Basa re calcium chloride mukurapwa kwetsvina

Kutanga, nzira yekuchenesa tsvina inonyanya kusanganisira kurapwa kwepanyama uye kurapwa kwemakemikari.Iyo yemuviri nzira ndeyekushandisa akasiyana mafirita ane akasiyana pore saizi, kushandiswa kweadsorption kana kuvharira nzira, kusvibiswa kuri mumvura kunovharirwa, iyo inonyanya kukosha mune adsorption nzira ndeye adsorption ine activated kabhoni, nzira yekuvhara. kupfuudza mvura nemusefa zvinhu, kuitira kuti huwandu hwakakura hwetsvina husapfuura, uyezve kuwana mvura yakachena.Mukuwedzera, nzira yemuviri inosanganisirawo nzira yekunaya, iyo ndeyokurega tsvina ine chikamu chiduku ichiyangarara pamusoro pemvura kuti iite hove kunze, kana tsvina ine chikamu chikuru chinonaya pasi pepamusoro, uye wozowana.Nzira yemakemikari ndeyekushandisa zvakasiyana-siyana zvemakemikari kushandura tsvina mumvura kuti iite zvinhu zvisinganyanyi kukuvadza muviri wemunhu, kana kusvibiswa kwakanyanyisa, nzira yekurapa makemikari inofanira kushandiswa kwenguva yakareba kuwedzera alum kune mvura, mushure mekuunganidzwa kwetsvina mumvura, ivhu rinova rakakura, unogona kushandisa nzira yekusefa kuti ubvise tsvina.

Calcium chloride, kemikari inowanzoshandiswa mukuchenesa tsvina, inorganic compound iyo iri munyu inoumbwa neklorini uye calcium, inowanzoitika ionic halide.Chloride ions inogona kuchenesa mvura, kuuraya utachiona hunokuvadza, uye kuderedza huturu hwemvura.Calcium ions inogona kutsiva simbi cations iri mumvura, kupatsanura uye kusabvisa muchetura heavy metal ions, uye kubvisa calcium ion precipitation, ine yakanaka disinfection uye kuchenesa maitiro.

Izvi zvinotevera kuunza chaiyo basa re calcium chloride mukurapwa kwetsvina:

1. Calcium chloride yakanyungudutswa mumvura mushure mekunge chloride ion ine simba rekuita sterilization.

2. Calcium ions inogona kutsiva simbi cations mu effluent, kunyanya mutsvina yekuchenesa nzira ine simbi cations.Kuti uderedze kukuvadzwa kwezvinhu zvine muchetura zvakanyanya zvesimbi cations kune chikamu chebiochemical, calcium chloride inoshandiswa mu pretreatment process kubvisa izvi zvine chepfu uye zvinokuvadza zvinhu, izvo zvinoita basa rakakosha.Kana chinhu ichi chikashandiswa muchikamu chemvura, chloride ions inoita basa rebhakitiriya.Calcium ions yakagadzira calcium hydroxide yakanaya uye yakabviswa nekunaya.

3. PH neutralization uye pre-regulation ye acidic sewage pipe network kuwedzera hupenyu hwebasa repombi network.

Yakananga application process: Mushure mekunge mvura yetsvina yaunganidzirwa mutangi rekudzora, mvura yetsvina inosimudzwa kune coagulation tank nepombi inosimudza.Iyo coagulation tank yakakamurwa kuita maviri maitiro ekunonoka kusanganisa uye nekukurumidza kusanganisa, huwandu hwematanho mana ekuita.Mune tangi yekusanganisa inokurumidza, sodium hydroxide inowedzerwa kune dosing pombi kugadzirisa iyo PH yemvura yakasanganiswa mutangi kusvika ku8, uye mvura-soluble polyaluminium chloride uye calcium chloride inowedzerwa panguva imwe chete.Nokuwedzera flocculant polyacrylamide mune inononoka kusanganisa tangi, iyo yakaumbwa karusiyamu chloride zvimedu zvinobatana pamwe chete kuti zvigadzire hombe granular floc;Mushure mekuyerera, iyo inoyerera inoyerera ichipinda mudhangi resedimentation, kuburikidza nekugara kwechisikigo kuti uwane chinangwa chechakasimba-chimvura kuparadzaniswa, iyo supernatant yakapfachukira kubva kumusoro kweiyo sedimentation tangi, ichibva yayerera ichipinda muchipiri coagulation precipitation.Mushure meiyo yechipiri coagulation uye kunaya kwemvura kurapwa, mvura inopfuura nepabhegi sefa uye yakagadziriswa kabhoni sefa ichipinda muasidhi-base neutralization dziva remuridzi mushure mekupfuura kuwanikwa kwepamhepo kweiyo fluoride ions, uye ipapo iyo pH kukosha inogadziriswa uye kuburitswa.Mvura isina kukodzera inoiswa muconditioning tank yobva yagadziriswa.
