Kuyang'anira ndi kuyang'anira zinthu za nayitrogeni: Kufunika kwa nayitrogeni, ammonia nitrogen, nayitrogeni wa nitrate, nayitrogeni wa nitrite, ndi Kaifel nitrogen.

Nayitrogeni ndi chinthu chofunikira. Zitha kukhalapo m'njira zosiyanasiyana m'madzi ndi m'nthaka m'chilengedwe. Lero tikambirana mfundo za nayitrogeni, ammonia nayitrogeni, nayitrogeni wa nitrate, nayitrogeni wa nitrite, ndi nayitrogeni wa Kaishi. Total nitrogen (TN) ndi chizindikiro chomwe chimagwiritsidwa ntchito poyeza kuchuluka kwa nayitrogeni m'madzi. Zimaphatikizapo ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, ndi zinthu zina za nayitrogeni, monga mizu ya nitrate ndi nitrate. Ammonia (NH3-N) amatanthauza kuchuluka kwa ammonia (NH3) ndi ammonia oxides (NH4+). Ndiwofooka wamchere wa nayitrogeni ndipo ukhoza kuchitidwa kudzera muzochita zamoyo ndi mankhwala m'madzi. Nitral nitrogen (NO3 -N) amatanthauza kuchuluka kwa mizu ya nitrate (NO3-). Ndi asidi wa nayitrogeni wamphamvu, womwe ndi mtundu waukulu wa nayitrogeni. Kungakhale kwachilengedwenso ntchito ammonia asafe ndi organic asafe mu madzi thupi. Nitric nayitrogeni (NO2 -N) amatanthauza kuchuluka kwa mizu ya nitrite (NO2 -). Ndiwofooka acidic nayitrogeni, kalambulabwalo wa nayitrogeni wa nayitrogeni, ndipo imatha kubwera kuchokera kuchilengedwe komanso momwe zimachitikira m'madzi. Kjeldahl-N amatanthauza kuchuluka kwa ammonia oxides (NH4+) ndi organic nitrogen (NORG). Ndi mtundu wa nayitrogeni wa ammonia womwe ukhoza kubwera kuchokera kuchilengedwe komanso momwe zimachitikira m'madzi.
Nayitrojeni m'madzi ndi gawo lofunikira, lomwe lingakhudze mtundu wamadzi, momwe chilengedwe chimakhalira m'madzi, komanso kukula ndikukula kwa biology yamadzi. Choncho, kuyang'anira ndi kulamulira kwa nayitrogeni yonse, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, ndi Kaishi nitrogen m'madzi ndikofunika kwambiri. Zomwe zili mu nayitrogeni ndi chizindikiro chofunikira choyezera kuchuluka kwa nayitrogeni m'madzi. Nthawi zambiri, nayitrogeni yonse yomwe ili m'madzi iyenera kukhala yosiyana. Kuchuluka kapena kutsika kwambiri kudzakhudza ubwino wa madzi a thupi lamadzi. Kuphatikiza apo, ammonia nayitrogeni, nayitrogeni wa nitrate, nayitrogeni wa nitrite, ndi nayitrogeni wa Kaifer nawonso ndizizindikiro zofunika kuzindikira zinthu za nayitrogeni m'madzi. Zomwe zili nazo ziyeneranso kukhudza ubwino wa madzi a madzi amtundu wina.
Pakalipano, mayiko ambiri ali ndi malamulo okhwima okhudza kuchuluka kwa nayitrogeni, ammonia, nayitrogeni wa nitrate, nayitrogeni wa nitrite, ndi nayitrogeni wa Kaifer m'madzi. Zotsatira zoyipa. Choncho, aliyense ayenera kuyang'anitsitsa kuyang'anira ndi kuyang'anira zinthu za nayitrogeni m'madzi kuti atsimikizire kuti madzi a m'madzi akugwirizana ndi miyezo ya boma. Zonsezi, nayitrogeni yonse, ammonia nitrogen, nayitrogeni wa nitrate, nayitrogeni wa nitrite, ndi nayitrogeni wa Kaifel ndizizindikiro zofunika za nayitrogeni m'madzi. Zomwe zili m'gululi ndi chizindikiro chofunikira poyezera kuchuluka kwa madzi, zomwe ndizofunikira kwambiri pakuwunika ndi kuwongolera. Pokhapokha poyang'anitsitsa ndi kuyang'anira zinthu za nayitrogeni m'madzi m'madzi tingathe kuonetsetsa kuti madzi a m'madzi akugwirizana ndi muyezo ndikuteteza thanzi la madzi.
Mtundu wa Lianhua wapanga zida zowunikira madzi kwa zaka 40. Itha kupereka zinthu zodziwikiratu ndi ammonia nitrogen, nayitrogeni yonse, nayitrogeni nitrate, ndi nayitrogeni wa nayitrogeni wa nitrate.
