Posachedwapa, polojekiti motsogozedwa ndi Nanchang University, amene integrates imayenera ndi wobiriwira chitukuko cha ion adsorption.dziko losowazokhala ndi ukadaulo wobwezeretsa zachilengedwe, zidapambana kuwunika kokwanira kwa magwiridwe antchito ndi zigoli zambiri.Kukula bwino kwaukadaulo wamakono wamigodiwu kwapeza zotulukapo zazikulu pakuwongolera kuchuluka kwa kuchira kwapadziko lapansi komanso migodi yobiriwira yobiriwira, kapena kuwunikira njira yatsopano yogwiritsira ntchito bwino komanso kobiriwira kwazinthu zosowa padziko lapansi ku China.
Kutulutsa ma reagents otulutsa ku zinyalala zolimba ndikuzibwezeretsanso
Ion adsorptiondziko losowandi chida chapadera ku China.Komabe, ion adsorption yomwe ilipodziko losowaukadaulo wa migodi umaletsa migodi ndi kugwiritsa ntchito adsorption ya iondziko losowachuma ku China.M'nkhaniyi, m'pofunika kukhazikitsa mbadwo watsopano wa matekinoloje ogwira mtima komanso obiriwira.Ukadaulo wophatikizika wachitukuko choyenera komanso chobiriwira komanso kubwezeretsa zachilengedwe kwa ion adsorbeddziko losowazida zatulukira.Kulumikizana kwake kogwirizana, kukwera njinga kwa aluminium magnesium, kutembenuka kwa zinyalala, komanso mawonekedwe abwino komanso obiriwira amapereka malingaliro atsopano pakupanga zinthu za ion adsorbed osowa padziko lapansi.
Kukula kwa ion adsorbedmayiko osowaili ndi mbiri yazaka zopitilira makumi anayi, komanso momwe mungapangire ndikusintha ukadaulo wa chitukuko cha ion adsorbedmayiko osowanthawi zonse zakhala zovuta kwa ofufuza osowa padziko lapansi.Kumayambiriro kwa Okutobala, mtolankhaniyo adakumana ndi Pulofesa Li Yongxiu wakusukulu ya Chemistry ndi Chemical Engineering ku Nanchang University.Mu ofesi yake, "mapu ogawa amitundu yosowa ku China" ndiwodabwitsa.Li Yongxiu adati magawo ofufuza asayansi, matekinoloje, ndi maluso omwe ali pamapu ogawa amalumikizidwa ngati netiweki, ndi kulumikizana kosawerengeka pakati pawo.
Integrated teknoloji polojekiti ya imayenera wobiriwira chitukuko ndi kubwezeretsedwa kwa chilengedwe cha ion adsorption mtundu osowa dziko chuma anatsogozedwa ndi Nanchang University, pamodzi kupangidwa ndi Jiangxi University of Technology, Changchun Institute of Applied Chemistry ya Chinese Academy of Sciences ndi mayunitsi ena khumi, ndi Li Yongxiu. monga mtsogoleri wa polojekiti.
Kwa zaka zambiri, kuipitsidwa kwa ammonia nayitrogeni komwe kumachitika chifukwa cha kukhetsa kwa ammonium sulfate komanso kukokoloka kwa nthaka komwe kumadza chifukwa cha in-situ leaching kwakhudza kwambiri chilengedwe cha migodi.Ngakhale posachedwapa anapezerapo leaching njira ya kashiamu magnesium kolorayidi ndi magnesium sulphate angathe kuthetsa vuto la ammonia nayitrogeni kuipitsa, ndi leaching dzuwa sikokwanira, ndi kumwa kwenikweni migodi ndi apamwamba, makamaka eutrophication madzi chifukwa cha magnesium sulfate nawonso kwambiri. .
Chifukwa chake, tapanga njira yabwino yolumikizira yobiriwira komanso ukadaulo wobwezeretsanso zinthu pogwiritsa ntchito mchere wa aluminiyamu ngati m'badwo watsopano wa leaching reagent."Li Yongxiu adalongosola kuti ukadaulo uwu umayamba kusokoneza kumvetsetsa kwamachitidwe achikhalidwe, kuchoka ku lingaliro losavuta losinthira ma ion kupita ku njira yolumikizira yomwe imalumikizidwa ndi ion hydration ndi ma anion coordination adsorption munjira ziwiri zosanjikiza.
Mosiyana ndi m'mbuyomu, tasankha imayenera leaching dongosolo ndi ndondomeko njira ntchito zotayidwa mchere monga m'badwo watsopano leaching reagent, "anati Li Yongxiu. Machitidwe ndi njira monga synergistic leaching dongosolo la zotayidwa mchere ndi otsika mtengo mchere mchere, a adapanga leaching ndondomeko ya calcium magnesium salt ndi aluminiyamu mchere, ndi staged leaching ndondomeko ya citrate ndi otsika ndende mchere mchere.
Ndikoyenera kudziwa kuti mchere wa aluminiyamu ndi mchere wa calcium magnesium womwe watchulidwa pamwambapa umachotsedwa ndikusinthidwanso kuchokera kumadzi otsalira a zinyalala opangira migodi.Kuti izi zitheke, gululi lapanga ukadaulo watsopano wolemeretsa komanso wolekanitsa womwe ungathe kukwaniritsa kulekanitsa ndi kubwezeretsanso ma ion padziko lapansi osowa kuchokera ku aluminiyamu ndi ma ion ena omwe amakhalapo, kuphatikiza ukadaulo wa mpweya, kutulutsa, ndi kulekanitsa kwa membrane.Timatembenuza zinyalala zolimba kuchokera ku hydrolyzed aluminiyamu slag kukhala zopangira zopangira zopangira migodi, kukwaniritsa kukonzanso zowononga zowononga ndikuchepetsa kwambiri kugwiritsa ntchito ma reagent ndi kupanga zoipitsa."Li Yongxiu adanena kuti ndi luso lamakono lolekanitsa, lomwe linasokonezekadziko losowandi aluminiyumu amathanso kuchitidwa ngati alendo.
