Biogas yog tsim los ntawm methane (50-70%), carbon dioxide (30-40%) thiab hydrogen sulphide. Txawm li cas los xij cov kab ntawm nitrogen, hydrogen thiab oxygen arc kuj pom.
Qhov twg yog tsim thaum kho dej phwj?
Methane, Hydrogen sulfide, Carbon dioxide, thiab Hydrogen: Cov pa roj no yog ib feem ntawm biogas tsim thaum lub sijhawm kho dej phwj tuaj.
Nyob rau theem twg ntawm kev kho dej phwj yog biogas tsim?
Kev zom cov dej phwj hauv nroog (MSS) tshwm sim hauv peb kauj ruam yooj yim: acidogen, methanogens, thiab methanogens. Thaum lub sij hawm 30-hnub digestion, 80-85% ntawm biogas yog tsim nyob rau hauv thawj 15-18 hnub.
Cov pa roj twg tso rau hauv kev kho dej phwj?
Cov pa roj carbon monoxide thiab cov pa roj carbon dioxide raug tso tawm los ntawm decomposition ntawm cov khoom siv organic. Methane yog tso tawm thaum tuav thiab kho cov dej khib nyiab hauv nroog los ntawm cov khoom siv anaerobic decomposition.
Cov roj methane nyob qhov twg thaum lub sijhawm kho cov dej khib nyiab?
Methane raug tso tawm thaum tuav thiab kho cov dej khib nyiab hauv nroog los ntawm cov anaerobic decomposition ntawm cov khoom organic. Cov teb chaws tsim kho feem ntau cia siab rau hauv nruab nrab aerobic wastewater kho tshuab los sau thiab kho cov dej khib nyiab hauv nroog.
