Treatment of pesticide wastewater by moving-bed biofilm reactor combined with Fenton-coagulation pretreatment.

Abstract

In order to treat pesticide wastewater having high chemical oxygen demand (COD) value and poor biodegradability, Fenton-coagulation process was first used to reduce COD and improve biodegradability and then was followed by biological treatment. Optimal experimental conditions for the Fenton process were determined to be Fe(2+) concentration of 40 mmol/L and… (More)
