Gelling agent for stabilizing and curing spoil pollutants as well as preparation method and use method of gelling agent
The invention discloses a gelling agent for stabilizing and curing spoil pollutants, which comprises the following components in parts by weight: 30-50 parts of coal gangue powder; 20-40 parts of slag powder; 20 to 40 parts of waste concrete recycled micro powder; 5-8 parts of sodium alginate; 10-15 parts of sodium silicate powder; 1-3 parts of polyvinyl alcohol; 0.3 to 0.5 part of a carbon oxide nanotube; 5 to 8 parts of chitosan; compared with the prior art, in-site rapid pollution remediation of the heavy metal spoil is achieved, environment pollution caused by accumulation of waste is avoided, and meanwhile resource saving and environment protection are facilitated after solid waste recycling; the synergistic powder capable of doubly adsorbing heavy metals and forming a dual cross-linked consolidation network is added, so that the adsorption and stability of pollutants and the soil solidification efficiency can be remarkably improved, and the strength and water stability of the formed solidified soil are enhanced.
本发明公开了一种用于弃土污染物稳定和固化的胶凝剂，以重量份数计，包括以下各组分：煤矸石粉30‑50份；矿渣粉20‑40份；废弃混凝土再生微粉20‑40份；海藻酸钠5‑8份；硅酸钠粉10‑15份；聚乙烯醇1‑3份；氧化碳纳米管0.3‑0.5份；壳聚糖5‑8份；本发明与现有技术相比，实现重金属弃土的场内快速污染修复，避免废弃物的堆积污染环境，同时固废资源化后有利于节约资源和保护环境；加入可双重吸附重金属和形成双重交联固结网络的协同粉剂，能够显著提高污染物的吸附、稳定和土壤固化效率，增强所形成的固化土的强度和水稳性。
