Fuding kurengera ibidukikije: ibikorwa byumushinga wimyanda yo mumijyi ibikoresho byahujwe

Iterambere ry’ubukungu bw’icyaro n’ubwiyongere bw’abaturage, imyanda y’imyanda yo mu cyaro nayo iriyongera. Mu rwego rwo kurengera ibidukikije mu cyaro n’ubuzima bw’abaturage, hagomba kubakwa ibikoresho byinshi byo gutunganya imyanda kugira ngo itunganyirize imyanda yo mu ngo. Umujyi wimyanda yimyanda yibikoresho byahujwe mugihe cyamateka, ko ibikorwa byayo neza neza, uyumunsi kubyumva.

Ibikoresho byahujwe n’uruganda rutunganya imyanda yo mumijyi rukoresha cyane cyane uburyo bwo gutunganya ibinyabuzima bya AO kugirango bikureho imyanda ihumanya na azote ya amoniya. Ihame ryakazi ryayo riri mubyiciro A, kubera ubwinshi bwibintu kama mumyanda, mikorobe iba iri muri hypoxia, muriki gihe, mikorobe ni mikorobe zifite ubushobozi, zizabora azote kama mumyanda muri NH? -N, mugihe ukoresha karubone kama nkumuterankunga wa electron, OYA? -N 、 OYA? -N ihinduka N? Kandi ukoresheje amwe mumasoko ya karubone na NH? -N muguhuza ibikoresho bishya bya selile.

Kubwibyo, icyiciro A pisine yibikoresho byo gutunganya imyanda ihuriweho ntabwo ifite gusa umurimo runaka wo kuvanaho kama, kugabanya umutwaro kama wikigega cya aerobic cyakurikiyeho, gifasha nitrifisiyasi, ariko kandi gishingiye kumurengera mwinshi wibintu kama bihari muri amazi mbisi kugirango arangize denitrification, hanyuma arandure burundu azote ya azote.

Mu cyiciro cya O, kubera ko kwibumbira hamwe kw’ibinyabuzima byagabanutse cyane, ariko ibikoresho byo gutunganya imyanda bihuriweho biracyafite umubare munini wibintu kama kandi NH? -N birahari. Kugirango turusheho kwangirika kwa okiside yibintu kama, kandi nurangiza karuboni, ingufu za nitrifisiyasi zigenda neza, ikigega cya aerobic biologique contact oxyde oxyde hamwe nuburemere buke kama gishyirwa kurwego rwa O.

Microorganismes zo mu kirere hamwe na bagiteri zo mu bwoko bwa ogisijeni zibaho cyane cyane mu cyiciro cya O-pisine y'ibikoresho byo gutunganya imyanda ihuriweho. Ese mikorobe yo mu kirere ibora ibinyabuzima muri CO? H? O, karubone idafite ingufu cyangwa CO mu kirere? Nkintungamubiri, Ese OYA mumyanda? -N 、 OYA? -Ntizahinduka N?. Amazi ya O pisine atemba muri pisine, atanga imashini ya electron kuri pisine, hanyuma amaherezo ikuraho umwanda wa azote binyuze muri denitrification.

Ibikoresho byahujwe n’ibikorwa byo gutunganya imyanda yo mu mijyi mu turere dutandukanye bigomba guhitamo ikoranabuhanga rikwiye ryo gutunganya imyanda ikurikije imiterere yihariye y’icyaro, kandi igomba no gutekereza ku buryo bushoboka, ubukungu n’ingaruka ku bidukikije by’ikoranabuhanga. Ibikoresho byo gutunganya imyanda byangiza ibidukikije birashobora guhuza ibikenerwa na toni 0.3 zihuriweho na toni 10,000 zo gutunganya imyanda, kandi ibicuruzwa 9 bishobora gutoranywa mu bwisanzure, ukurikije ibintu bitandukanye.
