Munguva pfupi yapfuura, chirongwa chinotungamirwa neNanchang University, icho chinobatanidza kushanda uye girinhi kusimudzira kweion adsorption.rare pasizviwanikwa zvine tekinoroji yekudzoreredza tekinoroji, zvakapasa kuongororwa kwekuita kwakadzama nezvibodzwa zvepamusoro.Kubudirira kubudirira kweiyi tekinoroji yezvicherwa yakawana mhedzisiro yakakosha mukuvandudza isingawanzo kudzoreredza pasi uye nekucherwa kwegirinhi kwakanaka, kana kuongorora nzira nyowani yekushandiswa kwakanaka uye kwakasvibira kwezviwanikwa zvepasi zvisingawanzo muChina.
Kubvisa mareagents kubva mumarara uye kuagadzira patsva
Ion adsorptionrare pasichinhu chakasarudzika muChina.Nekudaro, iyo iripo ion adsorptionrare pasitekinoroji yemigodhi inorambidza kuchera uye kushandiswa kweion adsorptionrare pasizviwanikwa muChina.Muchirevo chechinyorwa chino, zvino kukurumidza kugadzira chizvarwa chitsva chehunyanzvi uye tekinoroji yekuchera migodhi.Iyo yakabatanidzwa tekinoroji yekubudirira uye yakasvibira kukura uye ecological kudzoreredza kweion adsorbedrare pasizviwanikwa zvabuda.Yayo synergistic coupling, aluminium magnesium cycling, kutendeuka kwemarara, uye inoshanda uye yakasvibira maitiro inopa mazano matsva ekuvandudza ion adsorbed isingawanzo zviwanikwa zvepasi.
Kubudirira kweion adsorbedrare earthsine nhoroondo yeanopfuura makore makumi mana, uye maitiro ekuvandudza nekuvandudza tekinoroji yekuvandudza ion adsorbed.rare earthsyakagara iri dambudziko kune vatsvakurudzi vepasi vasingawanzoitiki.Mukutanga kwaGumiguru, mutori wenhau akasangana naProfessor Li Yongxiu kubva kuChikoro cheChemistry uye Chemical Engineering paNanchang University.Muhofisi yake, "mepu yekugovera yepasi isingawanzo muChina" inonakidza.Li Yongxiu akataura kuti masainzi ekutsvagisa zvikamu, matekinoroji, uye matarenda pamepu yekugovera akabatana setiweki, ine zvisingaverengeki kubatanidza pakati peumwe neumwe.
Iyo yakabatanidzwa tekinoroji purojekiti yekubudirira kwegirinhi uye kudzoreredza ecological yeion adsorption mhando isingawanzo pasi zviwanikwa yakatungamirwa neNanchang University, yakabatanidzwa pamwe neJiangxi University of Technology, Changchun Institute of Applied Chemistry yeChinese Academy yeSainzi uye mamwe gumi mayuniti, aine Li Yongxiu. semutungamiri weprojekiti.
Kwemakore akawanda, kusvibiswa kweammonia nitrogen kunokonzerwa neammonium sulfate leaching uye kukukurwa kwevhu kunokonzerwa ne-in-situ leaching zvakakanganisa zvakanyanya nharaunda yenzvimbo dzemigodhi.Kunyangwe iyo ichangobva kutangwa leaching maitiro e calcium magnesium chloride uye magnesium sulfate inogona kugadzirisa dambudziko rekusvibiswa kweammonia nitrogen, kushanda kweLeaching hakuna kukwana, uye kushandiswa chaiko kwemigodhi kwakakwira, kunyanya eutrophication yemvura inokonzerwa nemagnesium sulfate zvakare yakakomba. .
Naizvozvo, isu takagadzira inoshanda yakasvibira leaching maitiro uye tekinoroji yekudzokorora tekinoroji tichishandisa aluminiyamu munyu sechizvarwa chitsva leaching reagent."Li Yongxiu akatsanangura kuti tekinoroji iyi inotanga kupaza nekunzwisisa kwechinyakare, ichibva kune yakapusa ion yekutsinhana dzidziso kuenda kune leaching masisitimu akabatanidzwa akabatanidzwa neion hydration uye anion coordination adsorption mune yakapetwa kaviri modhi.
Kusiyana nekare, isu takasarudza inoshanda leaching system uye nzira yekugadzira tichishandisa aruminiyamu munyu sechizvarwa chitsva leaching reagent, "akadaro Li Yongxiu. Aya masisitimu uye nzira dzinosanganisira synergistic leaching system yealuminium munyu uye yakaderera-mutengo inorganic munyu, a yakarongwa leaching process ye calcium magnesium munyu uye aruminiyamu munyu, uye yakarongwa leaching process ye citrate uye yakaderera yekuisa inorganic munyu.
Izvo zvakakosha kucherechedza kuti iyo aluminium munyu uye calcium magnesium munyu yataurwa pamusoro inotorwa uye inodzokororwa kubva mumarara akasara emarara ekugadzirwa kwemigodhi.Kuti izvi zviitike, timu yakagadzira tekinoroji nyowani yekupfumisa uye yekuparadzanisa iyo inokwanisa kuwana kupatsanurwa uye kudzokororwa kweasingawanzo pasi ion kubva kualuminium uye mamwe maion aripo pamwe chete nekunaya, kudhirowa, uye membrane kupatsanura tekinoroji.Isu tinoshandura tsvina yakasimba kubva kune hydrolyzed aluminium slag kuita inoshanda leaching reagents yekugadzira migodhi, kuwana kudzokororwa kwezvinhu zvinosvibisa uye kudzikisa zvakanyanya kushandiswa kwe reagent uye kugadzirwa kunosvibisa."Li Yongxiu akataura kuti nehunyanzvi hwekuparadzanisa tekinoroji, iyo yakambovhiringikarare pasiuye aluminium inogonawo kubatwa sevaenzi.
