进行了小型试验，以研究特拉华河水中溶解锰的去除情况。之前的中试结果表明，由于胶体二氧化锰[MnO2（s）]物种的突破或再溶解，臭氧氧化、污泥层澄清和过滤不能有效去除锰。增加碱度并不是控制锰的有效手段。但在臭氧氧化后和混凝开始时施用高锰酸钾，可显著提高可溶性锰的去除率。包括9个参考文献、表格和图表。

Bench-scale tests were conducted to investigate the removal of dissolved manganese from Delaware River water. Prior pilot-plant results had indicated that manganese was not effectively removed by ozonation, sludge blanket clarification, and filtration, because of the breakthrough or resolubilization of colloidal manganese dioxide [MnO2(s)] species. Increasing the alkalinity was not an effective means of controlling manganese. But application of potassium permanganate after ozonation and at the beginning of coagulation considerably improved the removal of soluble manganese. Includes 9 references, tables, figure.
