Ukubeka iliso kunye nokulawulwa kwezinto zenitrogen: Ukubaluleka kwenitrogen epheleleyo, i-ammonia nitrogen, initrogen yenitrate, initrogen yenitrite, kunye neKaifel nitrogen.

I-nitrogen yinto ebalulekileyo. Inokubakho ngeendlela ezahlukeneyo kumzimba wamanzi kunye nomhlaba kwindalo. Namhlanje siza kuthetha malunga neengcamango ze-nitrogen epheleleyo, i-ammonia nitrogen, i-nitrate nitrogen, i-nitrite nitrogen, kunye ne-Kaishi nitrogen. Iyonke initrogen (TN) luphawu oludla ngokusetyenziswa ukulinganisa isixa sisonke sezinto zenitrogen kwimizila yamanzi. Iquka i-ammonia nitrogen, i-nitrate nitrogen, i-nitrite nitrogen, kunye nezinye izinto ze-nitrogen, ezifana neengcambu ze-nitrate kunye ne-nitrate. I-Ammonia (NH3-N) ibhekisela kugxininiso olubanzi lwe-ammonia (NH3) kunye ne-ammonia oxides (NH4+). I-alkaline nitrogen engenamandla kwaye inokuphendulwa ngokuphendula kwebhayoloji kunye neekhemikhali kumzimba wamanzi. I-nitrogen ye-nitral (NO3 -N) ibhekisela kugxininiso lwengcambu ye-nitrate (NO3-). Yinitrogen enamandla eneasidi, eyona ndlela iphambili yenitrogen. Inokuthi ivela kumsebenzi webhayoloji we-ammonia nitrogen kunye ne-nitrogen ephilayo kumzimba wamanzi. I-nitric nitrogen (NO2 -N) ibhekisela kugxininiso lwengcambu ye-nitrite (NO2 -). I-nitrogen ene-acidic ebuthathaka, isandulela se-nitrate nitrogen, kwaye inokuvela kwi-biological and chemical reactions kumzimba wamanzi. I-Kjeldahl-N ibhekisa kwisixa se-ammonia oxides (NH4+) kunye nenitrogen ephilayo (NORG). Luhlobo lwenitrogen ye-ammonia enokuthi ivele kwi-biological and chemical reactions kumzimba wamanzi.
I-nitrogen ekwimizila yamanzi yinxalenye ebalulekileyo, enokuthi ichaphazele umgangatho wamanzi, iimeko ze-ecological kumzimba wamanzi, kunye nokukhula nophuhliso lwebhayoloji yamanzi. Ngoko ke, ukubeka iliso kunye nokulawulwa kwe-nitrogen epheleleyo, i-ammonia nitrogen, i-nitrate nitrogen, i-nitrite nitrogen, kunye ne-Kaishi nitrogen kumzimba wamanzi kubaluleke kakhulu. Umxholo wenitrogen epheleleyo sisalathisi esibalulekileyo sokulinganisa isixa esipheleleyo sezinto zenitrogen kumzimba wamanzi. Ngokuqhelekileyo, umxholo we-nitrogen opheleleyo kumzimba wamanzi kufuneka ube phakathi koluhlu oluthile. Ukugqithisa okanye okuphantsi kakhulu kuya kuchaphazela umgangatho wamanzi womzimba wamanzi. Ukongeza, i-ammonia nitrogen, i-nitrojeni ye-nitrate, i-nitrite nitrogen, kunye ne-Kaifer nitrogen nazo zizibonakaliso ezibalulekileyo zokubona izinto ze-nitrogen emanzini. Umxholo wabo kufuneka uchaphazele umgangatho wamanzi womzimba wamanzi ngaphakathi koluhlu oluthile.
Okwangoku, amazwe amaninzi anemimiselo engqongqo kumxholo wenitrogen, ammonia, nitrate nitrogen, nitrite nitrogen, kunye neKaifer nitrogen emanzini. Imiphumo emibi. Ngoko ke, wonke umntu kufuneka anikele ingqalelo esweni kunye nokulawulwa kwezinto ze-nitrogen kumzimba wamanzi ukuqinisekisa ukuba umgangatho wamanzi womzimba wamanzi udibana nemigangatho karhulumente. Lilonke, iyonke initrogen, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, kunye neKaifel nitrogen zizalathisi ezibalulekileyo zezinto zenitrogen emanzini. Umxholo wabo uyisilathisi esibalulekileyo sokulinganisa umgangatho wamanzi, obaluleke kakhulu ukubeka iliso nokulawula. Kuphela ngokubeka iliso okufanelekileyo kunye nokulawulwa kwezinto ze-nitrogen kumzimba wamanzi sinokuqinisekisa ukuba umgangatho wamanzi womzimba wamanzi udibana nomgangatho kwaye ukhusela impilo yomzimba wamanzi.
Uphawu lwe-Lianhua luvelise izixhobo zokubona umgangatho wamanzi iminyaka engama-40. Inokubonelela ngeemveliso zokubona nge-ammonia nitrogen, initrogen epheleleyo, initrogen nitrate, kunye nenitrogen nitrogen nitrogen.
