1. Sludge Bulking
Sludge bulking yog hais txog kev nthuav dav ntawm sludge ntim tshaj li ib txwm muaj. Cov ua tau muaj xws li microbial imbalance, qhia txog cov tshuaj lom neeg, kev cuam tshuam sab nraud, thiab cov yam ntxwv sludge. Cov kev daws teeb meem suav nrog kev kho cov dej muaj txiaj ntsig zoo, ua ntej kho cov tshuaj lom neeg, kho cov txheej txheem ua haujlwm, thiab tswj cov sludge rov qab.
2. Poob Sludge Settling
Cov sludge tsis zoo nyob hauv cov tso tsheb hlau luam aerobic tuaj yeem ua rau muaj cov khib nyiab ntxiv thiab turbidity. Ua rau muaj xws li kev nplawm ntau dhau, ntau dhau sludge concentration, thiab kev hloov pauv sai sai hauv cov khoom muaj zog. Cov kev daws teeb meem suav nrog kev kho qhov sib xyaw ua ke, tswj cov sludge concentration, ua kom cov dej muaj txiaj ntsig zoo, thiab kev tu lub sijhawm ntawm lub tank.
3. Cov ntxhiab tsw phem
Cov ntxhiab tsw tsis zoo, xws li hydrogen sulfide tsw, tuaj yeem tshwm sim hauv cov tso tsheb hlau luam aerobic. Qhov no feem ntau yog tshwm sim los ntawm oxygen deficiency lossis sludge acidification ua rau hydrogen sulfide ntau lawm. Cov kev daws teeb meem suav nrog nce aeration tus nqi, kho aerobic tank qhov cua, thiab tswj cov kua qaub.
4. Ntau dhau Algae loj hlob
Nyob rau hauv lub tank aerobic, ntau algae loj hlob tuaj yeem ua rau cov dej tig ntsuab, txo cov kev kho mob. Cov laj thawj yuav suav nrog kev siv lub teeb ntau dhau thiab qhov tsis sib xws hauv nitrogen-phosphorus piv. Cov kev daws teeb meem suav nrog kev tswj lub teeb ci, kho cov nitrogen-phosphorus piv, thiab ua kom muaj kev ntxhov siab hauv lub tank.
5. Qhov kub thiab txias hauv lub tank Aerobic
Qhov kub tsis txawv txav hauv lub tank aerobic tuaj yeem cuam tshuam rau kev ua haujlwm microbial thiab cov tshuaj tiv thaiv biochemical. Tej yam ua tau muaj xws li kev hloov pauv huab cua thiab kev hloov pauv hauv qhov kub thiab txias. Cov kev daws teeb meem suav nrog nce kev rwb thaiv tsev, kho qhov kub thiab txias, thiab txhim kho qhov cua.
6. Tshaj tawm hauv Aerobic Tank
Tshaj tawm hauv lub tank aerobic tuaj yeem yog vim muaj kev cuam tshuam ntau dhau lossis tsis muaj peev xwm kho tau.
