含氰废水对生物和环境危害极大，其排放标准越来越严格。介绍了铁碳微电解法降解含氰废水工艺，考察了Fe-C@CNTs球团、Fe-C球团与铁屑对含氰废水降解率的影响，实验结果表明Fe-C@CNTs球团处理含氰废水更为高效。Fe-C@CNTs球团处理含氰废水时最佳质量浓度为100 g/L、最佳反应时间为40 min，在此条件下，Fe-C@CNTs球团对含氰废水的降解率高达83.3%。

Cyanide-containing wastewater is very harmful to biology and environment,and the corresponding emission standard is stricter and stricter.This paper introduces the degradation of cyanide-containing wastewater by iron-carbon micro-electrolysis.The degradation rates of cyanide-containing wastewater by Fe-C@CNTs pellets,Fe-C pellets and iron scraps are compared.Experimental results show that Fe-C@CNTs pellets are more efficient in treating cyanide-containing wastewater than other two materials.The optimum dosage and optimum reaction time of Fe-C@CNTs pellets for treating cyanide-containing wastewater is 100 g·L^-1 and 40 minutes,respectively.Under these conditions,the degradation rate of cyanide containing wastewater by Fe-C@CNTs pellets is as high as 83.3%.
