Hauv kev kho dej kev lag luam, ferrous sulfate tsuas yog siv los ua flocculant nrog zoo flocculation nyhuv; Nws muaj cov peev xwm zoo decolorization; Nws tseem muaj cov haujlwm los ntawm kev tshem tawm cov hlau hnyav ions, roj, phosphorus thiab kom tsis muaj menyuam. Tshwj xeeb, ferrous sulfate muaj qhov pom tseeb ntawm decolorization thiab COD tshem tawm ntawm luam ntawv thiab dyeing dej khib nyiab, ferrite coprecipitation ntawm electroplating cov dej khib nyiab, thiab lwm yam, thiab ferrous sulfate yog pheej yig, yog li nws tsim nyog ntawm thawj qhov kev xaiv rau luam ntawv thiab dyeing, electroplating thiab lwm yam dej khib nyiab. kev kho mob. Thaum qhov ua tau zoo ntawm cov dej ua kom tsis zoo yog qhov tsis zoo lossis qhov siab ntawm qhov sib txawv ntawm cov dej ib puag ncig siab, cov txheej txheem dej tshuaj ib txwm ua ntxiv rau ob qho tshuaj thiab kua qaub los tswj hwm tus nqi pH thiab alkalinity ntawm cov dej circulating thiab txo qhov muaj feem cuam tshuam Cov. Txawm tias cov dej tsis zoo npaum li cas los xij, tsis hais txog cov lim dej loj npaum li cas, lub kaw lus xa dej mus rau hauv lub cev tsis ntxiv cov kua qaub, tab sis muaj cov txiaj ntsig kho tau zoo.
Ferrous sulfate precipitant: nws tuaj yeem tsim cov precipitates nrog sulfides thiab phosphates kom tshem tawm sulfides thiab phosphates. Piv txwv: ferrous sulfate yog siv los kho cov dej sulfur uas muaj cov dej khib nyiab los ntawm luam ntawv thiab cov nroj tsuag zas xim.
Ferrous sulfate thawj tus neeg sawv cev: ferrous sulfate yog tus muaj zog txo tus neeg sawv cev, uas tuaj yeem txo hexavalent chromium los ntawm chromium wastewater muaj cov dej kom trivalent chromium, tsis txhob kim sodium sulfite, sodium bisulfite, sulfur dioxide, thiab lwm yam Cov qauv hluav taws xob muaj qhov zoo ntawm tsis muaj tshuaj lom carcinogenic stimulating chlorine lub cev (feem ntau yog cov leej faj sulfide) thiab tus nqi tsawg.
Siv raws li Fenton reagent. Cov txheej txheem Fenton yog ib hom kev ua haujlwm ntawm cov dej khib nyiab, uas siv cov khoom siv ferrous sulfate ua catalyst thiab hydrogen peroxide (tseem hu ua hydrogen peroxide) rau kev tiv thaiv oxidation. Fenton reagent tuaj yeem ua tiav los tsim cov hydroxyl radicals nrog kev tiv thaiv muaj zog, uas tuaj yeem rhuav tshem thiab rhuav tshem nrog cov qauv ntawm cov kab mob tsis haum rau hauv cov dej tsis huv, kom ua tiav lub hom phiaj ntawm cov pa paug.
Thaum siv cov tshuaj ferrous sulfate, feem ntau yog npaj rau 10% - 25% aqueous tov thiab yaj tag nrho. Tom qab ntawd nws tau muab tso rau hauv pem hauv ntej ntawm lub hauv paus dej hauv cov txheej txheem pov tseg thaum kho cov dej khib nyiab.
Ferrous sulfate yog siv rau kev kho dej phwj tuaj. Txoj kev twg yuav tsum siv los ntxiv thiab nws yooj yim los txo kev siv dag zog? Nyob ntawm qhov xwm txheej thiab kev kho mob muaj peev xwm ntawm cov dej phwj tuaj, muaj cov txheej txheem sib txawv thiab cov txheej txheem tshuaj sib txawv. Raws li kev paub dhau los ntawm kev siv tshuaj tua dej, cia' s qhia cov teeb meem sib thooj hauv qab no. Hauv 50000 / T Lub nroog pov tseg dej kho cov nroj tsuag, cov txheej txheem kev kho yog pov, ferrous sulfate dosing txuas ntxiv muab faib los ntawm ob lub tso tsheb hlau luam, thiab cov twj tso kua mis metering ntxiv nrog ferric oxide hauv kev kho dej tom qab. 30000 / T luam ntawv thiab dyeing dej khib nyiab kho tsob nroj.
