Cov lus qhia: Kab lus no tham txog "Anammox roj ntsha nitrogen tshem cov txheej txheem." Cov txheej txheem nitrogen tshem tawm tau siv hauv cov khoom siv pov tseg hauv kev kho kom me nyuam yaus txij li xyoo 2002, tab sis nws cov nyiaj saws me nyuam tsawg heev; Nws yog qhov nyuaj kom nrhiav tau ntau cov nroj tsuag pov tseg cov ntoo hauv Suav teb siv cov thev naus laus zis no. Los ntawm nws cov hauv paus ntsiab lus, peb tuaj yeem pom qhov piv tau ntawm Nitrification thiab tsis muaj ob qho kev siv hluav taws xob, nws muaj kev xav tau cov pa roj carbon monoxide) thiab tsis tas yuav muaj cov pa roj carbon monoxide Siv cov txheej txheem no tuaj yeem txo cov nqi tshem tawm nitrogen tshem tawm.
I. Cov ntsiab cai ntawm Anammox
Kev Txhais Lus: Anammox tshuab ua yog hailed raws li kev tawm tsam kev tawm tsam hauv kev kho kom muaj kev kho kom muaj kev kho kom muaj kev kho kom zoo dua thaum pib ntawm 21st caug xyoo. Nws siv tshwj xeeb hom ntawm autotrophic bacteria-}}}} {4 4}} kev txwv tsis pub muaj nitrogen tshem tawm. Tus txheej txheem no Openn Nitrification Nitration-}}}} Yuav tsum tau muaj cov pa oxygen loj thiab cov organic carbon.
Tub ntxhais lub hauv paus ntsiab lus:
Cov tseem ceeb tshuaj lom neeg: Nh₄⁺ + Nou → n n + 2 h₂o. Anaerobic ammonia oxidizing kab mob ncaj qha "Txuas" Ammonia thiab nitrite los tsim kev tsis muaj kev phom sij nitrogen g ammonia nitrogen rau nitrate thiab tom qab ntawd txo nws.
Kev txhim kho ntawm lub cev ua haujlwm: Cov kab mob hauv lub ntiaj teb no siv cov pa roj carbon monoxide / h.cing) los ntawm cov pa roj carbon monoxide (xws li muab cov pa roj carbon monoxide
Qhov tseem ceeb txuag nyiaj: piv rau cov txheej txheem tsoos), nws tuaj yeem txuag tau li 60% ntawm cov organic carbon chaw (100% ntawm cov organic carbon chaw (100% ntawm cov organic carbon ntau (tsis xav tau cov organic carbon paus), thiab txo cov organic carbon paus (100% ntawm cov organic carbon chaw (100% ntawm cov organic carbon paus (100% ntawm cov organic carbon paus (100% ntawm cov organic carbon paus (100% ntawm cov khoom siv roj carbon monoxent), 100% ntawm cov organic carbon ntau dua (tsis xav tau cov organic carbon monoxent), thiab txo cov organic carbon ntau dua (tsis xav tau cov organic carbon ntau dua), thiab txo qis dua sludge ntau lawm los ntawm txog 90%.
Ii. Kev siv tej yam kev mob thiab cov nyom ntawm cov nyom
Kev tswj hwm kev tswj hwm:
Cov khoom noj nitrite nitrite: ib feem ntawm ammonia nitrogen yuav tsum tau precisly {{le {le {le {cut nitrification) los tswj hwm lub zog tsis muaj zog (feem ntau<30 mg/L). Excessive levels will inhibit bacterial activity, while insufficient levels will result in inadequate reaction.
Zoo diam oxygen (ua) tswj: lub zos anroenolironment (ua kom zoo nkauj rau cov kab mob muaj sia nyob thaum ua kom muaj kev ciaj sia ntawm cov kab mob.
Qhov kub yuav tsum tau: Zoo tshaj 30-40 degree. Tsawg kub (<15°C) will significantly reduce bacterial activity and increase operational difficulty.
Cov dej ua haujlwm zoo: nkag siab cov tshuaj lom (xws li hlau hnyav, cov organic teeb meem, thiab cov sulfides (SS) cov ntsiab lus.
Txheej Txheem Siv Cov Kev Sib Tw:
Kev pib qeeb qeeb -} up: anammox cov kab mob muaj lub sijhawm ntev (kwv yees li 11 hnub) thiab tseem ntev dua rau cov reactor pib-up.
