Kushandiswa kweSodium sulfide muElectroplating Wastewater Treatment

ziviso

Indasitiri ye electroplating inoita basa rakakosha muindasitiri yemazuva ano. Maturusi mazhinji muhupenyu hwedu hwemazuva ese akaiswa electroplated, izvo zvisingango wedzera kutaridzika kwavo asi zvinonyatso kunonoka kuita ngura nezvimwe zvinhu. Indasitiri yeElectroplating inoratidzira maitiro akasiyana ekugadzira, zvichikonzera mhando dzakasiyana dzekubuda kwetsvina. Izvi zvinosanganisira acid uye alkali pre-treatment wastewater, cyanide-ine mvura yakasviba kubva kucyanide copper plating, mvura ine tsvina ine mhangura, nickel ine tsvina ine tsvina, chromium-ine tsvina ine chromium, nezvimwe. heavy metal wastewaters. Kurapa idzi tsvina, iyo makemikari agent sodium sulfide kazhinji inoshandiswa. Ichi chinyorwa chichaongorora kushanda kwe sodium sulfide mukurapa electroplating wastewater.

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.

Kune yemahara heavy metal wastewater, sodium sulfide inogona kuwedzerwa zvakananga kurapwa. Nekudaro, kune yakaoma heavy metal wastewater, pre-kurapa kuputsa yakaoma inodiwa. Sodium sulfide inoita hydrolyze uye inopindirana nemvura yakaoma yesimbi inorema kuumba sulfide inonaya ine yakaderera solubility. Aya sulfide precipitates haasi nyore kunyungudika kunyangwe pasi pemamiriro ane acidic. Naizvozvo, kushandisa sodium sulfide kurapa yakaoma heavy metal tsvina ine zvakanakira mutengo 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.
