采用几种不同厂家提供的有机重金属飞灰螯合剂和一种无机飞灰稳定剂对湖北某垃圾焚烧厂及四川某垃圾焚烧厂所产飞灰分别进行了稳定化处理的研究。结果表明,就2种飞灰而言,有机螯合剂在处理效果上较无机药剂具有一定的优势,为使飞灰处理后的浸出毒性低于《生活垃圾填埋场污染控制标准》(GB16889-2008)所规定的限值,满足进入垃圾填埋场分区填埋的要求,不同种类的有机螯合剂添加量在1% ~ 5%之间,各有机螯合剂的稳定效果与其分子结构和分子大小的关系密切。而某无机药剂在添加剂量为15%时仅能使四川某厂所产生的飞灰勉强达标。从经济上考虑,使用有机螯合剂的药剂成本费用也低于某无机药剂,同时对比实...

The stabilization treatment of fly ash produced by waste incineration plant from Hubei and Sichuan was studied by using different agents, which were 3 kinds of heavy metal chelating agents and an inorganic ash stabilizer provided by different manufacturers. The results showed that organic chelatings had certain advantages compared to inorganic agents. When different types of organic chelators were added with an amount between 1% to 5%, the two fly ash handling toxic leaching was below the “Landfill Pollution Control Standards” (GB16889-2008) ...
