Sludge curing agent and sludge in-situ curing method
The invention discloses a sludge curing agent and a sludge in-situ curing method, and relates to the technical field of sludge curing. The sludge curing agent comprises the following components: aluminosilicate clinker, fly ash, desulfurized gypsum, metakaolin, bentonite, diatomite, quick lime, slag and an auxiliary agent, the curing agent is in contact with positive ions and negative ions in calcium-containing substances in sludge and then subjected to polymerization and thickening reaction to form mutually-cross-linked latticed polymer chains, and the calcium-containing substances in the sludge are uniformly mixed with the latticed polymer chains. The soil particles are wrapped and connected, and particle pores are filled until the whole soil system is gelled and solidified and bonded into a whole, so that good mechanical properties, water stability, freezing resistance, scouring resistance and aging resistance are achieved. The ecological protection part prepared by using the sludge curing agent solves the ecological environment problems of serious water and soil loss of a bank slope of a traditional timber pile revetment, high manufacturing cost of a concrete pile, incapability of in-situ resource utilization of dredged mud at a river bottom and the like, and meanwhile, a water ecological system and a land ecological system are opened up, so that the revetment can conserve a water source and purify water quality.
本申请公开了一种淤泥固化剂及淤泥原位固化方法，涉及淤泥固化技术领域。淤泥固化剂包括以下组分硅铝酸盐熟料、粉煤灰、脱硫石膏、偏高岭土、膨润土、硅藻土、生石灰、矿渣和辅助剂，固化剂与淤泥中含钙物质中的阳离子、阴离子接触以后，发生聚合、稠化反应，形成相互交联的网格状聚合物链，包裹联接泥土颗粒并填充颗粒孔隙，直到整个泥土体系凝胶并固化粘结成整体，具有良好的力学性能、水稳定性、抗冻性、抗冲刷性和耐老化性。使用本发明的淤泥固化剂制备的生态护件，解决了传统木桩护岸岸坡水土流失严重、混凝土桩造价高、河底疏浚泥无法原位资源化利用等生态环境问题，同时打通了水生态系统与陆地生态系统，使护岸能够涵养水源、净化水质。
