Qhov txawv ntawm MLSS thiab MLVSS yog tias MLSS ntsuas tag nrho cov khoom hnyav ntawm cov qauv muab, whereas MLVSS ntsuas tag nrho cov volatile feem ntawm tag nrho cov khib nyiab hauv cov qauv muab.
Lub sij hawm MLSS sawv cev rau Mixed Liquor Suspended Solids, thaum lub sij hawm MLVSS sawv cev rau Mixed Liquor Volatile Suspended Solids. Cov ntsiab lus no yog qhov tseem ceeb hauv kev tshuaj ntsuam chemistry, feem ntau hauv cov chaw kho dej khib nyiab, los ntsuas cov txheej txheem kho mob los ntawm kev txheeb xyuas tag nrho cov ntsiab lus hauv cov tso tsheb hlau luam.
MLSS (Mixed Liquor Suspended Solids) yog dab tsi?
Lo lus MLSS sawv cev rau Mixed Liquor Suspended Solids. Nws yog qhov concentration ntawm tshem tawm cov khib nyiab hauv lub tank aeration (thaum lub sij hawm ua kom cov sludge tsim) hauv kev kho dej khib nyiab. Feem ntau, qhov ntsuas no yog ntsuas los ntawm chav tsev milligrams ib liter (mg / L). Txawm li cas los xij, peb tuaj yeem ntsuas activated sludge feem ntau hauv grams ib liter (g / L). Qhov no yog sib npaug rau kilograms ib cubic meter. Cov cawv sib xyaw no tuaj yeem piav qhia raws li kev sib xyaw ua ke ntawm cov dej khib nyiab los yog cov dej tsis huv los yog cov dej khib nyiab ua ntej thiab cov activated sludge nyob rau hauv lub aeration tank.
MLSS feem ntau muaj cov kab mob thiab cov uas tsis yog biodegradable tshem tawm. Nws yog ib qho tseem ceeb ntawm cov txheej txheem activated sludge vim nws ua kom muaj qhov txaus ntawm cov khoom siv biomass rau cov khoom siv ntawm cov kuab tshuaj organic kom noj txhua lub sijhawm. Peb hu nws cov khoom noj rau microorganism piv lossis F / M piv.
Nws yog ib qho tseem ceeb kom tswj tau qhov piv txwv no kom tau txais kev noj zaub mov ntau dua los ntawm biomass. Qhov no, nyob rau hauv lem, minimizes qhov poob ntawm residual zaub mov nyob rau hauv lub effluent. Tsis tas li ntawd, qhov kev siv biomass ntau dua, qhov kev xav tau ntawm biochemical oxygen (BOD) qis dua.
MLVSS (Mixed Liquor Volatile Suspended Solids) yog dab tsi?
Lo lus MLVSS sawv cev rau Mixed Liquor Volatile Suspended Solids. Feem ntau, peb tuaj yeem piav qhia nws raws li kev tshem tawm microbiological nyob rau hauv lub aeration tank ntawm lub tshuab ua haujlwm-sludge cov dej khib nyiab khib nyiab. Peb tuaj yeem siv qhov ntsuas mg / L los ntsuas qhov ntsuas no hauv cov cawv sib xyaw ntawm lub tank aeration.
Feem ntau, cov khoom khib nyiab biomass hauv cov dej khib nyiab pov tseg tau qhia tias yog tag nrho cov khib nyiab tshem tawm lossis TSS thiab cov khoom tawg yooj yim tshem tawm lossis VSS. Kev sib xyaw ua ke ntawm cov sludge rov ua dua nrog cov dej khib nyiab zoo hauv bioreactor muab cov cawv sib xyaw ua kom tsis muaj zog tshem tawm cov khib nyiab. Cov khib nyiab no muaj biomass, tsis-degradable volatile suspended solids, thiab inert inorganic tag nrho suspended solids.
Qhov txawv ntawm MLSS thiab MLVSS yog dab tsi?
MLSS thiab MLVSS yog cov ntsiab lus tseem ceeb hauv kev tshuaj ntsuam chemistry txog cov nroj tsuag dej khib nyiab. Lawv pab ntsuam xyuas cov txheej txheem kho mob los ntawm kev txheeb xyuas tag nrho cov ntsiab lus hauv cov tso tsheb hlau luam. MLSS stands rau Mixed Liquor Suspended Solids, whereas MLVSS stands for Mixed Liquor Volatile Suspended Solids. Qhov sib txawv tseem ceeb ntawm MLSS thiab MLVSS yog tias MLSS ntsuas tag nrho cov khoom hnyav ntawm cov qauv muab, whereas MLVSS ntsuas tag nrho cov volatile feem ntawm tag nrho cov khib nyiab hauv cov qauv muab. Ntxiv mus, cov khoom nyob rau hauv MLSS muaj cov kab mob thiab cov uas tsis yog biodegradable suspended teeb meem, thaum MLVSS muaj biomass, tsis-degradable volatile suspended solids, thiab inert inorganic khoom.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm MLSS thiab MLVSS hauv daim ntawv teev npe rau kev sib piv ntawm ib sab.
Summary – MLSS vs MLVSS
Lub sij hawm MLSS sawv cev rau Mixed Liquor Suspended Solids, thaum lub sij hawm MLVSS sawv cev rau Mixed Liquor Volatile Suspended Solids. Qhov sib txawv tseem ceeb ntawm MLSS thiab MLVSS yog tias MLSS ntsuas tag nrho cov khoom hnyav ntawm cov qauv muab, whereas MLVSS ntsuas tag nrho cov volatile feem ntawm tag nrho cov khib nyiab hauv cov qauv muab.
