Tam sim no, dav spectrum ntawm physico-tshuaj technologies rau kev tshem tawm nitrogen los ntawm cov dej khib nyiab muaj: ammonia cua thiab chav stripping; ammonia nqus tsev distillation; ammonia nag lossis daus li struvite; tshem tawm ammonia thiab nitrate los ntawm kev xaiv ion txauv; breakpoint chlorination; Kev tshem tawm chloramine los ntawm…
Ammoniacal nitrogen tshem tawm ntawm cov dej khib nyiab li cas?
Txoj kev lom neeg kom tshem tawm cov ammonical nitrogen yog los ntawm nitrification thiab denitrification txheej txheem thiab tseem tshiab ANNAMOX txheej txheem. Raws nraim qhov teeb meem ntawm qhov loj yog qhov, Koj tsis tuaj yeem nce pH tshaj 7.5 txhawm rau txhawm rau txhawm rau ammonia los ntawm kev hloov cov dej khib nyiab pH rau alkalinity.
Yuav ua li cas nitrogen tshem tawm ntawm cov dej khib nyiab?
Nws muaj ob kauj ruam rau kev tshem tawm nitrogen hauv kev kho mob lom: nitrification thiab denitrification. Hauv cov txheej txheem no, nitrifiers, suav nrog cov kab mob ammonia-oxidizing (AOB) thiab cov kab mob nitrite-oxidizing (NOB), hloov tag nrho ammonia (dawb ammonia thiab un-ionized ammonia) rau nitrate.
txheej txheem rau kev tshem tawm nitrogen yog dab tsi?
Kev tshem tawm cov nitrogen lom yog ua tiav los ntawm nrawm nitrification nyob rau hauv aerobic tej yam kev mobthiab denitrification nyob rau hauv anoxic mob. Thaum lub sij hawm nitrification, ammonium yog oxidized rau nitrite los ntawm ammonium oxidizing kab mob (AOB) thiab ces rau nitrate los ntawm nitrite oxidizing kab mob (NOB).
HowPuas yog nitrogen tshem tawm ntawm huab cua?
Muaj peb txoj hauv kev siv los rho tawm nitrogen los ntawm huab cua hauv qab no: Cryogenic distillation . Nias viav vias adsorption . Kuv teb …..
- Feed filter coalescers.
- Immersion heaters.
- Activated carbon filters.
- Particulate filters.
