摘　　要：气化熔融技术处理后的灰渣中二恶英含量和重金属浸出毒性都符合相关标准。气化熔融技术可分为灰渣全熔融的气化熔融技术和飞灰熔融的气化熔融技术,其中飞灰熔融的气化熔融技术较适合处理低热值城市生活垃圾。垃圾成分不同,最佳气化温度也相应改变,根据不同地区垃圾成分的差异设定适合的气化温度、优化炉膛参数是非常有必要的。炉膛内加入SiO2和CaO可降低灰渣的熔融温度,增加重金属固化率。The dioxin contents and leaching toxicity of all heavy metals can reach the standard in slag, which is produced by gasification and melting treatment. Gasification and melting technology can be divided into two types, one is melting of slag and ash, another one is melting of ash. The ash melting technology is suitable for handling municipal solid waste with low calorific value. With different MSW compositions, the optimum gasification temperature is changed. It is necessary to choose suitable temperature and optimal furnace parameter, according to difference between MSW compositions in different regions. It can reduce melting temperature and increase SiO2 and CaO in furnace. solidification rate of heavy metals, when adding
