Nitrogen, Nitrate Nitrogen, Nitrite Nitrogen kunye Kjeldahl Nitrogen

I-nitrogen yinto ebalulekileyo enokubakho ngeendlela ezahlukeneyo emanzini nakwindalo yomhlaba. Namhlanje siza kuthetha malunga neengcamango ze-nitrogen epheleleyo, i-ammonia nitrogen, i-nitrate nitrogen, i-nitrite nitrogen kunye ne-Kjeldahl nitrogen. Iyonke initrogen (TN) luphawu oluqhele ukusetyenziswa ukulinganisa isixa sisonke sazo zonke izinto zenitrogen emanzini. Iquka i-ammonia nitrogen, initrogen yenitrate, i-nitrite nitrogen kunye nezinye izinto zenitrogen ezifana ne-nitrate kunye ne-nitrate. I-Ammonia nitrogen (NH3-N) ibhekisela kugxininiso oludibeneyo lwe-ammonia (NH3) kunye ne-ammonia oxides (NH4+). I-alkaline nitrogen engenamandla kwaye inokufunyanwa kwi-biological and chemical reactions emanzini. I-nitrogen ye-Nitrate (NO3-N) ibhekisela kuxinzelelo lwe-nitrate (NO3 -). Yinitrogen eneasidi kakhulu kunye neyona ndlela iphambili yenitrogen. Inokuthi ithathwe kwi-biological activity of water from ammonia nitrogen and organic nitrogen emanzini. I-nitrogen ye-nitrite (NO2-N) ibhekisela kuxinzelelo lwe-nitrite (NO2 -). I-nitrogen ene-acidic ebuthathaka kunye ne-precursor ye-nitrate ye-nitrojeni, enokuthi ifumaneke ngokuphendula kwebhayoloji kunye neekhemikhali emanzini. I-Kjeldahl nitrogen (Kjeldahl-N) ibhekisa kwisixa se-ammonia oxides (NH4+) kunye nenitrogen ephilayo (Norg). Yi-nitrogen ye-ammonia enokuthi ifumaneke ngokusabela kwebhayoloji kunye neekhemikhali emanzini. I-nitrojeni emanzini yinxalenye ebalulekileyo enokuchaphazela umgangatho wamanzi, iimeko ze-ikholoji, kunye nokukhula nokuphuhliswa kwezinto eziphilayo zasemanzini. Ngoko ke, kubaluleke kakhulu ukubeka iliso kunye nokulawula initrogen epheleleyo, i-ammonia nitrogen, i-nitrate nitrogen, i-nitrite nitrogen, kunye ne-Kjeldahl nitrogen emanzini. Umxholo wenitrogen iyonke luphawu olubalulekileyo lokulinganisa isixa esipheleleyo sezinto zenitrogen emanzini. Ngokubanzi, isiqulatho senitrogen sisonke emanzini kufuneka sibe phakathi koluhlu oluthile. Isiqulatho esiphakamileyo okanye esiphantsi kakhulu siya kuchaphazela umgangatho wamanzi wamanzi. Ukongeza, i-ammonia nitrogen, i-nitrojeni yenitrate, i-nitrite nitrogen, kunye ne-Kjeldahl nitrogen nazo zizalathisi ezibalulekileyo zokubona izinto zenitrogen emanzini. Umxholo wabo kufuneka ube phakathi koluhlu oluthile. Isiqulatho esiphakamileyo okanye esiphantsi kakhulu siya kuchaphazela umgangatho wamanzi wamanzi. Njengesakhamzimba, i-nitrogen ifakwa kumachibi, kwaye eyona mpembelelo ingqalileyo yi-eutrophication:
1) Xa amachibi ekwimeko yendalo, i-oligotrophic okanye i-mesotrophic. Emva kokufumana igalelo lezondlo zangaphandle, inqanaba lezondlo zomzimba wamanzi liyanda, elinokukhuthaza ukuphuhliswa kweengcambu kunye neziqu zezityalo zasemanzini ngaphakathi koluhlu oluthile, kwaye ukutyetyiswa kwezondlo akubonakali.
2) Ngegalelo eliqhubekayo lezondlo ezifana ne-nitrogen, izinga lokusetyenziswa kwezondlo ngohlaza lwasemanzini liphantsi kunomlinganiselo wokunyuka kwe-nitrogen. Ukwanda kwezondlo kubangela ukuba i-algae iphindaphindeke ngamanani amakhulu, ngokuthe ngcembe inciphisa ukungafihli komzimba wamanzi, kwaye uphuhliso lwezityalo zasemanzini luthintelwe de luphele. Ngeli xesha, ichibi liyatshintsha ukusuka kwichibi lohlobo lwengca ukuya kwichibi lohlobo lwe-algae, kwaye ichibi libonisa iimpawu ze-eutrophication.
Okwangoku, amazwe amaninzi anemimiselo engqongqo kumxholo wenitrogen yezinto ezifana nenitrogen epheleleyo, initrogen nitrogen, initrogen yenitrate, initrogen yenitrite kunye neKjeldahl nitrogen emanzini. Ukuba imimiselo iyaphulwa, iya kuba nefuthe elibi kumgangatho wamanzi kunye nemekobume yendalo kumzimba wamanzi. Ngoko ke, wonke umntu kufuneka anikele ingqalelo ekubekweni kweliso kunye nokulawulwa kwezinto ze-nitrogen kwimizila yamanzi ukuqinisekisa ukuba umgangatho wamanzi wamanzi uhlangabezana nemigangatho yelizwe.
Isishwankathelo,iyonke initrogen, i-ammonia nitrogen, initrogen yenitrate, initrogen yenitrite kunye neKjeldahl nitrogenzizalathisi ezibalulekileyo zezinto zenitrogen kwimizimba yamanzi. Umxholo wabo luphawu olubalulekileyo lomgangatho wamanzi, kwaye ukubeka iliso kunye nokulawula kubaluleke kakhulu. Kuphela ngokubeka iliso okufanelekileyo kunye nokulawulwa kwezinto ze-nitrogen kwimizila yamanzi sinokuthi siqinisekise ukuba umgangatho wamanzi uhlangabezana nemigangatho kunye nokukhusela impilo yomzimba wamanzi.
