Ioksijini yaziwa njengenye yezona gesi zibalulekileyo ezikhoyo kwindalo.Ngoku ikwasetyenziswa kwiinkqubo zolawulo lwenkunkuma kwinqanaba loshishino.Ioksijini idluliselwa kumanzi amdaka ukuze kukhule ibhaktheriya kunye neentsholongwane ezincinci ezikhula apho, ezinokuqhekeza izinto ezichithwayo ezinyibilikisiweyo kwaye zithintele ukwakheka kweegesi zemethane kunye nehydrogen sulfide.Emva kwesenzo sebhaktheriya kwiimveliso zenkunkuma, ubunzima buhlala phantsi kwetanki yamanzi.Le nkqubo ibizwa ngokuba yi-aeration, esebenza kakhulu kulawulo lwamanzi amdaka.I-HangZhou Sihope ibonelela ngejenereyitha ye-oksijini enokubonelela ngeoksijini ecocekileyo yokucocwa kwamanzi kunye namanzi amdaka.

Izibonelelo ezinikezelwa yioksijini kulawulo lwamanzi amdaka

Iplanti yeoksijini ebonelelwa nguHangZhou Sihope ibonelela ngeoksijini esulungekileyo ukuya kuthi ga kwi-96%, enokusetyenziselwa ukucoca amanzi amdaka.Ukucocwa kwamanzi amdaka ngokudlula ioksijini kuneengenelo ezininzi, ezidweliswe ngezantsi.

• Ivumba elibi liyaphela ngokupheleleyo emanzini amdaka

• Iphelisa iikhemikhali eziphilayo eziguqukayo, ezifana nebenzene okanye i-methanol, emanzini

• Yandisa ubungakanani beoksijini enyibilikisiweyo emanzini

• Ikhupha i-ammonia enyibilikisiweyo emanzini

• Ukunciphisa ungcoliseko lwamanzi ngokomda wemvume ye-NPDES

• Ukuphucula ubomi obude benkqubo yolawulo lwamanzi

• Akukho mfuneko yokuphucula umzi-mveliso wamanzi amdaka ukuze uhlangabezane nemida evumelekileyo

• Ukurisayikilishwa okukhawulezileyo kwamanzi acociweyo asuka kumzi-mveliso

• Ukwehliswa kweendleko zamandla okusebenzisa umzi-mveliso wamanzi amdaka

I-HangZhou Sihope yenza ngokwezifiso isityalo se-oksijini se-PSA esikuyo ngokweemfuno zomthengi.Ekubeni inika i-oksijini ngokuqhubekayo kwisityalo samanzi amdaka, kukulungele ukuphatha inkqubo yokulawula amanzi.Ioksijeni iphonswa nje kwitanki yamanzi ngombhobho, kwaye ubude balo mbhobho buxhomekeke ekuphakameni komgangatho wamanzi kwitanki.Le ndlela yokubonelela ngeoksijini yamanzi kunye nokucocwa kwamanzi amdaka itshiphu kakhulu kunokuthenga iisilinda zeoksijini kunyango lokungenisa umoya.Igcina ubunzima bokusebenzisa izixhobo ezinzima apho kufuneka kuzaliseke iindlela ezininzi zokudlulisa i-oksijini kwisityalo samanzi.I-oksijini ecocekileyo kwiidosi eziphantsi ingasetyenziswa kunyango oluphambili kunye nolwesibini lwamanzi amdaka.
