Kushandiswa kweSodium sulfide muElectroplating Wastewater Treatment

ziviso

Indasitiri yemagetsi ine basa guru muindasitiri yemazuva ano. Zvishandiso zvakawanda muhupenyu hwedu hwezuva nezuva zvinoputirwa nemagetsi, izvo zvinosimudzira runako rwazvo chete asiwo zvinononotsa ngura nezvimwe zvinetso. Indasitiri yemagetsi ine maitiro akasiyana-siyana ekugadzira, zvichikonzera mhando dzakasiyana dzemvura yakasviba inobuda. Izvi zvinosanganisira mvura yakasviba ine acid nealkali isati yagadziriswa, mvura yakasviba ine cyanide kubva ku cyanide copper plating, mvura yakasviba ine mhangura, mvura yakasviba ine nickel, mvura yakasviba ine chromium, nedzimwe mvura yakasviba ine heavy metal . Kurapa mvura yakasviba iyi, makemikari anoshandiswa sodium sulfide anowanzo shandiswa. Chinyorwa chino chichaongorora kushanda kwe sodium sulfide mukurapa mvura yakasviba inoputirwa nemagetsi.

Zvimiro zveSodium Sulfidi

Sodium sulfide, inozivikanwawo seanonhuwa alkali, soda inonhuwa, yero alkali, tsvuku alkali, kana sulfide alkali, is anorganic compound. Iyo ine yakasimba hygroscopic pfuma uye inonyungudika zvakanyanya mumvura. Mushonga wayo une aqueous wakasimba alkaline uye unogona kukonzera kupisa kana wasangana neganda nebvudzi, saka zita rekuti sulfide alkali.

Zvishandiso muElectroplating Wastewater Treatment

Sodium sulfide inoshanda mukurapa kwakasiyana simbi kusvibisa mu electroplating tsvina yemvura. Haikwanise kubata kwete mhangura chete mumvura ine tsvina ye electroplating asiwo zvinosvibisa zvakaita sechromium, zinc, lead, nickel, uye cyanide. Paunenge uchibata nemvura yakaoma yemhangura yemarara, nzira yakajairika ndeyekuwedzera ferrous sulfate kana zvimwe zvinoderedza zvinhu pasi pemamiriro e acidic kuputsa yakaoma. Zvadaro, gadzirisa pH kune alkaline uye wedzera sodium sulfide. Iyi nzira inogona kuderedza huwandu hwe sodium sulfide inoshandiswa uye kudzivirira kuumbwa uye kusunungurwa kwehydrogen sulfide gasi pasi pemamiriro e acidic.

Kuti mvura ine tsvina yesimbi inorema ishandiswe pasina muripo, sodium sulfide inogona kuwedzerwa zvakananga kuti ishandiswe. Zvisinei, kuti mvura ine tsvina yesimbi inorema ishandiswe, mushonga wekutanga wekupwanya complex unodiwa. Sodium sulfide inonyungudika uye inopindirana nemvura ine tsvina yesimbi inorema kuti igadzire sulfide precipitates ine kunyungudika kwakaderera. Izvi zvinonyungudika zvesulfide hazvinyungudike nyore kunyangwe mumamiriro ezvinhu ane acidic. Saka, kushandisa sodium sulfide kurapa mvura ine tsvina yesimbi inorema kune zvakanakira zvemutengo wakaderera uye kugadzikana kwakanaka.

Mafungiro muKushandiswa kweSodium sulfide

Imwe yezvakajairika nyaya mukushandisa sodium sulfide ndeye dosage. Kana iyo dosage yakanyanya kuderera, iyo mhangura yekubvisa mhedzisiro haina kugutsa. Kana iyo dosage yakawandisa, inogona kusvibisa muviri wemvura uye kuwedzera COD kune imwe nhanho, ichisvibisa mvura. Kuti ugadzirise izvi, usati washandisa sodium sulfide, zvakakosha kugadzirisa pH kukosha kwemvura kusvika kumativi 9. Uyezve, kuitisa bheaker test nguva isati yasvika kuti uone muyero wakakodzera unogona kubatsira kudzivisa migumisiro yakaipa yekurapa kana kuwedzera kweCOD zvinyorwa mumvura.

mhedziso

Sodium sulfide ine maitiro akanaka ekurapa pamvura inorema yesimbi kubva kumaindasitiri akasiyana seakadhindwa edunhu mabhodhi, kunyungudutsa simbi, electroplating, uye dhayi. Nekudaro, kana tichiishandisa kurapa electroplating tsvina yemvura, isu tinofanirwa kutarisisa kuyerwa uye maitiro ekurapa kuti awedzere mabhenefiti ayo mukurapa mvura yetsvina tichideredza zvingangove zvakashata. Nekunyatso kudzora zvinhu izvi, sodium sulfide inogona kuve chishandiso chakakosha mukurapa kunoshanda kwe electroplating tsvina yemvura, ichibatsira mukuchengetedzwa kwezvakatipoteredza uye kusimudzira kwakasimba muindasitiri ye electroplating.
