【摘要】 随着工业生产规模的不断扩大及淡水资源的日益匮乏,生产中产生的废水处理回用已经成为亟待解决的大问题。为了实现循环水的"零排放",采用超滤反渗透系统对冷却循环水进行除盐和除硬使之达到回用标准。该工艺对盐分去除和硬度去除均在98%以上,通过效益核算,结果表明投资回收期短,长期效益显著。更多还原

【Abstract】 With the constantly expanding production scale and the increasing scarcity of fresh water resources,production wastewater reuse has become the big problem that solves urgently.In order to realize the circulation water"zero emissions",using UF-RO system of circulating cooling water for removing salt and hardness to reach the level of reuse.The process of salt removal and hardness removal in 98%,through the benefit calculation,the results show that the investment recovery period is short,long term benefit.更多还原
