Ammonia nitrogen, raws li tus qauv ntsuas dej tseem ceeb, ib txwm muaj txiaj ntsig zoo hauv kev kho cov dej khib nyiab nrog ammonia nitrogen.
Qhov tseeb, ammonia nitrogen tshem tawm cov neeg ua haujlwm feem ntau siv cov neeg ua haujlwm hauv cov dej khib nyiab ammonia nitrogen tshem tawm, uas tuaj yeem daws qhov teeb meem ntawm ammonia nitrogen tshaj tus qauv. Txoj kev siv yog yooj yim, cov tshuaj tiv thaiv yog ceev, thiab nws yog ceev thiab zoo.
Ammonia nitrogen tshem tawm cov neeg ua haujlwm feem ntau decompose ammonia nitrogen hauv dej los ntawm kev muaj zog oxidation. Tom qab ntxiv cov tshuaj, tsis muaj sediment yuav tsim, thiab cov khoom decomposition yuav tsis recombine. Feem ntau yog siv los tshem tawm ammonia nitrogen los ntawm cov dej khib nyiab, ntxiv rau nws los tsim cov nitrogen tsis sib haum, nitrogen dioxide, nitric oxide, thiab dej. Cov tshuaj tiv thaiv catalytic hauv ammonia nitrogen tshem tawm tus neeg sawv cev hloov cov ionic ammonia nitrogen hauv cov dej khib nyiab rau hauv lub xeev dawb, thiab cov txheej txheem tshuaj tiv thaiv tuaj yeem ua tiav nyob rau hauv li ntawm 5-10 feeb, nrog rau kev tshem tawm siab.
Cov yam ntxwv ntawm ammonia nitrogen tshem tawm cov neeg ua haujlwm:
1. Cov tshuaj tiv thaiv ceev ceev, thiab cov txheej txheem tshuaj tiv thaiv tuaj yeem ua tiav hauv li 5-10 feeb.
2. Kev tshem tawm kev ua haujlwm siab yog siab, thiab piv rau lwm cov tshuaj ammonia nitrogen tshem tawm, nws muaj qhov sib ntxiv me me thiab muaj txiaj ntsig zoo.
3. Yooj yim rau ntxiv thiab siv, ua haujlwm zoo
Kev siv cov tshuaj ammonia nitrogen tshem tawm:
Thaum siv nyob rau hauv ib qho kev sim me me, yaj cov tshuaj ammonia nitrogen tshem tawm mus rau hauv 5% aqueous tov ua ntej ntxiv nws. Raws li tus nqi ammonia nitrogen ntawm cov dej khib nyiab, ntxiv 100ppm ntawm ammonia nitrogen tus neeg sawv cev tuaj yeem tshem tawm kwv yees li 6-8ppm ntawm ammonia nitrogen (tus nqi siv). Cov tshuaj tiv thaiv yuav siv li ntawm 5-10 feeb kom ua tau zoo, tsis muaj qhov seem lossis nag lossis daus.
