Pakati pemaindasitiri ekuchenesa mvura yetsvina, kudhinda uye kudhaya tsvina yemvura ndiyo imwe yemvura yakaoma-kubvisa.Iyo ine yakaoma kuumbwa, yakakwira chroma kukosha, yakakwira concentration, uye yakaoma kudzikisa.Ndiyo imwe yetsvina yakakomba uye yakaoma-kuchenesa yemumaindasitiri inosvibisa nharaunda.Kubviswa kwechroma kwakatonyanya kuoma pakati pematambudziko.
Pakati peakawanda ekudhinda nekudhaya nzira dzekuchenesa mvura yetsvina, kushandisa coagulation ndiyo nzira inonyanya kushandiswa mumabhizinesi.Parizvino, iwo akajairwa flocculants anoshandiswa mumachira ekudhinda uye dhayi mabhizinesi munyika yangu ndeye aluminium-based uye iron-based flocculants.Iyo decolorization mhedzisiro haina kunaka, uye kana iyo reactive dhayi ikaita decolorized, pane inenge isina decolorization effect, uye pachange paine maion simbi mumvura inorapwa, iyo ichiri kukuvadza zvakanyanya kumuviri wemunhu uye zvakatenderedza.
Dicyandiamide formaldehyde resin decoloring agent ndeye organic polymer flocculant, quaternary ammonium munyu mhando.Kana ichienzaniswa neyechinyakare yakajairika decolorizing flocculants, ine kukurumidza kuyerera kumhanya, shoma dosage, uye inokanganiswa neinogarisana munyu, PH uye Advantages senge kuderera kwekushisa.
Iyo dicyandiamide formaldehyde resin decoloring agent is flocculant inonyanya kushandiswa decolorization uye COD kubvisa.Paunenge uchiishandisa, zvinokurudzirwa kugadzirisa pH kukosha kwemvura yakasviba kuti isarerekera.Ndokumbira utaure nevanyanzvi kune dzakananga nzira dzekushandisa.Zvinoenderana nekudyidzana kwakawanda Feedback kubva kune vanodhinda uye vanogadzira dhayi ndeyekuti diicyandiamide formaldehyde resin decolorizer ine mhedzisiro yakakosha pakubvisa ruvara rwekudhinda uye kudhaya tsvina yemvura.Iyo chroma yekubvisa rate inogona kusvika kupfuura 96%, uye kubviswa kweCOD kwasvikawo kupfuura 70%.
Organic polymer flocculants yakatanga kushandiswa muma1950s, kunyanya polyacrylamide mvura kurapwa flocculants, uye polyacrylamide inogona kupatsanurwa kuva asiri-ionic, anionic, uye cationic.Muchikamu chino, isu tichanzwisisa iyo acrylamide polymer dicyandiamide formaldehyde resin decolorizing flocculant iyo yakarungwa ne quaternary amine pakati peiyo cationic organic polymer flocculants.
Iyo dicyandiamide formaldehyde resin decolorizing flocculant inotanga kubatwa ne acrylamide uye formaldehyde aqueous solution pasi pemamiriro ealkaline, yozoitwa ne dimethylamine, yozotonhodzwa uye kugadzikiswa ne hydrochloric acid.Chigadzirwa chacho chinomisikidzwa nekubuda uye kusefa kuti uwane quaternized acrylamide monomer.
Iyo dicyandiamide-formaldehyde condensation polymer decolorizing flocculant yakaunzwa muma1990s.Iyo ine yakanakisa yakakosha mhedzisiro yekubvisa ruvara rwedhayi tsvina yemvura.Mukurapa kwepamusoro-ruvara uye yakakwira-yakadzika tsvina, chete polyacrylamide kana polyacrylamide inoshandiswa.Polyaluminium chloride flocculant haigoni kubvisa zvachose pigment, uye mushure mekuwedzera decolorizing flocculant, inogadzirisa kukanganisa kusina kunaka kwakasungirirwa kune mamorekuru edhayi mumvura yakasvibiswa nekupa huwandu hwakawanda hwemacations uye nokudaro inoparadza Pakupedzisira, nhamba huru ye floccules inoumbwa, iyo. inogona kutora mamorekuru edhayi mushure mekufamba uye kudzikamisa, kuitira kuti uwane chinangwa che decolorization.
Maitiro ekushandisa decolorizer:
Nzira yekushandisa decolorizing flocculant yakafanana neye polyacrylamide.Kunyangwe iyo yekutanga iri muchimiro chemvura, inoda kuderedzwa isati yashandiswa.Mugadziri anokurudzira kuti inonatswa ne10% -50%, uye yobva yawedzerwa kumvura yakasvibiswa uye yakanyatsogadziriswa.Gadzira alum maruva.Iyo yeruvara iri mumvura yetsvina ine mavara inopeperetswa uye inodonha kubva mumvura, uye inoshongedzerwa ne sedimentation kana mhepo inoyerera kuti iwane kupatsanurwa.
Mukudhinda nekudhaya, machira nemamwe maindasitiri, kushandiswa kwemvura kwakakura kwazvo uye chiyero chekushandisa zvakare chakaderera.Nokudaro, kutambisa zviwanikwa zvemvura kwakawanda zvikuru.Kana maitiro acho achishandiswa kuita kurapa kwepamusoro uye kudzokororwa kweiyi yakakwira-ruvara uye yakakwira-yakadzika maindasitiri etsvina, Haisi chete inogona kuchengetedza yakawanda yemvura yakachena yemaindasitiri zviwanikwa, asi inogona zvakare kudzikisa zvakananga kubuda kwetsvina yeindasitiri, inova. hukuru uye hunosvika kure kukosha kwekusimudzira kusimukira kwakasimba kwemaindasitiri ekudhinda, kudhaya uye machira.
