摘要
对采用焦亚硫酸钠/空气法处理含氰电镀废水进行了试验研究。结果表明,在pH为10.0,焦亚硫酸钠投加量为CN-质量的7.5倍,曝气量为300 L/min的条件下,处理60 min后的废水中总氰化物浓度低于0.3mg/L,具有较好的除氰效果。
This article gives a description of treating electroplating wastewater containing cyanide by Na2S2O 5/Air method. The research results showed that, under the optimal condition that, the pH value was 10, the ratio of Na2S2O 5 to CN＇ was 7.5 to 1, the air provision was 300 L/min, the reaction time was 60 minutes, a desirable result was achieved that the cyanide mass concentration of treated electroplating wastewater containing cyanide was decreased to 0.3mg/ L .
