Mekhoa le Litlhokomelo tsa ho Hloekisa Metsi a Sodium Sulfide

Metsi a litšila a sodium sulfide, a hlahisoang ke lits'ebetso tse fapaneng tsa indasteri joalo ka tlhahiso ea lik'hemik'hale, merafo le tlhahiso ea makhasi, a beha likotsi tse kholo tsa tikoloho le bophelo bo botle ka lebaka la chefo ea ona e phahameng le ho bola ha 'mele. Ho phekola metsi ana a litšila ka katleho ho bohlokoa ho fokotsa litlamorao tsa ona tse mpe. Sengoliloeng sena sa blog se tla hlahisa ka botlalo mekhoa ea kalafo le mehato ea bohlokoa ea ho itšireletsa bakeng sa metsi a litšila a sodium sulfide.

1. Mekhoa ea Kalafo

1.1 Pula ea Lik'hemik'hale

Pula ea lik'hemik'hale ke o mong oa mekhoa e sebelisoang haholo ho phekola metsi a litšila a sodium sulfide. Ts'ebetsong ena, letsoai la tšepe le kang tšepe ea tšepe (ferrous sulfate, ferric chloride) kapa letsoai la koporo le kenngoa metsing a litšila. Li-ion tsa sulfide tse ka har'a sodium sulfide li sebetsana le li-ion tsa tšepe, e leng se etsang hore ho thehoe li-insoluble metal sulfide precipitates. Ka mor'a karabelo ea pula, karohano e tiileng-ea metsi e etsoa ka sedimentation kapa filtration, ka katleho ho tlosa sulfide metsing a litšila. Mokhoa ona o batla o le bonolo, o theko e boima, 'me o loketse ho hloekisa metsi a litšila ka sulfide e phahameng.

1.2 Kalafo ea Oxidation

Kalafo ea oxidation e ka fetola sulfide ka metsing a litšila a sodium sulfide hore e be lintho tse seng kotsi haholo. Mekhoa e tloaelehileng ea oxidation e kenyelletsa moea oxidation, chlorine oxidation, le advanced oxidation process (AOPs).

• Ho Oxidation ea Moea : Ha ho na le li-catalyst tse kang manganese dioxide, moea o kenngoa metsing a litšila. Tlas'a maemo a aerobic, sulfide e oxidation ho ba sebabole sa mantlha kapa sulfate. Mokhoa ona o sebetsa hantle ka matla empa o hloka nako e telele ea karabelo 'me o loketse haholoanyane bakeng sa ho phekola metsi a litšila ka mahloriso a tlase a sulfide.

• Ho Oxidation ea Chlorine : Li-oxidant tse nang le chlorine tse kang sodium hypochlorite kapa khase ea chlorine li sebelisoa ho oxidation ea sulfide. Ho oxidation ea chlorine ho potlakile ebile hoa sebetsa, empa ho ka baka kotsi ka lihlahisoa, kahoo ho hlokahala taolo e hlokolosi ea tekanyo.

• Mekhoa e Tsoetseng Pele ea ho Oxidation (AOPs) : Li-AOP, tse kang oxidation ea Fenton le oxidation ea ozone, li hlahisa li-radical tsa hydroxyl tse arabelang haholo. Li-radical tsena li ka oxidation ea sulfide ka potlako 'me tsa e etsa minerale ka botlalo. Mohlala, oxidation ea Fenton e sebelisa hydrogen peroxide le li-ion tsa ferrous ho hlahisa li-radical tsa hydroxyl, tse ka phekolang ka katleho metsi a litšila a sulfide a nang le mahloriso a tlase le a holimo.

1.3 Phekolo ea Likokoana-hloko

Phekolo ea likokoana-hloko e sebelisa likokoana-hloko ho senya sulfide metsing a litšila. Phekolo ea bioloji ea anaerobic, joalo ka tšilo ea lijo ea anaerobic, e ka fetolela sulfide hore e be khase ea hydrogen sulfide tlas'a maemo a anaerobic, e ka tlosoang ka lisebelisoa tsa pokello ea khase. Phekolo ea bioloji ea aerobic e kenyelletsa likokoana-hloko tsa aerobic tse oxidize sulfide ho sulfate e le karolo ea tšebetso ea tsona ea metabolism. Phekolo ea likokoana-hloko e na le botsoalle ba tikoloho ebile e tšoarella, empa e hloka maemo a tsitsitseng a ts'ebetso le nako e batlang e le telele ea phekolo.

