Kutshanje, iprojekthi ekhokelwa yiYunivesithi yaseNanchang, edibanisa uphuhliso olusebenzayo noluluhlaza lwe-ion adsorption.umhlaba onqabileyoizibonelelo ngetekhnoloji yokubuyisela indalo, iphumelele uvavanyo olubanzi lwentsebenzo ngamanqaku aphezulu.Uphuhliso oluyimpumelelo lobu bugcisa bokumbiwa kwemigodi bufumene iziphumo ezibalulekileyo ekuphuculeni izinga lokubuyiswa komhlaba onqabileyo kunye nemigodi eluhlaza esebenzayo, okanye kuphononongwe indlela entsha yokusetyenziswa ngokufanelekileyo kunye nohlaza kobutyebi bomhlaba obunqabileyo eTshayina.
Ukutsalwa kwezixhobo ezivuzayo kwinkunkuma eqinileyo kunye nokuzihlaziya kwakhona
Ion adsorptionumhlaba onqabileyosisixhobo esikhethekileyo eTshayina.Nangona kunjalo, i-ion adsorption ekhoyoumhlaba onqabileyoitekhnoloji yezemigodi ithintela ukumbiwa kunye nokusetyenziswa kwe-ion adsorptionumhlaba onqabileyoizixhobo eTshayina.Kulo mongo, kungxamisekile ukuba kuphuhliswe isizukulwana esitsha sobugcisa bezemigodi obusebenzayo nobuluhlaza.Itekhnoloji edibeneyo yophuhliso olusebenzayo kunye nohlaza kunye nokubuyiselwa kwe-ion adsorbedumhlaba onqabileyoizibonelelo ziye zavela.Ukudibanisa kwayo i-synergistic, ibhayisekile ye-aluminium ye-aluminium, ukuguqulwa kwenkunkuma, kunye neempawu ezisebenzayo kunye nohlaza zibonelela ngemibono emitsha yophuhliso lwe-ion adsorbed ezinqabileyo zomhlaba.
Uphuhliso lwe-ion adsorbedimihlaba enqabileyoinembali engaphezu kwamashumi amane eminyaka, kunye nendlela yokuqalisa nokuphucula itekhnoloji yophuhliso lwe-ion adsorbedimihlaba enqabileyobekusoloko kulucelomngeni kubaphandi bomhlaba obunqabileyo.Ekuqaleni kuka-Oktobha, intatheli yadibana noNjingalwazi uLi Yongxiu ovela kwiSikolo seKhemistry kunye nobuNjineli beMichiza kwiYunivesithi yaseNanchang.Kwiofisi yakhe, "imephu yokusasazwa komhlaba onqabileyo eTshayina" iyamangalisa.U-Li Yongxiu uthe iiyunithi zophando lwesayensi, itekhnoloji, kunye neetalente kwimephu yokuhambisa ziqhagamshelwe njengenethiwekhi, kunye nonxibelelwano olungenakubalwa phakathi komnye nomnye.
Iprojekthi yethekhnoloji edibeneyo yophuhliso olusebenzayo oluluhlaza kunye nokubuyiselwa kwe-ion yohlobo lwe-adsorption enqabileyo yemithombo yomhlaba yayikhokelwa yiYunivesithi yaseNanchang, iphuhliswe ngokudibeneyo yiYunivesithi yeTekhnoloji yeJiangxi, iZiko le-Changchun le-Applied Chemistry ye-Chinese Academy of Sciences kunye nezinye iiyunithi ezilishumi, kunye noLi Yongxiu. njengenkokeli yeprojekthi.
Kangangeminyaka emininzi, ungcoliseko lwe-ammonia nitrogen olubangelwa kukuvuza kwe-ammonium sulfate kunye nokhukuliseko lomhlaba olubangelwe kukuvuza kwe-in-situ kuye kwachaphazela ngokunzulu okusingqongileyo kweendawo zemigodi.Nangona iinkqubo ze-calcium magnesium chloride kunye ne-magnesium sulfate ezisanda kuqaliswa zinokusombulula ingxaki yongcoliseko lwe-ammonia nitrogen, ukusebenza kakuhle kwe-leaching akwanelanga, kwaye ukusetyenziswa kwemigodi kuphezulu, ngakumbi i-eutrophication yamanzi ebangelwa yi-magnesium sulfate nayo inzulu kakhulu. .
