Fasahar MBR tana Sauya Maganin Ruwan Shara tare da Babban inganci

MBR (Membrane Bio-Reactor) tsari ne mai inganci mai inganci wanda ke haɗa maganin ilimin halitta na gargajiya (kamar hanyar sludge mai kunnawa) tare da fasahar rabuwa da membrane. Mahimmancinsa shine maye gurbin tanki na al'ada na sakandare na gargajiya tare da ultrafiltration ko microfiltration membrane (girman pore 0.01 ~ 0.4 μm) don cimma rabuwar ruwa mai slurry da kuma inganta ingantaccen ingancin lokaci guda. Fasaha ta MBR membrane ta farko tana kawar da gurɓataccen kwayoyin halitta a cikin ruwa ta hanyar sludge mai kunnawa, sannan ta yi amfani da nau'ikan membrane don tilasta watsewar da aka kunna da galibin daskararrun daskararrun da aka dakatar a cikin bioreactor don cimma rarrabuwar ruwa mai tsafta da sludge mai kunnawa, ta haka yana ƙarfafa tasirin biochemical da inganta tasirin jiyya.

Tsarin jiyya na MBR yana da tasiri mai mahimmanci akan maganin COD a cikin sharar gida na masana'antar takin mai magani na nitrogen, kuma nau'ikan kwayoyin halitta suna da ɗan gajeren lokaci na lafiya da haɓakawa, kuma tasirin ya tabbata daga rana ta uku. A cikin duka matakan jiyya na kwanciyar hankali da matakin aiki na yau da kullun, ana iya kiyaye ƙimar cirewar COD, kuma adadin cirewa ya fi 90%. Ana sarrafa matsakaicin COD fitarwa a ƙasa 30mg/L.

MBR shine ingantaccen hadewar fasahar rabuwar membrane da hanyar jiyya ta ilimin halitta, kuma asalinsa shine maye gurbin tanki na sedimentation na biyu a cikin hanyar sludge da aka kunna tare da fasahar rabuwa da membrane don rabuwar ruwa mai ƙarfi. Wannan tsari ba wai kawai ya cimma manufar slurry rabuwa ba, har ma yana da fa'idodi marasa misaltuwa na tsarin gargajiya na kula da najasa:

1. Ingantacciyar rabuwar ruwa mai ƙarfi, tasirin rabuwa yana da kyau fiye da na tanki na al'ada na al'ada, ingancin ruwa mai ƙazanta yana da kyau, ƙaƙƙarfan da aka dakatar da turbidity yana kusa da sifili, kuma ana iya sake amfani da shi kai tsaye, fahimtar sake amfani da najasa.

2. A m interception sakamako na membrane sa microorganisms gaba daya tarko a cikin bioreactor, gane cikakken rabuwa da reactor na'ura mai aiki da karfin ruwa riƙewa lokaci (HRT) da sludge shekaru (SRT), da kuma aiki iko ne m da kuma barga.

3. Saboda MBR hada da aeration tank da sakandare sedimentation tanki na gargajiya najasa magani a cikin daya, da kuma maye gurbin duk aiwatar da wurare na jami'a jiyya, zai iya ƙwarai rage bene yankin da kuma ajiye farar hula injiniya zuba jari.

4. Yana da kyau ga shiga tsakani da haifuwa na kwayoyin nitrifying, kuma tsarin yana da babban tasiri na nitrification. Ta hanyar canjin yanayin aiki, yana iya samun aikin deammonization da cirewar phosphorus.

5. Saboda shekarun laka na iya zama tsayi sosai, ana inganta haɓakar ƙasƙanci na kwayoyin halitta mai lalacewa.

6. The reactor aiki a karkashin high volumetric load, low sludge load da dogon sludge shekaru, da saura sludge fitarwa ne sosai low.

7. Tsarin ya gane kulawar PLC, kuma aiki da gudanarwa sun dace
