Cov npuas mos tej vs. coarse riffabers txawv: science ntawm cov pa oxygen hloov efficiency
Qhov tseem ceeb ntawm lub cev
Cov pa oxygen hloov kev ua haujlwm (ote)Nyob rau hauv kev kho dej kom haum raws Henry txoj cai thiab Fick txoj cai diffusion hauv paus ntsiab lus. Qhov tseem ceeb txiav txim siab yogCov cheeb tsam npuas rau ib qho ntim:
Cov npuas npuas nplua(0.5-3mm inch) muab 2.8 m² / l thaj chaw
Coarse striffersers(5-20mm) muab tsuas 0.3 M² / L
Qhov no 9: 1 piv txwv hais tias vim li cas cov npuas zoo ua tiav 42-55% ote vs . 15-25% rau cov tshuab ntxhib. Txawm li cas los xij, cov khoom siv science thiab kev ua haujlwm tsis zoo ua kom hloov kho tiag-ntiaj teb kev ua haujlwm.
