Stage 3 : Nitrification Qhov thib peb, nitrification, kuj tshwm sim hauv av. Thaum lub sij hawm nitrification cov ammonia nyob rau hauv cov av, tsim thaum lub sij hawm mineralization, yog hloov dua siab tshiab rau hauv lub tebchaw hu ua nitrites, TSIS MUAJ2 -, thiab nitrates, TSIS MUAJ. 3- Nitrates siv tau los ntawm cov nroj tsuag thiab tsiaj txhu uas haus cov nroj tsuag.
Nitration yog dab tsi hauv lub voj voog nitrogen?
Nitrification yog txheej txheem uas hloov ammonia rau nitrite thiab tom qab ntawd mus rau nitratethiab yog lwm kauj ruam tseem ceeb hauv ntiaj teb nitrogen voj voog. Feem ntau nitrification tshwm sim aerobically thiab yog nqa tawm tsuas yog los ntawm prokaryotes.
5 theem ntawm lub voj voog nitrogen yog dab tsi?
Feem ntau, lub voj voog nitrogen muaj tsib kauj ruam:
- Nitrogen fixation (N2 rau NH3 / NH4+ lossis NO3-)
- Nitrification (NH3 to NO3-)
- Assimilation (Kev koom ua ke ntawm NH3 thiab NO3- rau hauv cov ntaub so ntswg lom)
- Ammonification (organic nitrogen tebchaw rau NH3)
- Denitrification(NO3- to N2)
Nitrification tshwm sim dab tsi?
Nitrification yog biological oxidation ntawm ammonia rau nitrite tom qab oxidation ntawm nitrite rau nitrate tshwm simlos ntawm cov kab mob sib cais lossis ncaj qha ammonia oxidation rau nitrate hauv cov kab mob comammox. Kev hloov pauv ntawm ammonia rau nitrite feem ntau yog tus nqi txwv cov kauj ruam ntawm nitrification.
4 theem ntawm lub voj voog nitrogen yog dab tsi?
Teb: Lub voj voog nitrogen yog theem rov ua dua ntawm cov nitrogen uas suav nrog nitrogen fixation, ammonification, nitrification, thiab denitrification.
