Sand fixing agent and efficient sand fixing method based on high-temperature desert area
The invention belongs to the technical field of desert control, and particularly relates to a sand fixing agent and an efficient sand fixing method based on a high-temperature desert area, and the sand fixing agent comprises urease liquid and gelling liquid with the volume ratio of 1: (1-1.5); the gelling liquid comprises the following components: the final concentration of urea is 0.5 to 1.5 mol/L, the final concentration of calcium salt is 0.5 to 1.5 mol/L, and the final concentration of sodium lignin sulfonate is 15 to 20 g/L. Compared with the prior art, the method has the advantages that the sodium lignin sulfonate is added into the gelling liquid to serve as a protective agent for the activity of urease, so that the activity of the urease can be maintained under the high-temperature condition, calcium carbonate can be economically and efficiently generated under the high-temperature condition, the sand stabilization effect of the high-temperature desert area is improved, and huge social, ecological and economic benefits are achieved.
本发明属于沙漠治理技术领域，具体涉及一种固沙剂及基于高温沙漠地区高效固沙方法，包括体积比为1：(1‑1.5)的脲酶液和胶凝液；所述胶凝液包括以下的组分，尿素的终浓度为0.5‑1.5mol/L、钙盐的终浓度为0.5‑1.5mol/L、木质素磺酸钠的终浓度为15‑20g/L。与现有技术相比，本发明通过在胶凝液中加入木质素磺酸钠，作为脲酶活性的保护剂，确保在高温条件下能维持脲酶的活性，使其能高温条件下，经济高效地生成碳酸钙，提高高温沙漠地区固沙效果，蕴含着巨大的社会、生态和经济效益。
