商业洗衣店排放的废水中含有大量的 BOD、COD、洗涤剂和表面活性剂。为了减少废水的排放而不得不将一 部分废水回用,因此回用水中的上述污染物必须去除。厦门福美科技公司的膜分离设备,将纳滤和微滤设备结合在一起,能够将废水中油脂、TDS、 TSS,洗涤剂和表面活性剂去除,系统的渗透产水则被循环回洗衣工艺中使用。 系统设计:下图的一套洗衣店废水处理系统采用先微滤后纳滤的两级膜设计。其中微滤设备用于去除各种纤维、 油脂、污垢;而纳滤设备用于去除 TDS。洗涤剂和表面活性剂。微滤设备中有将近 50gpm 的浓水被循环回微 滤设备进口,其目的是为了提高微滤膜表面的切向流速以防止微滤膜表面污染。纳滤设备的渗透水被循环回洗衣工艺中。
