Microorganism-multisource solid waste-based aggregate for industrial flue gas carbon sequestration and preparation method thereof
The invention belongs to the technical field of solid waste resource utilization and dual carbon, and relates to a microorganism-multi-source solid waste-based aggregate for industrial flue gas carbon sequestration and a preparation method thereof. The preparation method comprises the following steps: drying and ball-milling sulfuric acid slag and/or phosphorus sludge to obtain powder, uniformly mixing the powder, an alkali activator and microbial powder, adding water, granulating to obtain a modified aggregate biscuit, and culturing and maintaining the modified aggregate biscuit at the temperature of 20-60 DEG C; placing the cultured and cured modified aggregate biscuit in CO2-containing industrial flue gas, and performing mineralization curing at the temperature of 80-200 DEG C to obtain the aggregate; the microbial powder is ammoniated hot vibrio. The prepared aggregate has excellent compressive strength, solid waste resource utilization and efficient CO2 absorption can be achieved at the same time in the preparation process, and the aggregate has the advantages of being high in carbon sequestration efficiency and short in production period.
本发明属于固废资源化利用和双碳技术领域，涉及用于工业烟气固碳的微生物‑多源固废基骨料及制备方法。将硫酸渣和/或磷泥干燥、球磨获得粉料，将所述粉料、碱激发剂及微生物菌粉混合均匀，然后加水进行造粒获得改性骨料素坯，将改性骨料素坯在20～60℃的温度条件下进行培养养护；将培养养护后的改性骨料素坯置于含CO2的工业烟气中，在80～200℃的温度条件下进行矿化养护，即得骨料；微生物菌粉为氨化热弧菌。本发明制备的骨料具有优异的抗压强度，在制备过程中能够同时实现固废资源化利用及高效吸收CO2，具有固碳效率高、生产周期短有优势。
