以矿井排水为水源的电厂项目取水水源论证

Water source demonstration for power plant project using mine drainage

在分析永城矿区区域水文地质状况的基础上,采用富水系数法和"大井法",并结合实测数据,对矿区各矿井涌水量进行分析计算,并评价其水质,论证其作为电厂生产用水水源的可靠性与可行性。分析结果表明:矿区有保证的可供电厂利用的矿井排水量为917 m3/h,但矿井排水由于受煤粉、岩粉等污染,水质不达标,需经过深度处理才能满足电厂循环冷却水及锅炉补充水的用水要求。

Based on Yongcheng mining area hydrogeological conditions,using rich water coefficient method and ＂virtual large diameter well＂method,combing measured data,the mine inflow of each mining had been analyzed and calculated,the water quality also had been evaluated in order to demonstration the reliability and feasibility as the process water of power plant. The results show that 917 m3/ h water quantity could be used for plant,but the water quality indicators are not reaching standard,and need furthermore treatment on water quality in order to meet the requirements of process water.
