粗濾池 的英文怎麼說
中文拼音 [cūlǜchí]
粗濾池
英文
coarse filter-
Through choosing different diameter of sand granule, using fecl3 and pac as the coagulants, doing paralleled test through standard filtration column compared with referenced filtration columns ( the coarser and the finer sand granule used as filtration media separately ), the thesis investigates the correlation between the filtration behavior and the depth of the deep bed l, the diameter of the sand granule d
本文採用不同粒徑的石英砂濾料，以fecl _ 3 、 pac作為混凝劑，通過進行標準濾池與參照濾池（分別裝填細濾料、粗濾料）的平行對比試驗，研究濾料粒徑改變后，濾池過濾特性與濾池深度l 、濾料粒徑d的相關關系。This study tries to use upflow rough filtration as the pretreatment for slow sand filtration
摘要嘗試採用上向流粗濾，作為慢濾池的預處理。A computer - aided simulation used to observe the influence of changing filtration parameter on upflow rough filtration is necessary because of the long term of operation cycle
由於粗濾池的運行周期很長，故採用了計算機模擬的方式觀察運行參數變化對粗濾池的影響。
