| 摘 要： | 煤矸石中含有大量的S、Fe、Mn等元素,在长期的自然淋溶中伴随着一系列反应会对水体造成严重污染、对人们的生产生活造成极大的影响.通过改良煤矸石基质并种植多年生黑麦草,水体的污染就会得到有效的改善.淋溶液中的Fe3+、Mn2+、SO42-浓度可达到符合<国家生活饮用水水质标准(GB5749-2006)>标准,pH值也会维持在弱碱性.为煤矸石废弃地的复垦打下一定的实践基础.

| Abstract: | Gangue containing S,Fe and Mn etc.as well as pollutants generating from a series of reactions accompanying the long-term natural leaching,may bring about a great threat to enviorment.By improving gangue matrix and cultivating the perennial ryegrass,the water body pollution had highly be alleviated in the present work.In the leaching solution,concentration of Fe3+,Mn2+ and SO42-met the requirement of the national life tap water,and the pH value also maintained at the weak alkaline level.Therefore,this measur... |
