倒锤型上向流直接过滤滤池简称KO-1型上向流直接过滤滤池,有如下优点。1.池体呈倒锤型,滤料的粒径是下大上小,因此,当原水一进入池底层时,滤速为最大,当水流上移时,滤速逐渐减少,达最大许可值。池底部速料的粒径比等截面上向流直接过滤滤池底部的滤料粒径大,这样可提高整个滤层的截污能力。而上部滤料的粒径,倒锤型上向流直接过滤滤池比等截面上向流直接过滤滤池小,原水中的细小污物,即使穿过底部粗滤料层,也可被上层细滤料除去,提高
The inverted-hammer upflow direct filtration filter is referred to as the KO-1 upflow direct filtration filter and has the following advantages. 1. The pool body is of inverted hammer type. The particle size of the filter media is large and small. Therefore, when raw water enters the bottom of the pool, the filtration rate is the maximum. When the water flow moves up, the filtration rate gradually decreases to the maximum allowable value. . The particle size of the material at the bottom of the tank is larger than the size of the filter material at the bottom of the direct filtration filter in the same cross-section, which can improve the interception capacity of the entire filter layer. The particle size of the upper filter material, the direct flow filtration filter tank of the inverted hammer type upward flow is smaller than that of the direct flow filtration filter of the equal flow, and the fine dirt in the raw water can be used as the top layer even through the bottom coarse filter material layer. Fine filter material removed and increased
