公用事业公司必须了解多水源混合时所涉及的问题， 尤其是对配水系统水质的影响。本文描述了一个 多目标技术有助于评估混合物，以确定可接受的水质 用于同时控制配电中的铅、铜、铁和一氯胺水平 系统。混合三种水源——地下水、地表水和脱盐水 对水进行了评估。模拟结果表明，不同的管道材料通常会 排放减排的水质要求相互冲突。例如，腐蚀 铜管和铅管随着碱度的增加而增加，而随着碱度的增加 有助于减少管道中铁腐蚀产物的释放。增加的 硫酸盐减少了铅的释放，但增加了铁的释放。这些冲突的水质 对铅、铜和铁释放的要求意味着公用事业必须评估权衡 水质和腐蚀反应之间的关系。包括10个参考文献和表格。

Utilities must understand the issues involved when multiple source waters are blended, particularly the effect on distribution system water quality. This article describes a multiobjective technique that can help evaluate blends to identify acceptable water quality for simultaneous control of lead, copper, iron, and monochloramine levels in distribution systems. Blends of three source waters - groundwater, surface water, and desalinated water - were evaluated. Modeling results indicated that different pipe materials often have conflicting water quality requirements for release abatement. For example, corrosion of copper and lead pipes was increased by increasing alkalinity, whereas increasing alkalinity was beneficial in reducing the release of iron corrosion products from pipes. Increasing sulfates reduced lead release but increased iron release. These conflicting water quality requirements for lead, copper, and iron release mean that utilities must evaluate the tradeoffs between water quality and corrosion response.
