Ngokusho kokwethulwa kwezihloko zethu zangaphambilini, ngesikhathi senqubo yokwenza umquba, ngokuqiniswa kwemisebenzi ye-microbial endabeni, lapho ukushisa okukhishwe ama-microorganisms abola izinto eziphilayo kukhulu kunokusetshenziswa kokushisa komquba, izinga lokushisa lomquba lizokhuphuka. .Ngakho-ke, izinga lokushisa liyipharamitha engcono kakhulu yokwahlulela ukushuba komsebenzi we-microbial.
Ukushintsha kwezinga lokushisa kungathinta ukukhula kwama-microorganisms.Ngokuvamile sikholelwa ukuthi ukusebenza kahle kokuwohloka kwamagciwane anezinga lokushisa eliphezulu odabeni lwemvelo kungaphezulu kwalokho kwamagciwane e-mesophilic.Umquba wanamuhla we-aerobic osheshayo nosezingeni eliphezulu usebenzisa lesi sici.Esigabeni sokuqala sokwenza umquba, izinga lokushisa lomzimba womquba liseduze nezinga lokushisa elizungezile, ngemva kwezinsuku ezingu-1 ~ 2 zesenzo sebhaktheriya ye-mesophilic, izinga lokushisa lokufaka umquba lingafinyelela izinga lokushisa elifanele lika-50 ~ 60 °C kumagciwane asezingeni eliphezulu. .Ngokwalokhu kushisa, inqubo engenangozi yokwenza umquba ingaqedwa ngemva kwezinsuku ezingu-5–6.Ngakho-ke, lapho kwenziwa umquba, izinga lokushisa le-windrow yomquba kufanele lilawulwe phakathi kuka-50 no-65 °C, kodwa lingcono ku-55 kuya ku-60 °C, futhi akufanele lidlule ku-65 °C.Lapho izinga lokushisa lidlula ku-65 °C, ukukhula kwama-microorganisms kuqala ukuvinjelwa.Futhi, amazinga okushisa aphezulu angadla ngokweqile izinto eziphilayo futhi ehlise izinga lomkhiqizo womquba.Ukuze kuzuzwe umphumela wokubulala amagciwane e-pathogenic, ohlelweni lwedivayisi (isistimu ye-reactor) kanye nesistimu yokwenza umquba wokungenisa umoya omile, isikhathi lapho izinga lokushisa langaphakathi lesitaki lingaphezu kuka-55 °C kufanele libe yizinsuku ezi-3.Ohlelweni lokuhlanganisa inqwaba ye-windrow, izinga lokushisa langaphakathi lesitaki likhulu kuno-55°C okungenani izinsuku eziyi-15 futhi okungenani izinsuku ezi-3 ngesikhathi sokusebenza.Ohlelweni lwe-bar-stack, isikhathi lapho izinga lokushisa langaphakathi lenqwaba ye-windrow lingaphezulu kuka-55 °C okungenani izinsuku eziyi-15, futhi inqwaba ye-windrow efaka umquba izophendulwa okungenani izikhathi ezi-5 ngesikhathi sokusebenza.
Ngokusho kwejika lokushisa elidonswayo lomquba ojwayelekile, inqubekelaphambili yenqubo yokuvutshelwa ingahlulelwa.Uma izinga lokushisa elilinganisiwe liphambuka ejikeni elivamile lokushisa, libonisa ukuthi umsebenzi wama-microorganisms uphazanyiswa noma uvinjelwa izici ezithile, futhi izici ezivamile ezithonya ngokuyinhloko ukunikezwa komoya-mpilo kanye nokuqukethwe komswakama kadoti.Ngokuvamile, ezinsukwini ezi-3 kuya kwezi-5 zokuqala zokuvundisa, inhloso enkulu yokungenisa umoya ukunikeza umoya-mpilo, ukwenza ukusabela kwe-biochemical kuqhubeke kahle, futhi kufezeke inhloso yokwandisa izinga lokushisa lomquba.Uma izinga lokushisa lomquba likhuphuka lifika ku-80~90℃, lizoba nomthelela omubi ekukhuleni nasekukhiqizeni ama-microorganisms.Ngakho-ke, kuyadingeka ukwandisa izinga lokungena komoya ukuze kususwe umswakama nokushisa emzimbeni womquba, ukunciphisa izinga lokushisa lomquba.Ekukhiqizeni kwangempela, ukulawulwa kwezinga lokushisa okuzenzakalelayo kuvame ukuqedwa ngohlelo lwempendulo yokunikeza izinga lokushisa komoya.Ngokufaka isistimu yempendulo yezinga lokushisa emzimbeni ostakiwe, lapho izinga lokushisa langaphakathi lomzimba olayishiwe lidlula u-60 °C, ifeni iqala ngokuzenzakalelayo ukunikeza umoya emzimbeni ostakiwe, ngaleyo ndlela Ukushisa kanye nomhwamuko wamanzi kuwindi lokuvula umnyango uyakhishwa ukuze wehlise umoya. ukushisa kwenqwaba.Kumquba wohlobo lwenqwaba ye-windrow ngaphandle kwesistimu yokukhipha umoya, ukuphenduka komquba okuvamile kusetshenziselwa ukuzuza ukungena komoya kanye nokulawula izinga lokushisa.Uma ukusebenza kuyinto evamile, kodwa izinga lokushisa lomquba liqhubeka nokwehla, kungatholakala ukuthi umquba ungene esiteji sokupholisa ngaphambi kokuphela.
