1. Oxygen mov los ntawm kev xa cov pawg yog ib qho ntawm cov kev mob tshwm sim rau kev tsim aerobic fermentation.Lub luag haujlwm tseem ceeb ntawm kev xa rov qab:
① Muab cov pa oxygen kom ceev cov txheej txheem fermentation ntawm cov kab mob;② Kho qhov kub thiab txias;③ Qhuav pawg.
Yog hais tias tus naj npawb ntawm tig me me, qhov cua ntim tsis txaus los muab cov pa oxygen txaus rau cov kab mob, uas yuav cuam tshuam rau qhov nce ntawm fermentation kub;Yog hais tias tus naj npawb ntawm turnings siab dhau lawm, cov cua sov ntawm cov khib nyiab khib nyiab yuav poob, uas yuav cuam tshuam rau qib ntawm kev puas tsuaj ntawm fermentation.Feem ntau raws li qhov xwm txheej, pawg yog muab 2-3 zaug thaum lub sij hawm fermentation.
2. Cov ntsiab lus ntawm cov organic teeb meem cuam tshuam rau qhov chaw khaws khoom kub thiab qhov cua thiab cov pa oxygen.
Cov ntsiab lus ntawm cov organic teeb meem tsawg dhau lawm, cov cua sov uas tsim los ntawm decomposition tsis txaus los txhawb thiab tswj kev loj hlob ntawm cov kab mob thermophilic nyob rau hauv lub fermentation, thiab nws yog ib qho nyuaj rau lub compost heap mus txog rau lub high kub theem, uas cuam tshuam rau kev tu cev thiab harmless nyhuv ntawm fermentation.Tsis tas li ntawd, vim muaj cov ntsiab lus ntawm cov organic teeb meem tsawg, nws yuav cuam tshuam rau kev ua haujlwm ntawm cov chiv thiab siv tus nqi ntawm cov khoom fermented.Yog hais tias cov ntsiab lus ntawm cov organic teeb meem siab dhau lawm, yuav tsum muaj cov pa oxygen ntau, uas yuav ua rau muaj kev cuam tshuam los ntawm kev xa cov pa oxygen, thiab tej zaum yuav ua rau muaj kev mob anaerobic vim muaj cov pa oxygen tsis txaus.Qhov tsim nyog cov ntsiab lus organic yog 20-80%.
3. Qhov zoo tshaj plaws C / N piv yog 25: 1.
Hauv fermentation, organic C feem ntau yog siv los ua lub zog rau cov kab mob.Feem ntau ntawm cov organic C yog oxidized thiab decomposed rau hauv CO2 thiab volatilized thaum lub sij hawm microbial metabolism, thiab ib feem ntawm C yog lub cell teeb meem ntawm microorganisms lawv tus kheej.Nitrogen feem ntau yog siv rau hauv kev sib txuas ntawm protoplasts, thiab qhov zoo tshaj plaws C / N piv yog 4-30 nyob rau hauv cov nqe lus ntawm kev noj haus ntawm cov kab mob.Thaum C / N piv ntawm cov organic teeb meem nyob ib ncig ntawm 10, cov organic teeb meem yog decomposed los ntawm cov kab mob ntawm tus nqi siab tshaj.
Nrog rau qhov nce ntawm C / N piv, lub sij hawm fermentation tau ntev heev.Thaum C / N piv ntawm cov khoom siv raw yog 20, 30-50, 78, lub sij hawm fermentation sib xws yog li 9-12 hnub, 10-19 hnub, thiab 21 hnub, tab sis thaum C / N piv yog ntau dua 80. Thaum : 1, fermentation tsuas yog nyuaj rau ua.
C / N piv ntawm txhua fermentation raw khoom yog feem ntau: sawdust 300-1000, straw 70-100, raw khoom 50-80, tib neeg quav 6-10, nyuj quav 8-26, npua quav 7-15, qaib quav 5 -10, Dej phwj tuaj 8-15.
Tom qab composting, C / N piv yuav txo qis dua li ua ntej composting, feem ntau 10-20: 1.Qhov no hom C / N piv ntawm decomposing thiab fermenting muaj zoo fertilizer efficiency nyob rau hauv kev ua liaj ua teb.
4. Txawm hais tias cov dej noo haum ncaj qha cuam tshuam rau fermentation ceev thiab qib ntawm decomposing.
Rau sludge fermentation, qhov tsim nyog noo noo ntawm pawg yog 55-65%.Hauv kev ua haujlwm tiag tiag, txoj kev yooj yim ntawm kev txiav txim siab yog raws li hauv qab no: tuav cov khoom kom nruj nrog koj txhais tes los ua ib lub pob, thiab yuav muaj cov cim dej, tab sis nws yog qhov zoo dua uas cov dej tsis ntws tawm.Qhov zoo tshaj noo noo rau raw khoom fermentation yog 55%.
5. Granularity
Cov pa oxygen xav tau rau fermentation yog nkag los ntawm qhov pores ntawm fermentation raw khoom hais.Qhov porosity thiab pore loj nyob ntawm seb qhov luaj li cas thiab lub zog ntawm cov qauv.Zoo li daim ntawv, tsiaj txhu thiab nroj tsuag, thiab cov ntaub fiber ntau, qhov ntom ntom yuav nce ntxiv thaum raug dej thiab siab, thiab cov pores ntawm cov khoom yuav raug txo kom tsawg, uas tsis tsim nyog rau qhov cua thiab cov pa oxygen.Qhov loj me me yog feem ntau 12-60mm.
6. Cov kab mob pH tuaj yeem tsim muaj ntau dua pH, thiab qhov tsim nyog pH yog 6-8.5.Feem ntau tsis tas yuav kho pH thaum fermentation.
