Ukusetshenziswa kwe-Sodium sulfide ku-Electroplating Wastewater Treatment

Isingeniso

Imboni ye-electroplating idlala indima ebalulekile embonini yesimanje. Amathuluzi amaningi ezimpilweni zethu zansuku zonke afakwe ugesi, angagcini nje ngokuthuthukisa ukubukeka kwawo okuhle kodwa futhi abambezele ngempumelelo ukugqwala nezinye izinkinga. Imboni ye-Electroplating ihlanganisa izinqubo zokukhiqiza ezihlukahlukene, okuholela ezinhlotsheni ezihlukene zokuphuma kwamanzi angcolile. Lokhu kufaka phakathi amanzi angcolile ane-asidi kanye ne-alkali ngaphambi kokwelashwa, i-cyanide-aqukethe amanzi angcolile asuka ku-cyanide copper plating, amanzi angcolile anethusi, amanzi angcolile ane-nickel, amanzi angcolile aqukethe i-chromium, nokunye. amanzi angcolile ensimbi esindayos. Ukwelapha lawa manzi angcolile, i-ejenti yamakhemikhali i-sodium sulfide isetshenziswa kaningi. Lesi sihloko sizohlola ukusebenza kwe-sodium sulfide ekwelapheni electroplating amanzi angcolile.

Izici ze-Sodium sulfide

I-sodium sulfide, eyaziwa nangokuthi i-alkali enukayo, i-soda ephunga, i-alkali ephuzi, i-alkali ebomvu, noma i-sulfide alkali, iyinhlanganisela ye-inorganic. Inesakhiwo esiqinile se-hygroscopic futhi incibilika kakhulu emanzini. Isixazululo saso esinamanzi sine-alkaline enamandla futhi singabangela ukusha lapho sihlangana nesikhumba nezinwele, ngaleyo ndlela igama elithi sulfide alkali.

Izicelo ku-Electroplating Wastewater Treatment

I-sodium sulfide iyasebenza ekwelapheni ukungcola kwensimbi okuhlukahlukene emanzini angcolile e-electroplating. Ingakwazi ukuphatha kuphela ithusi emanzini angcolile e-electroplating kodwa nezinto ezingcolisayo njenge-chromium, i-zinc, i-lead, i-nickel, ne-cyanide. Lapho usebenzisana namanzi angcolile ekhopha ayinkimbinkimbi, indlela evamile iwukwengeza i-ferrous sulfate noma ezinye izinto ezinciphisayo ngaphansi kwezimo ezine-asidi ukuphula inkimbinkimbi. Bese, lungisa i-pH ku-alkaline bese wengeza i-sodium sulfide. Le nqubo inganciphisa inani le-sodium sulfide esetshenzisiwe futhi ivimbele ukwakheka nokukhululwa kwegesi ye-hydrogen sulfide ngaphansi kwezimo ezine-acidic.

Ngamanzi angcolile ensimbi asindayo mahhala, i-sodium sulfide ingafakwa ngokuqondile ukuze iphathwe. Kodwa-ke, emanzini angcolile ensimbi asindayo, ukwelashwa kwangaphambilini ukuphula inkimbinkimbi kuyadingeka. I-sodium sulfide i-hydrolyzes futhi ihlangane namanzi angcolile ensimbi esindayo ukuze akheke i-sulfide iyancipha ne-solubility ephansi kakhulu. Lawa ma-sulfide precipitates awancibiliki kalula ngisho nangaphansi kwezimo ezine-asidi. Ngakho-ke, ukusebenzisa i-sodium sulfide ukwelapha amanzi angcolile ensimbi esindayo kunezinzuzo zezindleko eziphansi nokuzinza okuhle.

Ukucatshangelwa ekusetshenzisweni kwe-Sodium sulfide

Enye yezinkinga ezivamile ekusebenziseni i-sodium sulfide umthamo. Uma umthamo uphansi kakhulu, umphumela wokukhipha ithusi awugculisi. Uma umthamo uphakeme kakhulu, ungawenza ube mnyama umzimba wamanzi futhi ukhulise i-COD ngezinga elithile, ungcolise amanzi. Ukuze ubhekane nalokhu, ngaphambi kokusebenzisa i-sodium sulfide, kuyadingeka ukulungisa inani le-pH lamanzi libe ngu-9. Ukwengeza, ukwenza ukuhlolwa kwe-beaker kusengaphambili ukuze kunqunywe umthamo ofanele kungasiza ekugwemeni imiphumela emibi yokwelapha noma ukwanda kokuqukethwe kwe-COD emanzini.

Isiphetho

I-sodium sulfide inemiphumela emihle yokwelapha emanzini angcolile ensimbi esindayo avela ezimbonini ezihlukahlukene ezifana namabhodi wesekethe aphrintiwe, ukuncibilikisa insimbi, i-electroplating, kanye nokudaya. Kodwa-ke, lapho siwasebenzisa ukwelapha amanzi angcolile e-electroplating, sidinga ukunaka umthamo kanye nenqubo yokwelapha ukuze sikhulise izinzuzo zayo ekwelapheni amanzi angcolile kuyilapho sinciphisa imithelela engemihle engaba khona. Ngokulawula ngokucophelela lezi zici, i-sodium sulfide ingaba ithuluzi elibalulekile ekwelapheni okusebenzayo kwamanzi angcolile e-electroplating, okunomthelela ekuvikelweni kwemvelo kanye nentuthuko eqhubekayo embonini ye-electroplating.
