I-nitrogen iyisici esibalulekile. Kungaba khona ngezindlela ezahlukene emanzini nasenhlabathini emvelweni. Namuhla sizokhuluma ngemibono ye-nitrogen ephelele, i-ammonia nitrogen, i-nitrate nitrogen, i-nitrite nitrogen, ne-Kaishi nitrogen. Ingqikithi ye-nitrogen (TN) inkomba evame ukusetshenziswa ukukala inani lesamba sezinto ze-nitrogen emanzini. Ihlanganisa i-ammonia nitrogen, i-nitrate nitrogen, i-nitrite nitrogen, nezinye izinto ze-nitrogen, njengezimpande ze-nitrate ne-nitrate. I-Ammonia (NH3-N) ibhekisela ekuhlanganiseni okuphelele kwe-ammonia (NH3) nama-ammonia oxides (NH4+). I-alkaline nitrogen ebuthakathaka futhi ingasabela ngokusabela kwebhayoloji namakhemikhali emzimbeni wamanzi. I-Nitral nitrogen (NO3 -N) ibhekisela ekuhlanganiseni kwezimpande ze-nitrate (NO3-). Kuyi-nitrogen ene-asidi eqinile, okuwuhlobo oluyinhloko lwe-nitrogen. Kungaba kusukela emsebenzini webhayoloji we-ammonia nitrogen kanye ne-organic nitrogen emzimbeni wamanzi. I-nitric nitrogen (NO2 -N) ibhekisela ekuhlanganiseni kwempande ye-nitrite (NO2 -). I-nitrogen ene-asidi ebuthakathaka, isandulela se-nitrate nitrogen, futhi ingavela ekuphenduleni kwezinto eziphilayo namakhemikhali emzimbeni wamanzi. I-Kjeldahl-N isho isamba sama-ammonia oxides (NH4+) kanye ne-organic nitrogen (NORG). Iwuhlobo lwe-ammonia nitrogen engavela ekuphenduleni kwebhayoloji namakhemikhali emzimbeni wamanzi.
I-nitrogen emizimbeni yamanzi iyingxenye ebalulekile, engathinta izinga lamanzi, izimo zemvelo zomzimba wamanzi, nokukhula nokuthuthukiswa kwebhayoloji yamanzi. Ngakho-ke, ukuqapha nokulawulwa kwenani le-nitrogen, i-ammonia nitrogen, i-nitrate nitrogen, i-nitrite nitrogen, ne-Kaishi nitrogen emzimbeni wamanzi kubaluleke kakhulu. Okuqukethwe kwe-nitrogen isiyonke kuyinkomba ebalulekile yokukala inani eliphelele lezinto ze-nitrogen emzimbeni wamanzi. Ngokuvamile, inani le-nitrogen eliphelele emzimbeni wamanzi kufanele libe phakathi kwebanga elithile. Ukweqisa noma okuphansi kakhulu kuzothinta izinga lamanzi lomzimba wamanzi. Ngaphezu kwalokho, i-ammonia nitrogen, i-nitrate nitrogen, i-nitrite nitrogen, ne-Kaifer nitrogen nazo ziyizinkomba ezibalulekile zokuthola izinto ze-nitrogen emanzini. Okuqukethwe kwabo kufanele futhi kuthinte izinga lamanzi lomzimba wamanzi ngaphakathi kwebanga elithile.
Njengamanje, amazwe amaningi anemithetho eqinile mayelana nengqikithi ye-nitrogen, i-ammonia, i-nitrate nitrogen, i-nitrite nitrogen, ne-Kaifer nitrogen emanzini. Imiphumela emibi. Ngakho-ke, wonke umuntu kufanele anake ukuqapha nokulawulwa kwezinto ze-nitrogen emanzini ukuze kuqinisekiswe ukuthi izinga lamanzi lomzimba wamanzi lihlangabezana nezindinganiso zombuso. Sekukonke, inani le-nitrogen, i-ammonia nitrogen, i-nitrate nitrogen, i-nitrite nitrogen, ne-Kaifel nitrogen ziyizinkomba ezibalulekile zezinto ze-nitrogen emanzini. Okuqukethwe kwabo kuyinkomba ebalulekile yokulinganisa izinga lamanzi, okubaluleke kakhulu ekuqaphelweni nasekulawuleni. Kuphela ngokuqapha nokulawula okunengqondo kwezinto ze-nitrogen emzimbeni wamanzi lapho singaqinisekisa ukuthi izinga lamanzi lomzimba wamanzi liyahlangabezana nezinga futhi livikela impilo yomzimba wamanzi.
Uhlobo lwe-Lianhua selukhiqize amathuluzi okubona izinga lamanzi iminyaka engu-40. Ingahlinzeka ngemikhiqizo yokutholwa nge-ammonia nitrogen, isamba se-nitrogen, i-nitrogen nitrate, ne-nitrate nitrogen nitrogen.