Mwanjira iyi, zotayidwa za aluminiyamumayiko osowaikhoza kulamuliridwa pansi pa chikwi chimodzi, ndikuyika maziko a kukwaniritsa chiyero chapamwambadziko losowakulekanitsa ndi kupanga ukhondo popanda zotsalira za radioactive.
Kuphatikizana kwa "mining leaching repair" kumawonjezera zobiriwira ku migodi yachilendo yapadziko lapansi
Kuchokera ku Nanchang kupita ku Ganzhou, kuchokera ku migodi yachilendo kupita ku mabizinesi osowa kwambiri osungunula ndi kupatukana... Li Yongxiu satha kukumbukiranso kuchuluka kwa maulendo omwe adayenda.Pali maulendo ambiri obwerera ndi mtsogolo m'chaka, sindikudziwa kuti angati.Ndi chikondi kwadziko losowamakampani, Li Yongxiu adatsogolera gulu lake kuti ayese nthawi zonse ndikupanga njira zatsopano zothandizira chitukuko chapamwamba chamakampani osowa padziko lapansi.
Kukhazikitsidwa kwa cholinga cha dziko la "dual carbon" kwapereka zofunikira zatsopano pakuwongolera chilengedwe komanso kupewa kuipitsidwa kwa chilengedwe, komanso kubweretsa mwayi watsopano kumakampani osowa padziko lapansi.
Momwe mungakwaniritsire zobiriwira pazosowa zapadziko lapansi komanso kuphatikizika kwa "mining leaching kukonza" ndi mfundo ina yatsopano.
Chofunikira pazatsopanozi ndikugwiritsa ntchito kulosera zam'tsogolo ndi njira zowongolera kuti tigwirizane ndi ukadaulo wofufuza ndi leaching, komanso kukonzanso ndi kubwezeretsa zachilengedwe, kuti akwaniritse izi."Li Yongxiu adanena kuti mbali yofunika kwambiri ya ma depositi amtundu wa ion adsorption ndi kusagwirizana kwawo. Choncho, teknoloji ya migodi ya in-situ leaching yopanda chidziwitso pa kugawa kwapadziko lapansi kosowa komanso zochitika za geological ndi hydrological sizotheka. Kuti izi zitheke, gulu lofufuza lidzatha kutengera luso laukadaulo la Jiangxi University of Technology, Nanchang University, ndi Wuhan University pakulosera kowoneka bwino komanso kuwongolera njira.
Njira yotulutsa yobiriwira yamtundu wa ion adsorptiondziko losowaore sayenera kungoganizira mozama momwe migodi ikugwirira ntchito, momwe chilengedwe chimakhudzira, mtundu wazinthu, ndi mtengo wopangira, komanso kuphatikizira bwino momwe mgodiwo ulili, njira yothirira madzi, komanso umisiri wobwezeretsa zachilengedwe kuti akwaniritse kamangidwe ka uinjiniya."Li Yongxiu anafotokoza kuti pofuna kupewa unorganized imfa ya leaching njira ndi kukwaniritsa kuphatikiza migodi, leaching, ndi kukonza.
Pankhani ya njira zochotsera miyala, timalimbikitsa kuti tidziwe ngati titengera in-situ leaching kapena mulu wa leaching potengera zomwe zatulukira, kapena kuphatikiza njira ziwirizi."Li Yongxiu ananena kuti ponena za luso mulu leaching, gulu kafukufuku apanga controllable mulu leaching luso yodziwika ndi milu kukula m'malo m'mbuyomu yaikulu mulu leaching njira ya leaching munthawi yomweyo leaching. Izi zimathandiza kukwaniritsa kusakanikirana kwa migodi. , leaching, ndi kukonza, kuthetsa kukokoloka kwa nthaka ndi kugwa kwa nthaka panthawi ya leaching ndi tailings wotsatira.
Li Yongxiu adauza atolankhani kuti polojekitiyi ikuyang'ana kwambiri zinthu zazikulu monga kuchepa kwa zinthu zomwe zimagwira ntchito komanso kukhudzidwa kwakukulu kwa chilengedwe pamtundu wa ion.dziko losowam'zigawo ndondomeko.Kafukufuku woyambira komanso waukadaulo ndi ntchito yachitukuko yamtundu wabwino komanso wobiriwira wa ion adsorptiondziko losowam'zigawo zachitika mwadongosolo, ndipo mndandanda wa zinthu zatsopano zakwaniritsidwa.
Kusintha kwaukadaulo komanso kupita patsogolo kwaukadaulo kupitilirabe 'kuwonjezera zobiriwira' pakukula kwa Chinadziko losowamakampani, "anatero Li Yongxiu. Pulojekitiyi yapanga zopambana zatsopano mu chiphunzitso choyambirira, chitukuko chaumisiri, chiwonetsero cha ntchito, ndi mbali zina zazikulu. nthaka, ndikulimbikitsa chitukuko chapamwamba cha rndi dzikomafakitale.
