DPIV技术在絮凝池流场特性研究中的应用

Application of Digital Particle Image Velocimetry Technique (DPIV) to study of characteristics of flow fields in flocculation pools

利用数字粒子图像测速(DPIV)技术对往复隔板絮凝池中的复杂流场进行测量,分析池内水流特性对絮凝效果的影响机制.结果表明,絮凝池廊道头部流场对絮凝效果有很大影响.为改善絮凝池的流场,可增大池内的有效空间.

DPIV is a noninterfering technique for flow field measurement. With the technique, the complex flow fields in a flocculation pool with reciprocating separators are measured. Then an analysis is made of the mechanism of flow characteristics affecting flocculation. The results show that, in such a flocculation pool, the flow field near the head of galleries has great influences on flocculation, and that the increase of the available space of the flocculation pool can improve the flow field in the pool.
