Ngokuthuthuka okuqhubekayo komnotho, ukungcoliswa kwamanzi sekubi kakhulu.Ayanda amakhemikhali ayingozi emanzini.Izindlela ezivame ukusetshenziswa zokwelashwa okukodwa kwamanzi, ezifana nezomzimba, zamakhemikhali, zebhayoloji, njll. zinzima ukuyelapha.Kodwa-ke, izindlela zokubulala amagciwane kanye nezindlela zokuhlanza ze-O3, i-UV, i-H2O2, ne-Cl2 zonke zinomphumela onganele, nekhono le-oxidizing alinamandla, futhi inokusilela ekukhetheni ukuhlangabezana nezidingo zokucubungula.Sihlanganisa ubuchwepheshe basekhaya nabangaphandle futhi samukela i-UV, i-photocatalysis, i-O3, i-oxidation ethuthukisiwe, ukuxuba okusebenzayo, isiqandisi nobunye ubuchwepheshe ukuze sithuthukise futhi sikhiqize isizukulwane esisha semikhiqizo ye-AOP (inqubo ye-oxidation nama-hydroxyl radicals njengesisetshenziswa esiyinhloko ekwelashweni kwamanzi. inqubo Ebizwa ngokuthi i-AOP), lo mkhiqizo usebenzisa i-UV nano photocatalysis, ubuchwepheshe be-ozone, ubuchwepheshe be-oxidation obuthuthukisiwe ukuze bakhe ama-hydroxyl radicals (OH radicals) endaweni ekhethekile yokusabela, futhi usebenzise ama-hydroxyl radicals ukuze uthole i-oxidation ephumelelayo nethuthukisiwe yezinto eziphilayo emanzini.Futhi ukubola kahle nangempumelelo izinto eziphilayo, amagciwane, amagciwane, ubuthi be-sulfide kanye ne-phosphide emanzini, ukuze kuhlangatshezwane nezidingo zokuqeda iphunga, ukubulala amagciwane, inzalo nokuhlanzwa kwamanzi.Izinga lamanzi alungisiwe liyahlangabezana namazinga afanele kazwelonke.Imikhiqizo ye-AOP inqoba izinkinga zendlela eyodwa yokuhlanza amanzi, futhi izuza umusa wemakethe nabasebenzisi ngezinzuzo zayo eziyingqayizivele zenhlanganisela yobuchwepheshe.
Izici nezinzuzo zemishini yokuhlanza amanzi ye-AOP
Imishini ye-AOP yokuhlanza amanzi iyinhlanganisela ehlanganisa uhlelo lwe-nano-photocatalytic, uhlelo lokukhiqiza umoya-mpilo, uhlelo lwe-ozone, uhlelo lwesiqandisi, uhlelo lokujikeleza kwangaphakathi, uhlelo olusebenzayo lokuhlanganisa amanzi esitimu kanye nohlelo lokulawula oluhlakaniphile.
Kulula ukufaka nokugcina indawo yaphansi.
Ukukhiqizwa okuphezulu kwe-ozone ngokusebenza kahle nokugxila okuphezulu, ukugxila kwe-ozone kukhulu kuno-120mg/L.
Ukuxuba okusebenzayo, amabhamuza weleveli ye-micron, ukuncibilika okuphezulu, i-solute diffusion coefficient kanye nomthamo omkhulu wesitoreji wesigaba esihlakaziwe.
Ubuchwepheshe obukhethekile be-ultraviolet obunamandla, isizukulwane esisheshayo sama-hydroxyl radicals.
I-Nano catalysis esebenzayo, ibola futhi i-oxidize indaba ephilayo khona manjalo.
Ukusabela kuyashesha, kuyasebenza, futhi akukhethi.Amanzi ahlanzekile abona ukukhishwa kwe-oxidation ngokushesha kwezinto eziphilayo ngesikhathi sokungena nokuphuma kumpahla yokusebenza, futhi i-COD yamanzi angcolile ifinyelela izinga elisha lezinga lokuqala lokuphuma kwamanzi noma isidingo sokuphinda kusetshenziswe amanzi.
Ingonakalisa ngokuphelele izinto eziphilayo zibe yi-carbon dioxide namanzi ngaphandle kokungcoliswa kwesibili.
Ukwandisa ngempumelelo isivinini sokudlulisela kanye nesikhathi sokuthintana ne-ozone emanzini ukuze kuthuthukiswe ukusebenza kahle kwe-ozone, ukonga umthamo we-ozone nesikhathi se-oxidation, ngaleyo ndlela konge kakhulu ukutshalwa kwezimali kwemishini ye-ozone kanye nezindleko zokusebenza.
Khulisa isivinini sokuphendula, futhi ube nezici zomjikelezo omude wokushintsha kanye nevolumu encane yokugcwalisa, engasebenza ngempumelelo Khulisa izinga lokusebenzisa i-ozone ngaphezu kuka-15%
Isistimu yokusabela nayo ineminye imisebenzi eyisizayo njengokuvala inzalo, ukunqanda ukukala, ukukhipha umbala, ukususwa kwe-COD, njll.
Isimiso sobuchwepheshe sesistimu yokuhlanza amanzi ye-AOP
Isinyathelo sokuqala, khiqiza ama-hydroxyl radicals.
Imishini yokuhlanza amanzi ye-AOP yamukela ubuchwepheshe obuthuthukisiwe be-oxidation bamazwe ngamazwe, umthombo othile wokukhanya ujabulisa izinto ze-photocatalytic, futhi uhlanganisa i-ozone oxidation ethuthukisiwe kanye nobuchwepheshe bokuhlanganisa obusebenzayo ukuze kukhiqizwe ama-hydroxyl radicals anezici ze-oxidizing ezinamandla kakhulu.
Isinyathelo sesibili, i-oxidized ngokuphelele futhi yabola yaba yi-CO2 ne-H2O
Ama-Hydroxyl radicals abhubhisa ngokuqondile ulwelwesi lwamangqamuzana, asheshe abhubhise izicubu zamangqamuzana futhi asheshe abole amagciwane, amagciwane, ama-microorganisms kanye nezinto eziphilayo zibe yi-CO2 ne-H2O emanzini, ukuze amangqamuzana e-microbial alahlekelwe isisekelo sokuvuka nokukhiqizwa kabusha ukuze afeze injongo yokubola okuphelele. amagciwane, amagciwane kanye nama-bacteria.
Ukusetshenziswa kwemishini yokuhlanza amanzi ye-AOP
Imishini ye-AOP yokuhlanza amanzi isebenzisa i-UV photocatalysis, i-ozone, ubuchwepheshe obuthuthukisiwe be-oxidation.Ngokusho kwezicelo zemboni, imikhiqizo ithuthukise imishini yokuhlanza amanzi okuphuza ye-AOP, imishini yokuhlanza amanzi echibini lokubhukuda ye-AOP, okokuhlanza umfula i-AOP (amanzi amnyama nanukayo) okokuhlanza, kanye nemishini yokuhlanza amanzi e-AOP ejikelezayo, imishini yokuhlanza amanzi angcolile ye-AOP, i-AOP aquaculture. imishini yokuhlanza.
