Compostingyog ib txoj kev uas degrades thiab stabilizes cov organic pov tseg los ntawm kev ua ntawm cov kab mob kom tsim tau cov khoom tsim nyog rau kev siv av.
Covtxheej txheem fermentationkuj yog lwm lub npe rau composting.Organic pov tseg yuav tsum tsis tu ncua zom, stabilized, thiab hloov mus rau hauv cov organic chiv los ntawm kev ua ntawm cov kab mob nyob rau hauv cov xwm txheej ntawm cov dej txaus, carbon-nitrogen ratio, thiab oxygen concentration.Tom qab cov txheej txheem fermentation ntawm composting zoo, cov khoom pov tseg cov organic yog qhov ruaj khov, cov ntxhiab tsw ploj mus, thiab nws qhov tseem ceeb tsis muaj cov kab mob phom sij thiab cov noob nroj tsuag.Nws tuaj yeem siv los ua cov av txhim kho thiab cov organic chiv hauv av.
Yog li ntawd, tsim thiab tswj ib puag ncig zoo rau kev loj hlob microbial yog ib qho tseem ceeb rau kev ua kom cov compost zoo.Lub luag haujlwm tseem ceeb kom ua tiav lub hom phiaj no yog kev ua tiav thaum ntxov ntawm cov khoom siv organic.Cov kauj ruam hauv qab no yog koom nrog hauv Kev Ua Haujlwm Pib ntawm cov khoom siv compost raw:
1. Kev tshuaj xyuas cov khoom siv raw: impurities thiab cov khoom tsis huv uas tsis yog compostable raug tshem tawm ntawm cov khoom siv raw.Piv txwv li, hlau, pob zeb, iav, yas, thiab lwm yam.
2. Crushing: Tej yam khoom loj loj uas nyuaj rau kev tawg, xws li cov khoom noj khoom haus, cov nroj tsuag, cardboard, agglomerated sludge, thiab tib neeg pov tseg, yuav tsum tau crushed.Pulverization yog siv los txhim kho thaj tsam ntawm cov khoom siv raw, txhawb cov microbial decomposition, thiab txhim kho cov uniformity ntawm raw khoom sib tov.
3. Kev hloov dej noo: txhawm rau tswj cov dej hauv cov chiv, kev hloov dej noo yog tsim nyog rau cov khoom siv raw, xws li cov quav tsiaj, uas muaj cov dej ntau dhau los yog tsawg.Feem ntau, cov ntaub ntawv nyoos uas ntub dhau yuav tsum tau qhuav, lossis cov ntsiab lus noo noo yuav tsum tau ntxiv los ntawm kev ntxiv cov dej kom tsim nyog.
4. Kev sib xyaw ua ke: Hauv ib qho piv txwv, muab cov khoom siv raw uas tau kuaj xyuas, crushing, hloov dej noo, thiab lwm yam txheej txheem ua.Lub hom phiaj ntawm kev sib tov yog ua kom noj qab haus huvcarbon-to-nitrogen ratio, los yog C / N ratio, nyob rau hauv lub compost.Txhawm rau txhawb txoj kev loj hlob thiab kev loj hlob ntawm cov kab mob, qhov zoo tshaj plaws C / N piv yuav tsum nyob ntawm 25: 1 txog 30: 1.
5. Composting: Muab cov ntaub ntawv raw uas tau npaj tseg kom lawv tuaj yeem ferment organically.Txhawm rau tswj cov kab mob zoo tshaj plaws ntawm qhov kub thiab av noo thiab txhawb kev tawg ntawm microbes, cov nplooj lwg yuav tsum tau tig thiab tso cua tsis tu ncua thaum lub sij hawm stacking txheej txheem.
Kev ua thawj zaug ntawm cov khoom siv compost raw yuav ntxiv nrog rau cov qauv hauv qab no ntawm kev kho mob ntxiv rau cov theem tseem ceeb ntawm cov khoom siv raw - kev tshuaj xyuas, crushing, hloov dej noo, xa mus, thiab composting:
Kev tua kab mob ntawm cov khoom siv raw: Cov ntaub ntawv nyoos yuav tsum tau muab tshuaj tua kab mob vim tias lawv yuav muaj cov kab mob phem, kab qe, cov noob nroj, thiab lwm yam. Tshuaj lossis lub cev txhais tau tias decontamination, xws li kev siv tshuaj tua kab mob (xws li kev kho cua kub kub).
Kev kho kom ruaj khov: Txhawm rau txo qis kev phom sij ntawm ib puag ncig kev sib kis, qee qhov kev lag luam pov tseg, sludge, thiab lwm yam, yuav tsum ruaj khov vim tias lawv suav nrog cov khoom tsis zoo xws li cov khoom siv organic thiab cov hlau hnyav.Pyrolysis, anaerobic digestion, redox therapy, thiab lwm yam kev siv feem ntau yog siv rau kev kho kom ruaj khov.
Kev sib xyaw ua ke: Ntau yam ntawm cov khoom siv raw tuaj yeem sib xyaw thiab kho kom zoo thiab cov khoom noj muaj txiaj ntsig ntawm cov khoom siv compost.Piv txwv li, compost cov ntsiab lus ntawm cov organic teeb meem thiab kev noj zaub mov muaj ntau haiv neeg tuaj yeem nce ntxiv los ntawm kev sib txuas hauv nroog cov khib nyiab nrog cov khib nyiab ua liaj ua teb.
Kev kho mob ntxiv: Qee cov tshuaj tuaj yeem muab ntxiv rau hauv cov chiv txhawm rau txhim kho microbial tawg, hloov pH qib, nce cov khoom noj khoom haus, thiab lwm yam, txhawm rau txhim kho qhov zoo thiab cov yam ntxwv ntawm cov chiv.Piv txwv li, ntxiv cov ntoo chips tuaj yeem txhim kho cov compost's aeration thiab muaj peev xwm khaws dej.Ntxiv cov txiv qaub tuaj yeem sib npaug ntawm cov av pH thiab txhawb kev loj hlob ntawm cov kab mob.Koj tuaj yeem ntxiv cov kab mob aerobic lossis anaerobic ncaj qha rau hauv cov chiv kom nrawm nrawm thiab txhim kho nws cov nroj tsuag sab hauv.
Nws yuav tsum tau hais tias muaj ntau ntau yam ntawm cov khoom pib rau industrial composting, thiab ntau yam pib cov ntaub ntawv hu rau ntau yam thawj-theem txheej txheem txheej txheem.Txhawm rau ua kom cov compost zoo thiab ib puag ncig kev nyab xeeb, cov khoom siv raw yuav tsum tau tshuaj xyuas thiab tshuaj xyuas ua ntej ua ntej.Ob peb txoj kev kho mob yuav tsum tau xaiv los ntawm qhov xwm txheej.
