Vim li no, cov teb chaws thoob plaws ntiaj teb tau sim ntau txoj hauv kev, xav ua kom tau txais kev txuag hluav taws xob thiab txo qis emissions, thiab kho lub ntiaj teb ib puag ncig.
Nyob rau hauv lub siab los ntawm txheej mus rau txheej, dej phwj nroj tsuag, raws li loj zog neeg siv, yog ib txwm ntsib transformation:
Piv txwv li, ntxiv dag zog rau kev ua haujlwm ntawm cov pa phem txo qis thiab koom nrog kev tshem tawm cov nitrogen thiab phosphorus heev;
Piv txwv li, txhawm rau txhim kho lub zog ntawm tus kheej-sufficiency tus nqi kom ua tiav cov txheej txheem kho dua tshiab thiab hloov pauv kom ua tiav cov dej phwj tuaj qis;
Piv txwv li, kev saib xyuas yuav tsum tau them rau cov peev txheej rov qab los ntawm cov txheej txheem ntawm kev kho cov dej phwj tuaj kom ua tiav cov khoom siv rov ua dua tshiab.
Yog li ntawd muaj:
Xyoo 2003, lub ntiaj teb thawj NeWater reclaimed water plant tau tsim nyob rau hauv Singapore, thiab rov siv cov dej phwj tuaj txog cov qauv dej haus;
Xyoo 2005, Austrian Strass dej phwj kho cog tau ua tiav lub zog ntawm tus kheej txaus rau thawj zaug hauv ntiaj teb, tsuas yog tso siab rau kev rov qab los ntawm cov tshuaj siv hluav taws xob hauv cov dej phwj tuaj kom tau raws li kev siv lub zog ntawm cov dej phwj tuaj;
Hauv xyoo 2016, Swiss txoj cai tswjfwm kev rov qab los ntawm cov khoom siv tsis muaj phosphorus rov qab los ntawm cov dej phwj tuaj (sludge), tsiaj quav quav thiab lwm yam pa phem.
…
Raws li lub ntiaj teb kev lees paub lub zog txuag dej, lub Netherlands yeej tsis nyob deb.
Yog li niaj hnub no, tus editor yuav tham nrog koj txog yuav ua li cas cov kav dej phwj tuaj hauv Netherlands tau hloov kho thiab hloov pauv hauv lub sijhawm ntawm carbon neutrality.
Lub tswv yim ntawm cov dej khib nyiab hauv Netherlands - lub moj khaum ntawm NEWs
Lub Netherlands, nyob rau hauv lub delta ntawm Rhine, Maas thiab Scheldt, yog thaj av qis.
Raws li ib tug environmentalist, txhua zaus kuv hais Holland, thawj yam uas tshwm sim hauv kuv lub siab yog Delft University of Technology.
Tshwj xeeb, nws Kluvyer Biotechnology Laboratory yog lub ntiaj teb nto moo rau nws cov kev ua tiav hauv microbial engineering technology. Ntau yam ntawm cov dej phwj tuaj kho cov thev naus laus zis peb paub tam sim no los ntawm no.
Xws li denitrification phosphorus tshem tawm thiab phosphorus rov qab (BCFS), luv luv-ntau nitrification (SHARON), anaerobic ammonium oxidation (ANAMMOX / CANON), aerobic granular sludge (NEREDA), sab kwj enrichment / mainstream enhanced nitrification (BABE), biological yas ( PHA) recycling, thiab lwm yam.
Dab tsi ntxiv, cov thev naus laus zis no kuj tau tsim los ntawm xibfwb Mark van Loosdrecht, uas nws yeej "Nobel nqi zog" hauv kev lag luam dej - Singapore's Lee Kuan Yew Water Prize.
Ntev dhau los, Delft University of Technology tau tshaj tawm lub tswv yim ntawm kev kho dej phwj tuaj. Xyoo 2008, Lub Netherlands Applied Water Research Foundation tau tsim lub tswv yim no rau hauv "Xov Xwm" lub hauv paus.
Ntawd yog, cov lus luv luv ntawm cov kab lus Nutrient (nutrient) + Zog (zog) + Dej (dej) factories (lub Hoobkas), uas txhais tau hais tias cov dej phwj tuaj kho raws li lub tswv yim ruaj khov yog qhov tseeb trinity ntau lawm Hoobkas ntawm cov as-ham, lub zog thiab rov ua dua tshiab. dej.
Nws tsuas yog tshwm sim hais tias lo lus "NEWs" kuj muaj lub ntsiab lus tshiab, uas yog lub neej tshiab thiab yav tom ntej.
Qhov no "XOV XWM" zoo npaum li cas, nyob rau hauv nws lub moj khaum, yuav luag tsis muaj pov tseg hauv kev xav hauv cov dej phwj tuaj:
Organic teeb meem yog cov khoom siv hluav taws xob, uas tuaj yeem siv los ua kom lub zog siv ntawm kev ua haujlwm thiab ua tiav lub hom phiaj ntawm kev ua haujlwm ntawm cov pa roj carbon monoxide; cov cua kub uas muaj nyob rau hauv cov dej phwj tuaj yeem hloov pauv mus rau ntau qhov kub / txias zog los ntawm cov dej hauv cov twj tso kua mis, uas tuaj yeem tsis tsuas yog ua rau cov pa roj carbon-tsis zoo, tab sis kuj muaj peev xwm xa tawm cua sov / txias rau tib neeg. Qhov no yog qhov chaw cog hluav taws xob hais txog.
Cov khoom noj khoom haus hauv cov dej phwj tuaj, tshwj xeeb tshaj yog phosphorus, tuaj yeem rov qab zoo thaum lub sijhawm kho, txhawm rau ncua qhov tsis muaj phosphorus cov peev txheej mus rau qhov loj tshaj. Qhov no yog cov ntsiab lus ntawm lub Hoobkas khoom noj khoom haus.
Tom qab kev rov qab los ntawm cov organic teeb meem thiab cov as-ham tiav lawm, lub hom phiaj tseem ceeb ntawm kev kho cov dej phwj tuaj yeem ua tiav, thiab cov peev txheej ntxiv yog cov dej rov qab uas peb tau paub. Qhov no yog dab tsi reclaimed water plant yog hais txog.
Yog li ntawd, lub Netherlands kuj tau sau cov txheej txheem ntawm kev kho dej phwj tuaj rau hauv rau 6 txheej txheem loj: ①pretreatment; ② kev kho mob yooj yim; ③ kev kho mob tom qab; ④ kev kho sludge;
Nws zoo nkaus li yooj yim, tab sis qhov tseeb muaj ntau yam thev naus laus zis los xaiv tom qab txhua kauj ruam txheej txheem, thiab tib lub thev naus laus zis kuj tuaj yeem siv rau hauv cov txheej txheem sib txawv, ib yam li kev hloov pauv thiab kev sib txuas, koj tuaj yeem nrhiav txoj hauv kev zoo tshaj plaws los kho cov dej phwj tuaj.
Yog tias koj xav tau cov khoom saum toj no los kho ntau yam dej phwj tuaj, thov hu rau peb.
