英文摘要: Abstract(#br)Residence time distributions (RTDs), obtained from tracer experiments, are one of the main tools for investigating the hydraulic performance of constructed wetlands. However, the existence of various hydraulic indexes derived from RTDs has led to inconsistency in their application for comparing the hydraulic performance. In this work, eight hydraulic indexes were initially selected based on their popularity, and then divided into three categories: hydraulic efficiency indexes (HEIs) ( λ m , λ e , λ p , and MI ), short-circuiting indexes (SIs) ( t 5 and t 10 ), and mixing indexes (MIs) ( σ 2 and Morril index). Then, the hydraulic indexes were optimized for compatibility, discrimination, difficulty, and their mutual relationships between different categories. The results showed...
