| 摘 要： | 本文对重庆中梁山煤矸石在自然酸度和模拟酸雨下静态态及动态淋溶特征进行了研究。结果表明，淋出液成弱碱性，其中的铅、锌、铬、镍、铜和铁等元素的浓度均超过了水综合排放标准和地面水环境质量标准规定的阈值；在模拟酸雨中上述离子的溶出能力强于在于蒸溜水中；温度升高时各元素及总离子的淋出量增大。

| Abstract: | The leaching characteristics of coal gangue in acid rain and water under the condition of static and dynamic state have been studied.The results are shown the leachate is weak alkali,and the concentration of Pb,Zn,Cr,Ni,Cu and Fe in it exceeded all the low value of environmental standards.The leaching ability of coal gaugue in acid rain is better than that in Water.When temperatur increases the concentration of total ions of various elements in leachate increases. |
