摘要
监测了不同粒径的煤矸石、粉煤灰及其不同配比的基质在水的长时间漫泡下,其pH的变化规律。并寻找出了适宜于作物生长的粉煤灰与煤矸石的最佳pH配比比例为4:1-8:1。为进一步就地取材,以废治废提供新的思路,可以减少煤矿区生态恢复的费用,具有很好的实际应用潜力。
pH had some changes after fly ash and coal wastes soaked into water for a long time.The optimum pH value suitable for the plant growth had been got by mixing fly ash and coal wastes as ratio 4 : 1 - 8 : 1, That can reuse the wastes in the future and reduce the reclamation fee in coal mining areas.
