刘锡年:(中国城市规划设计研究院) 一、据目前国内对混凝设备研究情况,1983年中南给水排水设计院对高效能混合絮凝进行了比较系统的试验研究,对混凝动力学作了较深入的探讨,推荐出高效节能的竖流式多层网格混凝设备,并经过了生产实际的检验。另外对坎布准数GT值提出一些分析意见和新的补充看法。在混凝的理论和实践方面前进了一步,有些新意。 他们在研究混凝动力学中引用了各向同性湍流理论。在各向同性湍流中小涡旋处于惯性区向粘性区过渡的临界状态,能够促进凝聚现象的正是这个临界状态的涡旋λ_0。所以在混凝
Liu Xinian: (China Academy of Urban Planning and Design) I. According to the current situation of domestic research on coagulation equipment, in 1983, the Central South Water Supply and Drainage Design Institute conducted comparative systematic experiments on high-performance mixed flocculation and compared the kinetics of coagulation. In-depth discussion, recommending a highly efficient energy-saving vertical multi-layer grid coagulation equipment, and after production of the actual inspection. In addition, some analysis opinions and new supplementary opinions on the CAM value of Cambium are presented. A step forward in the theory and practice of coagulation, some new ideas. They cited the theory of isotropic turbulence in the study of the kinetics of coagulation. In the isotropic turbulent flow, the small vortex is in the critical state of transition from the inertial zone to the viscous zone. The vortex λ_0, which is the critical state, can promote the condensation phenomenon. So in coagulation
