Solid-waste-based alkaline aggregate, preparation process thereof and application of solid-waste-based alkaline aggregate in acid wastewater treatment
The invention relates to the technical field of wastewater treatment, in particular to solid-waste-based alkaline aggregate as well as a preparation process and application thereof in acidic wastewater treatment.The solid-waste-based alkaline aggregate is prepared from the following raw materials: steel slag powder, desulfurized fly ash, red mud, a cementing material, carbide slag and water, the total proportion of the steel slag powder, the desulfurized fly ash and the red mud in the raw materials is 75-85%, the proportion of the cementing material in the raw materials is 5-15%, and the proportion of the carbide slag in the raw materials is 3-15%. The steel slag powder, the red mud, the desulfurized fly ash, the carbide slag, the cementing material and water are uniformly mixed and then prepared into the solid-waste-based alkaline aggregate through granulation equipment, so that alkaline substances can be released to neutralize acidic wastewater, and meanwhile, the situation that industrial waste residue powdery fine particles directly enter the wastewater to cause color change and turbidity of a water body and increase the sludge amount of a river bottom can be effectively avoided; the utilization of the steel slag, the desulfurized fly ash and the red mud in the field of wastewater treatment can be realized, and the resource utilization rate of the steel slag is improved.
本发明涉及废水处理技术领域，具体涉及一种固废基碱性骨料及其制备工艺和在酸性废水处理中的应用，该固废基碱性骨料包括以下原料：钢渣粉、脱硫灰、赤泥、胶结料、电石渣和水，其中，所述钢渣粉、所述脱硫灰和所述赤泥的总和在原料中的占比为75～85％，所述胶结料在原料中的占比为5～15％，所述电石渣在原料中的占比为3～15％。本发明将钢渣粉、赤泥、脱硫灰、电石渣、胶结料与水混合均匀后通过造粒设备制备成固废基碱性骨料，不仅可以释放出碱性物质中和酸性废水，同时可以有效避免工业废渣粉状细小颗粒直接进入废水中造成水体变色、混浊，增加河底的淤泥量，还可以实现了钢渣、脱硫灰、赤泥在废水治理领域的利用，提高钢渣的资源化利用率。
