Enhanced adsorption type rigid vertical barrier material and preparation method thereof
The invention belongs to the technical field of environmental pollution site risk management and control, particularly relates to an enhanced adsorption type rigid vertical barrier material and a preparation method thereof, and provides the following scheme that the enhanced adsorption type rigid vertical barrier material comprises the following raw materials: 60-75% of in-situ soil, 10-16% of sodium modified bentonite, 5-9% of active magnesium oxide, 7-12% of granulated blast furnace slag and 5-15% of macroporous adsorption resin; compared with a traditional vertical barrier, the enhanced adsorption type rigid vertical barrier has the advantages that the compressive strength is improved by 5%-10%, the adsorption performance is improved by 10%-50%, and the permeability coefficient can still be maintained to be smaller than 10 <-9 > m/s under the action of high-concentration compound pollutants. And the device can be applied to a polluted site with high-concentration composite pollutants.
本发明属于环境污染场地风险管控技术领域，尤其是一种增强吸附型刚性竖向阻隔屏障材料及其制备方法，现提出如下方案，其包括以下原材料：原位土60‑75%、钠化改性膨润土10‑16%、活性氧化镁5‑9%、粒化高炉矿渣7‑12%、大孔吸附树脂5‑15%组成；此增强吸附型刚性竖向阻隔屏障相较于传统竖向阻隔屏障，抗压强度提高5%‑10%，吸附性能提升10‑50%，并且能在高浓度复合污染物作用下，渗透系数仍能维持小于10‑9m/s。能应用于高浓度复合污染物的污染场地。
