城市生活垃圾焚烧飞灰在资源化利用方面的综述

The Overview of Municipal Solid Waste Incineration(MSWI)Fly Ash in Resources Utilization

城市生活垃圾焚烧技术具有无害化、减量化、资源化的优点,焚烧技术产生的飞灰属于危险废物。飞灰的处置方式有固化稳定化、化学处理法、安全填埋法、资源化利用法这五大类。本文通过阐述了飞灰在水泥、混凝土、沥青胶浆、微晶玻璃、陶瓷的资源化利用,对比分析以上利用途径的特点,总结出现阶段飞灰资源化利用的特点。

Harmless,reduction and resource utilization are the advantages of municipal solid waste incineration(MSWI),and the MSWI fly ash is the by-product,which is the category of hazard waste.The disposal method of fly ash are solidification/stabilization,chemical treatment,safe landfill and resource utilization.This paper compared the distinguishing features among four resource utilization ways that include cement,concrete,glass-ceramics,and ceramics,and this paper also include the shortage in resource utilization.
