摘要
生活垃圾焚烧飞灰属于危险废弃物,目前采用的水泥+螯合剂稳定化处理后送填埋场处置的方法仍然需要大量的土地。本文主要针对利用减容化、无害化的生活垃圾处理方法后,针对存在的飞灰物质以及含有溶解盐、有毒及有害的重金属残留物质的特性和危害性进行深入的分析和探讨,并提出应用电动技术去除飞灰和残留的重金属物质,与此同时,提出电动去除技术的强化策略。
Fly ash from municipal solid waste incineration belongs to dangerous waste. At present, the stabilization method of cement and chelating agent is still needed a lot of land for landfill disposal. In this paper, the characteristics and hazards of fly ash and heavy metal residues containing dissolved salts, toxic and harmful substances are analyzed and discussed in depth after using volume reduction and harmless treatment methods of domestic refuse, and the application of electric technology to remove fly ash and heavy metal residues is proposed. At the same time, the strengthening strategy of electric removal technology is put forward.
