Amanzi acocekileyo abalulekile ebomini—kodwa izinto ezininzi ezingcolisayo azinalo unyango oluqhelekileyo. Namhlanje, izinto ezibangela ukungcola ziye zaba ziingongoma ezingadunyiswayo zokunyanga amanzi: zikhawulezisa ukusabela kweekhemikhali, ziqhekeza izinto ezingcolisayo, kwaye ziguqula amanzi angcolisiweyo abe ngamanzi akhuselekileyo—ngaphandle kokusetyenziswa ngokupheleleyo kule nkqubo.
Kwihlabathi liphela, amaziko okucoca amanzi axhomekeke ngakumbi kubuchwepheshe bokutsala amanzi ukususa iintsimbi ezinzima, iikhemikhali ezinobungozi eziphilayo, izibulali-zinambuzane, iidayi, ii-antibiotics, kunye nezinto ezincinci ezingcolisa amanzi ezingenakubanjwa zizihluzi zemveli.
Indlela iiCatalysts ezisebenza ngayo kuNyango lwaManzi
IiCatalysts zisebenza njengezinto ezikhuthaza ukusabela. Zinciphisa amandla afunekayo ukutshabalalisa okanye ukuguqula izinto eziyingozi. Kwiinkqubo ze-oxidation eziphambili (ii-AOP)—ezona ndlela zinamandla zokucoca amanzi—iiCatalysts zisebenza ne-ozone, i-hydrogen peroxide, okanye ukukhanya ukuvelisa iintlobo zeoksijini ezisabela kakhulu. Ezi ntlobo zibola ngokukhawuleza nokuba zingcolisi eziqinileyo, ezingaboliyo zibe ngamanzi angenabungozi kunye ne-carbon dioxide.
Izinto eziqhelekileyo ze-catalyst ziquka i-titanium dioxide (TiO₂), i-alumina esebenzayo, ii-ceramic-supported metals, i-metal-organic frameworks (MOFs), kunye nee-nano-structured metals ezifana ne-iron, i-copper, kunye ne-manganese. Ii-catalysts ezininzi zizinzile kakhulu, zingasetyenziswa kwakhona, kwaye zingabizi kakhulu.
Izicelo eziphambili zeCatalysts kuNyango lwaManzi
Ukuwohloka kwamanzi amdaka emizi-mveliso: IiCatalysts ziqhekeza iidayi ezivela kwimizi-mveliso yelaphu, iikhemikhali ezivela kwimveliso yamayeza, kunye nezinyibilikisi ezivela kwimveliso.
Ukususwa kwee-antibiotics kunye nee-pesticides: I-Catalytic oxidation isusa izinto ezincinci ezingcolisa izityalo ezisongela i-ecosystem kunye nempilo yabantu.
Ukubulala iintsholongwane ngaphandle kweemveliso eziyingozi: Iinkqubo zeCatalytic zibulala iintsholongwane ngokukhuselekileyo, ngokungafaniyo nezinye iindlela zemveli ezenza iintsalela eziyingozi.
Ukususwa kwesinyithi esinzima: Iikhatalyst ezixhaswayo ziguqula iisinyithi ezinobuthi zibe ziimo ezingonakalisiyo okanye zizibambe ukuze zahlulwe lula.
Ukususa i-sulfurization kunye nokususa umbala: IiCatalysts zicoca amanzi ngokukhawuleza ngokususa umbala, ivumba, kunye nezinto ezingcolisayo ezisekelwe kwisalfure.
Kutheni iiCatalysts ziyikamva loNyango lwaManzi
Unyango lwamanzi olusebenzisa i-catalytic lunezibonelelo ezinamandla:
Ukusebenza kakuhle kakhulu nokuba kuphantsi koxinzelelo lwezinto ezingcolisayo
Isantya sokusabela ngokukhawuleza
Ubuchule bokunyanga inkunkuma engaboliyo
Ukusebenza ngendlela enobuhlobo nokusingqongileyo
Ubomi benkonzo ende kunye neendleko zokusebenza eziphantsi
Ngenxa yokunqongophala kwamanzi okwandayo kunye nemithetho engqongqo yokusingqongileyo, izinto ezibangela ukonakala azisafuneki—ziyimfuneko.
Ndijonge phambili
Izazinzulu ziyaqhubeka nokuphuhlisa ii-catalysts ezikrelekrele, eziluhlaza, nezinamandla ngakumbi. Ii-catalysts ezixhaswayo, ii-nano-catalysts, kunye nee-catalysts ezisekelwe kwi-bio zenza unyango lwamanzi lube lucocekile, lube nexabiso eliphantsi, kwaye lube nozinzo ngakumbi.
Kwinjongo yehlabathi yokubonelela ngamanzi okusela akhuselekileyo nokukhusela okusingqongileyo, izinto ezibangela ukonakala azizozinto nje kuphela—zizisombululo eziguqula izinto.
