A combined process of air flotation/iron carbon microelectrolysis /Fenton+ hydrolytic acidification +A/O+ contact oxidation is used to treat pesticide wastewater . The results show that,when the influent COD,NH3-N and toluene concentrations are 7 866,56 and 53 mg/L,the treated effluent COD,NH3-N and toluene concentrations are 435,13 and 0.4 mg/L,respectively. The average removal rates of COD,NH3-N and toluene were 94.5%,81% and 99.2%,respectively. The drainage index reached the Class B standard of Quality Standard for Sewage Discharge into Urban Sewers (GB/T 31962—2015),and the process efficiency was reliable,which can provide reference for the design and construction of similar pesticide wastewater treatment.
