摘要: 采用多相混溶气浮技术+AAO生化处理+臭氧催化氧化+双膜(超滤+反渗透)集成技术对焦化废水进行处理,通过分段控制达标的方法,实现废水处理零稀释。处理后清水回用,浓水送高炉冲渣,不增加新水消耗,无外排水,节约水资源。

Abstract:

The integrated technology of multiphase miscible nano air flotation enhanced flocculation+AAO biological treatment+ozonation+double membrane(ultrafiltration+reverse osmosis)is adopted to treat coking wastewater by method of sectional control so as to realize zero dilution of wastewater treatment.The concentrated water is sent to the blast furnace for slag washing,without additional fresh water and without external drainage so that water resources can be saved.

Key words: Coking wastewater, Water treatment, Zero dilution
