垃圾焚烧飞灰的固定化技术概况

在我国采用焚烧法处理生活垃圾呈增长的趋势,如何处理焚烧过程产生的飞灰业已成为受人关注的问题。目前国外采用水泥固化、沥青固化、飞灰热处理(熔融及烧结)、化学药剂固化等方法对其进行无害化处理,经固定化处理后的飞灰可进入填埋或进行资源化利用。这些方法对我国的从业者具有一定的参考作用。此文介绍了国内外飞灰处理的研究进展。

Overview of Solidification Technology of Solid Waste Incineration Fly Ash

Incineration to treat the solid waste (SW) is increasingly used in China nowadays. It becomes a noteworthy problem how to dispose of fly ash. This paper introduces the currently used methods to treat solid wastes abroad such as cement solidification, asphalt solidification, fly ash thermo - treatment, chemical solidification. The solidified fly ash can be filled in land or be utilized as resources. These methods may be some help to the practitioners of fly ash treatment in China. What's more, the condition of the study in fly ash treatment at home and abroad is also presented.
