超滤+反渗透处理印染废水技术特点是什么?

纺织印染行业是我国工业的重要组成部分,废水量大,约占工业废水排放量的35%。印染废水水量大、有机污染物含量高、碱度和pH值变化大、水质变化大;可生化性能差,废水BOD5/COD值一般在20%左右;色度高,有时可达4000倍以上;印染行业中,PVA浆料和新型助剂的使用,使难生化降解的有机物在废水中的含量大大增加。

  2 膜工艺在印染废水处理中的应用


  针对印染废水处理体育外围投注属于典型的工业有机废水这一特性和可生化性较差并含有难以降解的水溶性有机污染物、SS、胶体状物质等特点,采用了“双膜法”处理工艺,不仅可以回收水资源,实现废水循环回用,而且还可以进一步削减排污总量。
