Ukusetyenziswa kweSodium Sulfide kwi-Electroplating Waste Water Treatment

intshayelelo

Ishishini le-electroplating lidlala indima ebalulekileyo kushishino lwanamhlanje. Izixhobo ezininzi kubomi bethu bemihla ngemihla zifakelwe i-electroplated, nto leyo engagcini nje ngokuphucula ubuhle bazo kodwa ikwalibazisa ngempumelelo ukugqwala kunye neminye imiba. Ishishini le-electroplating lineenkqubo ezahlukeneyo zemveliso, nto leyo ekhokelela kwiintlobo ezahlukeneyo zokukhupha amanzi amdaka. Ezi ziquka amanzi amdaka angaphambi konyango lwe-acid kunye ne-alkali, amanzi amdaka aqulethe i-cyanide avela kwi-cyanide copper plating, amanzi amdaka aqulethe i-copper, amanzi amdaka aqulethe i-nickel, amanzi amdaka aqulethe i-chromium, kunye namanye amanzi amdaka anesinyithi esinzima . Ukunyanga la manzi amdaka, i-chemical agent sodium sulfide idla ngokusetyenziswa. Eli nqaku liza kuphonononga ukusebenza kwe-sodium sulfide ekunyangeni amanzi amdaka asebenzisa i-electroplating.

Iipropati zeSodium Sulfidi

I-sodium sulfide, ekwaziwa njenge-alkali enukayo, isoda enukayo, ialkali etyheli, ialkali ebomvu, okanye ialkali yesulfide, yikhompawundi ye-inorganic. Inepropathi eyomeleleyo yehygroscopic kwaye inyibilika kakhulu emanzini. Isisombululo sayo samanzi sinamandla e-alkaline kwaye sinokubangela ukutshisa xa sidibana nolusu kunye neenwele, ngoko ke igama elithi sulfide alkali.

Ukusetyenziswa kunyango lwamanzi amdaka nge-Electroplating

I-sodium sulfide iyasebenza ekunyangeni izingcolisi ezahlukeneyo zesinyithi kumanzi amdaka e-electroplating. Ayinakuphatha kuphela ubhedu kumanzi amdaka e-electroplating kodwa kunye nezinto ezingcolisayo ezinjengechromium, zinc, lead, nickel, kunye necyanide. Xa ujongene namanzi amdaka obhedu obunzima, indlela eqhelekileyo kukongeza i-ferrous sulfate okanye ezinye izinto zokunciphisa phantsi kweemeko ze-acidic ukuphula i-complex. Emva koko, lungisa i-pH kwi-alkaline kwaye ungeze i-sodium sulfide. Le nkqubo inokunciphisa inani le-sodium sulfide esetyenziswayo kwaye ithintele ukubunjwa kunye nokukhululwa kwegesi ye-hydrogen sulfide phantsi kweemeko ze-acidic.

Kwinkunkuma yesinyithi esinzima yasimahla, i-sodium sulfide ingongezwa ngokuthe ngqo ukuze inyangwe. Nangona kunjalo, kwinkunkuma yesinyithi esinzima eyinkimbinkimbi, kufuneka unyango lwangaphambi kokuqhekeza i-complex. I-sodium sulfide iyayinyibilikisa kwaye iphendulane namanzi amdaka esinyithi esinzima ayinkimbinkimbi ukuze yenze ii-sulfide precipitates ezinokunyibilika okuphantsi kakhulu. Ezi precipitates ze-sulfide azinyibiliki lula naphantsi kweemeko ze-asidi. Ke ngoko, ukusebenzisa i-sodium sulfide ukunyanga amanzi amdaka esinyithi esinzima ayinkimbinkimbi kuneengenelo zexabiso eliphantsi kunye nokuzinza okuhle.

Ukuqwalaselwa kokusetyenziswa kweSodium Sulfidi

Omnye wemiba eqhelekileyo ekusebenziseni i-sodium sulfide yidosi. Ukuba i-dosage iphantsi kakhulu, umphumo wokususa ubhedu awunelisi. Ukuba idosi iphezulu kakhulu, inokuwenza mnyama umzimba wamanzi kwaye inyuse iCOD ukuya kwinqanaba elithile, ingcolise amanzi. Ukujongana nale nto, ngaphambi kokusebenzisa i-sodium sulfide, kuyimfuneko ukulungelelanisa ixabiso le-pH lamanzi malunga ne-9. Ukongezelela, ukuqhuba uvavanyo lwe-beaker kwangaphambili ukumisela i-dosage efanelekileyo kunokunceda ukuphepha imiphumo emibi yonyango okanye ukwanda komxholo we-COD emanzini.

isiphelo

I-sodium sulfide ineziphumo ezilungileyo zonyango kumanzi amdaka esinyithi anzima avela kumashishini ahlukeneyo anje ngeebhodi zesekethe eziprintiweyo, ukunyibilikiswa kwesinyithi, i-electroplating, kunye nokudaya. Nangona kunjalo, xa siyisebenzisa ukunyanga amanzi amdaka e-electroplating, kufuneka sinikele ingqalelo kwidosi kunye nenkqubo yonyango ukukhulisa iingenelo zayo ekuphatheni amanzi amdaka ngelixa sinciphisa iimpembelelo ezinokuthi zibe kho. Ngokulawula ngokucophelela ezi zinto, i-sodium sulfide ingaba sisixhobo esibalulekileyo kunyango olusebenzayo lwamanzi amdaka e-electroplating, igalelo ekukhuselweni kwendalo kunye nophuhliso oluzinzileyo kwishishini le-electroplating.
