1. Okisijeni inopihwa nekusandura mirwi ndeimwe yemamiriro ekutanga ekugadzirwa kwe aerobic fermentation.Basa guru rekushandura:
①Ipa okisijeni kuti ikurumidze kuvirisa maitiro ehutachiona;②Gadzirisa tembiricha yemurwi;③Pumisa murwi.
Kana nhamba yekutendeuka idiki, vhoriyamu yemhepo haina kukwana kupa oxygen yakakwana kune ma microorganisms, izvo zvinokanganisa kukwira kwekushisa kwekuvirisa;kana nhamba yekutendeuka yakanyanyisa, kupisa kwemurwi we compost kunogona kurasikirwa, izvo zvichakanganisa chiyero chekusakuvadza kwekuvirisa.Kazhinji maererano nemamiriro ezvinhu, murwi unoshandurwa 2-3 nguva panguva yekuvirisa.
2. Zviri mukati meorganic matter zvinokanganisa tembiricha yekuchengetera uye kufefetedza uye kupihwa kweokisijeni.
Izvo zviri mukati me organic matter zvakaderera, kupisa kunokonzerwa nekuora hakuna kukwana kusimudzira nekuchengetedza kuwanda kwe thermophilic bacteria mukuvirisa, uye zvakaoma kuti murwi wecompost usvike padanho rekushisa, izvo zvinokanganisa hutsanana uye. kusakuvadza mhedzisiro yekuvirisa.Uyezve, nekuda kwekuderera kweiyo organic zvinhu, zvinokanganisa kushanda kwefetereza uye kukosha kwekushandisa kwezvinhu zvakaviriswa.Kana zviri mukati meorganic matter zvakanyanyisa, huwandu hukuru hweokisijeni hunozodiwa, izvo zvinozokonzeresa kunetsa kutenderedza murwi kuti uwane oxygen, uye zvinogona kukonzera chikamu anaerobic mamiriro nekuda kwekushaikwa kweokisijeni.Iyo yakakodzera organic matter yemukati ndeye 20-80%.
3. The optimum C/N ratio is 25:1.
Mukuvirisa, organic C inonyanya kushandiswa sesosi yesimba kune tupukanana.Yakawanda yeorganic C inoiswa oxidized uye yakaora kuita CO2 uye inonyungudika panguva ye microbial metabolism, uye chikamu cheC chinoumba sero nyaya yezvipembenene pachazvo.Nitrogen inonyanya kupedzwa mukugadzirwa kweprotoplasts, uye iyo inonyanya kukodzera C / N chiyero ndeye 4-30 maererano nezvinodiwa zvinovaka muviri zve microorganisms.Kana chiyero cheC/N che organic matter chasvika gumi, iyo organic matter inoodzwa nema microorganisms pamwero wepamusoro.
Nekuwedzera kwechiyero cheC / N, nguva yekuvirisa yakawedzera kureba.Kana iyo C/N chiyero cheiyo mbishi iri makumi maviri, 30-50, 78, inoenderana nguva yekuvirisa inenge mazuva 9-12, 10-19 mazuva, uye 21 mazuva, asi kana C/N reshiyo yakakura kupfuura 80. Kana : 1, kuvirisa kwakangooma kuita.
Chiyero cheC/N chechimwe nechimwe chekuvirisa mbishi chinowanzo: sawdust 300-1000, mashanga 70-100, raw material 50-80, manyowa evanhu 6-10, manyowa emombe 8-26, manyowa enguruve 7-15, manyowa ehuku 5. -10 , Sewage sludge 8-15.
Mushure mekuita manyowa, chiyero cheC/N chinenge chadzikira zvakanyanya pane chisati chaitwa manyowa, kazhinji 10-20:1.Rudzi urwu rweC/N reshiyo yekuora nekuvirisa ine fetereza iri nani mukurima.
4. Kana hunyoro hwakakodzera hunokanganisa zvakananga kukurumidza kwekuvirisa uye chiyero chekuora.
Pakuvirisa madhaka, mwando wakakodzera wemurwi unosvika 55-65%.Mukushanda kwechokwadi, nzira iri nyore yekutsunga ndeyotevera: bata zvinhu zvakasimba neruoko rwako kuti uite bhora, uye pachava nemararamiro emvura, asi zviri nani kuti mvura irege kudonha.Iyo yakanyanya kufanira mwando yekuvirisa zvinhu mbishi ndeye 55%.
5. Granularity
Okisijeni inodiwa pakuvirisa inopihwa kuburikidza nemapores ezvimedu zvekuvirisa.Iyo porosity uye saizi yepore zvinoenderana nehukuru hwechikamu uye kusimba kwechimiro.Kufanana nebepa, mhuka uye zvidyarwa, uye machira efayibha, kuwanda kuchawedzera kana kuratidzwa kumvura nekumanikidzwa, uye pores pakati pezvimedu zvichadzikiswa zvakanyanya, izvo zvisingaite kuti kufefeterwa uye kupihwa kweokisijeni.Iyo yakakodzera particle size inowanzoita 12-60mm.
6. pH Microorganisms inogona kubereka mupH yakakura, uye pH yakakodzera i6-8.5.Kazhinji hapana chikonzero chekugadzirisa pH panguva yekuvirisa.
