Study on Treatment of Mine Water and Its Cost Analysis

During the process of coal production, mine water pollution is serious. It will become a threat to ecological environment in coal mining area if this kind of water is drained away to the nature directly. Take Jialong coal mine as an example, we analyzed major qualities of mine water, provided specific process of treatment of mine water, and demonstrated the feasibility, effectiveness, cost of mine water disposal technology. The result showed to us that the process adopted is effective in removing the sewage from mine water, such as CODCr, SS, Fe, Mn. The treated water meets the standards of emission or recycling and its cost is low too. So this process has great promotional value.
