Biological wastewater treatmentndiyo nzira yehutsanana inonyanya kushandiswa pasi rose.Iyo tekinoroji inoshandisa marudzi akasiyana ebhakitiriya uye mamwe ma microorganisms kurapa uye kuchenesa mvura yakasvibiswa.
Kugadziriswa kwemvura yakasviba kwakakosha zvakaenzana kune hutano hwevanhu uye kuchengetedza kwezvakatipoteredza.Muchokwadi, kushandiswa kweaya mabhakitiriya anomhanyisa kurapwa kwekusvibiswa kudiki kwepasi: decontamination plants.Izvi zviri nani pane kurega rwizi ruchibata nazvo, nekuti kunyangwe iri nzira yekuchenesa imwe chete inoitika muzvisikwa, huwandu hwekusvibiswa hunoburitswa nhasi hwakanyanya kwazvo kuchengetedza kutenderera kwechisikigo.Nokudaro, mashizha ekuchenesa tsvina anodzivirira eutrophication yenzizi uyewo kudzivirira kupararira kwezvirwere.

Utachiona huri pamwoyo pekuita uku.Pakupedzisira, sirasi yekuchenesa tsvina ipurazi inokura microorganisms pamwero mukuru.
Mabhakitiriya anogara kupi?
Kwese kwese, kubva kumvura inosvika painogadziriswa chirimwa kuenda kunzvimbo yekubuda.Iwo maparamendi ekushanda akaiswa mutangi yekurapa anokanganisa kuvandudzwa kweakasiyana masikirwo zvimiro uye mhando dzinovagadzira.Kusiyana nekushandiswa kwema monocultures, boka iri rema microorganisms rakafumiswa mumarudzi akawanda uye rinogona kuwana mazinga akakwirira e biodegradation pane zvakasiyana-siyana zve substrates.Ichi ndicho chikonzero chikuru chinokanganisa kunaka kwe a

Kazhinji, zvipenyu izvi zvinounganidza uye kudzika kuita zvinhu seshizha zvinonzi flocs mune yemahara tsika.Aya macroscopic floe ane mhenyu uye akafa maseru ebhakitiriya, fungi, protozoa uye metabolites.Vanoungana vakatenderedza zvinhu zvakaturikwa izvo zvinodya pazviri.Iyi ndiyo nyaya, semuenzaniso, ine activated slurries.Uyezve, mutsika dzakasimba, akafanana biofilms akaumbwa pakubata kumeso.Semuenzaniso, biofilters uye biodisc itsika dzakagadziriswa.
Zvimwe zvidyarwa zvine UV reactors kana chlorine gasi jekiseni kubvisa mabhakitiriya achiripo mumvura inobuda asati abuda munzizi.Izvi ndizvo zvinoitika muAustralia neNew Zealand.
Ma microbes aya ndivanaani?
Kutanga, tisati tanzwisisa kuti ndivanaani, tinofanira kunzwisisa maparameter anobata kukura kwavo.Kutanga, nzvimbo yejografi.Chechipiri, rudzi rwedhamu iro mabhakitiriya ari kukura mariri. Chechitatu maitiro emvura yetsvina inopinda mufekitari.Pakupedzisira, maitiro ekushanda ehurongwa, akadai seaeration, agitation, chemical injection.Zvese izvi zvinhu zvinoburitsa kuwanda kusiyanisa pakati pe autotrophic uye heterotrophicutachiona.
Kupisa kunogona kukanganisa kuvapo kwemamwe marudzi.Saka, mhedzisiro yenzvimbo yenzvimbo inogona kukanganisa kuumbwa kwemarudzi.Nekune rimwe divi, semuenzaniso muindasitiri, kuvepo kwezvipembenene zvinonyatsotsanangurwa zvinogona kutsanangurwa nekugona kwavo kuodegrade zvikamu zvemvura inoraswa mumaindasitiri.
Utachiona hunoiswazve mumapoka maererano nenzira yavanowana nayo oxygen.Mukurapa kwemvura yetsvina, mabhakitiriya anoshandiswa kurapa mvura yetsvina achipinda muchirimwa chekurapa akakamurwa kuva marudzi matatu: aerobic bacteria, anaerobic bacteria uye facultative bacteria.
Migumisiro yavo nemhinduro
Kuvapo kwebhakitiriya yakaipa (kana kushomeka kwayo) kunogona kukonzera, pakati pezvimwe:
Anaerobic digester biogas kunyatsoshanda kwakaderera
Kusafamba zvakanaka uye sedimentation
