摘要
以生活垃圾焚烧飞灰、工业污泥、污染土及黏土为原料进行了 5个配比方案的陶粒烧制研究.结果显示,当飞灰、工业污泥、污染土、黏土质量比为2∶3∶1∶4时,可烧制出堆积密度为693.9 kg/m3,筒压强度为5.48 MPa的陶粒.仅用飞灰和黏土烧制时,在飞灰、黏土质量比为7∶3的情况下,可烧制出堆积密度为859.5 kg/m3,筒压强度为12.97 MPa的陶粒.本次实验中5个配比方案烧制产物的可浸出重金属、二噁英、可溶性氯、硫化物和硫酸盐含量及放射性都能达到相关要求.
Abstract
In this study,five schemes were investigated for the sintering of ceramic pellets using fly ash from municipal solid waste incineration,industrial sludge,contaminated soil,and clay as raw materials.The results indicated that when the mass ratio of fly ash,industrial sludge,contaminated soil,and clay was adjusted to 2∶3∶1∶4,ceramic pellets with a bulk density of 693.9 kg/m3 and a cylinder strength of 5.48 MPa could be sintered.Alternatively,by solely utilizing fly ash and clay with a mass ratio of 7∶3,ceramic pellets exhibiting a bulk density of 859.5 kg/m3 and a cylinder compression strength of 12.97 MPa were achieved.In all five schemes,the leachable heavy metal,dioxins,soluble chlorine,sulfide and sulfate contents,as well as radioactivity of the ceramic pellets could meet the relevant requirements.
