本powerpoint演示文稿首先简要概述了休斯顿的地表水处理 过程和治疗目标。成品水遇到的问题 本文介绍了强化凝固后的锰含量，以及 调查可能的原因， 原水特性，以及 锰通过处理过程。陈述结论如下:成品水中锰问题的调查 揭示了多种因素的组合； 强化混凝处理技术；单深度植物取水口处的沉积物和湖泊可变性； 回流管理；溶液的pH值在源头和内部都得到了控制 污水处理厂； 源头控制是通过层流循环实现的- 增加沉积物中溶解氧水平，防止湖泊翻腾 增加pH值； 处理厂的控制是通过利用苛性碱来提高 过滤前和回流中的pH值；和 根据需要添加高锰酸钾氧化剂以供使用。包括数字。

This powerpoint presentation begins by providing a brief overview of Houston's surface water treatment processes and treatment goals. Problems encountered with finished water manganese levels after enhanced coagulation are presented, along with an investigation into possible causes, raw water characteristics, and manganese through treatment process. Presentation conclusions indicate the following: investigation into Mn problems in finished water revealed a combination of contributing factors; treatment technique for enhanced coagulation; sediments at single depth plant intake and lake variability; management of return flows; solution was pH control both at source and in treatment plant; source control is being accomplished by laminar circulation - increases DO levels at sediments, prevents lake turn overs and increases pH; treatment plant control is by utilization of caustic to raise pH prior to filtration and in return flows; and, potassium permanganate oxidation added for use as needed. Includes figures.
