Cov dej noo yog ib qho tseem ceeb hauv cov txheej txheem compost fermentation.Lub luag haujlwm tseem ceeb ntawm dej hauv compost yog:
(1) Dissolve organic teeb meem thiab koom nrog cov metabolism hauv cov kab mob;
(2) Thaum cov dej evaporates, nws tshem tawm cov cua sov thiab ua lub luag haujlwm hauv kev tswj qhov kub ntawm cov compost.

Yog li cov lus nug yog, dab tsi yog qhov dej noo zoo rau compost?

Cia peb xub saib ntawm daim duab hauv qab no.Los ntawm daim duab, peb tuaj yeem pom tias kev loj hlob ntawm cov kab mob thiab qhov yuav tsum tau muaj cov pa oxygen ob qho tib si ncav cuag lawv lub ncov thaum cov dej noo yog 50% mus rau 60% vim tias cov kab mob aerobic yog cov nquag nquag nyob rau lub sijhawm no.Yog li, thaum composting nrog cov pov tseg hauv tsev, nws yog qhov zoo tshaj plaws los siv cov dej noo ntawm 50% mus rau 60% (los ntawm qhov hnyav).Thaum muaj dej noo ntau dhau, xws li ntau dua 70%, huab cua yuav raug nyem tawm ntawm qhov sib txawv ntawm cov khoom siv raw, txo cov porosity dawb thiab cuam tshuam rau huab cua diffusion, uas yuav yooj yim ua rau lub xeev anaerobic thiab yuav ua rau muaj teeb meem hauv kev kho mob. ntawm leachate, ua rau aerobic microorganisms.Tsis muaj kev yug me nyuam thiab cov kab mob anaerobic muaj zog dua;thiab thaum cov dej noo tsawg dua 40%, qhov kev ua ntawm microbial txo qis, cov organic teeb meem tsis tuaj yeem decomposed, thiab composting kub txo, uas nyob rau hauv lem ua rau ib tug ntxiv txo nyob rau hauv lom kev ua si.

 Kev sib raug zoo ntawm cov ntsiab lus noo noo thiab oxygen xav tau thiab kev loj hlob ntawm cov kab mob

Feem ntau, cov dej noo ntawm cov khib nyiab hauv tsev yog qis dua qhov zoo tshaj plaws, uas tuaj yeem hloov kho los ntawm kev ntxiv cov dej phwj tuaj, sludge, tib neeg thiab tsiaj tso zis, thiab quav.Qhov hnyav piv ntawm qhov ntxiv txias rau cov khib nyiab tuaj yeem suav tau raws li cov qauv hauv qab no:

Nyob rau hauv cov mis, M - qhov hnyav (ntub hnyav) piv ntawm cov regulator rau cov khib nyiab;
Wm, Wc, Wb — raws li cov dej noo ntawm cov khoom sib xyaw, khib nyiab, thiab txias.
Yog tias cov dej noo ntawm cov khib nyiab hauv tsev siab dhau lawm, yuav tsum tau siv cov kev kho kom zoo, suav nrog:
(1) Yog tias thaj chaw thaj av thiab lub sijhawm tso cai, cov khoom tuaj yeem nthuav tawm rau kev nplawm, uas yog, evaporation ntawm cov dej tuaj yeem txhawb nqa los ntawm tig pawg;
(2) Ntxiv cov khoom xoob lossis nqus dej rau cov khoom siv, feem ntau yog siv: straw, chaff, nplooj qhuav, sawdust thiab compost khoom, thiab lwm yam., los pab hauv absorbing dej thiab nce nws cov void ntim.
Muaj ntau txoj hauv kev los txiav txim siab cov dej noo.Cov txheej txheem ib txwm yog ntsuas qhov poob ntawm cov khoom ntawm qhov ntsuas kub ntawm 105 ± 5 ° C thiab lub sijhawm nyob ntawm 2 mus rau 6 teev.Txoj kev ntsuas ceev kuj tseem siv tau, uas yog, cov ntsiab lus noo noo ntawm cov khoom yog txiav txim siab los ntawm kev ziab cov khoom hauv lub qhov cub microwave rau 15-20 min.Nws kuj tseem tuaj yeem txiav txim siab seb cov dej noo puas tsim nyog raws li qee qhov tshwm sim ntawm cov khoom siv composting: yog tias cov khoom muaj dej ntau dhau, nyob rau hauv cov ntaub ntawv ntawm qhib-cua composting, leachate yuav raug tsim;Thaum lub sij hawm dynamic composting, agglomeration los yog agglomeration yuav tshwm sim, thiab txawm tsw yuav tsim.

Hais txog kev tswj cov dej noo thiab kev hloov ntawm cov khoom siv compost, cov hauv qab no tseem yuav tsum tau ua raws li:

① Tsim nyog qis hauv cheeb tsam yav qab teb thiab siab dua nyob rau sab qaum teb
② Tsim nyog qis dua thaum lub caij los nag thiab siab dua nyob rau lub caij qhuav
③ Tsim nyog qis rau lub caij kub tsis tshua muaj kub thiab siab dua nyob rau lub caij kub kub
④ Lub hnub nyoog clinker yog qhov tsim nyog qis, thiab cov khoom xyaw tshiab yog tsim nyog
⑤ Kho qhov qis C / N kom tsim nyog thiab kho siab C / N kom tsim nyog
