Cov txheej txheem tseem ceeb
1. Kev Kho Mob Ua Ntej
Bar Screen: Siv los tshem cov khoom loj loj los ntawm cov dej khib nyiab.
Sand Cedling Tank: Tshem tawm cov pa hluav taws hnyav xws li cov xuab zeb hais los ntawm cov dej ntas.
Roj sib cais tank: tshem tawm cov impurities xws li roj thiab plaub ntawm wastewater. Ib qho khoom siv raj nyob rau hauv cov roj sib cais tank kom nce qhov deb ntawm cov roj carplets nce, thiab cais ntau cov roj.
Cov pas dej uas tswj kav: Kev tswj cov dej muaj nuj nqis thiab ntsuas cov kev cuam tshuam rau cov dej kom muaj nuj nqis thiab zoo ntawm cov kev kho tom ntej. Hauv qab ntawm lub tank regulating yog nruab nrog cov txiv ntseej perforated, uas ua kom sib xyaw ntawm cov sib txawv thiab lub sijhawm tusyees hauv lub tank los ntawm kev ua kom muaj cua. Nyob rau tib lub sijhawm, nws kuj muaj cov haujlwm ntawm cov hydrolysis thiab acidposing loj loj organic molecules thiab txhim kho lub biodegradity ntawm wantewater.
Cua flocation thiab flocculation: coagulants ntxiv rau huab cua floitation tshuab, thiab cov tshuaj sib tov ntws mus rau saum huab cua flotation ntaus ntawv tom qab flocculation. Zoo supersaturated gas sib xyaw nrog cov khib nyiab hauv dej los ua cov dej qab los ntawm cov dej. Tus scraper tsis tu ncua scrapes tawm ntawm lub qab poob, thiab lub raj nplaim ntab rau hauv sludge concentration tank rau kev kho hluav taws xob los ntawm cov raj xa dej.
2. Biochemical Kev Kho Mob
Kev Kho Mob Anaerobic:
Siv anaerobic tshuab lossis hydrolytic acidification kom decompose cov teeb meem organic. Thaum lub sijhawm cov txheej txheem no, cov molecic loj molecules tuaj yeem decomposed rau hauv cov txheej txheem organic me me rau kev tshem tawm ntxiv hauv cov txheej txheem aerobic.
Kev sib piv ntawm ob lub anaerobic cov txheej txheem xaiv:
Qhov kom zoo ntawm Anaerobic cov txheej txheem yog tias nws tuaj yeem kho tau yooj yim los xij, tshwj xeeb yog nws tsis tuaj yeem kho tau cov khoom siv ignicidater lossis cov khoom siv tau muaj zog, uas yuav cuam tshuam cov nyhuv kho mob.
Cov txiaj ntsig zoo: Tsim kom kho cov dej khib nyiab uas muaj cov protein ntau xws li cov protein ntau xws li cov muaj protein, cov rog, thiab lwm yam.
Qhov tsis zoo: Lub sijhawm hydrolysis ntev ntev yuav tsum tau thaum ua. Cov dej ua haujlwm zoo rau cov neeg lim dej siab, thiab yuav tsum tsis txhob muaj cov khib nyiab ntau dhau hauv cov dej khib nyiab.
Cov txheej txheem siv tau yog ib qho kev kho mob anaerobic haum rau kev kho mob organic wastewater, tshwj xeeb tshaj yog thaum lub taub dej muaj cov cim siab thiab lub cev siab. Lub UASB reactor tswj cov dej ntws nce los los txhawb cov organic teeb meem hauv qab no thiab yog degraded los ntawm cov kab mob hauv ib puag ncig ntawm anaerobic. Lub60B reactor muaj cov khoom siv zoo ua kua muaj peev xwm cais muaj peev xwm thiab yog qhov tsim nyog rau kev kho dej khib nyiab nrog cov khoom siv dej nyuaj.
Cov txiaj ntsig: Cov nyhuv yog qhov tseem ceeb rau cov dej khib nyiab uas muaj cov teeb meem organic ntau, tshwj xeeb tshaj yog rau cov neeg khib nyiab nrog cov haujlwm siab. Muaj zog hloov kho kom ua haujlwm, muaj peev xwm hloov kho rau cov xwm txheej uas muaj pes tsawg leeg ntawm Wastewater hloov ntau. Tus reactor muaj cov qauv yooj yim thiab yog yooj yim rau kev khiav lag luam thiab tswj hwm.
Qhov tsis zoo: Nws yog nkag siab rau cov ntsiab lus ntawm cov khib nyiab hauv dej hauv dej thiab yuav tsum muaj cov khoom siv ua kua ua kom zoo sib cais. Nws yog nkag siab txog kev hloov pauv ntawm cov khoom tsis zoo thiab yuav tsum tau ua haujlwm zoo thiab tswj.
Kev Kho Mob Aerobic:
Kev txais yuav cov tshuab ua haujlwm sludge thev naus laus zis lossis kev sib chwv roj ntsha ua haujlwm oxiologation oxidation thiab phosphorus tshem tawm cov teeb meem ntxiv rau cov biphດ. Los ntawm oxidizing cov teeb meem orgidizing kom muaj zog thiab hloov nws mus rau hauv cov tshuaj tsis muaj kev phom sij xws li cov pa roj carbon dioxide thiab dej.
3. Kev Kho Mob
Chlorine Dioxide thiab Sodium Chlope Kev Tiv Thaiv:
Ua kom muaj kev nyab xeeb ntawm cov dej ua haujlwm effluent zoo. Lub sijhawm sib cuag sib cuag yuav tsum tsis pub tsawg tshaj 30 feeb, thiab cov kev xav tau zoo yuav tsum tsis pub tsawg tshaj 50mg / l.
Ozone tshuaj tua kab:
Ozone muaj cov tshuaj oxidizing muaj zog thiab tuaj yeem tua cov kab mob thiab cov noob kab mob, tshem cov pa paug, tsw, thiab phoborine los ntawm cov dej khib nyiab. Nws tseem tuaj yeem txiav txim siab txog kev kho siab heev.
4. Sib sib zog nqus (yog tias yuav tsum tau):
Txais kev sib xyaw ua ke ntawm roj ntsha thiab cov kws kho lub cev, xws li siv cov roj ntsha roj carbon monologble tau siv cov tshuaj ntsuab, thiab lwm yam) thiab lwm yam) thiab lwm yam) thiab lwm yam) thiab lwm yam.
