Mapeto a njira yochotsera zimbudzi nthawi zambiri amakhala matope amadzi olimba-amadzi olekanitsa. Kulekanitsa kwamadzi olimba kumatanthawuza njira yochotsa zolimba zomwe zayimitsidwa m'madzi kapena madzi oyipa, kuphatikiza sedimentation, kusefera, kusefera kwa membrane, makina osindikizira, vacuum, ndi centrifuge. Munjira yoyatsidwa ndi zinyalala, kusefera kwa membrane kapena njira za sedimentation nthawi zambiri zimagwiritsidwa ntchito kukwaniritsa kulekanitsa kwamadzi olimba. Microfiltration, kuwunikira, ndi kusefera kwa bedi lakuya kungagwiritsidwe ntchito kupititsa patsogolo tinthu tating'ono tating'ono tolimba m'chimbudzi.
Pakati pa matekinoloje olekanitsa olimba-zamadzimadzi omwe amagwiritsidwa ntchito kawirikawiri, akasinja a sedimentation amakhala m'dera lalikulu, ndi ovuta kuwasamalira, amatenga nthawi yayitali, ndi okwera mtengo, ndipo sali oyenera zipangizo zophatikizika. Njira zosefera ma membrane nthawi zambiri zimagwiritsa ntchito nembanemba za MBR, zomwe zimakhala ndi malo ochepa komanso zimakhala ndi zosefera zabwino. Komabe, ma membrane a MBR ndi ovuta kuwasamalira, amakhala ndi mphamvu zambiri, ndipo amafunikira ndalama zambiri.
Poganizira zovuta zaukadaulo wolekanitsa wamadzi olimba omwe alipo, monga malo akuluakulu apansi, kugwiritsa ntchito mphamvu zambiri, komanso kukonza zovuta, HYHH yapanga mtundu watsopano wamagetsi okhazikika komanso otsika otsika olimba-zamadzimadzi olekanitsa - kusefera kwa bakiteriya. dongosolo. Chipangizo chowunikira mabakiteriya chidapangidwa kutengera zomwe zidachitika pazida zamagetsi za biofilm sedimentation, kuthana ndi zovuta zogwiritsa ntchito mphamvu zambiri komanso kukonza zovuta za nembanemba ya MBR, ndikusewera kwathunthu pazabwino zogwiritsa ntchito mphamvu zochepa, zodzichitira zonse, komanso kukonza kosavuta kwa chipangizo choyezera bakiteriya.
Gulu lowonera mabakiteriya limapangidwa ndi ma biofilms angapo odzipangira okha. Biofilm yodzipangira yokha imapangidwa ndi zida zapadera za hydrophilic monga maziko. Kumayambiriro kwa njira yolekanitsa madzi amatope, imapangidwa ndi hydraulic cross-flow, microbial secretion ya EPS ndi kuyika kwachilengedwe kwamagulu a mabakiteriya amtundu wa micro-net base. Biofilm yodzipangira yokha imagwiritsa ntchito mphamvu ya osmotic ya madzi kuti ikwaniritse kulekanitsa kwamadzi olimba opanda mphamvu, ndipo imakhala ndi zotsatira zolekanitsa zofanana ndi zowonongeka za microfiltration / ultrafiltration. Nthawi yomweyo, imatha kulekanitsa nthawi ya Sludge Retention Time (SRT) kuchokera ku Hydraulic Retention Time (HRT), yomwe ndi yabwino kuwongolera magwiridwe antchito.
Zosintha zaukadaulo
Kuthamanga: 50-60 LMH
Kusinthikanso: kuwotcha kwa gasi (kosavuta)
Kupanga madzi: kupanga madzi opanda mphamvu
Kugwiritsa ntchito mphamvu: kutsika kwambiri (1-3 kW·h/m3)
Kukonza: zosavuta (palibe kuyang'aniridwa ndi munthu)
Kukhazikika: 5000-8000 mg/L
Kuchuluka kwamphamvu: 1000 NTU
Kutulutsa kwamphamvu:
MawonekedweKuthamanga kwakukulu komanso kuthamanga kwa kusefera mwachangu;
Zolemba zazing'ono, kutumidwa mwachangu, zokonzeka kugwiritsidwa ntchito pambuyo pa kukhazikitsa;
Kutulutsa kwamadzi kwakukulu pagawo la unit;
Kupanga ma modular ndikotheka, kumathandizira kukulitsa, kukonzanso ndi kusamutsa malo osungiramo zimbudzi zomwe zilipo kale.
