Udaka olubomvu luyizinhlayiyana ezinhle kakhulu udoti oqinile we-alkaline okhiqizwa inqubo yokukhiqiza i-alumina ne-bauxite njengempahla eluhlaza. Ngethani ngalinye le-alumina ekhiqizwayo, cishe amathani angu-0,8 kuya kwangu-1,5 odaka olubomvu akhiqizwa. Isitoreji esikhulu sodaka olubomvu akugcini nje ngokuthatha umhlaba nokumosha izinsiza, kodwa futhi kubangela kalula ukungcoliswa kwemvelo kanye nezingozi zokuphepha.I-Titanium dioxidei-waste liquid iyi-hydrolysis waste liquid ekhiqizwa lapho i-titanium dioxide ikhiqizwa indlela ye-sulfuric acid. Kuwo wonke amathani e-titanium dioxide akhiqizwayo, amathani ayi-8 kuya kwayi-10 e-asidi engcolile ene-concentration ye-20% kanye nama-50 kuya ku-80 m3 wamanzi angcolile ane-acidic ane-concentration engu-2%. Iqukethe inani elikhulu lezakhi ezibalulekile njenge-titanium, i-aluminium, insimbi, i-scandium, ne-sulfuric acid. Ukukhishwa okuqondile akugcini nje ngokungcolisa kakhulu imvelo, kodwa futhi kubangela ukulahlekelwa okukhulu kwezomnotho.
Udaka olubomvu luwuketshezi oluqinile lwe-alkaline, kanti uketshezi lwe-titanium dioxide luwuketshezi olune-asidi. Ngemva kokunciphisa i-asidi ne-alkali yakho kokubili, izakhi ezibalulekile zigaywa kabusha ngokuphelele futhi zisetshenziswe, ezingagcini nje ngokulondoloza izindleko zokukhiqiza, kodwa futhi zithuthukise izinga lezinto ezibalulekile kumfucumfucu noma uketshezi olulahlwayo, futhi kulungele ngokwengeziwe ukululama okulandelayo. inqubo. Ukugaywa kabusha okuphelele nokusetshenziswa kabusha kwemfucuza yezimboni ezimbili kunokubaluleka okuthile kwemboni, futhii-scandium oxideinenani eliphakeme kanye nezinzuzo ezinhle zezomnotho.
Iphrojekthi yokukhipha i-scandium oxide odakeni olubomvu kanye noketshezi lwemfucuza ye-titanium dioxide ibaluleke kakhulu ekuxazululeni ukungcoliswa kwemvelo nobungozi bokuphepha obubangelwa ukugcinwa kodaka olubomvu kanye nokuchithwa koketshezi lwe-titanium dioxide. Futhi kuwukubonakaliswa okubalulekile kokuqaliswa komqondo wokuthuthukiswa kwesayensi, ukushintsha indlela yokuthuthukiswa komnotho, ukuthuthukisa umnotho oyindilinga, nokwakha umphakathi owonga izinsiza nonobungani bemvelo, futhi kunezinzuzo ezinhle zomphakathi.
