Microbial carbon sequestration reinforcement and mine filling utilization method of urban solid waste recycled aggregate
The invention discloses a microbial carbon sequestration reinforcement and mine filling utilization method of urban solid waste recycled aggregate, which comprises the following steps: step S1, fully mixing a microbial bacterial solution, a pH buffer solution and a calcium source solution with the urban solid waste recycled aggregate by adopting a soaking method or a spraying method to obtain mixed recycled aggregate; s2, putting the mixed recycled aggregate obtained in the step S1 into a carbonization test box for carbon sequestration strengthening treatment to obtain strengthened recycled aggregate; s3, fully mixing the reinforced recycled aggregate obtained in the step S2 with a gelling agent and water to obtain a filling material; and S4, filling the filling material obtained in the step S3 into the goaf through a filling pipeline. According to the invention, the problems of high water absorption and low density of the urban construction waste recycled aggregate are effectively improved, and the conveying performance and mechanical property of the filling material prepared from the recycled aggregate are improved, so that the filling material can be better suitable for coal mine cemented filling, urban solid wastes are treated, and a solution is provided for the problem of insufficient coal mine filling aggregate.
本发明公开了一种城市固废再生骨料的微生物固碳强化及矿山充填利用方法，包括以下步骤：步骤S1，采用浸泡法或喷洒法将微生物菌液、pH缓冲液和钙源溶液与城市固废再生骨料充分混合，得到混合再生骨料；步骤S2，将步骤S1得到的混合再生骨料放入碳化试验箱中进行固碳强化处理，得到强化再生骨料；步骤S3，将步骤S2得到的强化再生骨料与胶凝剂、水充分拌合，得到充填材料；步骤S4，将步骤S3得到的充填材料通过充填管路充填至采空区。本发明有效改善了城市建筑垃圾再生骨料吸水率高、密度低的问题，改善再生骨料制备充填材料的输送性能和力学性能，使之能更好适用于煤矿胶结充填，既处理了城市固废，又为煤矿充填骨料不足的问题提供了解决途径。
