为减少三卤甲烷（THM）的形成而优化水处理的尝试导致需要对除锰进行修改。本文综述了次氯酸、高锰酸钾、二氧化氯和过氧化氢对地表水供应中还原锰的氧化能力。评估了原水总有机碳浓度、温度和pH值的变化对氧化效率的影响。结果表明，二氧化氯、高锰酸钾和游离氯对锰的氧化是有效的，尽管它们各有优缺点。 游离氯被发现能有效氧化锰，但仅在碱性pH条件下。此外，其用途将仅限于THM生成潜力较低的水域。其他氧化剂价格昂贵，在含有大量有机物的情况下氧化锰效率低下，或者在低温下效率不高。过氧化氢对除锰无效。包括7个参考文献、表格、图表。

Attempts to optimize water treatment for reducing trihalomethane (THM) formation have resulted in the need for modifications with respect to manganese removal. This article reviews the use of hypochlorous acid, potassium permanganate, chlorine dioxide, and hydrogen peroxide for their ability to oxidize reduced manganese from surface water supplies. The effects of changes in the total organic carbon concentration of the raw water, temperature, and pH on oxidation efficiency are evaluated. Results indicate that chlorine dioxide, potassium permanganate, and free chlorine are effective for manganese oxidation, although each had advantages and disadvantages. Free chlorine was found to oxidize manganese efficiently, but only under alkaline pH conditions. Also, its use would be limited to waters with low THM formation potentials. Other oxidants were costly, oxidized manganese inefficiently in the presence of significant organic matter, or were not highly effective at low temperatures. Hydrogen peroxide was found to be ineffective for manganese removal. Includes 7 references, tables, figures.
