快滤池复合滤料间极限粒径的配比是否适当,对滤池的效能有重大的影响。本文通过对试验资料的分析,指出一般常用的配比计算方法的欠合理性;并结合理论分析,提出煤滤料最小粒径及最大粒径与砂滤料最小粒径间的配比关系新计算方法。
The appropriate ratio of the limiting particle size between the composite filter media in the fast filter tank has a significant impact on the efficiency of the filter. This paper analyzes experimental data and points out the unreasonableness of commonly used ratio calculation methods. Combined with theoretical analysis, it proposes a new relationship between the minimum particle size of coal filter material and the minimum particle size of sand filter material. Calculation method.