Nenzira iyi, iyo aluminium yemukati yerare earthsinogona kudzorwa pasi pechiuru chimwe, ichiisa hwaro hwekuwana kuchena kwepamusororare pasikupatsanurwa uye kugadzirwa kwakachena pasina marara eradioactive.
Kubatanidzwa kwe "mining leaching repair" kunowedzera girini kune isingawanzo kuchera pasi
Kubva kuNanchang kuenda kuGanzhou, kubva pazvimbambaira zvepasi zvisingawanzo kunyunguduka nekuparadzanisa mabhizinesi... Li Yongxiu haachayeuki nhamba yenguva dzaakafamba.Kune nzendo dzakawanda dzekudzoka nekudzoka mugore, handizivi kuti ngani.Nekuda kwerare pasiindasitiri, Li Yongxiu akatungamira timu yake kuti igare ichiedza nekuvandudza nzira itsva yekubatsira kusimudzira kwemhando yepamusoro yeindastiri yepasi isingawanzo.
Kuitwa kwechinangwa chenyika che "dual carbon" kwaisa mberi zvinodiwa zvitsva zvekuvandudza nharaunda nekudzivirira kusvibiswa kwezvakatipoteredza, ukuwo kuunza mikana mitsva kuindasitiri isingawanzo indasitiri.
Maitiro ekuwana girini mune isingawanzo kugadzirwa kwepasi uye kubatanidzwa kwe "migodhi leaching kugadzirisa" ndeimwe pfungwa itsva.
Mhedzisiro yeiyi innovation ndeye kushandisa seepage kufanotaura uye nzira dzekudzora kune vaviri kuongorora uye leaching tekinoroji, pamwe neleaching uye kudzoreredza ecological, kuita izvi."Li Yongxiu akati chinhu chakakosha cheiyo ion adsorption type deposits ndiko kusafanana kwavo. Naizvozvo, in-situ leaching tekinoroji yekuchera migodhi inoshaya dhata pamusoro peasingawanzo kugovera pasi uye geological uye hydrological mamiriro haagoneke. Kuti izvi zviitike, boka rekutsvagisa richaita. kukwidziridza mabhenefiti ehunyanzvi eJiangxi University of Technology, Nanchang University, uye Wuhan University mune seepage kufanotaura uye maitiro ekugadzirisa.
Iyo yakasvibirira yekubvisa maitiro eion adsorption mhandorare pasiore haifanire kungofunga zvakakwana kushanda kwemigodhi, kukanganisa kwezvakatipoteredza, kunaka kwechigadzirwa, uye mutengo wekugadzira, asi zvakare kusanganisa zvizere chimiro che geological yemugodhi, leaching solution seepage, uye ecological restoration tekinoroji kukwirisa dhizaini yeinjiniya."Li Yongxiu akatsanangura kuti kuitira kudzivirira kurasikirwa kusiri kurongeka kwekugadzirisa mhinduro uye kuwana kubatanidzwa kwemigodhi, leaching, uye kugadzirisa.
Panyaya yenzira dze ore leaching, isu tinosimudzira kuona kuti totora in-situ leaching kana murwi leaching zvichibva pane data rekuongorora rekugadzira, kana musanganiswa weorganic wenzira mbiri idzi."Li Yongxiu akataura kuti maererano nehunyanzvi hwekugadzira mirwi, boka rekutsvagisa rakagadzira tekinoroji inodzoreka inoonekwa nekukura mirwi kutsiva nzira yekare yakakura-yakakura yekubvisa murwi panguva imwe chete. Izvi zvinobatsira pakuzadzisa kubatanidzwa kwemigodhi. , leaching, uye kugadzirisa, kubvisa kukukurwa kwevhu uye kudonha kwevhu panguva yeleaching process uye inotevera tailings.
Li Yongxiu akaudza vatori venhau kuti chirongwa ichi chinotarisa pazvinhu zvakakosha senge yakaderera zviwanikwa zvekudzoreredza uye yakakosha kukanganisa kwezvakatipoteredza mumhando yeion.rare pasikudhirowa nzira.Iyo yakakosha uye tekinoroji yekutsvagisa nekusimudzira basa rekuita uye rakasvibira ion adsorption mhandorare pasikudhirowa kwakaitwa zvine hurongwa, uye nhevedzano yebudiriro yezvitsva yakawanwa.
Tekinoroji innovation uye kufambira mberi kucharamba kuchiwedzera 'kusvibira' mukusimudzira kweChinarare pasiindasitiri, "akadaro Li Yongxiu. Chirongwa ichi chakaita budiriro itsva mudzidziso yekutanga, kusimudzira tekinoroji, kuratidza mashandisirwo, uye zvimwe zvinhu zvikuru. pasi zviwanikwa, uye kusimudzira kusimudzira kwemhando yepamusoro yervari pasiindasitiri.
