Environment-friendly composite industrial waste solidified sludge and preparation method thereof
The invention discloses environment-friendly composite industrial waste solidified sludge and a preparation method thereof. The environment-friendly composite industrial waste solidified sludge is prepared from the following raw materials in parts by weight: 6.5 to 8.0 parts of phosphogypsum, 7.4 to 9.0 parts of fly ash, 9.5 to 12.1 parts of furnace slag, 2.7 to 3.0 parts of calcium oxide, 3.0 to 3.4 parts of montmorillonite, 8.5 to 10.6 parts of ordinary Portland cement and 50.5 to 62.5 parts of sludge. The method is easy and convenient to operate and low in cost, a large amount of industrial waste can be recycled, the sludge subjected to curing treatment can be used for an engineering foundation on the spot, stockpiling of the sludge and industrial solid waste is greatly reduced, the multiple industrial waste is compounded for use, the mutual promotion effect of all the components is effectively utilized, the sludge strength is improved, and the construction cost is reduced. The sludge solidification treatment efficiency and the environmental safety are ensured.
本发明公开一种环保型复合工业废料固化淤泥及其制备方法，每100重量份的原料包括如下组分：磷石膏6.5～8.0份，粉煤灰7.4～9.0份，炉渣9.5～12.1份，氧化钙2.7～3.0份，蒙脱石3.0～3.4份，普通硅酸盐水泥8.5～10.6份，淤泥50.5～62.5份。本发明操作简便、成本低廉，能够大量回收利用工业废料，且经固化处理后的淤泥可就地用于工程基础，大量减少淤泥和工业固废的堆存，通过多种工业废料的复配使用，有效利用了各组分间的相互促进作用，提高了淤泥强度，保证了淤泥固化处理效率和环境安全性。
