Environment functional type composite vertical barrier wall
The invention relates to the technical field of pollutant prevention and control, in particular to an environment function type composite vertical barrier wall which structurally comprises a reduction wall and an oxidation wall, and barrier materials of the reduction wall and the oxidation wall comprise carbide slag (alkali activator), steel slag (gelling agent), bentonite and pollutant adsorbent. Wherein the reduction wall material pollutant adsorbent is iron powder, and the oxidation wall material pollutant adsorbent is sodium perchlorate and iron-rich attapulgite. Wherein silicon and calcium elements in the steel slag are subjected to pozzolanic reaction with metal ions under the alkali excitation action of the carbide slag to generate a gelling product, pores of the wall body are effectively filled, and the anti-seepage performance and the strength of the wall body are improved; iron powder in the reduction wall can reduce pollutant chlorohydrocarbon, sodium perchlorate and iron-rich attapulgite in the oxidation wall can oxidize benzene series and arsenic, and pollutants are removed. The composite vertical barrier wall can be used for a multi-pollutant composite site with high pollution control requirements.
本发明涉及污染物防控技术领域，具体为一种环境功能型复合竖向阻隔墙，阻隔墙结构包括还原墙和氧化墙两部分，还原墙与氧化墙阻隔材料均包括电石渣(碱激发剂)、钢渣(胶凝剂)、膨润土和污染物吸附剂，其中还原墙材料污染物吸附剂为铁粉，氧化墙材料污染物吸附剂为高氯酸钠和富铁凹凸棒土。其中，钢渣中的硅、钙元素经过电石渣碱激发作用与金属离子发生火山灰反应，生成胶凝产物，有效填充墙体孔隙，提升墙体防渗性能和强度；还原墙中的铁粉可还原污染物氯代烃，氧化墙中的高氯酸钠和富铁凹凸棒土可以氧化苯系物和砷，去除污染物。该复合竖向阻隔墙可针对具备污染管控高需求的多污染物复合场地。
