Anaerobic Wastewater Kev Kho Mob: Txheej Txheem, Theem & Txheej Txheem Tsim Qauv Piav Qhia
Dab tsi yog Anaerobic dej khib nyiab khib nyiab?
Anaerobic dej khib nyiab siv cov pa oxygen-avers polyges kom tawg cov kuab paug orgeic tsis xav tau. Lub zog hluav taws xob no tshwm sim hauv cov txheej txheem biological uas tswj hwm nruj oxygen-dawb tej yam kev mob, ua rau nws zoo rau lub siab-zog muaj kev muaj zog muaj effluents.
CORS TSHUAB: Ob-theem biodegradation
Acidogenesis phase (acid tsim)
Anaerobic acidogenic bacteria hydrolyze complex organic teeb meem (cov rog, cov protein, carbohdrates)
Hloov kho cov pa phem rau hauv cov accel clatile fattty acids (vfas) xws li acetic, propionic, thiab butyric acid
Methanogenesis phase (roj ntau lawm)
Acetogenesis: TSHWJ XEEB MroFOBES Transformes Transforma mus rau Acetate, Hydrogen (H₂), thiab carbon dioxide (Coos)
Methane synthesis: Methanogenic Archaea haus acetate thiab h₂ \/ co \/ co \/ {{{{{% ntawm biogas - thiab tseem tshuav
Byproduct Qhab Valorization & Tawm
Biogas sau: CH₄-Rich-Rich Roj ({500-700 btu \/ ft³) yog ntes rau onsite hluav taws xob tiam (cua sov \/ hluav taws xob)
Kho effluent: Txo cov lej \/ lub cev ({{{{{{{{}} kev tshem tawm) dej ntws mus rau theem nrab kev kho mob lossis kev tawm tsam kev nyab xeeb
Cov Khoom Noj Khoom Haus Biosolids Muaj Nyiaj: Digestate Broproduc ua haujlwm ua cov chiv ua liaj ua teb tom qab stirilization
Lub kaw lus teeb tsa rau cov kev lag luam xav tau
- Ib Leeg Nyob Systems: Acidogenises + Acidanogenesis hauv ib reactor - raug nqi rau kev tsav tsheb khiav tawm hauv lub zog
- Ntau hom kab nruab: Cais cov roj av luam yeeb & tshuaj tua neeg me - kev ua kom zoo rau PH \/ TSO RAU KUB KUB
- Hybrid Designs: Sib txuas ulb (upflow anaerobic sludge pam) lossis egsb (nthuav dav granular sludge txaj) reactors nrog kev kho tom qab
Qhov tseem ceeb Daim Ntawv Thov & Cov Nyiaj Pab
- Cov txheej txheem pov tseg nrog 1,500-50, {3}} mg \/ l cod \/ l cod (Khoom noj khoom haus, khoom noj, tshuaj lom neeg)
- 40% kev ua haujlwm qis dua vs aerobic tshuab vim tias muaj xoom xav tau
- 85% me me sludge ntau lawm txo cov nuj nqis pov tseg
- Enables Zog-cov chaw zoo ntawm Biogas Cogenation
