涡旋澄清池反应区数值模拟研究

Study on Flow Numerical Simulation of Vortex Coagulation Clarifier Reaction Zone

众多的工程实践证明,涡流澄清技术具有较好的经济效益及社会效益。为更好利用该技术,利用Fluent软件模拟水流在涡旋澄清池反应区中的涡旋尺度、涡旋分布、流场状态,获得反应器内部流场的详细信息,同时利用Zeta电位仪及FCD(絮凝光学检测仪)检测絮体Zeta电位及其结构形状的变化情况,通过数值模拟及现场试验,验证并分析了涡旋澄清池反应区中的相关流动参数,提出了影响絮凝效果的因素及规律。

The projects have proved that the vortex coagulation technology has good economic and social benefits.In order to make better use of this technology,this paper analyzes the relevant flow parameters of vortex coagulation clarifier reaction zone through the numerical simulation and the experiment,proposing the influence factors and principles on flocculation.
