Treatment of Acid Rose Red dyeing wastewater by integrated ozonization-biological aerated filter process
一体化臭氧-曝气生物滤池处理酸性玫瑰红印染模拟废水

Based on properties of Acid Rose Red dyeing wastewater with high chroma and difficult biodegradability,two kinds of processes of the integrated and the detached ozonization-biological aerated filter(O3-BAF) were used,respectively.Compared with the detached unit,the integrated one had a simultaneous synergy of ozonization and biological oxidation in one reactor,and it could lower the operation cost and the investment of construction.The experimental result showed that,the process of integrated ozonization-biological aerated filter was better than the detached unit,its removal efficiency of COD reached 60% and the efficiency of decolorization was 92%.The satisfied treatment result was got.
