肥城大封电厂矿井水除铁工艺选择研究

肥城大封煤矿由于水质突变含铁量高达690mg/L,不能满足大封煤矸电厂的用水标准,且达不到矿井水排水标准属于罕见的含铁极高的矿井水排水。通过曝气氧化实验、pH值调整实验、絮凝沉淀实验、接触氧化实验和除铁效果实验等一系列实验确定组合工艺处理肥城大封矿井排水,使之达到电厂用水水质标准。主要通过实验数据探讨处理含铁量极高矿井水处理的组合工艺,并依据工程的实际探讨工艺的可行性。 The iron content of mine water reach to 690mg/L due to the changing of water quality, this can not meet the water standerds of coal gangue power plant and drainage. Deal with the mine water through the aeration oxidation experiment, pH adjustment experiment, flocculation sedimentation experiment, contact oxidation experiment and effects of removing iron and a series of experiments to bring it up to meet the standards of power plant water. Explore the best combined process according to experimental data and discuss the feasibility based on practicality
