1. Samar da iskar oxygen ta hanyar jujjuya tari shine ɗayan mahimman yanayi don samar da fermentation na aerobic.Babban aikin juyawa:
①Samar da iskar oxygen don hanzarta aiwatar da fermentation na microorganisms;② Daidaita yawan zafin jiki;③Busar da tari.
Idan adadin jujjuyawa yayi ƙanana, ƙarar samun iska bai isa ba don samar da isasshen iskar oxygen ga ƙwayoyin cuta, wanda zai shafi haɓakar zafin jiki na fermentation;idan yawan juye-juye ya yi yawa, za a iya rasa zafin tarin takin, wanda zai yi tasiri ga rashin lahani na fermentation.Yawancin lokaci bisa ga halin da ake ciki, an juya tari sau 2-3 a lokacin fermentation.
2. Abubuwan da ke cikin kwayoyin halitta suna rinjayar yawan zafin jiki da kuma samun iska da iskar oxygen.
Abubuwan da ke cikin kwayoyin halitta sun yi ƙasa da ƙasa, zafin da ke haifar da lalacewa bai isa ba don ingantawa da kuma kula da yaduwar kwayoyin thermophilic a cikin fermentation, kuma yana da wuya ga takin takin ya isa matakin zafin jiki mai girma, wanda ke shafar tsabta da tsabta. m sakamako na fermentation.Bugu da ƙari, saboda ƙarancin abun ciki na kwayoyin halitta, zai shafi ingancin taki da amfani da ƙimar kayan da aka haɗe.Idan abun ciki na kwayoyin halitta ya yi yawa, za a buƙaci adadin iskar oxygen mai yawa, wanda zai haifar da matsaloli masu amfani wajen jujjuya tari don isar da iskar oxygen, kuma yana iya haifar da yanayin anaerobic na yanki saboda ƙarancin iskar oxygen.Abubuwan da suka dace da kwayoyin halitta shine 20-80%.
3. Mafi kyawun C / N shine 25: 1.
A cikin fermentation, ana amfani da kwayoyin C a matsayin tushen makamashi don ƙananan ƙwayoyin cuta.Yawancin kwayoyin halitta C suna oxidized kuma sun lalace cikin CO2 kuma suna canzawa yayin ƙwayoyin cuta, kuma wani ɓangare na C shine kwayar halitta ta ƙwayoyin cuta da kansu.Nitrogen yafi cinyewa a cikin haɗin protoplasts, kuma mafi dacewa da rabon C/N shine 4-30 dangane da buƙatun sinadirai na ƙwayoyin cuta.Lokacin da rabon C/N na kwayoyin halitta yana kusa da 10, kwayoyin halitta suna lalacewa ta hanyar ƙananan ƙwayoyin cuta a mafi girma.
Tare da karuwar rabon C/N, lokacin fermentation ya daɗe.Lokacin da rabon C / N na albarkatun kasa shine 20, 30-50, 78, daidai lokacin fermentation shine game da kwanaki 9-12, kwanaki 10-19, da kwanaki 21, amma lokacin da rabon C / N ya fi 80. Lokacin: 1, fermentation yana da wuyar aiwatarwa.
C/N rabon kowane fermentation albarkatun kasa yawanci: sawdust 300-1000, bambaro 70-100, albarkatun kasa 50-80, mutum taki 6-10, saniya taki 8-26, alade taki 7-15, kaji taki 5. -10 , Najasa sludge 8-15.
Bayan takin, rabon C/N zai yi ƙasa sosai fiye da wancan kafin yin takin, yawanci 10-20: 1.Irin wannan rabon C/N na rubewa da fermenting yana da ingantaccen ingantaccen taki a aikin gona.
4. Ko danshi ya dace da kai tsaye yana rinjayar saurin fermentation da digiri na lalata.
Don sludge fermentation, dacewar danshi abun ciki na tari ne 55-65%.A cikin ainihin aiki, hanya mai sauƙi na ƙaddara ita ce kamar haka: riƙe kayan aiki tare da hannunka don samar da ball, kuma za a sami alamun ruwa, amma ya fi kyau kada ruwa ya fado.Mafi dacewa danshi don fermentation albarkatun kasa shine 55%.
5. Granularity
Ana ba da iskar oxygen da ake buƙata don fermentation ta cikin pores na fermentation albarkatun albarkatun kasa.A porosity da pore size dogara a kan barbashi size da kuma tsarin ƙarfi.Kamar takarda, dabbobi da shuke-shuke, da fiber yadudduka, da yawa za su karu a lokacin da aka fallasa su da ruwa da matsa lamba, kuma za a rage ramukan da ke tsakanin barbashi da yawa, wanda ba shi da amfani ga samun iska da iskar oxygen.The dace barbashi size ne kullum 12-60mm.
6. pH Microorganisms na iya haifuwa a cikin pH mafi girma, kuma pH mai dacewa shine 6-8.5.Yawancin lokaci babu buƙatar daidaita pH yayin fermentation.
