Nitrogen chinhu chakakosha. Inogona kuvapo nenzira dzakasiyana mumvura yemvura uye ivhu mumasikirwo. Nhasi tichataura nezve pfungwa dze nitrogen yakazara, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, uye Kaishi nitrogen. Total nitrogen (TN) chiratidzo chinowanzo shandiswa kuyera huwandu hwezvinhu zvenitrogen zviri mumvura. Inosanganisira ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, uye zvimwe zvinhu zvenitrogen, senge nitrate midzi uye nitrate. Ammonia (NH3-N) inoreva kuwanda kweammonia (NH3) uye ammonia oxides (NH4+). Iyo haina kusimba alkaline nitrogen uye inogona kubatwa kuburikidza neiyo biological uye kemikari kuita mumuviri wemvura. Nitral nitrogen (NO3 -N) inoreva kuwanda kwemidzi ye nitrate (NO3-). Iyo yakasimba asidhi nitrogen, iyo ndiyo huru fomu ye nitrogen. Inogona kubva kune biological chiitiko cheammonia nitrogen uye organic nitrogen mumuviri wemvura. Nitric nitrogen (NO2 -N) inoreva kuwanda kwe nitrite midzi (NO2 -). Iyo isina kusimba acidic nitrogen, inotangira ye nitrate nitrogen, uye inogona kubva kune biological uye kemikari kuita mumuviri wemvura. Kjeldahl-N inoreva huwandu hweammonia oxides (NH4+) uye organic nitrogen (NORG). Iyo imhando yeammonia nitrogen inogona kubva kune biological uye kemikari maitiro mumuviri wemvura.
Nitrogen mumitumbi yemvura chikamu chakakosha, chinogona kukanganisa kunaka kwemvura, mamiriro ezvakatipoteredza emuviri wemvura, uye kukura nekuvandudzwa kwemvura biology. Nokudaro, kutarisa uye kutonga kwe nitrogen yakazara, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, uye Kaishi nitrogen mumuviri wemvura inokosha zvikuru. Izvo zviri mukati meiyo nitrogen chiratidzo chakakosha chekuyera huwandu hwese hwenitrogen zvinhu mumvura yemvura. Kazhinji, iyo yakazara nitrogen yemukati mumvura yemvura inofanira kunge iri mukati mehumwe huwandu. Kuwedzera kana kuderera zvakanyanya kunokanganisa kunaka kwemvura yemuviri wemvura. Pamusoro pezvo, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, uye Kaifer nitrogen zvakare zviratidzo zvakakosha zvekuona zvinhu zvenitrogen mumvura. Zvinyorwa zvavo zvinofanirawo kukanganisa hutano hwemvura yemuviri wemvura mukati meimwe nzvimbo.
Parizvino, nyika zhinji dzine mirau yakasimba pamusoro pehuwandu hwenitrogen, ammonia, nitrate nitrogen, nitrite nitrogen, uye Kaifer nitrogen mumitumbi yemvura. Migumisiro yakakomba. Naizvozvo, munhu wese anofanirwa kutarisisa kutarisisa uye kutonga kwezvinhu zvenitrogen mumvura yemvura kuti ave nechokwadi chekuti mhando yemvura yemuviri wemvura inosangana nezviyero zvehurumende. Zvese mune zvese, yakazara nitrogen, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, uye Kaifel nitrogen zviratidzo zvakakosha zve nitrogen zvinhu zviri mumvura. Zviri mukati mavo chiratidzo chakakosha chekuyera kunaka kwemvura, izvo zvakakosha pakutarisa nekudzora. Chete kuburikidza nekutarisa zvine musoro uye kutonga kwezvinhu zve nitrogen mumvura yemvura tinogona kuve nechokwadi chekuti mhando yemvura yemuviri wemvura inosangana neyakajairwa uye inodzivirira hutano hwemuviri wemvura.
Iyo Lianhua mhando yakagadzira midziyo yekuona yemhando yemvura kwemakore makumi mana. Inogona kupa zvigadzirwa zvekuona neammonia nitrogen, yakazara nitrogen, nitrogen nitrate, uye nitrate nitrogen nitrogen.
