| 摘要: |
| 根据贵州龙里县“十四五”生态文明专项规划，加强矿山生态修复。研究龙里县湾滩河镇白水岩煤矿涌水污染治理。对涌水水量进行监测，分析出涌水水质呈酸性，废水主要含Fe2+、Mn2+。按照有关要求，设计出水标准为一级A标，工艺比选采用添加熟石灰粉，经过系统工艺流程，出水水质稳定达标，得出该处理工艺适用于煤矿涌水治理，有效改善湾滩河流域生态环境。 |

| Abstract: |
| According to the 14th Five-Year Plan for ecological civilization special plan of Longli County, Guizhou province, mine ecological restoration will be strengthened.To study the water pollution control of Baishuiyan coal mine in Wanantan Town, Longli County.The water inflow was monitored, and the gushing water quality was acidic, and the wastewater mainly contained Fe2+ and Mn2+.According to the relevant requirements, the design water standard is grade A standard, and the process selection adds cooked lime powder. After the system process, the water quality steadily reaches the standard. It is concluded that the treatment process is suitable for coal mine water gushing treatment and effectively improves the ecological environment of Wantan River basin. |
