Inducer for inducing calcium carbonate to deposit and solidify aeolian sand through microorganisms and method for depositing and solidifying aeolian sand
The invention relates to an inducer for depositing and solidifying aeolian sand by inducing calcium carbonate through microorganisms and a method for depositing and solidifying aeolian sand, the inducer comprises a bacterial liquid, and the bacterial liquid comprises 2.5-3 g of a bacillus pasteurii liquid culture medium, 4-5 g of peptone, 4-5 g of sodium chloride, 18-20 g of agar powder, 900-1000 mL of distilled water and 90-100 mL of urea with the mass fraction of 20%; the cementing liquid is prepared from 50 to 55g of calcium chloride, 25 to 30g of urea and 900 to 1000mL of distilled water; according to the deposition and solidification method, the situation that due to the fact that bacteria are not evenly distributed in desert aeolian sand, calcium carbonate generated through induction is not evenly distributed is improved through a microorganism induced calcium carbonate deposition (MICP) technology; the aeolian sand is separately filled with the bacterial liquid and the cementing liquid, so that uniform calcium carbonate precipitates can be reasonably generated, and the solidification of the aeolian sand is more facilitated.
一种微生物诱导碳酸钙沉积固化风积沙的诱导剂及沉积固化风积沙的方法，其诱导剂包括菌液，含：巴氏芽孢杆菌液体培养基2.5‑3g，蛋白胨4‑5g，氯化钠4‑5g，琼脂粉18‑20g，蒸馏水900‑1000mL，质量分数为20％的尿素90‑100mL；还包括胶结液，含：氯化钙50‑55g，尿素25‑30g，蒸馏水900‑1000mL；沉积固化方法通过微生物诱导碳酸钙沉积技术(MICP)，来提高细菌在沙漠风积沙中分布不均导致诱导生成的碳酸钙分布不均的情况；菌液和胶结液分开灌注风积沙可以合理生成均匀的碳酸钙沉淀，更有利于风积沙的固结。
