摘　　要：本文以氰乙酸乙酯生产工艺中产生的含氰废渣为研究对象，提出了含氰废渣灼绕除氰反应机理，并据大量试验数据建立了氰化物残留率随反应时间变化的数学模型．本研究推荐采用高温灼烧除氰设计参数为：温度６００℃，时间６０ｍｉｎ．试验表明，高温灼烧除氰技术综合治理含氰废渣技术可行，效果好，能达到无氰化，且无二次污染．Based on the study of the waste containing cyanogen compound produced from the process of the making of cyanoacetlc etholin, the paper advances the mechanism of cyanogen removed by means of burning and puts forward a mathematic model of residual CN- rate at different time on the basis of a number of experimental data. The parameters suggested temperature is 600 degrees centigrade, time is 60 minutes. The results show the technique is practical and effectice with no second pollution.
