- 摘要:
- 某煤矿矿井水含有大量悬浮颗粒等污染物，通过超磁分离技术在井下直接处理，对处理流程、主要构筑物设计参数、运行效果和技术经济分析等进行了介绍。运行结果表明，矿井水处理后水质优于《煤炭工业污染物排放标准》（GB 20426—2006），实现出水就近回用，运行成本约0.21 元/m3，运行费用约115 万元/a，产生的经济效益为777 万元/a，实现了清水入仓、清水上井，对该煤矿企业节能降耗、减污降排产生了良好推动作用。
- Abstract:
- Coal mine water usually contains a large amount of pollutants such as suspended particulates. Ultra-magnetic-separation technology was adopted to treat the coal mine water directly downhole. The treatment process, design parameters of main structures, operational effects and technical & economic analysis were introduced. The operation result showed that effluent quality of the system was better than Emission Standard for Pollutants from Coal Industry (GB 20426-2006), and the effluent could be recycled locally. The operation cost was about 0.21 yuan/m3. The annual operation cost was about 1.15 million yuan, and annual economic benefit was about 7.77 million yuan. It had realized the clean water into storage and clean water out of well, and played a positive role in promoting the energy conservation, consumption reduction and emission reduction of coal mining enterprises.
