Experimental study on coal gangue applied as anti-seepage and anti-fouling materials

摘要

摘要: 论述了煤矸石在垃圾填埋场防渗垫层应用中的潜在价值。采用渗透试验、Cu²⁺的吸附试验和淋滤试验测定了煤矸石的防渗和防污性能。研究结果表明，煤矸石粉碎料渗透系数可达1×10^-7cm/s以下，对重金属Cu²⁺的吸附过程十分迅速，同时另一种常见工业固体废弃物粉煤灰对重金属Cu²⁺的吸附率接近100%，二者淋滤浸出的重金属离子浓度也较低，可考虑在煤矸石粉为主的防渗材料中添加粉煤灰，从而提高煤矸石防渗材料的吸附性能。煤矸石和粉煤灰有优于传统黏土的防渗和防污特性，这不仅为填埋场防渗材料提供了新的可能选择，也为工业固体废料的资源化提供了一种新途径。

Abstract: The potential use of coal gangue for landfill liners is presented. The effects of coal gangue on hydraulic conductivity, Cu²⁺ adsorption and leachability are tested. The hydraulic conductivity of coal gangue can reach 1×10^-7 cm/s and the adsorption process occurs rapidly. Meanwhile the percentage of Cu²⁺ adsorption on fly-ash is nearly 100%. They have better performance than the traditional clay in anti-seepage capability and anti-fouling property. Consequently, it is concluded that the coal gangue and fly ash can be potential anti-seepage materials for landfill liners.
