煤矿废水处理工艺及应用分析

Analysis and Application of Coal Mine Wastewater Treatment Process

通过分析煤炭废水的来源及其分类,介绍了高悬浮废水的混凝工艺、高矿化度废水的脱盐法和酸性废水中和法等不同水质的煤矿废水常见处理工艺,研究了各种处理方法的适用范围及优缺点,以两个典型的矿井水处理应用为实例,阐明在处理实际煤矿废水中核心处理单元的选取是处理废水的关键,同时指出选取工艺时要注意将理论与实际结合,提出符合当地实际水平的处理工艺流程。

Through analysis on coal mine wastewater source and classification, the common coal mine waste water treatment process was summarized, including coagulation of high suspension water, desalination of high salinity waste water, and neutralization of acid waste water. The application ranges, advantages and disadvantages of the processes were discussed. Based on the coal mine wastewater treatment practices, the paper pointed out that, the selection of core treatment unit was the key in waste water treatment, and the combination of theory and practice was necessary for the process design suitable for local conditions.
