Qhov Tseem Ceeb Qhov txawv - Aerobic vs Anaerobic Wastewater Treatment
Kev kho dej khib nyiab kom raug yog qhov tseem ceeb los tiv thaiv cov kab mob hauv dej thiab tswj kom muaj kev noj qab haus huv rau cov kab mob. Ib txoj kev kho mob uas muaj cov kab mob microbes lossis cov kab mob muaj sia nyob yog lub npe hu ua kev kho dej khib nyiab lom neeg. Muaj ob hom kev kho dej khib nyiab xws li aerobic wastewater kho thiab anaerobic pov tseg dej kho. Kev kho cov dej khib nyiab aerobic yog ua los ntawm cov kab mob aerobic. Aerobic microorganisms xav tau oxygen; Yog li ntawd, oxygen yog muab rau aerobic wastewater kho tanks. Kev kho dej khib nyiab anaerobic yog ua los ntawm cov kab mob anaerobic. Yog li, anaerobic wastewater kho txheej txheem tshwm sim tsis muaj oxygen. Qhov sib txawv tseem ceeb ntawm kev kho cov dej khib nyiab aerobic thiab anaerobic yog tias hauv kev kho cov dej khib nyiab hauv aerobic, cov tso tsheb hlau luam tau muab cov pa oxygen tas li thaum, hauv kev kho dej khib nyiab anaerobic, gaseous oxygen yog tiv thaiv los ntawm kev nkag mus rau hauv lub cev.
Kev kho dej khib nyiab li cas?
txheej txheem kho dej khib nyiab tshwm sim los ntawm ob peb kauj ruam tseem ceeb xws li kev kho ua ntej, kev kho thawj zaug, kev kho mob thib ob lossis kev kho mob lom neeg, kev kho tertiary thiab kev zom zaub mov anaerobic. Kev kho cov dej khib nyiab lom neeg yog cov kauj ruam tseem ceeb hauv cov txheej txheem dej khib nyiab, thiab nws yog ua los ntawm cov kab mob xws li cov kab mob, nematodes, cov kab mob me me, thiab lwm yam. Cov organic teeb meem tam sim no hauv cov dej khib nyiab tau tawg los ntawm cov kab mob no. Kev kho mob lom neeg tuaj tom qab kev kho thawj zaug rau kev tshem tawm cov organic ntxiv hauv cov dej khib nyiab. Raws li tau hais los saum no, muaj ob hom kev kho mob lom neeg hu ua aerobic wastewater kho thiab anaerobic pov tseg dej kho.
Kev Kho Dej Aerobic yog dab tsi?
Aerobic wastewater kho txheej txheem yog tswj hwm los ntawm cov kab mob aerobic uas xav tau oxygen rau cov txheej txheem tawg. Aerobic wastewater kho tanks tas li muab cov pa oxygen. Nws yog ua los ntawm circulating cua los ntawm lub tso tsheb hlau luam. Rau kev ua haujlwm zoo ntawm cov kab mob aerobic, cov pa oxygen txaus yuav tsum muaj nyob rau hauv lub tank aerobic txhua lub sijhawm. Yog li ntawd, aeration yog tswj kom zoo thoob plaws hauv kev kho mob aerobic.
Muaj ob hom kev kho dej aerobic: txuas kab lis kev cai lossis cov yeeb yaj kiab ruaj khov thiab cov kab lis kev cai raug tshem tawm.
Daim duab 01: Txoj Kev Ua Haujlwm Sludge
Txoj kev coj noj coj ua
Hauv kab lis kev cai sib txuas, biomass yog cog rau ntawm cov khoom siv los yog xov xwm thiab cov dej khib nyiab tau dhau ntawm qhov chaw microbial. Trickling lim thiab rotating biological contactor yog ob kab ke kab ke.
Suspended Culture System
Hauv cov kab lis kev cai raug tshem tawm, biomass yog tov nrog dej khib nyiab. Ua kom cov sludge system thiab oxidation ditch yog ob qhov nrov tshem tawm kab lis kev cai.
Kev kho dej khib nyiab Anaerobic yog dab tsi?
Kev kho dej khib nyiab Anaerobic yog txheej txheem kev kho mob lom neeg uas muaj kab mob, tshwj xeeb tshaj yog cov kab mob, rhuav tshem cov organic hauv cov dej khib nyiab hauv qhov chaw tsis muaj oxygen. Anaerobic digestion yog ib tug paub zoo anaerobic wastewater kho txheej txheem. Lub degradation ntawm cov khoom siv organic yog ua anaerobically. Rau qhov zoo anaerobic digestion ntawm cov ntaub ntawv organic, qhov nkag ntawm huab cua mus rau hauv lub tank anaerobic yog tiv thaiv. Thaum lub sij hawm anaerobic digestion, methane thiab carbon dioxide raug tsim. Methane yog biogas. Li no, cov txheej txheem anaerobic digestion tuaj yeem siv los tsim cov roj biogas uas tuaj yeem siv los ua hluav taws xob.
Daim duab 02: Kev kho dej khib nyiab Anaerobic
Cov txheej txheem kho dej khib nyiab Anaerobic tshwm sim ntawm plaub kauj ruam tseem ceeb hu ua hydrolysis, acidogenesis, acetogenesis, thiab methanogenesis. Tag nrho cov kauj ruam no yog tswj hwm los ntawm cov kab mob anaerobic, tshwj xeeb tshaj yog cov kab mob thiab archaea.
Dab tsi zoo sib xws ntawm Aerobic thiab Anaerobic Wastewater Treatment?
- Aerobic thiab anaerobic wastewater kho cov txheej txheem yog cov txheej txheem dej khib nyiab lom neeg uas koom nrog cov kab mob nyob.
- Cov khoom siv organic complex tau tawg thaum lub sijhawm ob txheej txheem.
- Ob txheej txheem tsuas yog tswj hwm los ntawm cov kab mob.
Qhov txawv ntawm Aerobic thiab Anaerobic Wastewater Treatment yog dab tsi?
