Method for solidifying sludge soil based on urease induced calcium carbonate deposition
The invention discloses a method for solidifying sludge soil based on urease induced calcium carbonate deposition. The method for solidifying the sludge soil comprises the following steps: injecting a urease-based curing agent into sludge, and standing after injection until the standard of engineering application is reached. According to the method for solidifying the sludge soil, urease liquid and gelling liquid are adopted as the curing agent, the urease liquid is soybean urease liquid, the gelling liquid is the mixed liquid of calcium chloride and urea, calcium carbonate is induced to deposit through urease, the advantages of being free of pollution and chemical residues are achieved, environmental protection is achieved, and the curing agent is wide in raw material source, low in cost, convenient to operate, good in curing effect, good in economic benefit, high in practicability and beneficial to popularization and application, and has important practical significance on resource utilization of the sludge.
本发明公开了一种基于脲酶诱导碳酸钙沉积固化淤泥土的方法，所述固化淤泥土的方法是向淤泥中注入基于脲酶的固化剂，注入后静置，达到工程应用的标准即可。采用本发明所述的固化淤泥土的方法，采用脲酶液和胶凝液作为固化剂，其中所述脲酶液为大豆脲酶液，而所述胶凝液为氯化钙和尿素混合液，利用脲酶诱导碳酸钙沉积，具有无污染及无化学残留的优点，不仅绿色环保，而且固化剂的原料来源广泛、成本低廉，操作方便，且固化效果较好，具有良好的经济效益，对淤泥的资源化利用有重要现实意义，其实用性强，有利于推广应用。
