摘要

通过对贵州省中部关闭煤矿区煤矸石堆场地表径流及其沉积物进行样品收集与分析

探讨了降雨—径流下煤矸石中污染物的迁移规律及其对周边地表水体质量的影响。结果表明

煤矸石堆场地表径流水的pH值变化达2.64～6.38

污染物以SO

Fe和Mn为主

其浓度变化受煤矸石类型及降雨强度的影响。径流沉积物在静置或扰动下浸水3～28d后

上覆水的pH达2.78～3.71;SO

Mn的浓度变化分别为27～160mg/L

0.3～3.9mg/L

0.6～2.8mg/L。降雨—径流下关闭煤矿区煤矸石堆场的地表径流对周边水体质量的影响主要表现在水体酸化及Fe

Mn污染严重。

Abstract

Water and sediment samples from surface runoff in the coal mine areas of Guizhou Province were collected and analyzed to investigate pollutant migration from gangues and its impacts on water quality of rivers. Results showed that the pH value of runoff was 2.64～6.38 and the main pollutants in runoff were SO24-

and Mn. Their concentrations were affected by gangue type and rainfall intensity. After runoff sediment was immersed for 3～28 days

the pH value of upper water reached 2.78~3.71 and the contents of SO42-

and Mn reached 27～160

0.3～3.9

0.6～2.8 mg/L

respectively. The impacts of surface runoff on water quality of rivers were the acidification of water bodies and serious pollution of Fe and Mn.
