  • The high-concentration wastewater from acrylonitrile industries was treated with the combined processes of flocculation,adsorption oxidation,nanofiltration and adsorption. The effects and costs are investigated.The outcome shows that after the treatment with flocculation-nanofiltration-adsorption oxidation process,COD in the effluent decreases to less than 1 000 mg/L,the amount of ammonia nitrogen reduces to less than 25 mg/L, the amount of CN- drops below 5 mg/L, meeting the emission standard of the acrylonitrile industries. In addition, operating costs are moderate, which also lay a solid technical base for the circulating utilization of the wastewater from acrylonitrile industries.
