The use of baffles in sewer systems enables the capture of floatables, which could be responsible for both malfunctioning of water treatment plants and aesthetic pollution of receiving bodies when discharges through combined sewer overflow devices occur. An experimental contribution to the understanding of capturing processes of floatable elements by means of baffle devices is presented in this paper. Experiments were carried out using different baffle configurations. The limit equilibrium conditions of various types of floatables, i.e the condition beyond which upstream intercepted floatables start to escape the baffle, were investigated. The dimensional analysis was used in order to generalize the results of the experiments and to compare the capturing performances of analysed baffle configurations.
在下水道系统中使用挡板能够捕获漂浮物，当通过合流制下水道溢流装置排放时，这些漂浮物可能会导致污水处理厂故障以及受纳水体的美学污染。本文给出了一项关于借助挡板装置理解漂浮物捕获过程的实验研究。实验采用了不同的挡板配置。研究了各类漂浮物的极限平衡条件，即上游拦截的漂浮物开始逃离挡板的条件。为了归纳实验结果并比较所分析的挡板配置的捕获性能，采用了量纲分析。
