%. after aerobic treatment,the water quality satisfied the standard of grade 1 in integrated wastewater discharge standard(GB8978-1996).
