1 Cov hau kev yooj yim ntawm cov dej phwj
Kev Ua Haujlwm Lub Cev
Cov hau kev feem ntau siv rau cais cov khib nyiab, thiab cov khoom tawg, thiab cov khoom loj hauv cov dej khib nyiab los ntawm kev tawm dag zog lub cev muaj xws li:
Grille pom: cuam tshuam cov khoom loj xws li tsob ntoo ceg thiab cov tshuaj tua hluav taws yas los tiv thaiv txhaws ntawm cov cuab yeej txuas ntxiv.
Dag Zog Txheej Txheem: Siv Lub Zog Cua los daws cov khib nyiab tshem tawm mus rau hauv qab, xws li tshem tawm cov ntawv xuab zeb los ntawm lub tentimentation.
Huab cua Struction: Tso Npas Taws kom cov roj lossis cov khoom ntab ntab rau cov dej saum npoo av kom yooj yim sib cais.
Pom kev thiab adsorption: Siv cov xov xwm ntxeem xws li cov xuab zeb thiab ua kom cov pa roj av kom lim cov khoom me me.
Kev Kho Mob Kev Siv Tshuaj
Los ntawm kev ntxiv cov tshuaj tiv thaiv tshuaj los hloov cov khoom ntawm cov dej khib nyiab, cov pa phem tuaj yeem ua haujlwm lossis hloov chaw:
Coagulation nag lossis cov coagants xws li txhuas ntsev thiab hlau ntsev rau coagulate thiab nag lossis daus colloid.
Redox: Siv oxidants xws li ozone thiab chlorine mus rau decompose organic teeb meem lossis txo cov hlau hnyav.
Adsorption txoj kev: Ua kom tau cov pa roj carbon tshev thiab cov hlau hnyav.
Neutralization txoj kev: kho tus nqi pH thiab kho acidic lossis alkaline quav dej.
Kev Ua Dab Tsi
Siv cov metabolial microbolism micribism rau cov teeb meem orgetic thiab as-ham, kev lag luam thiab tus phooj ywg ib puag ncig:
Ua kom cov txheej txheem sludge: aation txhawb kev loj hlob ntawm cov kab mob me ntawm cov kab mob los ua cov sludge, uas decomposes organic teeb meem.
Kev qhia biofilm: Cov kab mob me me txuas nrog rau saum npoo ntawm cov fillers los ua biofilms, purifyewater.
Anaerobic kev zom zaub mov: nyob rau hauv Anaerobic tej yam kev mob, organic muaj teeb meem los ua roj xws li metrane.
2 tus txheej txheem txheem rau dej phwj kev kho
Preprocessing theem
Lub hom phiaj: Tshem tawm cov impurities loj thiab tiv thaiv cov khoom siv tom qab.
Cov kauj ruam:
Grille: Kev cuam tshuam cov khoom ntab (xws li yas, ntoo ceg).
Tawv lub tank (rau kev daws cov khoom hnyav xws li xuab zeb thiab pob zeb.
Cov pas dej tswj kav dej: Tshuav dej zoo thiab ntau kom ntseeg tau tias muaj peev xwm kho tau.
Thawj qib ua (kev ua haujlwm ntawm lub cev)
Lub Hom Phiaj: Tshem cov khib nyiab tshem tawm thiab qee qhov colloids.
Cov chaw ua haujlwm tseem ceeb: thawj lub taub hau tawb lub taub hau, uas siv lub ntiajteb txawj nqus los daws cov sludge, thiab tus supernatant nkag mus rau theem tom ntej.
Kev kho mob ob (kho mob)
Lub Hom Phiaj: Kom degrade organic teeb meem thiab txhim kho cov dej ua tau zoo.
Cov txheej txheem ntau yam:
Ua kom cov txheej txheem sludge: cov kab mob kab mob decompose decompose cov teeb meem organic thiab cais sludge nyob rau hauv ib lub tenimary shoulentation tank.
Cov qauv dej phwj biofilm: dej ntws los ntawm biofilms, uas cov microorganism denzre kuab paug.
Thib peb qib kev ua (kev ua siab sib sib zog)
Lub Hom Phiaj: Txhawm rau tshem tawm cov khoom siv hluav taws xob recalcitrant, nitrogen, phosphorus, thiab pathogens.
Cov txheej txheem nquag:
Coagulation nag lossis cov nag lossis cov khib nyiab seem.
ACCANATED cov pa roj carbon adsorption: Adsorbs lw kuab paug.
Ozone oxidation: decomposes recalcitrant organic.
Membrane sib cais: Cuam Tshuam Cov Kab Mob, Kab Mob, thiab lwm yam.
Kev tua kab mob thiab paug
Lub Hom Phiaj: Yuav kom tshem tawm pathogens thiab ua kom muaj kev nyab xeeb effluent.
Cov hau kev: chlorination, ultraviolet tshuaj tua kab mob, ozone kev kho mob.
Qhov kawg lo lus kawg: Ua tau raws cov qauv emission lossis rov siv dej rov qab, kev lag luam, thiab lwm yam.
Sludge kev kho thiab pov tseg
Lub Hom Phiaj: Kom tsis txhob muaj kuab paug ob thiab ua tiav kev siv Sludge cov peev txheej siv.
Txheej txheem: concermration, lub cev qhuav dej, kho kom haum, av av, lossis av siv (xws li chiv).
3 yam ntxwv ua thiab kev thov
Kev tsim lub cev: haum rau tshem tawm cov impurities loj, nrog tus nqi qis, nquag siv rau pretreatment.
Tshuaj lom neeg siv tshuaj: rau cov kuab paug uas hnyav xws li cov hlau hnyav thiab roj, cov tshuaj tiv thaiv yog kev nrawm tab sis yuav tsim cov khoom lag luam.
Kev kho mob biological: Tsim nyog rau kev ua haujlwm loj ntawm cov organic, nrog cov nqi ua haujlwm qis, tab sis yuav tsum tau tswj hwm qhov kub thiab txias, pH, thiab lwm yam kev mob.
