摘要
本文对"室外给水设计规范"(GBJ13-86)中滤池滤料组成的规定进行了分析和讨论.在肯定了规范对最大粒径和最小粒径的规定具有可靠科学性、实用性的同时,对不均匀系数K80的规定谈了不同的看法,并提出了修改意见.
This paper analyses and discusses the regulation concerning the composition of filter materials in a filter pond about 'The Supply-water Design Regulation outdoors'. It is positively shown that the regulation about the maximum and minimum dimension is reliable, scientific and practical, and at the same time, it takes a different view of non-homogeneous coefficient K80. An idea for modification in given.
