Treatment of pesticide wastewater by physicochemical pretreatment+ anaerobic+two-stage A/O process
After the physicochemical pretreatment process (electrochemical oxidation,ferric-carbon microelectrolysis) was used for the pretreatment of the wastewater with mixed high and medium concentrations,the anaerobic + two-stage A/O process has been used for the treatment of comprehensive wastewater.The designed treatment capacity is 300 m3/d.The operation results show that by physicochemical pretreatment the removing rate of COD could reach 32％,and the whole process treated effluent COD is lower than 500 mg/L,ammonia-nitrogen lower than 35 mg/L,and salinity lower than 0.6％.The water quality of the effluent can meet the take-over requirements.The effect of technological treatment is obvious.