2. Litšireletso

2.1 Litlhokomelo tsa polokeho

• Metsi a litšila a sodium sulfide a chefo haholo 'me a ka ntša khase e chefo ea hydrogen sulfide ha a kopana le asiti kapa tlas'a maemo a itseng. Ka hona, nakong ea phekolo, basebetsi ba tlameha ho apara lisebelisoa tse loketseng tsa ho itšireletsa, ho akarelletsa le limaske tsa khase, liatlana, le liaparo tse sireletsang, ho thibela ho hema le ho ama letlalo ka lintho tse chefo.

• Mehaho ea phekolo e lokela ho ba le moea o motle - ho etsa bonnete ba ho tsoa ka nako ea khase ea hydrogen sulfide, ho fokotsa kotsi ea ho bokella le ho phatloha ha khase. Ho lemoha khase khafetsa sebakeng sa kalafo ho bohlokoa ho beha leihlo khatello ea hydrogen sulfide le likhase tse ling tse kotsi.

2.2 Litlhokomelo tsa Ts'ebetso

• Taolo ea Tekanyo ea Reagent : Kalafong ea lik'hemik'hale le ea oxidation , taolo e nepahetseng ea tekanyo ea li-reagent e bohlokoa. Tekanyo e sa lekaneng ea reagent e ka lebisa kalafong e sa fellang, athe tekanyo e feteletseng ha e eketse litšenyehelo tsa kalafo feela empa e ka boela ea baka tšilafalo ea bobeli. Mohlala, kalafong ea lik'hemik'hale, letsoai le feteletseng la tšepe le ka baka boteng ba li-ion tsa tšepe tse setseng metsing a hloekisitsoeng.

• Taolo ea pH : Boleng ba pH ba metsi a litšila bo ama katleho ea kalafo haholo. Puleng ea lik'hemik'hale, li-precipitate tse fapaneng tsa sulfide ea tšepe li thehoa hantle ka har'a mefuta e itseng ea pH. Kalafong ea oxidation, sekhahla sa karabelo ea oxidation le sebopeho sa sehlahisoa le tsona li amana haufi-ufi le boleng ba pH. Ka hona, ho hlokahala tlhokomelo e tsoelang pele le tokiso ea boleng ba pH nakong ea ts'ebetso ea kalafo.

• Tlhokomelo ea Lisebelisoa : Tlhokomelo ea kamehla ea lisebelisoa tsa kalafo, tse kang lipompo, li-mixer le litanka tsa sedimentation, ke ea bohlokoa ho netefatsa ts'ebetso e tloaelehileng ea ts'ebetso ea kalafo. Lisebelisoa tse hanelang mafome li lokela ho sebelisoa bakeng sa lisebelisoa tse amanang le metsi a litšila a sodium sulfide ho eketsa bophelo ba ts'ebeletso ea lisebelisoa.

2.3 Litlhokomelo tsa Tšireletso ea Tikoloho

• Seretse se hlahisoang nakong ea ts'ebetso ea kalafo, haholo-holo ka har'a pula ea lik'hemik'hale, e na le metsi a mangata a tšepe ea sulfide 'me e kanna ea ba le li-reagents tse setseng. Matlakala ana a tlameha ho lahlwa ka nepo ho thibela tshilafalo ya bobedi. E ka romelloa litsing tsa profeshenale tsa kalafo ea litšila tse kotsi bakeng sa ho lahloa ka mokhoa o sireletsehileng.

• Ka mor'a ho phekoloa, boleng ba metsi a litšila bo lokela ho behoa leihlo ka thata ho netefatsa hore a finyella litekanyetso tse loketseng tsa naha le tsa tikoloho ea tikoloho. Haeba boleng ba metsi a litšila bo sa fihlelle litlhoko, ho hlokahala phekolo e eketsehileng kapa tokiso ea tšebetso.

Qetellong, ho phekola metsi a litšila a sodium sulfide ho hloka kutloisiso e felletseng ea mekhoa e fapaneng ea kalafo le ho latela ka tieo litemoso. Ka ho khetha mokhoa o nepahetseng oa phekolo le ho latela mekhoa e nepahetseng ea ts'ebetso, re ka fokotsa ka katleho phello ea tikoloho ea metsi a litšila a sodium sulfide le ho kenya letsoho ho sireletsa tikoloho e tsitsitseng.
