Tsarin aiki da sabon tsari na membrane bioreactor MBR

Lokaci: 2020-04-16 hits: 42

Membrance Bioreactor Reactor (wanda aka rage shi azaman MBR) wani sabon tsari ne na kula da ilimin halittar ruwa wanda yake kunshe da rabuwa da membrane da fasahar kula da ilimin halittu.

 

Akwai membranes da yawa, ana rarrabasu gwargwadon tsarin rabuwa, gami da membranes dauki, membranes ion, da membranes permeable; gwargwadon yanayin membranes, akwai membranes na halitta (membranes na halitta) da membranes na roba (membranes Organic da meorranic membranes); Ana rarrabe nau'ikan fasali zuwa nau'in lebur, nau'in bututu, nau'in karkace da nau'in fiber mai ɗorewa.

 

Tun daga 1980s, membrane bioreactors sun karu sosai kuma sun zama ɗayan wuraren bincike. A halin yanzu, anyi amfani da fasahar a fiye da kasashe goma kamar Amurka, Jamus, Faransa da Masar, tare da sikelin daga 6m3 / d zuwa 13000m3 / d.


 

China's research on MBR is less than ten years, but progress is very rapid. Domestic research on MBR can be roughly divided into several aspects:

 

(1) Binciko haɗuwa da hanyoyin magani daban-daban da ramuwar rabuwa. Tsarin kulawa da nazarin halittu yana gudana daga hanyar sludge na kunnawa zuwa hanyar hadawar hada hada abu, hanyar biofilm, haɗe-haɓen tsari da kuma haɗuwa biyu-lokaci na ɓacin rai da tsari na biofilm Anaerobic;

 

(2) Bincike kan dalilai, kayan aiki da samfuran lissafi wadanda suka shafi tasirin magani da fombur fomb, bincika yanayin aiki da ya dace da sigogin aiwatarwa, rage fombar membrane gwargwadon yiwuwa, da inganta haɓaka aiki da daidaituwar aiki na ɗakunan membrane;

 

(3) Fadada aikin aikace-aikacen MBR. Abun bincike na MBR yana fadadawa daga shararar gida zuwa ruwa mai dauke da ruwa (matattarar abinci, ruwan sha giya) da kuma matattarar sharar masana'antu (matattarar ruwan sha, bugawa da sanya ruwan danshi, da sauransu), amma kula da gurbataccen gida shine Ubangiji.

 

Waɗanne halaye ne na aikin MBR?

 

Idan aka kwatanta da fasahar kulawa da ruwan sha na gargajiya, MBR yana da manyan halaye kamar haka:

 

1. Ingantaccen isasshen ruwa mai-rarrabawa, rabe raben ya fi na tanki na gargajiya wanka, ingancin ruwa mai kyau, ingancin ruwa mai tsafta da ɓarna yana kusa da sifiri, ana iya sake amfani da shi kai tsaye, tare da sanin sake ma'adinin na shara.

 

2. Aiki mai ma'ana a cikin membrane yana bawa microorganisms damar shiga tarkon gaba daya, tare da samun cikakkiyar rabuwa da lokacin zama na hydraulic (HRT) da tsufa mara kyau (SRT), kuma aikin sarrafawa yana da sassauci kuma yana tabbata.

 

3. Tunda MBR ya haɗu da tanki na taneration da na biyu na tanki na shara na gargajiya a cikin ɗayan, kuma ya maye gurbin duk hanyoyin aiwatar da kula da manyan makarantu, zai iya rage yankin sosai da adana jarin da ke cikin injin.

 

4. Koyarwa zuwa ga fitarwa da haifuwa na ƙwayoyin nitrifying, tsarin yana da ingantaccen ingantaccen nitrification. Hakanan yana iya samun ayyuka na lalata da kuma lalata abubuwa ta hanyar sauya yanayin aiki.

 

5. Tun da shekarun laka na iya yin tsawo, lalacewar ingantattun kwayoyin halitta na inganta sosai.

 

6. Mai sarrafa wuta ana sarrafa shi a karkashin babban nauyin kaya, mara nauyi mai nauyi da tsayi tsawon shekaru. Ragowar abubuwan da ke fitarwa suna da ƙarancin gaske. Tunda shekarun tsufa zasu iya zama tsawon lokaci, a mahangar, za a iya samun zubarwar sifili.
