摘要
采用臭氧对活性染料废水生化处理出水进行脱色深度处理,对比考察了臭氧射流曝气工艺和传统微孔曝气臭氧氧化工艺的处理效果。结果表明,臭氧射流曝气工艺对废水COD、色度、氨氮的去除率分别为51%、97%和71%,相对使用传统微孔曝气臭氧氧化工艺,臭氧射流曝气工艺具有停留时间短,能耗低,臭氧利用率高等优势,是一种非常适合染料废水深度处理的工艺。
We use ozone to conduct deep biochemical effluent-bleaching treatment of active dyes. By comparison we examine the both effects of ozone j et-aeration technology and traditional micro-porous aeration ozone-oxidation processing technology.Results indicate that by ozone j et aeration technology,removal rates of wastewater COD,color,ammonia and nitrogen are respectively 5 1%, 97% and 71%,by contrast with conventional micro-porous aeration ozone oxidation process,ozone j et aeration processing has advantages of a short residence time,low energy consumption with a high ozone utilization rate which is considered as a very practical deep dye wastewater processing.
