Sulfate-corrosion-resistant curing material for vertical anti-seepage barrier of solid waste storage yard and preparation method and application of sulfate-corrosion-resistant curing material
The invention relates to the field of curing materials, and discloses a sulfate-corrosion-resistant curing material for vertical anti-seepage barrier of a solid waste storage yard and a preparation method and application of the sulfate-corrosion-resistant curing material. The curing material comprises a first component, a second component and a third component; the first component comprises cement; the second component comprises calcium chloride; the third component comprises sulfate reducing bacteria and optional methanogens. According to the curing material disclosed by the invention, a wall body is formed by the curing material prepared from cement and calcium chloride and is matched with methanogens and sulfate reducing bacteria, so that the anti-cracking, anti-seepage and anti-sulfate corrosion capabilities of a barrier wall can be improved, and the service life of the barrier wall is prolonged; and the invasion of pollutants such as heavy metal cations in the solid waste storage yard can be effectively repaired and prevented, and organic pollutants can be degraded.
本发明涉及固化材料领域，公开了一种用于固废堆场垂直防渗阻隔的抗硫酸盐腐蚀固化材料及其制备方法和应用。所述固化材料包括第一组分、第二组分和第三组分；所述第一组分包括水泥；所述第二组分包括氯化钙；所述第三组分包括硫酸盐还原菌和任选的产甲烷菌。本发明所述的固化材料，通过水泥和氯化钙制备的固化材料形成墙体与产甲烷菌和硫酸盐还原菌器配合，不仅可以提高阻隔墙抗裂抗渗抗硫酸盐腐蚀能力，延长阻隔墙的寿命，还可以有效修复和防止固废堆场的重金属阳离子等污染物的侵入和降解有机污染物。
