超滤在制革废水处理中的应用

超滤作为一种高新技术,具有分离效率高、设备简单、操作方便、无相变和节约能源等方面的特点,使其在制革废水处理方面的应用具有很大的潜力。超滤独特的处理过程使制革废水中绝大部分物质可被回收和再利用。这将意味着在保护环境的同时,还可为生产单位节约成本,直接创造经济效益。着重介绍了超滤在单项制革废水和综合制革废水处理中的应用,并指出了在生产环节减少污染物、研究采用清洁生产工艺以及采用高新技术对制革废水进行处理是制革行业的发展方向。

Applications of Ultrafiltration in Disposal of Tannery Wastewater

Ultrafiltration,which is considered to be high-tech,has many advantag es such as high separation efficiency,simple facility,convenient operation,no phase change and saving energy,which makes it potential to dispose of tannery wastewater.Special disposal process of ultrafiltration makes most of pollutants in the tannery wastewater be recovered and reused.This means that it not only protects the environment but also saves production cost and creates economic ret urns directly.Its prospect is very bright.Applications of ultrafiltration in t he disposal of single and comprehensive wastewater from leather industry are int roduced with emphasis.The prospect of leather industry is pointed out,i.e.red ucing pollutant produced in manufacture process,adopting clean production techn ology and high-tech to deal with tannery wastewater.
