生活垃圾热解气化污染物产生与排放控制技术综述

近年来,农村生活垃圾热解气化炉正在我国部分山区大量使用,实际运行过程中污染物并未得到有效的控制,易导致严重的二次污染。重点介绍垃圾热解气化过程氮、硫、氯、重金属元素的迁移转化机制以及二英形成机理,并总结了不同污染物相应的排放控制措施,对垃圾热解气化污染的排放控制研究进行了展望。

The pyrolysis-gasification furnace for disposing rural domestic solid waste is being widely used in some mountainous areas of China in recent years.However,pollutants produced in the process of solid waste pyrolysis-gasification have not been effectively controlled in the actual engineering,which could lead to serious secondary pollution.The migration and transformation mechanisms of nitrogen,sulfur,chlorine and heavy metals contained the solid waste,and the formation mechanism of dioxins are mainly introduced during the pyrolysis-gasification process of solid waste.Importantly,the emission control technologies of different pollutants are also summarized in detail.Finally,the research on the emission control of waste pyrolysis-gasification pollution is prospected.
