Tšebeliso ea Sodium Sulfide ka Electroplating Wastewater Treatment

Selelekela

Indasteri ea ho betla ka motlakase e bapala karolo ea bohlokoa indastering ea sejoale-joale. Lisebelisoa tse ngata bophelong ba rona ba letsatsi le letsatsi li betla ka motlakase, e leng se sa ntlafatse ponahalo ea tsona ea botle feela empa hape se liehisa mafome le mathata a mang ka katleho. Indasteri ea ho betla ka motlakase e na le mekhoa e fapaneng ea tlhahiso, e fellang ka mefuta e fapaneng ea ho ntšoa ha metsi a litšila. Tsena li kenyelletsa metsi a litšila a acid le alkali pele ho kalafo, metsi a litšila a nang le cyanide a tsoang ho betla ka koporo ea cyanide, metsi a litšila a nang le koporo, metsi a litšila a nang le nickel, metsi a litšila a nang le chromium, le metsi a mang a litšila a tšepe e boima . Ho phekola metsi ana a litšila, sesebelisoa sa lik'hemik'hale sa sodium sulfide se sebelisoa hangata. Sengoloa sena se tla hlahloba katleho ea sodium sulfide ho phekoleng metsi a litšila a betlang ka motlakase.

Lintho tse molemo tsa sodium sulfide

Sodium sulfide, eo hape e tsejoang e le alkali e nkhang hamonate, soda e monko, alkali e mosehla, alkali e khubelu, kapa alkali ea sulfide, ke motsoako oa inorganic. E na le thepa e matla ea hygroscopic 'me e qhibiliha haholo metsing. Tharollo ea eona ea metsi e na le alkaline e matla 'me e ka baka ho chesa ha e kopana le letlalo le moriri, kahoo e bitsoa sulfide alkali.

Likopo ho Phekolo ea Metsi a Ts'ila ea Electroplating

Sodium sulfide e sebetsa hantle ho phekola litšila tse fapaneng tsa tšepe metsing a litšila a electroplating. Ha e khone ho tšoara koporo feela metsing a litšila a electroplating empa hape le lintho tse silafatsang tse kang chromium, zinki, lead, nickel le cyanide. Ha u sebetsana le metsi a litšila a koporo a rarahaneng, mokhoa o tloaelehileng ke ho eketsa ferrous sulfate kapa lintho tse ling tse fokotsang tlas'a maemo a acidic ho senya ho rarahaneng. Ebe, fetola pH ho alkaline 'me u kenye sodium sulfide. Ts'ebetso ena e ka fokotsa bongata ba sodium sulfide e sebelisoang le ho thibela ho thehoa le ho lokolloa ha khase ea hydrogen sulfide tlas'a maemo a asiti.

Bakeng sa metsi a litšila a tšepe e boima a mahala, sodium sulfide e ka eketsoa ka ho toba bakeng sa kalafo. Leha ho le joalo, bakeng sa metsi a litšila a tšepe e boima a rarahaneng, ho hlokahala phekolo ea pele ho roba motsoako. Sodium sulfide e haella 'me e arabela le metsi a litšila a tšepe e boima a rarahaneng ho etsa li-precipitate tsa sulfide tse nang le ho qhibiliha ho fokolang haholo. Li-precipitate tsena tsa sulfide ha li qhibilihe habonolo esita le tlas'a maemo a asiti. Ka hona, ho sebelisa sodium sulfide ho phekola metsi a litšila a tšepe e boima a rarahaneng ho na le melemo ea litšenyehelo tse tlase le botsitso bo botle.

Litlhaloso mabapi le tšebeliso ea sodium sulfide

E 'ngoe ea mathata a tloaelehileng a ho sebelisa sodium sulfide ke litekanyetso. Haeba tekanyo e le tlase haholo, phello ea ho tlosa koporo ha e khotsofatse. Haeba tekanyo e phahame haholo, e ka fifatsa 'mele oa metsi' me ea eketsa COD ho isa tekanyong e itseng, e silafatsa metsi. Ho sebetsana le sena, pele u sebelisa sodium sulfide, ho hlokahala hore u fetole boleng ba pH ba metsi ho pota 9. Ho phaella moo, ho etsa tlhahlobo ea beaker esale pele ho fumana tekanyo e nepahetseng ho ka thusa ho qoba liphello tse mpe tsa phekolo kapa ho eketseha ha COD content ka metsing.

fihlela qeto e

Sodium sulfide e na le litlamorao tse ntle tsa kalafo ho metsi a litšila a tšepe a boima a tsoang liindastering tse fapaneng joalo ka liboto tsa potoloho tse hatisitsoeng, ho qhibilihisa tšepe, electroplating le ho daea. Leha ho le joalo, ha re e sebelisa ho phekola metsi a litšila a electroplating, re lokela ho ela hloko litekanyetso le ts'ebetso ea phekolo ho eketsa melemo ea eona ea ho hloekisa metsi a litšila ha re ntse re fokotsa liphello tse mpe tse ka bang teng. Ka ho laola lintlha tsena ka hloko, sodium sulfide e ka ba sesebelisoa sa bohlokoa ho phekoloa ka katleho ea metsi a litšila a electroplating, ho kenya letsoho ho sireletsa tikoloho le nts'etsopele e tsitsitseng indastering ea electroplating.
