All-solid waste sludge curing and stabilizing composite material as well as preparation method and application thereof
In order to solve the technical problems of large raw material addition amount, high cost, long maintenance period and the like in the existing sludge solidification and stabilization treatment technology, the invention provides an all-solid waste sludge solidification and stabilization composite material as well as a preparation method and application thereof. The invention provides an all-solid waste sludge solidification and stabilization composite material, which comprises a sludge solidification material A and a sludge solidification material B. The sludge solidification material A comprises titanium gypsum, red mud and steel slag; the sludge curing material B is prepared from desulfurized fly ash and fly ash; the mass percent of each substance of the sludge curing material A and the sludge curing material B is as follows: 5 to 30 percent of desulfurized fly ash, 10 to 60 percent of fly ash, 5 to 25 percent of titanium gypsum, 5 to 10 percent of red mud and 10 to 25 percent of steel slag. All the raw materials of the prepared sludge solidification and stabilization composite material are formed by utilizing industrial solid wastes, and solidification and stabilization treatment can be carried out on the sludge in a short time.
为解决现有污泥固化稳定化处理技术存在的原材料加入量大、成本高、养护周期长等技术问题，本发明提供一种全固废污泥固化稳定复合材料及其制备方法和应用。本发明提供一种全固废污泥固化稳定复合材料，包括污泥固化材料A和污泥固化材料B，所述材料污泥固化A为钛石膏、赤泥、钢渣；污泥固化材料B为：脱硫灰，粉煤灰，污泥固化材料A、B各物质的质量百分比为：脱硫灰5‑30％、粉煤灰10‑60％、钛石膏5‑25％、赤泥5‑10％、钢渣10‑25％。本发明所制备的污泥固化稳定复合材料所有原料都是利用工业固废构成，能在短时间内对污泥进行固化稳定化处置。
