Qhov sib txawv tseem ceeb ntawm cov activated sludge thiab thawj cov sludge yog cov activated sludge muaj cov ntsiab lus siab ntawm cov kab mob, whereas thawj sludge tsis muaj cov kab mob.
Sludge thiab slurry tuaj yeem txhais tau tias yog qhov tshwm sim ntawm cov txheej txheem kev lag luam. Lawv txawv ntawm lawv qhov kev ntxhib los mos vim lawv cov khoom. Txawm li cas los xij, sludge thiab slurries tuaj yeem ua los ntawm cov txheej txheem zoo sib xws. Lo lus activated sludge yog hais txog cov txheej txheem uas muaj cov kab mob siab, nrog rau cov kab mob, protozoa, thiab fungi, uas tshwm sim raws li xoob, clumped loj ntawm cov khoom zoo. Thawj sludge yog ib hom sludge tsim los ntawm cov tshuaj los nag lossis daus, sedimentation, thiab lwm yam txheej txheem tseem ceeb.
Dab tsi yog Activated Sludge?
Lub sij hawm qhib cov sludge hais txog cov txheej txheem uas muaj cov kab mob siab, nrog rau cov kab mob, protozoa, thiab fungi, raws li xoob clumped loj ntawm cov khoom zoo. Cov sludge no khaws cia rau hauv kev ncua los ntawm kev nplawm, uas yog pab tshem tawm cov organic teeb meem ntawm cov dej khib nyiab.
Cov txheej txheem qhib cov sludge tuaj yeem piav qhia raws li hom kev kho dej khib nyiab siv rau kev kho cov dej phwj tuaj lossis cov dej khib nyiab. Cov txheej txheem no suav nrog kev ua kom aeration thiab cov khoom siv roj ntsha uas muaj cov kab mob thiab protozoa.
Daim duab 01: Ib qho Kev Ua Txhaum Sludge Tank
Cov khoom hauv cov sludge qhib muaj xws li lub tank aeration thiab lub tank tso dej. Lub aeration tank yog qhov twg huab cua los yog oxygen yog txhaj rau hauv cov cawv sib xyaw. Lub chaw tso dej yog qhov chaw lom neeg flocs nyob; Yog li ntawd, kev sib cais ntawm cov roj ntsha sludge los ntawm cov dej ntshiab uas kho tau tshwm sim ntawm lub tank no. Lub tank settling tseem hu ua qhov kawg clarifier lossis lub tank thib ob. Cov flocs lom uas tsim nyob rau hauv lub tank no hu ua sludge pam.
Feem ntau, hauv cov chaw kho dej phwj tuaj, cov sludge qhib tau yog cov txheej txheem lom neeg uas muaj ib lossis ob peb kauj ruam hauv qab no:
- Oxidizing carbonaceous biological teeb meem
- Oxidizing nitrogenous teeb meem xws li ammonium thiab nitrogen hauv cov teeb meem lom neeg
- Tshem tawm cov khoom noj
Primary Sludge yog dab tsi?
Primary sludge yog ib hom sludge tsim los ntawm cov tshuaj los nag, sedimentation, thiab lwm yam txheej txheem tseem ceeb. Nws tsuas yog muaj cov organic teeb meem xws li quav, zaub, txiv hmab txiv ntoo, textiles, ntawv, thiab lwm yam. Nws yog cov sludge zoo ib yam uas tshwm sim raws li cov kua dej tuab nrog cov dej ntawm ib ncig ntawm 93% thiab 97%.
Daim duab 02: Lub Ncauj Sludge Qhuav txaj
Tsis zoo li cov sludge activated, thawj sludge tsis xav tau aeration, thiab ntau decomposition tshwm sim thaum lub sij hawm tsim ntawm thawj sludge. Thawj sludge cov ntaub ntawv thaum lub sij hawm thawj cov dej phwj kho, thiab nws tsis muaj flocs ntawm decomposer microbes. Nws tshwm sim raws li ib tug concentrated suspension ntawm hais nyob rau hauv dej. Lub hom phiaj tseem ceeb ntawm cov kauj ruam no yog kev sib cais ntawm cov yooj yim tshem tawm cov khib nyiab thiab cov teeb meem lom neeg.
Dab tsi yog qhov txawv ntawm Kev Ua Txhaum Sludge thiab Thawj Sludge?
Sludge thiab slurry yog qhov tshwm sim ntawm cov txheej txheem kev lag luam. Lawv txawv ntawm lawv qhov kev ntxhib los mos vim lawv cov khoom. Qhov sib txawv tseem ceeb ntawm cov activated sludge thiab thawj cov sludge yog cov activated sludge muaj cov ntsiab lus siab ntawm cov kab mob, thaum thawj cov sludge tsis muaj cov kab mob.
Cov hauv qab no nthuav tawm qhov sib txawv ntawm cov sludge qhib thiab thawj cov sludge hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – Activated Sludge vs Primary Sludge
Lub sij hawm qhib cov sludge yog hais txog cov txheej txheem uas muaj cov kab mob siab, nrog rau cov kab mob, protozoa, thiab fungi, uas tam sim no yog xoob, clumped loj ntawm cov khoom zoo. Thawj sludge yog ib hom sludge tsim los ntawm cov tshuaj los nag lossis daus, sedimentation, thiab lwm yam txheej txheem tseem ceeb. Qhov sib txawv tseem ceeb ntawm cov activated sludge thiab thawj cov sludge yog cov activated sludge muaj cov ntsiab lus siab ntawm cov kab mob, thaum thawj cov sludge tsis muaj cov kab mob.
