Raws li cov khoom siv tseem ceeb tshaj plaws hauv tib neeg kev tsim khoom thiab qhov tsim nyog hauv lub neej niaj hnub, cov peev txheej dej tau raug kev puas tsuaj uas tsis tau muaj dhau los nrog kev nrawm ntawm cov txheej txheem kev lag luam.Kev tiv thaiv thiab kev kho cov khoom siv dej tau mus txog qhov xwm txheej ceev.Cov pa phem ntawm cov peev txheej dej feem ntau yog los ntawm kev tso dej ntawm cov dej hauv kev lag luam, nrog rau kev tso tawm loj ntawm ntau yam kev tsim khoom thiab cov kav dej hauv tsev hauv nroog.Nyob rau tib lub sijhawm, cov kev xav tau rau kev ua haujlwm ntawm ntau yam khoom siv kho dej phwj tuaj, thiab kev saib xyuas cov dej phwj tuaj kho dej kom zoo thiab cov dej ntim tau kuj nce siab dua.
Cov chaw kho dej phwj tuaj thoob ntiaj teb tso siab rau Sinomeasure kev ntsuas thev naus laus zis vim tias lawv tso qhov tseem ceeb ntawm cov nroj tsuag siab, kev ua haujlwm tsis muaj kev saib xyuas thiab ntsuas cov ntaub ntawv raug, ua lub hauv paus rau kev tswj tsis siv neeg ntawm ntau yam txheej txheem.
- Bar screen
Lub vijtsam bar yog lub tshuab lim siv los tshem tawm cov khoom loj, xws li rags thiab plastics, los ntawm cov dej khib nyiab.Nws yog ib feem ntawm cov thawj filtration flow thiab feem ntau yog thawj, los yog ua ntej, theem pom, raug ntsia ntawm lub zog rau cov dej khib nyiab.Lawv feem ntau muaj cov kab ntsug steel kab sib nrug ntawm 1 thiab 3 nti sib nrug.
- Kev tshem tawm Grit
Grit particles uas me dua qhov aperture ntawm lub vijtsam yuav dhau mus thiab ua rau muaj teeb meem abrasive ntawm cov kav dej, twj thiab cov khoom siv sludge.Cov grit hais tuaj yeem nyob hauv cov kab, aeration tank pem teb thiab sludge digestors uas tuaj yeem tsim teeb meem txij nkawm.Yog li ntawd, ib qho kev tshem tawm grit yog xav tau rau feem ntau cov chaw kho dej phwj.
- Cov ntsiab lus meej
Clarifiers yog tso cov tso tsheb hlau luam tsim nrog cov cuab yeej siv rau kev tshem tawm tas li ntawm cov khib nyiab uas tau tso los ntawm sedimentation.Cov ntsiab lus tseem ceeb txo cov ntsiab lus ntawm cov khoom raug tshem tawm thiab cov pa phem uas nyob hauv cov khoom raug tshem tawm
- Aerobic systems
Kev kho cov dej khib nyiab los yog ntxiv polishing ntawm pretreated wastewater Aerobic kev kho mob yog cov txheej txheem dej khib nyiab lom neeg uas tshwm sim thaum muaj oxygen.Aerobic biomass hloov cov organic hauv dej khib nyiab rau hauv carbon dioxide thiab biomass tshiab.
- Anaerobic systems
Anaerobic digestion yog ib txheej txheem uas cov kab mob hloov cov organic teeb meem rau hauv biogas thaum tsis muaj oxygen kev kho mob Anaerobic feem ntau yog siv los kho sov, muaj zog muaj zog cov dej khib nyiab uas muaj siab concentrations biodegradable organic teeb meem.Cov txheej txheem txuag hluav taws xob no tso siab tau tshem tawm biochemical oxygen xav tau (BOD), tshuaj lom neeg oxygen xav tau (COD), thiab tag nrho cov khib nyiab tshem tawm (TSS) los ntawm cov dej khib nyiab.
- Secondary clarifier
Clarifiers yog tso cov tso tsheb hlau luam tsim nrog cov cuab yeej siv rau kev tshem tawm tas li ntawm cov khib nyiab uas tau tso los ntawm sedimentation.Secondary clarifiers tshem tawm flocs ntawm lom kev loj hlob tsim nyob rau hauv ib co txoj kev ntawm kev kho mob theem nrab nrog rau activated sludge, trickling filters thiab rotating lom contactors
- Tshuaj tua kab mob
Cov txheej txheem kho aerobic txo cov kab mob, tab sis tsis txaus kom tsim nyog raws li cov txheej txheem tshuaj tua kab mob.Chlorination / dechlorination tau siv dav siv tshuaj tua kab mob hauv ntiaj teb, ozonation thiab UV teeb yog cov thev naus laus zis tshiab.
- Tso tawm
Thaum cov dej phwj kho tau raws li lub teb chaws lossis hauv cheeb tsam cov dej phwj tuaj, nws tuaj yeem tso tawm rau hauv dej los yog txheeb xyuas cov hauv kev los tiv thaiv lossis txo cov dej qias neeg los ntawm kev ntsuas xws li rov siv dua / rov siv dua hauv lawv qhov chaw, kev hloov pauv hloov.
