摘　　要：在水处理应用当中的沉淀池数值模拟研究近些年取得了很大的进展。自20世纪70年代,国外的研究人员开始进行许多沉淀池场方面的试验研究与数值模拟工作,在试验测量方面进行了原型池与模型池的测量,包括对速度场与浓度场都进行了许多的测量工作。国内于近几年也开始开展一些数值模拟研究工作,但试验测量方面的工作几乎没有。数值模拟技术尚未能很好地发展到实际工程应用的阶段。对模型的最新进展、所需解决的关键性问题进行了总结。In the field of water treatment theory study, the numerical research on sedimentation tank has made great progress recently. Since 1970s, some foreign researchers have started to conduct many numerical simulation and field measurements work on sedimentation tanks, including the velocity and concentration field measurements. In domestic, some numerical simulation work has been conducted in recent years. However, there is almost no measurement work. The numerical modeling technique has not arrived the stage of practical engineering application. Finally, the latest progress in model and some key problems that need to solve were summarized.
