Novel efficient sludge curing agent prepared from ardealite solid waste and preparation method thereof
The invention belongs to the technical field of ardealite solid waste recycling, and particularly relates to a novel efficient sludge curing agent prepared from ardealite solid waste and a preparation method thereof. The sludge curing agent is prepared from the following raw materials in percentage by mass: 65.1% of phosphogypsum, 14.2% of quick lime, 14.2% of ordinary Portland cement (P.O42.5), 2% of fly ash, 3% of an adsorbent, 1% of a mineralizer, 0.07% of an accelerator, 0.07% of a water reducing agent and 0.36% of triethanolamine. The production difficulty is low, the production cost is low, and the prepared curing agent has a good curing effect on sludge.
本发明属于磷石膏固废物再生利用技术领域，具体的说是一种磷石膏固废物制取新型高效污泥固化剂及制备方法，污泥固化剂由以下质量百分比的原料组成：磷石膏65.1％、生石灰14.2％、普通硅酸盐水泥(P.O42.5)14.2％、粉煤灰2％、吸附剂3％、矿化剂1％、速凝剂0.07％、减水剂0.07％、三乙醇胺0.36％；本发明的生产难度低，生产成本低，同时，制备得到的固化剂对污泥的固化效果好。
