含氰废水处理方法综述

Summary of cyanide containing wastewater treatment

在我国,含氰废水必须经过严格处理,以达到国家规定的排放标准。介绍了酸化回收法、硫酸亚铁法、氯氧化法、二氧化硫-空气氧化法、过氧化氢氧化法、电解法、臭氧氧化法、微生物法等。结合各方法的特点,推荐了不同含氰废水适合的处理方法。

In China,cyanide containing wastewater must be strictly treated to meet the national emission standards.This paper describes acidizing recovery method,ferrous sulfate method,chlorine oxidation process,SO2/air oxidation method,hydrogen peroxide oxidation process,electrolysis,ozone oxidation method,microbiological method.By combining the characteristics of each method,suitable treatment method for different cyanide containing wastewater is recommended.
