摘要
通过化学絮凝-生物接触氧化对西北某毛纺厂2 600 m3/d印染废水进行了二级处理,处理后的水达到了国家规定的排放标准。其中50%处理后的废水再经臭氧氧化脱色三级处理,其水质符合毛纺厂染整工艺规范要求,返回利用可以代替软化水使用。
By secondary treatment consisting of chemical flocculation and biomembrane oxidizing for the treatment of 2 600 m^3/d dyeing waste water in a woolen mill of Northwest China, the discharged water reaches the national primary discharge standard. After 50o/6o of the discharged water was treated by ozone decolourization （i. e. tertiary treatment）, the water quality accords with all technical criterion of woolen mill. So the treated water can substitute for the soft water and return to be used.
