Heavy metal polluted bottom mud efficient curing material prepared based on coal-based solid waste
The invention discloses a heavy metal polluted bottom mud efficient curing material prepared based on coal-based solid waste. The heavy metal polluted bottom mud efficient curing material comprises coal-based solid waste powder, calcium oxide, a composite activator and water, wherein the composite activator comprises sodium silicate and potassium hydroxide, the modulus of sodium silicate is 1-1.05, and the mass ratio of sodium silicate to potassium hydroxide is 4: 1. The raw materials are solid wastes, the price is low, and the source is wide; and the coal-based solid waste is consumed, occupied land resources are reduced while the national expenditure for treating the coal-based solid waste is reduced, and good environmental protection benefits are achieved. According to the invention, the heavy metal polluted bottom mud can be effectively solidified, meanwhile, the activity of heavy metal in the bottom mud is reduced, the solidified bottom mud is harmless, and resource utilization can be achieved.
本发明公开了一种基于煤基固废制备的重金属污染底泥高效固化材料，包括煤基固废粉末、氧化钙、复合激发剂和水；复合激发剂包括：水玻璃和氢氧化钾，水玻璃模数为1‑1.05之间，水玻璃与氢氧化钾的质量比为4:1。本发明的原料为固体废弃物，价格低廉，来源广泛；既消耗了煤基固废，减少国家处理煤基固废的耗资同时降低占用的土地资源，具有良好的环保效益。本发明可以有效固化重金属污染的底泥，同时降低底泥中重金属活性，使固化后底泥无害化，并可以资源化利用。
