摘要
在室内自然风干条件下,对石灰、水泥、飞灰和淤泥4种添加剂不同添加量水平进行了正交试验研究,以期达到污泥在垃圾填埋场中的资源化利用。在养护3d时,7号试样(石灰:水泥:淤泥:飞灰:污泥=15:5:70:10:100)的强度和渗透性能基本满足填埋场覆盖材料的要求,是作为填埋场覆盖材料的较好方案。
Under the indoor natural air-dry condition, this study tested four additives (lime, cement, sludge) at different levels with an orthogonal experiment to achieve the resource utilization for landfill On the third day, the best proportional mixture of lime: eement:silt:fly:ash:sludge=15:5:70:10:100 was meet the requirement of strength and permeability of cover material for landfill.
