Fermentation Technology of Cow Manure Organic Fertilizer

Tseem muaj ntau thiab ntau qhov loj thiab me ua liaj ua teb.Thaum ua tau raws li tib neeg cov nqaij xav tau, lawv kuj tsim cov tsiaj nyeg thiab tsiaj txhu ntau.Kev kho kom tsim nyog ntawm cov quav tuaj yeem tsis tsuas yog daws qhov teeb meem ntawm ib puag ncig muaj kuab paug, tab sis kuj tig pov tseg.Weibao tsim cov txiaj ntsig zoo heev thiab tib lub sijhawm tsim cov txheej txheem kev ua liaj ua teb.

hais txog carbon-muaj cov ntaub ntawv organic uas feem ntau muab los ntawm cov nroj tsuag thiab / los yog tsiaj txhu thiab fermented thiab decomposed.Lawv txoj haujlwm yog txhawm rau txhim kho av fertility, muab cov zaub mov noj, thiab txhim kho qoob loo zoo.Nws yog tsim rau cov organic chiv ua los ntawm cov tsiaj txhu thiab nqaij qaib manure, tsiaj txhu thiab cov nroj tsuag residues thiab tsiaj txhu thiab nroj tsuag khoom, uas yog fermented thiab decomposed.

Cov ntsiab lus tseem ceeb ntawm nyuj manure yog tsawg.Nws muaj 14.5% cov organic teeb meem, 0.30 ~ 0.45% nitrogen, 0.15 ~ 0.25% phosphorus, 0.10 ~ 0.15% potassium, thiab siab cellulose thiab lignin cov ntsiab lus.Muaj ntau cov organic teeb meem uas nyuaj rau decompose nyob rau hauv nyuj dung, uas muaj txiaj ntsig zoo rau kev txhim kho cov av.

Cov txheej txheem ntau lawm ntawm nyuj manure organic chiv:

Fermentation → crushing → stirring and mixing → granulation → drying → cooling → screening → packing and warehousing.

1. Fermentation:

Txaus fermentation yog lub hauv paus rau kev tsim cov organic chiv zoo.Lub tshuab tig lub tshuab ua kom paub meej fermentation thiab composting, thiab muaj peev xwm paub tau ntau pawg tig thiab fermentation, uas txhim kho qhov ceev ntawm aerobic fermentation.

2. Crushing:

Lub grinder yog dav siv nyob rau hauv cov organic chiv ntau lawm, thiab muaj ib tug zoo crushing nyhuv ntawm ntub raw cov ntaub ntawv xws li nqaij qaib quav thiab sludge.

3. Kev sib tw:

Tom qab cov khoom siv raw yog crushed, nws yog tov nrog lwm cov ntaub ntawv pab tusyees thiab ces granulated.

4. Granulation:

Cov txheej txheem granulation yog qhov tseem ceeb ntawm cov organic chiv ntau lawm kab.Cov organic chiv granulator ua tiav cov khoom zoo sib xws los ntawm kev sib xyaw ua ke, kev sib tsoo, inlay, spheroidization, granulation, thiab densification.

5. Qhuav thiab txias:

Lub tshuab ziab khaub ncaws ua rau cov khoom sib cuag nrog cov cua kub thiab txo cov dej noo ntawm cov khoom.

Thaum txo qhov kub ntawm cov pellets, lub nruas txias txo cov dej ntawm cov pellets dua, thiab kwv yees li 3% ntawm cov dej tuaj yeem raug tshem tawm los ntawm cov txheej txheem txias.

6. Kev tshuaj ntsuam:

Tom qab txias, tag nrho cov hmoov thiab cov khoom tsis tsim nyog tuaj yeem raug tshuaj xyuas los ntawm lub nruas sieving tshuab.

7. Ntim:

Qhov no yog txheej txheem tsim khoom kawg.Lub tshuab ntim khoom ntim tsis siv neeg tuaj yeem ntsuas qhov hnyav, thauj thiab kaw lub hnab.

Taw qhia rau cov cuab yeej tseem ceeb ntawm nyuj dung organic chiv ntau lawm kab:

1. Cov khoom siv fermentation: trough hom tig tshuab, crawler hom tig tshuab, saw phaj tig thiab ntuav tshuab

2. Cov khoom siv crusher: semi-ntub khoom crusher, ntsug crusher

3. Cov khoom siv tov khoom: kab rov tav tov khoom, lauj kaub tov khoom

4. Cov cuab yeej tshuaj ntsuam xyuas: nruas tshuaj ntsuam tshuab

5. Cov khoom siv granulatorDaim ntawv thov: txhuam hniav granulator, disc granulator, extrusion granulator, nruas granulator

6. Cov khoom siv tshuab ziab khaub ncaws: nruas tshuab ziab khaub ncaws

7. Cov khoom siv txias txias: drum cooler

8. Cov cuab yeej pabcuam: quantitative feeder, automatic quantitative packing machine, siv conveyor.

Feem ntau los ntawm cov hauv qab no los tswj cov txheej txheem fermentation:

Cov dej noo:

Txhawm rau kom ntseeg tau tias qhov kev vam meej ntawm kev sib xyaw ua ke thaum lub sij hawm composting, tus nqi ntawm cov dej hauv thawj theem ntawm composting yuav tsum tau khaws cia ntawm 50-60%.Tom qab ntawd, cov dej noo yog khaws cia ntawm 40% mus rau 50%.Hauv txoj ntsiab cai, tsis muaj cov dej ntws tawm tuaj yeem tawm.Tom qab fermentation, cov dej noo ntawm cov ntaub ntawv raw yuav tsum tau tswj hauv qab 30%.Yog tias cov ntsiab lus noo noo siab, nws yuav tsum tau qhuav ntawm 80 ° C.

Kev tswj qhov kub thiab txias:

Kub yog qhov tshwm sim ntawm microbial kev ua haujlwm.Stacking yog lwm txoj hauv kev los tswj qhov kub thiab txias.Los ntawm kev xa cov pawg, qhov ntsuas kub ntawm pawg tuaj yeem tswj tau zoo kom ua kom cov dej ntws tawm thiab tso cai rau huab cua ntshiab nkag mus rau pawg.Los ntawm kev hloov pauv tas li, qhov kub thiab txias lub sijhawm ntawm fermentation tuaj yeem tswj tau zoo.

Carbon rau nitrogen ratio:

Tsim nyog cov pa roj carbon thiab nitrogen tuaj yeem txhawb nqa cov fermentation du ntawm compost.Cov kab mob tsim microbial protoplasm nyob rau hauv cov txheej txheem fermentation.Cov kws tshawb fawb pom zoo kom cov compost tsim nyog C / N ntawm 20-30%.

Cov pa roj carbon mus rau nitrogen piv ntawm cov organic compost tuaj yeem hloov kho los ntawm kev ntxiv cov pa roj carbon ntau lossis cov tshuaj nitrogen siab.Qee cov ntaub ntawv xws li straw, nroj tsuag, ceg tuag thiab nplooj tuaj yeem siv los ua cov pa roj carbon ntau ntxiv.Nws tuaj yeem txhawb kev loj hlob thiab kev loj hlob ntawm cov kab mob thiab ua kom cov qoob loo loj hlob tuaj.

tswj pH:

Tus nqi pH cuam tshuam rau tag nrho cov txheej txheem fermentation.Nyob rau hauv thawj theem ntawm composting, tus nqi pH yuav cuam tshuam cov kev ua ntawm cov kab mob.
