摘要
高盐化工废水通常具有较高的机污染物浓度和悬浮固体浓度,不仅处理成本高、处理难度大,且存在潜在的环境风险。相比其它传统的水处理技术,纳滤膜技术不仅对高盐化工废水的处理效果好,同时可以对污水中的有用物质进行资源回收,因此其在高盐化工废水处理的应用中具有独特的优势。本文综述了纳滤膜分离技术在印染、制药、农药等化工领域高盐废水处理中的研究现状,旨在进一步推动纳滤膜技术在高盐化工废水处理领域中的应用。
High-salinity wastewater is usually characterized with high concentration of organic pollutants and suspended solids, which not only need high treatment cost and difficult to deal with, but also bring about potential environmental risk. Compared with other traditional wastewater treatment technology, Nano-filter technology could ensure good treatment for high salt chemical wastewater and recover useful substances from it. Therefore, it owns a unique advantage in the application for high-salt chemical wastewater treatment. The application of Nano-filter technology in the treatment of high-salt wastewater in the fields of printing, dyeing, medicine and pesticide was reviewed in this paper, which was aimed to further promote the application of Nano-filter technology in the treatment of high-salt chemical wastewater.
