Kev saib xyuas thiab tswj cov khoom siv nitrogen: Qhov tseem ceeb ntawm tag nrho cov nitrogen, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, thiab Kaifel nitrogen

Nitrogen yog ib qho tseem ceeb. Nws tuaj yeem muaj nyob hauv ntau hom hauv lub cev dej thiab av hauv qhov xwm txheej. Niaj hnub no peb yuav tham txog cov ntsiab lus ntawm tag nrho cov nitrogen, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, thiab Kaishi nitrogen. Tag Nrho nitrogen (TN) yog qhov taw qhia uas feem ntau yog siv los ntsuas tag nrho cov khoom nitrogen hauv dej. Nws suav nrog ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, thiab lwm yam nitrogen tshuaj, xws li nitrate cov hauv paus hniav thiab nitrate. Ammonia (NH3-N) yog hais txog cov ntsiab lus ntawm ammonia (NH3) thiab ammonia oxides (NH4+). Nws tsis muaj zog alkaline nitrogen thiab tuaj yeem cuam tshuam los ntawm cov tshuaj lom neeg thiab tshuaj lom neeg hauv lub cev dej. Nitral nitrogen (NO3 -N) yog hais txog qhov concentration ntawm nitrate hauv paus (NO3-). Nws yog ib qho muaj zog acid nitrogen, uas yog daim ntawv tseem ceeb ntawm nitrogen. Nws tuaj yeem yog los ntawm kev ua haujlwm lom neeg ntawm ammonia nitrogen thiab organic nitrogen hauv lub cev dej. Nitric nitrogen (NO2 -N) yog hais txog qhov concentration ntawm nitrite cag (NO2 -). Nws yog tsis muaj zog acidic nitrogen, ua ntej ntawm nitrate nitrogen, thiab tuaj yeem los ntawm cov tshuaj lom neeg thiab tshuaj lom neeg hauv lub cev dej. Kjeldahl-N yog hais txog cov lej ntawm ammonia oxides (NH4 +) thiab organic nitrogen (NORG). Nws yog ib hom ammonia nitrogen tuaj yeem los ntawm cov tshuaj lom neeg thiab tshuaj lom neeg hauv lub cev dej.
Nitrogen nyob rau hauv lub cev dej yog ib qho tseem ceeb, uas yuav cuam tshuam rau cov dej zoo, ecological tej yam kev mob ntawm lub cev dej, thiab kev loj hlob thiab kev loj hlob ntawm dej biology. Yog li ntawd, kev saib xyuas thiab tswj tag nrho cov nitrogen, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, thiab Kaishi nitrogen hauv lub cev dej yog qhov tseem ceeb heev. Cov ntsiab lus ntawm tag nrho cov nitrogen yog ib qho tseem ceeb qhia rau kev ntsuas tag nrho cov nyiaj nitrogen nyob rau hauv lub cev dej. Feem ntau, tag nrho cov ntsiab lus nitrogen hauv lub cev dej yuav tsum nyob rau hauv ib qho kev sib txawv. Ntau dhau los yog qis dhau yuav cuam tshuam rau cov dej zoo ntawm lub cev dej. Tsis tas li ntawd, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, thiab Kaifer nitrogen kuj yog cov cim tseem ceeb los kuaj xyuas cov tshuaj nitrogen hauv dej. Lawv cov ntsiab lus tseem yuav cuam tshuam rau cov dej zoo ntawm lub cev dej hauv ib qho chaw.
Tam sim no, ntau lub teb chaws muaj kev cai nruj rau cov ntsiab lus ntawm tag nrho cov nitrogen, ammonia, nitrate nitrogen, nitrite nitrogen, thiab Kaifer nitrogen hauv dej. Cov teebmeem hnyav. Yog li ntawd, txhua tus neeg yuav tsum tau ua tib zoo saib xyuas thiab tswj cov khoom siv nitrogen hauv cov dej hauv lub cev kom ntseeg tau tias cov dej zoo ntawm lub cev dej ua tau raws li cov qauv ntawm lub xeev. Tag nrho hauv tag nrho, tag nrho cov nitrogen, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, thiab Kaifel nitrogen yog cov cim tseem ceeb rau cov khoom nitrogen hauv dej. Lawv cov ntsiab lus yog qhov ntsuas tseem ceeb rau kev ntsuas dej zoo, uas tseem ceeb heev rau kev saib xyuas thiab tswj. Tsuas yog los ntawm kev saib xyuas tsim nyog thiab tswj cov khoom siv nitrogen hauv lub cev dej tuaj yeem ua kom ntseeg tau tias cov dej zoo ntawm lub cev dej ua tau raws li tus qauv thiab tiv thaiv kev noj qab haus huv ntawm lub cev dej.
Lub npe Lianhua tau tsim cov cuab yeej ntsuas dej zoo rau 40 xyoo. Nws tuaj yeem muab cov khoom kuaj pom nrog ammonia nitrogen, tag nrho nitrogen, nitrogen nitrate, thiab nitrate nitrogen nitrogen.
