Biological curing agent based on multi-source solid waste and preparation method
The invention provides a biological curing agent based on multi-source solid waste and a preparation method thereof, and belongs to the field of building muck curing materials and preparation thereof. The method comprises the following steps: crushing and screening undisturbed coal gangue, calcining at high temperature, grinding and screening to obtain mechanically ground and thermally activated coal gangue powder; blast furnace slag powder, fly ash, coal cinder powder and mechanical grinding-thermal activation coal gangue powder are mixed in a dry state, and multi-source solid waste mixed powder is obtained; adding the multi-source solid waste mixed powder into the bacillus pasteurii liquid, stirring and adsorbing, and freeze-drying to obtain a multi-source solid waste bacterial adsorbent; calcium oxide, sodium sulfate, dihydrate gypsum and urea are mixed and dried to obtain a composite exciting agent, and the biological curing agent based on the multi-source solid waste comprises a multi-source solid waste bacterial adsorption body and the composite exciting agent. According to the method, resource utilization of a large amount of industrial solid waste is promoted, and the cured waste soil is high in strength and good in durability.
本发明提供了一种基于多源固废的生物固化剂及制备方法，属于建筑渣土固化材料及制备领域。所述方法包括：将原状煤矸石破碎筛分，高温煅烧，粉磨过筛，获得机械粉磨‑热活化煤矸石粉；将高炉矿渣粉、粉煤灰、煤渣粉、机械粉磨‑热活化煤矸石粉，在干燥状态下混合，获得多源固废混合粉体；将多源固废混合粉体加入巴氏芽孢杆菌菌液中，搅拌吸附后冷冻干燥，获得多源固废细菌吸附体；将氧化钙、硫酸钠、二水石膏和尿素混合，干燥后获得复合激发剂，所提供的基于多源固废的生物固化剂，包括多源固废细菌吸附体和复合激发剂。本发明促进了大宗工业固废的资源化利用，固化后的废弃土强度高、耐久性好。
