摘　　要：分别采用高锰酸钾氧化、高锰酸钾联合液氯氧化净化低温（3-4℃）、含CODMn、氨氮、铁、锰地下水,但投产以来出厂水锰浓度一直难以达标,鉴于此进行了在滤池配水槽投加液氯同步去除CODMn、铁、锰及氨氮的调试运行研究。A系列4#滤池的氯接触氧化除锰、直接氧化除铁及CODMn、折点加氯去除氨氮的研究结果表明,投氯量为12 mg/L可使滤池出水CODMn、铁、锰、氨氮浓度同时达标。根据该池调试结果,对水厂原有加氯管线进行改造并进行全厂的生产性调试,运行数日后,出厂水CODMn、铁、锰、氨氮浓度均达到《生活饮用水卫生标准》（GB 5749—2006）要求。Potassium permanganate oxidation and chlorine combined with potassium permanganate oxidation were applied respectively to remove CODMn, iron, manganese and ammonia from low tempera- ture （3 to 4 ℃ ） groundwater, however, the manganese concentration was always difficult to meet the standard requirements. Therefore, simultaneous removal of CODMn, iron, manganese and ammonia was investigated by adding liquid chlorine into the water distribution channel of filter. The contact oxidation for manganese removal, direct oxidation for iron and CODMn removal and break-point chlorination for am- monia removal were studied in the A 4# filter, and the results showed that chlorine dosage of 12 mg/Lcould simultaneously remove CODMn, iron, manganese and ammonia. Therefore, the original chlorine feed pipelines in the water treatment plant were reconstructed according to the obtained results of A 4# fil- ter, and the productive commissioning of the water treatment plant was performed. After the operation for several days, CODMn, iron, manganese and ammonia in the finished water met the requirements of the Standards for Drinking Water Quality （ GB 5749 - 2006 ）.
