往复隔板絮凝池不同边壁形状水流结构对混凝沉淀效果有影响,但由于往复隔板絮凝池廊道狭窄、絮凝池拐弯水流结构复杂,致使整个流场的量测十分困难。应用粒子图像测速技术,建立了研究往复隔板絮凝池水流结构的室内测试系统。对往复隔板絮凝池拐弯处水流涡漩运动进行了研究,使用量测系统软件,对不同方案下水流涡漩运动进行了分析,并对混凝沉淀效果进行了比较。 However, due to the narrow corridor of the flocculation pool of the reciprocating partition and the complicated structure of the flocculation flow in the flocculation basin, it is very difficult to measure the whole flow field. Using particle image velocimetry, an indoor test system for studying the flow structure of the reciprocating bulkhead flocculation tank was established. The swirling motion of the water flow at the turn of the flocculating tank of the reciprocating bulkhead was studied. Using the measuring system software, the swirling motion of the water flow under different schemes was analyzed, and the effect of coagulation and sedimentation was compared.
