  • Plant urease-containing soil solidification agent and zero-waste production process thereof
    Patent number: 11827914
    Abstract: The present invention belongs to the technical field of rock and soil reinforcement, and specifically relates to a plant urease-containing soil solidification agent and a zero-waste production process thereof. A crudely-purified plant urease solution includes a large amount of irrelevant proteins, which seriously affects the treatment effect of the soil solidification agent, makes it impossible to achieve an expected construction purpose, and also causes serious waste and environmental pollution. In the present invention, a common plant urease extraction method on the market is optimized to significantly reduce a protein concentration in a plant urease solution, greatly improve the infiltration performance of a plant urease-containing soil solidification agent, and broaden an application range of such a soil solidification agent.
