| 摘 要： | 煤矸石和粉煤灰是煤矿区两种常见的固体废弃物，对环境造成极大的污染。pH波动幅度大是废弃物农用治理的主要障碍之一。对两种废弃物连续浸提时的pH和电导率(EC)进行长期动态监测，结果表明，不同层次的煤矸石尽管风化程度不同，但经过长时间浸取后，pH和EC变化趋势相似，且煤矸石、粉煤灰的pH、EC值有很大的相关性。该试验为今后两种废弃物合理利用奠定了基础。

| Abstract: | Coal slags and fly ash are two common wastes in coal mining areas, which have caused serious environmental problems. One of the main barriers is the wide pH change in two wastes as agricultural use. pH and electricity conductivity (EC) of fly slags and fly ash had been monitored after soaking them into water for one month. The results showed pH and EC change of coal wastes not only had similar tendency but also had correlation even if they came from different profile with different weathering. The study settled the foundation for the two kinds of wastes used properly in the future. |
