摘　　要：运用化学工程中反应器理论,试验分析波式潜流人工湿地(W-SFCW)中的停留时间分布。比较分析传统潜流湿地和理想反应器的流态特征,得出结论:在同样的水力负荷条件下,相对传统潜流人工湿地(SFCW),W-SFCW具有将污染物浓度降到同一浓度值所需时间更短、去除效率更高的内在机制。The residence time distribution in W-SFCW system experiments was studied using the reactor theory, from chemical engineering. Based on analyses and comparisons of the flow characters of SFCW and an ideal reactor, it is concluded that the W-SFCW system has shorter treatment time and higher removal efficiency than an SFCW system under the same hydraulic loading.

关 键 词：波式潜流人工湿地 传统潜流人工湿地 停留时间分布 水流特性
