Ardealite harmlessly treated as ecological restoration material and method
The invention discloses an ecological restoration material prepared from phosphogypsum through innocent treatment and a method. The ecological restoration material is prepared from the following raw materials in parts by weight: 5-10 parts of lime milk, 0.01-0.05 part of a water reducing agent and 0.01-0.05 part of a dispersing agent. The method is realized through chemical reaction, even if soluble phosphorus and fluorine in the phosphogypsum form insoluble compounds to passivate the phosphogypsum, the phosphogypsum can be used for ecological restoration if miscellaneous fill is needed for leveling terraces of concave terrains in building construction and earth surface backfill lamps are needed for open-cast mining, so that the phosphogypsum is harmless to the environment and has no pollution to the environment. The added water reducer can enhance the fluidity and play a role in lubrication, the dispersant can enhance the capacity of the particles and reduce the time and energy required for completing the dispersion process, and after the phosphogypsum is modified, the phosphogypsum is harmless and can be used as a filling material for ecological restoration; the problems of environmental influence caused by no repair after mining of various mines and natural disasters of landslide are solved.
本发明公开了一种磷石膏无害化处理作为生态修复材料及方法，包括以下重量份数的原料：石灰乳5‑10份，减水剂0.01‑0.05份，分散剂0.01‑0.05份。本发明通过化学反应实现的，即使磷石膏中的可溶磷、氟形成难溶化合物使其钝化，可用于建筑施工下凹地形的地坪平整需要杂填土、露天采矿需要地表回填料灯，即可用做生态修复，从而对环境无害，加入的减水剂能增强流动性并起到润滑的作用，分散剂能增强颗粒的能力，减少完成分散过程所需要的时间和能量，通过对磷石膏进行改性后，可达到无害并可作为生态修复的填充材料，解决了各类矿山开采后无修复带来的环境影响及山体滑坡的自然灾害。
