Anaerobic tso tsheb hlau luam yog ib feem tseem ceeb ntawm cov txheej txheem dej phwj. Lawv txoj haujlwm yog decompose muaj teeb meem rau hauv inorganic teeb meem los ntawm kev nqis tes ua ntawm cov microorganisms, yog li ua tiav lub hom phiaj ntawm lub hom phiaj ua kom zoo. Tsuas yog muab tso, txoj haujlwm ntawm cov tso tsheb hlau luam ntawm anaerobic yog kom decompose cov teeb meem hauv dej phwj hauv dej phwj.
Txoj haujlwm ntawm kev tso tsheb hlau roj anaerobic yog feem ntau los kho cov organic nyob hauv cov kab mob wastewater los ntawm cov kab mob anaerobic tsis muaj cov pa oxygen. Cov txheej txheem no suav nrog cov hydrolysis, acidification thiab methanation ntawm cov organic teeb meem hauv dej thiab txhim kho lub biodegradity ntawm cov dej phwj tuaj, uas yog qhov zoo rau kev kho aerobic. Hauv kev kho mob ntsigical roj ntsha, cov organic muaj teeb meem los ntawm cov txheej txheem insolub los ntawm cov soluble monomers lossis dimers, ib txheej txheem hu ua hydrolysis. Tom qab, cov molecular cov organic organic me me yog kev txiav txim siab ntxiv los ntawm cov kab mob allaubic me ntsis, thiab thaum kawg tsim tawm methane thiab carbon dioxide. Anaerobic tso tsheb hlau luam yog tsim nyog rau kev kho cov dej organic ntau vim tias lawv muaj cov yam ntxwv ntawm dav ntau, siab thauj khoom thiab qis sludge ntau lawm.
Yuav ua li cas Anaerobic tso tsheb hlau hlau ua tiav txoj haujlwm no? Muaj ib hom microorganism hu ua Anaerobic tso tsheb hlau luam, uas tuaj yeem decompose cov teeb meem hauv kev tsis muaj pa oxygen. Cov kab mob me no tuaj yeem siv cov organic teeb meem raws li lawv lub zog thiab tawg nws hauv cov khoom yooj yim. Cov txheej txheem no ua rau qee cov pa roj teeb meem, xws li methane thiab hydrogen sulfide, tab sis cov roj av no yuav raug tawg ntxiv lub hom phiaj ntawm lub hom phiaj ua kom zoo.
Tsis tas li ntawd, lub anaerobic tank muaj cov haujlwm hauv qab no:
1. Tshem tawm nitrogen thiab phosphorus los ntawm dej phwj. Hauv lub anaerobic tank, cov kab mob anaerobic tuaj yeem hloov nitrogen thiab phosphorus hauv cov ntawv nqus mus rau hauv cov foos uas yooj yim dua los ntawm lwm cov kab mob me me. Qhov no tuaj yeem txo cov kuab paug ntawm nitrogen thiab phosphorus rau ib puag ncig.
2. Txo cov tshuaj oxygen xav tau (COD). Cov microorganisms hauv cov hlau tso tsheb hlau luam tsis tuaj yeem kho cov teeb meem organic, yog li txo cov pa oxygen thov hauv dej phwj. Qhov no pab txhawm rau txhim kho kev txuag dej phwj.
3. Txo cov nyiaj ntawm sludge tsim tawm. Hauv lub anaerobic tank, cov kab mob me tuaj yeem tsoo cov teeb meem organic rau cov khoom ua kom yooj yim, yog li txo tus nqi ntawm sludge tsim tawm. Qhov no pab kom txo tus nqi ntawm kev kho kom tsawg.
