High-water-content sludge curing agent and application method thereof
The invention relates to a high-water-content sludge curing agent and an application method, raw materials for forming the curing agent are simple, the curing agent comprises cationic polyacrylamide, super absorbent polymer SAP and ordinary Portland cement, and the mass ratio of the cationic polyacrylamide to the super absorbent polymer SAP to the ordinary Portland cement is (0.3-0.5): (0.8-1.0): (80-100); according to the method, fine sludge particles in the slurry are gathered into large gelatinous virtual bodies through the synergistic effect of cationic polyacrylamide and super absorbent polymer SAP particles, the large gelatinous virtual bodies are deposited to the bottom of the slurry under the action of self weight, mud-water separation is achieved, meanwhile, ordinary Portland cement and sludge are subjected to a hydration reaction, soil particles are bonded into blocks, and the mud-water separation effect is achieved. The porosity is reduced, and the strength is increased, so that the curing utilization of the high-water-content sludge is realized.
本发明涉及一种高含水率淤泥固化剂及应用方法，构成固化剂的原材料简单，包括阳离子聚丙烯酰胺、高分子吸水树脂SAP和普通硅酸盐水泥，其中，阳离子聚丙烯酰胺、高分子吸水树脂SAP和普通硅酸盐水泥的质量比为（0.3‑0.5）:（0.8‑1.0）:（80‑100）；通过阳离子聚丙烯酰胺和高分子吸水树脂SAP颗粒的协同配合作用，将泥浆中的细小淤泥颗粒聚成大型凝胶状虚体，在自重的作用下沉积到泥浆的底部，实现泥水分离，与此同时，普通硅酸盐水泥与淤泥发生水化反应，土颗粒粘结成块，孔隙率减小，强度增加,从而实现对高含水率淤泥的固化利用。
