[Ukwabelana ngobuchwephesha] Ukukhutshwa kwe-scadium oxide ngokuxuba udaka olubomvu kunye ne-titanium dioxide waste acid

Udaka olubomvu lisuntswana elihle kakhulu inkunkuma eqinileyo yealkaline eveliswe kwinkqubo yokuvelisa i-alumina kunye ne-bauxite njengento ekrwada. Ngetoni nganye yealumina eveliswayo, malunga ne-0.8 ukuya kwi-1.5 yeetoni zodaka olubomvu ziveliswa. Ugcino olukhulu lodaka olubomvu aluhlali nje kuphela kumhlaba kunye nemithombo yobutyebi, kodwa lubangela lula ukungcoliseka kwendalo kunye neengozi zokhuseleko.I-Titanium dioxideUlwelo oluyinkunkuma lulwelo lwenkunkuma ye-hydrolysis eveliswa xa i-titanium dioxide iveliswa yindlela ye-sulfuric acid. Ngetoni nganye ye-titanium dioxide eveliswayo, iitoni ezisi-8 ukuya kwezili-10 zenkunkuma yeasidi kunye noxinzelelo lwe-20% kunye ne-50 ukuya kwi-80 m3 yamanzi amdaka aneasidi ene-2% iveliswa. Iqulethe isixa esikhulu sezinto ezixabisekileyo ezifana ne-titanium, i-aluminiyam, isinyithi, i-scandium, kunye ne-asidi ye-sulfuric. Ukukhutshwa okuthe ngqo akungcolisi ngokunzulu imo engqongileyo kuphela, kodwa kubangela ilahleko enkulu kwezoqoqosho.

Udaka olubomvu yinkunkuma eyomeleleyo yealkaline, kwaye ulwelo lwenkunkuma yetitanium dioxide lulwelo oluneasidi. Emva kokunciphisa iasidi kunye nealkali kwezi zimbini, izinto ezixabisekileyo zihlaziywa ngokupheleleyo kwaye zisetyenziswe, ezingenako ukusindisa kuphela iindleko zemveliso, kodwa ziphucule ibakala lezinto ezixabisekileyo kwizinto ezilahlwayo okanye ulwelo olulahlwayo, kwaye lunceda ngakumbi ekubuyiseni okulandelayo. inkqubo. Ukurisayikilishwa okubanzi kunye nokusetyenziswa kwakhona kwenkunkuma emibini yemizi-mveliso kunokubaluleka okuthile kwimizi-mveliso, kunye neiscandium oxideinexabiso eliphezulu kunye neenzuzo ezilungileyo kwezoqoqosho.
Iprojekthi yokutsalwa kwe-scandium oxide eludakeni olubomvu kunye nolwelo lwenkunkuma ye-titanium dioxide ibaluleke kakhulu ekusombululeni ungcoliseko lokusingqongileyo kunye neengozi zokhuseleko ezibangelwa kukugcinwa kodaka olubomvu kunye nokukhutshelwa kwenkunkuma ye-titanium dioxide. Ikwangumfuziselo obalulekileyo wokuphumeza ingqikelelo yophuhliso lwenzululwazi, ukutshintsha imo yophuhliso loqoqosho, ukuphuhlisa uqoqosho olusetyhula, nokwakha uluntu olugcina imithombo yobutyebi nolunobuhlobo kokusingqongileyo, kwaye luneenzuzo ezintle zentlalo.
