Environment-friendly alkaline residue and sludge composite solidified soil with low chloride ion content
The invention discloses environment-friendly alkaline residue and sludge composite solidified soil with low chloride ion content. The formula comprises the following components in parts by weight: 35-40 parts of alkaline residues, 55-60 parts of sludge, 0.3-0.4 parts of an anion exchanger, 0.2-0.3 parts of a wrapping agent, 0.3-0.5 parts of a water absorbent, 0.1-0.2 parts of a dispersing agent, 2-3 parts of cement, 3-4 parts of lime, 2-3 parts of fly ash and 1-2 parts of gypsum. According to the invention, 201X7 strongly basic anion resin is used as an anion exchanger; diammonium phosphate and diatomite are used as wrapping agents; alkali residues are used as an alkali activator of a curing agent; under the condition of certain unconfined compressive strength, the environment-friendly solidified soil with low chloride ion content is prepared, the content of dissolved chloride ions is lower than that of original mud flat sludge, the problem that the concentration of the dissolved chloride ions in the alkaline residues is high and pollutes the environment is solved, resource utilization of the alkaline residues is achieved, environmental pollution is reduced, and economic, social and environmental benefits are obvious.
本发明公开了一种低氯离子含量环保型碱渣淤泥复合固化土，包括以下重量份数的配方成分：碱渣35‑40份、淤泥55‑60份、阴离子交换剂0.3‑0.4份、包裹剂0.2‑0.3份、吸水剂0.3‑0.5份、分散剂0.1‑0.2份、水泥2‑3份、石灰3‑4份、粉煤灰2‑3份、石膏1‑2份。本发明以201X7强碱性阴离子树脂作为阴离子交换剂，以磷酸二铵和硅藻土作为包裹剂，以碱渣作为固化剂的碱激发剂，在具有一定无侧限抗压强度的情况下，制备出了低氯离子含量的环保型固化土，溶解型氯离子含量低于原滩涂淤泥，解决了碱渣中溶解型氯离子浓度高污染环境的问题，实现了碱渣的资源化利用，减少环境污染，经济、社会、环境效益明显。
