Feem ntau hais lus, composting muab faib ua aerobic composting thiab anaerobic composting.Aerobic composting yog hais txog cov txheej txheem decomposition ntawm cov ntaub ntawv organic nyob rau hauv muaj oxygen, thiab nws cov metabolites feem ntau yog carbon dioxide, dej, thiab cua sov;Thaum anaerobic composting yog hais txog decomposition ntawm cov organic cov ntaub ntawv nyob rau hauv tsis muaj oxygen, thiab cov metabolites zaum kawg ntawm anaerobic decomposition yog Methane, carbon dioxide thiab ntau yam uas tsis muaj molecular hnyav intermediates xws li organic acids, thiab lwm yam. Traditional composting yog mas raws li anaerobic composting, Thaum niaj hnub composting feem ntau siv aerobic composting, vim hais tias aerobic composting yog yooj yim rau loj ntau lawm thiab tsis muaj feem xyuam rau ib puag ncig ib puag ncig.
Aeration thiab oxygen muab rau cov khoom siv raw khoom yog tus yuam sij rau kev vam meej ntawm composting.Tus nqi ntawm oxygen xav tau nyob rau hauv compost yog txuam nrog cov ntsiab lus ntawm cov organic teeb meem nyob rau hauv lub compost.Qhov ntau cov organic teeb meem, qhov ntau dua qhov kev siv oxygen.Feem ntau, cov pa oxygen xav tau hauv cov txheej txheem composting nyob ntawm tus nqi ntawm oxidized carbon.
Nyob rau hauv thaum ntxov theem ntawm composting, nws yog feem ntau decomposition kev ua ntawm aerobic microorganisms, uas yuav tsum tau zoo cua qhov chaw.Yog tias qhov cua tsis zoo, cov kab mob aerobic yuav raug cuam tshuam, thiab cov nplooj lwg yuav decomposed maj mam;Ntawm qhov tsis sib xws, yog tias qhov cua siab dhau lawm, tsis yog tsuas yog cov dej thiab cov as-ham hauv lub pob zeb yuav ploj mus, tab sis kuj tseem muaj cov organic teeb meem yuav decomposed, uas tsis zoo rau tsub zuj zuj ntawm humus.
Yog li ntawd, nyob rau theem pib, lub cev pawg yuav tsum tsis txhob nruj dhau, thiab lub tshuab tig tuaj yeem siv los tig lub cev pawg kom muaj cov pa oxygen ntawm pawg pawg.Lub sijhawm anaerobic lig yog qhov tsim nyog rau kev khaws cov khoom noj thiab txo qis volatilization poob.Yog li ntawd, lub compost yuav tsum tau muab compacted kom zoo los yog tsis tig.
Nws feem ntau ntseeg tias nws yog qhov tsim nyog los tswj cov pa oxygen hauv pawg ntawm 8% -18%.Hauv qab no 8% yuav ua rau anaerobic fermentation thiab tsim cov ntxhiab tsw phem;saum toj no 18%, lub pob yuav txias, ua rau muaj sia nyob ntawm cov kab mob pathogenic ntau.
Tus naj npawb ntawm kev hloov pauv yog nyob ntawm kev siv cov pa oxygen ntawm cov kab mob hauv cov kab noj hniav, thiab qhov zaus ntawm cov chiv ua kom muaj zog ntau dua nyob rau theem pib ntawm composting dua nyob rau theem tom ntej ntawm composting.Feem ntau, lub heap yuav tsum tig ib zaug txhua 3 hnub.Thaum qhov kub thiab txias tshaj 50 degrees, nws yuav tsum tau tig dua;Thaum qhov kub siab tshaj 70 degrees, nws yuav tsum tau qhib ib zaug txhua 2 hnub, thiab thaum kub siab tshaj 75 degrees, nws yuav tsum tau qhib ib zaug ib hnub kom txias sai.
Lub hom phiaj ntawm kev xa cov khib nyiab khib nyiab yog kom ferment tusyees, txhim kho qhov degree ntawm composting, ntxiv cov pa oxygen, thiab txo cov dej noo thiab kub, thiab nws raug nquahu kom tig lub vaj teb manure compost tsawg kawg 3 zaug.
