Method for preparing biobrick by using microorganisms to induce calcium carbonate precipitation and solidify rare earth tailing sand
The invention discloses a method for preparing a biobrick by using microorganisms to induce calcium carbonate precipitation and solidify rare earth tailing sand, and belongs to the field of geotechnical engineering. The method comprises the following steps: treating the rare earth tailing sand; the preparation of the curing liquid comprises preparation of a bacterial liquid and a cementing liquid; and manufacturing the biobrick. The biobrick is manufactured in a slurry mixing and demolding mode, the process is simple, the cost is low, the manufacturing process is green and free of pollution, the prepared biobrick can meet the requirement for temporary storage of the rare earth tailing sand, the environmental problem caused by accumulation of the rare earth tailing sand is solved, and a foundation is laid for secondary recycling of the rare earth tailing sand.
本发明公开了一种微生物诱导碳酸钙沉淀固化稀土尾矿砂制备生物砖的方法，属于岩土工程领域。该方法包括以下步骤：稀土尾矿砂的处理；固化液的制备包括菌液、胶结液的制备；生物砖制作。本发明制作生物砖采用拌浆脱模的方式，工艺简单、成本低，制作过程绿色无污染，制备的生物砖能解决稀土尾矿砂暂存的要求，既解决了稀土尾矿砂的堆积造成的环境问题，也为稀土尾矿砂的二次回收利用打下了基础。
