【摘要】 对试用过氧化氢法对含氰电镀废水酸化回收后进行二次处理的试验情况、处理原理、生产影响因素及安全操作等进行了探讨。近半年的生产应用情况表明,该法具有工艺操作简单、投资省、成本低等优点,能容易地将含氰(CN-)500mg/L的酸化回收尾液处理到0.5mg/L以下。更多还原

【Abstract】 A new technology is studied in treating waste water contained high concentration cyanide by hydrogen peroxide.The result of treating is that CN-- in waste water is reduced from 500mg/L to less than 0.5mg/L .This method in contrast to other method has advantage of easy operating, lower cost ,and so on.更多还原
