Vim li no, cov teb chaws thoob plaws ntiaj teb tau sim ntau txoj kev siv tshuab, xav ua kom txuag hluav taws xob thiab txo cov pa phem, thiab kho lub ntiaj teb ib puag ncig.
Nyob rau hauv kev nyuaj siab los ntawm txheej mus rau txheej, cov chaw lim dej, ua cov neeg siv hluav taws xob loj, tab tom ntsib kev hloov pauv ntuj tsim:
Piv txwv li, txhawb zog rau kev ua haujlwm ntawm kev txo cov pa phem thiab koom nrog kev tshem tawm nitrogen thiab phosphorus ntau heev;
Piv txwv li, txhawm rau txhim kho tus nqi ntawm kev siv hluav taws xob kom txaus los ua kom muaj kev txhim kho thiab kev hloov pauv tus qauv kom ua tiav kev kho dej phwj uas tsis muaj carbon ntau;
Piv txwv li, yuav tsum tau them sai sai rau kev rov qab siv cov peev txheej hauv cov txheej txheem ntawm kev kho dej phwj kom ua tiav kev rov ua dua tshiab.
Yog li ntawd muaj:
Xyoo 2003, lub ntiaj teb thawj lub chaw tsim dej rov qab NeWater tau tsim tsa hauv Singapore, thiab kev siv dej phwj rov qab dua tau mus txog cov qauv dej haus;
Xyoo 2005, lub chaw kho dej phwj Austrian Strass tau ua tiav kev siv hluav taws xob rau tus kheej thawj zaug hauv ntiaj teb, tsuas yog vam khom kev rov qab los ntawm lub zog tshuaj lom neeg hauv dej phwj kom tau raws li kev siv hluav taws xob ntawm kev kho dej phwj;
Xyoo 2016, txoj cai lij choj Swiss tau yuam kom rov qab tau cov khoom siv phosphorus uas tsis rov ua dua tshiab los ntawm cov dej phwj (sludge), cov quav tsiaj thiab lwm yam kuab paug.
...
Ua ib lub teb chaws uas paub txog kev txuag dej thoob ntiaj teb, Netherlands yeej tsis poob qab li.
Yog li hnub no, tus editor yuav nrog koj tham txog seb cov chaw lim dej hauv Netherlands tau hloov kho dua tshiab thiab hloov pauv li cas 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 ib thaj av qis.
Ua ib tug neeg tiv thaiv ib puag ncig, txhua zaus kuv hais txog Holland, thawj qhov uas tshwm sim hauv kuv lub siab yog Delft University of Technology.
Tshwj xeeb, nws lub Kluvyer Biotechnology Laboratory yog lub ntiaj teb nto moo rau nws cov kev ua tiav hauv kev siv tshuab microbial engineering. Ntau yam ntawm cov thev naus laus zis kho dej phwj uas peb paub tam sim no los ntawm no.
Xws li kev tshem tawm phosphorus denitrification thiab phosphorus rov qab los (BCFS), nitrification luv luv (SHARON), anaerobic ammonium oxidation (ANAMMOX/CANON), aerobic granular sludge (NEREDA), side stream enrichment/mainstream enhanced nitrification (BABE), biological Plastic (PHA) recycling, thiab lwm yam.
Tsis tas li ntawd xwb, cov thev naus laus zis no kuj tau tsim los ntawm Xibfwb Mark van Loosdrecht, uas nws yeej qhov khoom plig "Nobel" hauv kev lag luam dej - Singapore's Lee Kuan Yew Water Prize.
Ntev dhau los lawm, Delft University of Technology tau tawm tswv yim txog kev kho cov dej phwj kom ruaj khov. Xyoo 2008, lub koom haum Netherlands Applied Water Research Foundation tau muab lub tswv yim no rau hauv lub moj khaum "NEWs".
Ntawd yog, cov lus luv ntawm cov kab lus Nutrient (nutrient) + Energy (energy) + Water (water) factories (factory), uas txhais tau tias lub chaw kho dej phwj tuaj raws li lub tswv yim ruaj khov yog qhov tseeb yog lub Hoobkas tsim khoom trinity ntawm cov as-ham, lub zog thiab dej rov ua dua tshiab.
Nws tsuas yog tshwm sim tias lo lus "NEWs" kuj muaj lub ntsiab lus tshiab, uas yog lub neej tshiab thiab yav tom ntej.
Qhov "NEWs" no zoo npaum li cas, nyob rau hauv nws lub moj khaum, yuav luag tsis muaj pov tseg hauv kev nkag siab ib txwm muaj hauv cov dej phwj tuaj:
Cov khoom siv organic yog tus nqa lub zog, uas tuaj yeem siv los ua kom tau raws li kev siv zog ntawm kev ua haujlwm thiab ua tiav lub hom phiaj ntawm kev ua haujlwm tsis muaj carbon; qhov kub uas muaj nyob hauv cov dej phwj tuaj yeem hloov pauv mus ua ntau lub zog cua sov / txias los ntawm lub twj tso kua dej kub, uas tsis yog tsuas yog pab txhawb rau kev ua haujlwm tsis muaj carbon xwb, tab sis kuj muaj peev xwm xa tawm cua sov / txias mus rau zej zog. Qhov no yog qhov chaw tsim hluav taws xob yog hais txog.
Cov as-ham hauv cov dej phwj tuaj yeem rov qab tau zoo thaum lub sijhawm kho, yog li ntawd thiaj li ncua qhov tsis muaj phosphorus ntau tshaj plaws. Qhov no yog cov ntsiab lus ntawm lub Hoobkas as-ham.
Tom qab ua tiav kev rov qab tau cov organic thiab cov as-ham, lub hom phiaj tseem ceeb ntawm kev kho dej phwj tuaj yeem ua tiav, thiab cov peev txheej seem yog cov dej rov qab uas peb paub zoo. Qhov no yog lub tshuab ua dej rov qab.
Yog li ntawd, Netherlands kuj tau muab cov kauj ruam ntawm kev kho dej phwj tuaj ua rau rau qhov txheej txheem tseem ceeb: ① kev kho ua ntej; ② kev kho yooj yim; ③ kev kho tom qab; ④ kev kho sludge;
Nws zoo li yooj yim, tab sis qhov tseeb muaj ntau yam thev naus laus zis xaiv los ntawm txhua kauj ruam ntawm cov txheej txheem, thiab tib lub thev naus laus zis kuj tseem tuaj yeem siv rau hauv cov kauj ruam sib txawv, ib yam li kev hloov pauv thiab kev sib xyaw ua ke, 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, thov hu rau peb.
