摘要
主要研究水流紊动对泥沙絮凝的影响。认为水处理方面的絮凝动力学理论可用于研究泥沙絮凝问题。根据试验实测资料及国外有关试验结果研究表明,在紊动状态下,泥沙絮凝存在两个阶段,每个阶段中紊动对泥沙絮凝的影响也有所不同。
In this paper the influence of turbulence on sediment coagulation is stud- ied. The author discusses some theories of flocculation dynamics presented in many researches about wastewater treatment, and thinks that these theories fit to re- search of sediment coagulation. Based on the test of fine sand and compared with othors, the result shows that there are two periods in fines flocculation in turbulent flow in which the influence of trubulence on the flocculation is different.
