比利时布鲁塞尔的大部分饮用水来自默兹河，该河严重受温带气候区季节性降水的影响。这条河受到人类污水、藻类水华、腐殖物质和硬地下水注入的影响。二氧化氯用于处理厂、泵站和输水管道沿线的清水水库，用于细菌消毒和防止三卤甲烷（THM）的产生。详细介绍了这些设施的处理方案原理，并进行了成本效益分析。 包括11个参考文献、图表。

Brussels, Belgium, obtains much of its potable water supply from the River Meuse, which is heavily influenced by seasonal precipitation in the temperate climatic zone. The river is affected by human sewage, algal blooms, humic substances, and the infusion of hard groundwater. Chlorine dioxide is used at treatment plants, pumping stations, and clear water reservoirs along aqueducts for bacterial disinfection and to prevent trihalomethane (THM) production. Principles of the treatment schemes at these various facilities are detailed and a costbenefit analysis is offered. Includes 11 references, figures.
