MBR sewage treatment equipment nderimwe zita re membrane bioreactor. Iyo yakasanganiswa sewage yekurapa michina ine advanced tekinoroji. Mune mamwe mapurojekiti ane yakakwira effluent zvinodiwa uye kudzora kwakasimba kwezvinosvibisa mvura, membrane bioreactor inoita zvakanyanya. Nhasi, Liding Environmental Protection, inyanzvi yekugadzira michina yekuchenesa tsvina, ichakutsanangurira chigadzirwa ichi nekunyatsoshanda.
Chinhu chakakosha cheMBR sewage treatment equipment ndiyo membrane. MBR yakakamurwa kuita mhando nhatu: yekunze mhando, yakanyura mhando uye inoumbwa mhando. Zvinoenderana nekuti okisijeni inodiwa mu reactor, MBR yakakamurwa kuita aerobic mhando uye anaerobic mhando. Aerobic MBR ine nguva pfupi yekutanga-up uye yakanaka yekubuda kwemvura, iyo inogona kusangana neyakagadzika kushandiswa kwemvura, asi sludge inobuda yakakwira uye simba rekushandisa rakakura. Anaerobic MBR ine simba shoma rekushandisa, kugadzirwa kwakaderera kwesludge, uye biogas chizvarwa, asi zvinotora nguva yakareba kuti utange, uye kubviswa kwezvinosvibisa hakuna kunaka se aerobic MBR. Zvinoenderana neakasiyana membrane zvinhu, MBR inogona kukamurwa kuita microfiltration membrane MBR, ultrafiltration membrane MBR uye zvichingodaro. Membrane zvinhu zvinowanzoshandiswa muMBR ndeye microfiltration membranes uye ultrafiltration membranes.
Zvinoenderana nekudyidzana pakati pe membrane modules uye bioreactors, MBR yakakamurwa kuita mhando nhatu: "aeration MBR", "kuparadzanisa MBR" uye "kubvisa MBR".
Aerated MBR inonzi zvakare Membrane Aerated Bioreactor (MABR). Iyo aeration nzira yeiyi tekinoroji yakakwirira kune yechinyakare porous kana microporous hombe bubble aeration. Iyo gasi-inopindika membrane inoshandiswa kune bubble-isina aeration kupa oxygen, uye mwero wekushandisa weokisijeni wakakwira. Iyo biofilm iri pamhepo inofema inosangana zvizere netsvina, uye iyo inofema membrane inopa okisijeni kune ma microorganisms akabatanidzwa pairi, uye inonyatso kushatisa zvinosvibisa mumvura.
Iyo yekuparadzanisa mhando MBR inonzi zvakare yakasimba-mvura yekuparadzanisa mhando MBR. Inosanganisa tekinoroji yekuparadzanisa tekinoroji neyechinyakare tsvina yebiological kurapwa tekinoroji. Solid-mvura yekuparadzanisa kushanda zvakanaka. Uye nekuti izvo zviri mukati meyakagadziriswa sludge muaeration tank inowedzera, kugona kwe biochemical reactions kunovandudzwa, uye organic zvinosvibisa zvinowedzera kuderedzwa. Iyo yekuparadzanisa mhando MBR inonyanya kushandiswa mumapurojekiti ekurapa tsvina yeMBR.
Extractive MBR (EMBR) inosanganisa membrane yekuparadzanisa maitiro neanaerobic digestion. Sarudzo membranes inobvisa zvine chepfu kubva mumvura ine tsvina. Anaerobic microorganisms inoshandura organic matter mumvura yetsvina kuita methane, gasi resimba, uye kushandura zvinovaka muviri (senitrogen nephosphorus) kuita mamwe makemikari mafomu, zvichibva zvawedzera kudzoreredza zviwanikwa kubva mumvura yakasviba.
