Kev Kho Mob ntawm Tsev Kho Mob Cov Khoom Siv Kom Siv Ua Haujlwm Sauv

Kev ua kom tau cov txheej txheem sludge tau yog tus nqi kho kom zoo siv tshuaj lim dej uas limies lim dej los ntawm cov haujlwm metabolic ntawm cov zej zog medabolic. Nws yog feem ntau sib xyaw nrog kev tua kab mob thiab qib kev kawm qib siab los khoTsev kho mob kom tau txais dej numCov. Yog li, peb yuav tsim qauv no kom ua tiav tau zoo dua? Nyeem rau tshawb txog cov ncauj lus no nrogPas dej.

Tsis zoo li cov dej phwj tuaj zoo ib yam nkaus, lub tsev kho mob muaj teeb meem tsis muaj teeb meem tshwj xeeb xws li pathogenic microorganisms, chaw seem ntawm cov tshuaj, thiab tshuaj lom neeg. Cov txheej txheem no yog los ntawm tus neeg mob excreta, phais pov khib, lossis kuaj sim kuaj. Cheebtsam no muab cov yam ntxwv ua haujlwm hauv tsev kho mob zoo li:
• Cov kev pauv tseem ceeb hauv dej zoo thiab ntau, cuam tshuam los ntawm tsev kho mob cov sijhawm ua haujlwm
• Qee yam khoom siv yog qhov nyuaj rau cov kab mob me los decompose
• Muaj peev xwm lom neeg lom zem
• Muaj tshuaj lom neeg cov pa oxygen (COD) thiab biochemical cov pa oxygen thov (bod)

Feem ntau, kev kho kom zoo rau hauv tsev kho mob Kstewater kev kho mob muaj peb theem kev kho mob loj: kev kho mob, thiab kev kho mob siab heev Thaum lub sij hawm pretreatment theem, ib lub grille yog ntsia ntawm qhov inlet los cuam tshuam cov khoom sib txuam loj, thiab ib grit chamber kom tshem tawm cov dej phwj tuaj. Vim yog cov yam ntxwv biochemical ntawm lub tsev kho mob dej huv, cov theem no tseem yuav tsum muaj kev ntsuas kev tshem tawm ntxiv, suav nrog cov chlorination, ultraviolet (UV) kev tua kab mob, thiabOzone Kev Kho Mobmus tua pathogens.

Tom ntej no, hauv cov txheej txheem kev kho ntsha ua roj ntsha, ntsaws cov pa dej AERATERdiffusersLos yog ua ntu zus batch reactors (SBR) ua haujlwm. Tus qub tsim kev pom zoo ntawm txoj kev txhim kho hauv kev txhim kho kev tsim qauv, pub cov kab mob sib txawv kom loj hlob hauv cov chaw sib txawv thiab cov zej zog sib txawv. Nyob rau hauv ib qho sbr system, cov txheej txheem xws li aeration thiab sedimentation yog nqa tawm ua ntu zus nyob rau hauv ib reactor. Txoj kev mus ze no tuaj yeem cuam tshuam ntau dua Cod, nrog rau Nitrogen thiab Phosphorus Cheebtsam.

Thaum lub sij hawm sludge sludge tom qab, nws yog ib qho tsim nyog los tswj cov sludge rov qab piv, raws li kev rov qab rov qab tuaj yeem tswj hwm qhov kev xav hauv lub nroog Aerer. Tsev kho mob kom muaj zog ntau zaus muaj cov qauv tsis zoo tsim nyog yuav tsum ua kom cov dej khib nyiab rau hauv cov khoom siv Aereration. Qhov no pab txo qhov poob siab thauj khoom ntawm cov kab mob me thiab tswj kev nrawm nrawm.

Chaw nyob seem

 

Tsoos qhib cov txheej txheem sludge tawm tsam rau uniformly tshem tawm ntau cov tshuaj tua kab mob, xws li -lactam tshuaj tua kab mob thiab sulfonamides. Nyob rau hauv cov xwm txheej zoo li no, txuas ntxiv rau lub hnub nyoog sludge tuaj yeem sim ua kom muaj ntau cov kab mob ua kom tawg cov tshuaj tua kab mob. Hloov pauv, cov txuj ci ua tiav qib siab tau siv tau los rhuav tshem cov tshuaj loj hauv nruab nrab uas tau yooj yim dua biodegradable.

Turboid effluent

 

Cov xwm txheej no feem ntau tshwm sim los ntawm ntau cov kab mob muaj filamentous remamentous kev loj hlob. Nce kev siv ntawmlub ntsej muag dajQhov cua thiab aeration tuaj yeem tiv thaiv hypoxia hauv zos hauv cov dej thiab tswj hwm cov kev ua ntawm cov kab mob ntawm cov kab mob uas tau ua tiav cov kab mob fileve. Nyob rau tib lub sijhawm, coagulants tuaj yeem ntxiv los pab sludge flocs agglomerate sai dua.

Sludge inactivation

 

Thaum muaj tshuaj tua kab mob ntau dhau los yog cov chaw muag tshuaj nyob hauv cov dej khib nyiab, cov sludge tuaj yeem poob nws cov haujlwm. Txhawm rau hais txog qhov no, lub tank regulating yuav tsum tau ntxiv rau cov ntu kev hloov pauv ntawm cov dej khib nyiab, tso cai rau nws kom raug kho tom qab nws cov kuab lom tau raug txo.

Thaum siv cov txheej txheem sludge hauv tsev kho mob rau tsev kho mob rov qab, thiab kev txhim kho cov kab mob rov qab, thiab ua kom pom kev nyab xeeb rau kev nyab xeeb thiab ua kom muaj txiaj ntsig zoo.Tiv Tauj Pebkom tau txais kev txhawb nqa kev tshaj lij.
