在国内随着斜板(管)在水处理中的普遍应用,对它的水力计算也引起人们的普遍关注。近年来就田中和美的分离粒径法和姚氏的特性参数法的计算问题存在着争议。分歧主要集中在分析方法、两种计算方法的同异、那一种方法较为切合实际以及斜板与斜管那一种方法沉淀效果好等问题上。以往的讨论主要集中于前两个问题,后两个问题的讨论则较少。然而它们的解决对生产实践 In China, with the universal application of inclined plates (pipes) in water treatment, its hydraulic calculation has also attracted people’s attention. In recent years, there have been controversies regarding the calculation of the separation particle size method of Tanaka and the United States and Yao’s characteristic parameter method. Disagreements mainly focus on the analysis method, the difference between the two calculation methods, the one that is more practical, and the precipitation effect of the inclined plate and inclined tube. The previous discussions focused on the first two issues, while the discussion on the latter two issues was less. However, their solution to production practices