Ke ngoko, siye saphuhlisa inkqubo esebenzayo yohlaza kunye netekhnoloji yokuphinda isetyenziswe kusetyenziswa iityuwa ze-aluminium njenge-reagent yesizukulwana esitsha."ULi Yongxiu ucacisile ukuba obu buchwepheshe buqala ngokuqhawuka ukuqonda indlela yemveli, isuka kwithiyori elula yokutshintshiselana nge-ion ukuya kwindlela yokucoca enyanzelwa ngokudibeneyo yi-ion hydration kunye ne-anion coordination adsorption kwimowudi ephindwe kabini.
Ngokungafaniyo nexesha elidlulileyo, siye sakhetha inkqubo esebenzayo yokucoca kunye nendlela yenkqubo ngokusebenzisa iityuwa ze-aluminium njenge-reagent yesizukulwana esitsha, "utshilo uLi Yongxiu. Inkqubo ye-leaching ye-calcium magnesium salts kunye neetyuwa ze-aluminium, kunye nenkqubo ye-leaching ehleliweyo ye-citrate kunye ne-concentration ephantsi yeetyuwa ze-inorganic.
Kuyaphawuleka ukuba iityuwa ze-aluminiyam kunye neetyuwa ze-calcium magnesium ezikhankanywe ngasentla ziyatsalwa kwaye ziphinde zisetyenziswe kumanzi amdaka entsalela yemveliso yemigodi.Ukuza kuthi ga ngoku, iqela liphuhlise itekhnoloji entsha yokutyebisa kunye nokwahlula okunokuthi kufezekiswe ukwahlula kunye nokuphinda kusetyenziswe i-ion zomhlaba ezinqabileyo ezivela kwi-aluminium kunye nezinye ii-ion ezihlala kunye, ezidityaniswe ne-precipitation, i-extraction, kunye ne-membrane yokwahlula iteknoloji.Siguqula inkunkuma eqinileyo isuka kwi-hydrolyzed aluminiyam slag ibe zii-reagents zokuvuza ezisebenzayo kwimveliso yasezimayini, siphumeza ukugaywa kwezinto ezingcolisa umoya kunye nokunciphisa kakhulu ukusetyenziswa kwe-reagent kunye nemveliso engcolisayo."ULi Yongxiu uthe ngetekhnoloji yolwahlulo entsha, eyayikhe yaphixanaumhlaba onqabileyokunye ne-aluminiyam nayo ingaphathwa njengeendwendwe.
Ngale ndlela, umxholo we-aluminium weimihlaba enqabileyoinokulawulwa ngaphantsi kwewaka, ibeka isiseko sokuphumeza ubunyulu obuphezuluumhlaba onqabileyoUkwahlula kunye nemveliso ecocekileyo ngaphandle kwentsalela yenkunkuma ene-radioactive.
Ukudityaniswa "kokulungiswa kwemigodi yemigodi" yongeza uhlaza kwimigodi yomhlaba enqabileyo
Ukusuka eNanchang ukuya eGanzhou, ukusuka kwimigodi yomhlaba enqabileyo ukuya kumashishini anqabileyo okunyibilikisa kunye nokwahlulahlula... U-Li Yongxiu akasakwazi ukukhumbula inani lamaxesha awahambileyo.Zininzi kakhulu iihambo eziya nokubuya enyakeni, andazi ukuba zingaphi.Ngothando lweumhlaba onqabileyokushishino, uLi Yongxiu ukhokele iqela lakhe ukuba lisoloko lizama kwaye livelisa indlela entsha yokunceda uphuhliso olukumgangatho ophezulu kushishino lomhlaba olunqabileyo.
Ukuphunyezwa kwenjongo yesizwe "yekhabhoni emibini" ibeke phambili iimfuno ezintsha zokuphucula imeko yendalo kunye nokuthintela ukungcoliseka kwendalo, ngelixa kuzisa amathuba amatsha kushishino lomhlaba onqabileyo.
