含氰废水处理方法进展

Progress in the Treatment of Cyanide-contained Waste Water

综述了近年来国内外含氰废水回收与处理方法的最新研究进展。阐述了含氰废水处理方法———酸化回收法、膜分离技术、化学络合法、萃取法、自然降解法、化学氧化法、高温水解法、电解法、催化氧化法和微生物降解法的基本原理、优缺点和工程应用。指出含氰废水处理技术将向几种方法组合应用,"零排放"方向发展。

Recent progress in the treatment of cyanide-contained waste water was reviewed in the paper. The basic principle, application, advantage and disadvantage of the methods such as acidify recovery process, film method, chemical sedimentation process, exaction method, natural degradation, chemical and catalytic oxidation process, hydrolysis and electrolysis methods and microbiological degradation were introduced.
