upflow anaerobic sludge embhedeni ophendula (UASB)
I-UASB ingenye yezingqimba ezikhula ngesivinini esikhulu, esibonakala ngokugeleza kwendle okuphansi kuya phezulu embhedeni wendwangu eyimbudumbudu eyandisiwe. I-digester ihlukaniswe izingxenye ezintathu, okungukuthi umbhede wamadaka, ungqimba lwedaka nesihlukanisi sesigaba ezintathu. Isihlukanisi sihlukanisa igesi futhi sivimbele okuqinile ukuthi kungantanta futhi kuphume, ukuze i-MRT inyuke kakhulu uma iqhathaniswa ne-HRT, futhi ukusebenza kahle kokukhiqizwa kwemethane kuthuthukiswe kakhulu. Indawo yombhede we-sludge ibala kuphela i-30% yevolumu yokugaya ngokwesilinganiso, kepha ama-80 ~ 90% wento ephilayo yehlisiwe lapha.
Isihlukanisi sezigaba ezintathu yisisetshenziswa esiyisihluthulelo se-UASB anaerobic digester. Imisebenzi yayo eyinhloko ukwahlukaniswa kwegesi-ketshezi, ukwahlukaniswa okuqinile oketshezi kanye ne-sludge reflux, kepha konke kuqukethe uphawu lwegesi, indawo yokudonswa komhlaba kanye nokuhlanganiswa kwe-reflux.
Inqubo yenzuzo
① I-digester inesakhiwo esilula futhi akukho divayisi yokuxuba nokugcwalisa (ngaphandle kwesihlukanisi sesigaba ezintathu).
SR I-SRT ende ne-MRT ziyenza ifinyelele izinga eliphezulu lomthwalo.
Formation Ukwakheka kodaka oluyimbudumbudu kwenza ukuthi i-microorganism ingasebenzi kahle ngokwemvelo futhi inyuse uzinzo lwenqubo.
Okuqukethwe kwe-SS kokungcola kuphansi.
Inqubo amaphutha
①. kuzofakwa isihlukanisi sesigaba ezintathu.
② Umhambisi wamanzi osebenzayo uyadingeka ukwenza okuphakelayo kusatshalaliswe ngokulinganayo.
Okuqukethwe kwe-SS kufanele kube phansi.
④ Lapho umthwalo wokubacindezela usuphakeme noma umthwalo we-SS uphezulu, kulula ukulahlekelwa okuqinile kanye nezilwanyana ezincane.
Requirements Izidingo zobuchwepheshe eziphezulu zokusebenza.