Indlela yokufezekisa uhlaza kwinkqubo yokuvelisa umhlaba onqabileyo kunye nokudibanisa "ukulungiswa kwemigodi ye-mining leaching" yenye into entsha.
Undoqo wolu tshintsho kukusebenzisa ingqikelelo ye-seepage kunye neendlela zokulawula ukudibanisa itekhnoloji yokuhlola kunye ne-leaching, kunye ne-leaching kunye nokubuyiselwa kwezinto eziphilayo, ukufezekisa oku."U-Li Yongxiu uthe into ebalulekileyo ye-ion adsorption type deposits kukungafani kwabo. Ngoko ke, iteknoloji ye-mining leaching ye-in-situ ayinayo idatha malunga nokusabalalisa komhlaba onqabileyo kunye neemeko ze-geological kunye ne-hydrological. Ukwandisa inzuzo yobuchwephesha kwiYunivesithi yaseJiangxi yeTekhnoloji, iYunivesithi yaseNanchang, kunye neDyunivesithi yaseWuhan kuqikelelo lwangaphambili kunye nolawulo lwenkqubo.
Inkqubo yotsalo eluhlaza yohlobo lwe-ion adsorptionumhlaba onqabileyointsimbi ekrwada akufunekanga ithathele ingqalelo kuphela ukusebenza kwemigodi, impembelelo yokusingqongileyo, umgangatho wemveliso, kunye neendleko zemveliso, kodwa kwakhona kudityaniswe ngokupheleleyo ubume bejoloji yomgodi, ukuvuza kwesisombululo, kunye nethekhinoloji yokubuyisela indalo ukuze kuphuculwe uyilo lobunjineli."U-Li Yongxiu wachaza ukuba ukuze ugweme ilahleko engacwangciswanga yesisombululo se-leaching kunye nokufezekisa ukudityaniswa kwemigodi, i-leaching, kunye nokulungiswa.
Ngokweendlela zokucoca intsimbi ekrwada, sikhuthaza ukugqiba ukuba ngaba kuthathwe in-situ leaching okanye imfumba yemfumba esekwe kwidatha yokuhlola imveliso, okanye indibaniselwano yendalo yezi ndlela zimbini."U-Li Yongxiu uthe malunga nobuchwepheshe be-heap leaching, iqela lophando liphuhlise ubuchwepheshe obunokulawulwa yimfumba ye-leaching ebonakaliswe ngokukhula kweemfumba ukuze kuthathelwe indawo yendlela yangaphambili ebanzi yemfumba enkulu ye-leaching ngaxeshanye. Oku kuluncedo ekufezekiseni ukudityaniswa kwemigodi , ukuvuza, kunye nokulungiswa, ukuphelisa ukukhukuliseka komhlaba kunye nokudilika komhlaba ngexesha lenkqubo yokukhupha kunye neentsalela ezilandelayo.
U-Li Yongxiu uxelele iintatheli ukuba le projekthi igxile kwimiba ephambili efana nezinga eliphantsi lokubuyiswa kwezixhobo kunye nefuthe elibalulekileyo lokusingqongileyo kuhlobo lwe-ion.umhlaba onqabileyoinkqubo yokutsalwa.Uphando olusisiseko kunye nobuchwepheshe kunye nomsebenzi wophuhliso wohlobo olusebenzayo kunye noluhlaza lwe-adsorption ye-ionumhlaba onqabileyoukutsalwa kuye kwenziwa ngokucwangcisiweyo, kwaye uthotho lweempumelelo ezintsha zifunyenwe.
Ukuveliswa kweteknoloji kunye nenkqubela phambili iya kuqhubeka 'ukongeza uhlaza' kuphuhliso lweChinaumhlaba onqabileyoishishini, "utshilo uLi Yongxiu. Le projekthi yenza impumelelo entsha kwithiyori esisiseko, uphuhliso lwetekhnoloji, umboniso wesicelo, kunye neminye imiba ebalulekileyo. umhlaba, kunye nokukhuthaza uphuhliso olukumgangatho ophezulu we-rzisemhlabeniishishini.
