中文摘要
应用灰关联熵分析方法，以SUFR系统厌氧区释磷效果为目标，研究导流参数对该系统厌氧释磷效果影响的重要性顺序。试验结果表明，各导流参数对厌氧释磷均有着明显的影响，且各参数对厌氧释磷效果影响的强弱顺序依次为：导流转速＞导流叶片的折角＞导流叶片的串联层数＞d/D。该结果对SUFR系统在三峡库区的工程应用具有一定的指导意义。
英文摘要
The method of grey relational entropy was used to analyze the phosphorus release in the anaerobic zone of the SUFR system. The results showed that the rotational speed，the pitch angle of the guiding vane，d/D， and the layers of multistage vane play important roles in the anaerobic zone. The decreasing effect sequence of the four factors is: the rotational speed＞the pitch angle of the guiding vane＞the layers of multistage vane＞d/D. This method was useful to the practical operation of the SUFR system in the Three Gorge Reservoir Region.
