摘要
由于具有无害化、减量化和资源化三个方面的显著优势,垃圾的焚烧处理技术近年来已成为国内外垃圾无害化处理研究领域的热点。但是垃圾焚烧中的重金属会对环境造成二次污染,对垃圾焚烧烟气中的汞,铅,镉的存在形态及影响它们去除率的主要因素进行了分析,基于垃圾焚烧过程中烟气净化的基本流程,指出利用现有烟气净化设备共同除汞,铅,镉的可行性;较为详细的论述了各种重金属排放控制技术的研究进展。并对同时脱除汞,铅,镉技术的研究趋势进行了展望。
MSW incineration becomes the main method for at home and abroad in recent years it could better realize the reducing of volume,keeping harmless and turning to resources.But heavy metal which is created in the process of MSW incineration will cause the secondary pollution to the environment.Article illustrates the existent state of mercury,lead and cadmium and the main factors which affect the elimination rate of the three kinds of heavy metals.Through the introduction of the air Pollution control devices（APCDs）,it points out that synergistic control is feasible,taking advantage of existing APCDs.The latest research progress of mercury,lead and cadmium emission control is summarized.Future research directions are suggested.