Tsis yooj yim sludge khaws cia: Cov qauv tsim tshwj xeeb (xws li cov tshuab hluav taws xob tshwj xeeb (xws li biofilm system) yuav tsum tau tuav kom tau qeeb {{} {}} loj} loj hlob rau cov kab mob anammox.
Cov txheej txheem sib txuas ua ke txuas: me me ua tiav luv {{luas nws nrog ib qho kev sib cav sib ceg (muab cov txheej txheem tsis zoo) yog qhov kev sib tw theem ntawm engineering.
Tsis muaj zog tsis kam rau kev poob siab: tsis kam rau kev hloov pauv hauv cov dej tsis zoo, ntau, ua haujlwm muaj kev ua haujlwm nyuaj.
III. Cov neeg sawv cev ntawm cov ntawv thov tam sim no ntawm cov thev naus laus zis no
** DOKHAVEN KHWV COG, ROTTERDAM, Netherlands (Lub ntiaj teb no}}}}- 2002 Ua tiav kev khiav haujlwm tau ntau xyoo, nws sawv cev rau lub peev xwm hauv kev tsim thev naus laus zis.
** Kev kho kom muaj khib nyiab tshem tawm, Austria: ** Ib lub zog thoob ntiaj teb {{}}}} txaus lim dej kho cov nroj tsuag. Nws sab -} dem dem dem dem dem dem process ® process ® process ® process ® dig dig Dotection, txo cov nroj tsuag ua tiav ntau dua 100% 5}} kev pab muaj txiaj ntsig.
** Cov dej rov qab cog qoob loo, Singapore: ** Loj - Cov txheej txheem ndauv los kho sludge digestate, txhim kho kev txhim kho kev ua tau zoo, txhim kho kev txhim kho kev ua tau zoo thiab ruaj khov.
** Gaobeidian reclaimed dej cog, Beijing, Suav: ** Ib qho ntawm cov khoom siv lim dej ntxov (cov txheej txheem dab neeg lim dej.
Huaai Fang Reclaimed dej cog hauv Beijing, Suav, siv AnammoS txheej txheem raws MBRB los kho sludge zom zom cov kua dej tom qab thermal hydrolysis.
IV. Kev soj ntsuam ntawm cov laj thawj rau kev txwv thiab qib siab?
Txawm hais tias nws cov txiaj ntsig tseem ceeb, cov ntawv thov tiag tiag ntawm Anaerobic Ammonia oxidation (Anao) tseem nyob hauv kev kho kom zoo nkauj. Cov laj thawj tseem ceeb muaj raws li hauv qab no:
1. Cov kev tswj hwm cov txheej txheem siab heev thiab muaj kev nkag siab rau cov pa roj av zoo xws li cov pa roj carbon monection, thiab kub thiab kub thiab kub thiab txias. Kev ua haujlwm thiab kev saib xyuas xav tau cov kws ua haujlwm muaj tswv yim.
2. Cov tshuaj reactors tshwj xeeb yuav tsum rau cov microbial txhawb nqa thiab sludge letterent (xws li granular sludge txaj thiab MBBRS) muaj qhov nqi peev txheej loj.
3. Tsis muaj kev tsim qauv thiab muaj feem nrog kev ua haujlwm: piv rau lub xyoo pua-} Technology tau tsuas yog siv nyob rau hauv cov ntawv thov engineering tau li 20 xyoo. Cov qauv tsim qauv, cov phau ntawv qhia ua haujlwm, thiab daws teeb meem kev ua haujlwm databases nyob deb ntawm noob.
4. Nyuaj rau hauv kev tswj cov kev mob ib puag ncig rau cov microorganisms: cov chaw dej hauv lub caij ntuj sov (CODE Cov yam ntxwv no tau hloov siab los ntawm kev ua kom zoo tshaj plaws rau cov kab mob anammo povhwm, ua haujlwm nyuaj nyuaj.
5. Cia siab rau thiab ntseeg hauv cov txheej txheem kev ua haujlwm ib txwm muaj: kev tsim kho kom zoo, yooj yim rau kev nkag siab zoo, tsim kom muaj kev vam meej kev kawm, tsim kom muaj kev txhawb nqa hauv inertia. Tom qab tag nrho, ob peb yuav txiav txim siab abandoning tus txheej txheem mature rau ib qho tshiab, tshwj xeeb yog muab cov kev pheej hmoo peev tseem ceeb nrog.
