Leakage teb thaum muaj xwm ceev
Cais thaj chaw uas muaj kab mob los ntawm kev tawm thiab teeb tsa cov cim ceeb toom nyob ib puag ncig nws. Nws raug pom zoo tias cov neeg ua haujlwm xwm txheej ceev yuav tsum hnav lub npog ntsej muag roj thiab cov khaub ncaws tiv thaiv tshuaj. Tsis txhob nkag mus rau hauv cov khoom xau ncaj qha, zam cov plua plav, ua tib zoo cheb nws, npaj cov tshuaj txog li 5% dej lossis kua qaub, maj mam ntxiv cov dej ammonia kom txog thaum nag lossis daus tshwm sim, thiab tom qab ntawd muab pov tseg. Koj tuaj yeem yaug nrog dej ntau, thiab dilute cov dej ntxuav rau hauv cov dej khib nyiab. Yog tias muaj ntau qhov dej ntws tawm, tshem tawm raws li kev taw qhia ntawm cov neeg ua haujlwm. Txoj kev pov tseg pov tseg: Sib tov cov khib nyiab nrog sodium bicarbonate, tshuaj tsuag nrog dej ammonia, thiab ntxiv dej khov. Tom qab cov tshuaj tiv thaiv nres, yaug nrog dej rau hauv lub kav dej.
Kev tiv thaiv
Kev tiv thaiv ua pa: Thaum raug plua plav, yuav tsum hnav lub npog ntsej muag roj. Hnav ib lub tshuab ua pa uas muaj tus kheej thaum tsim nyog.
