摘　　要：针对草甘麟副产盐高磷、高氨氮、高TOC、有机物成分复杂等特点,通过含磷废盐固相临氧裂解有机污染物转化机制的研究,开发出晶体纯化一特种膜分离一高级氧化废盐除杂技术,建成了一套6万t/a废盐深度净化装置,成功地将草甘麟副产盐应用于离子膜法烧碱生产。In response to the characteristics of glyphosate by-product,such as high phosphorus,high ammonia nitrogen,high TOC and complex organic composition,a crystal purification,special membrane separation,advanced oxidation waste salt impurity removal technology has been developed through the study of the conversion mechanism of organic pollutants in phosphorus containing waste salt by solid-phase oxygen cracking.A 60-kt/a waste salt deep purification device has been built.Through the above scheme,glyphosate by-product salt has been successfully applied to the production of ion exchange membrane caustic soda.
