摘要

近年来废岩棉的数量越来越多，已成为工业垃圾的处理难题，且目前还没有完善的处理方案，大多数废岩棉没有得到很好的处理，故通过实验研究来获取一种废岩棉的处理方法.观察废岩棉在不同温度下的状态，对燃烧后的废岩棉进行化学成分分析和矿物分析，再对废岩棉燃烧后的体积变化量进行计算.研究结果表明：燃烧后的废岩棉主要成分为CaO、SiO₂、Al₂O₃、MgO和Fe₂O₃，这五种主要成分对环境都是无毒无害的，不会对环境造成污染；燃烧后的废岩棉体积平均减少85.25%；通过观察不同温度下废岩棉燃烧产物的状态和XRD曲线，发现当温度为1 100 ℃时，废岩棉燃烧得较充分，所以在1 100 ℃下燃烧处理废岩棉很好地解决了废岩棉浪费土地资源、污染土地和环境的难题.

废岩棉工业垃圾污染环境燃烧处理

Abstract:

In recent years,there are more and more waste rock wool,which has become a difficult problem in the treatment of industrial waste.At present,there is no perfect treatment scheme,and most of the waste rock wool has not been well treated.Therefore,this paper intends to obtain a treatment method of waste rock wool by observing the state of waste rock wool at different temperatures and chemical formation of waste rock wool after heating.The results showed that the main components of waste rock wool after combustion are CaO,SiO₂,Al₂O₃,MgO and Fe₂O₃,which are non-toxic and harmless to the environment and will not cause pollution to the environment.The average volume reduction of waste rock wool after combustion could reach 85.25%.By observing the combustion products of waste rockwool at different temperatures,it was found that when the heating temperature of rock wool was 1 100 ℃,the waste rock wool was fully burned.Therefore,the waste rock wool could be burned at 1 100 ℃ to solve the problem of waste rock wool waste land resources,land and environment pollution.
