Nanofiltration membranes inogona kuchengetedza nano-saizi zvinhu, uye mamwe maitiro anosarudza iwo chaiwo mavara ekushandiswa kwemhando ye nanofiltration membranes, iyo inogona kukamurwa kuita zvinotevera zvinhu.
1. Kushandiswa kwe nanofiltration membrane mukurapwa kwemvura yakapfava.
Nekuda kwekuti iwo maion maviri akanyatso kubatwa uye kuderera kwakadzika kunogona kushandiswa pamitengo yemvura yakakwira, kuvava kwacho kunobviswa munyu, izvo zvinotora musika wekuvandudza we sodium application. Kubatsira kwayo kukuru ndeyekuti haina ma microorganisms uye haidi kuvandudzwa. , Inopinda mumvura uye organic matter, nyore, haitore nzvimbo, etc. Uyezve, inenge iri pedyo nenzira maererano nekutsvaga mari uye mutengo, saka pane zvakakodzera uye zvechinyakare organic operation mumunda uyu.
2. Kushandiswa kwe nanofiltration membrane mukuchenesa mvura yekunwa.
Nekuda kwekusara kwekusvibiswa kwemvura, kuyedza kwemhando yezvinhu zvakabatanidzwa kwakaratidza kuti nanofiltration membranes inogona kubvisa zvishoma muchetura kubva-zvigadzirwa, zvakasara zvesora, mishonga yekuuraya zvipembenene, yakasikwa organic zvinhu, zvakasikwa organic zvinhu, mhando yemvura, uye sulfide inogadzirwa mu disinfection process. Munyu uye nitrate, etc. Iyo inewo zvakanakira kunaka kwemvura, kugadzikana, kuderera kwemuyero wemakemikari, diki nyore, kuchengetedza simba, manejimendi uye kugadzirisa, uye zvakanyanya zero kuburitsa. Naizvozvo, nanofiltration membranes inogona kuve yakasarudzika tekinoroji yekucheneswa kwakachena muzana remakore rechi21.
3. Kushandiswa kwe nanofiltration membrane pane munyu uri munzvimbo ine porous.
Mukuvandudza kwekuisa munyu mumvura yepasi, munzvimbo dzinotongwa nekurima, indekisi yemhando yemvura iri kure uye padyo, uye reverse osmosis tekinoroji inogona kushandiswa kuchera munyu nezvimwe zvinhu. Asi nekuda kwekuti mvura yekudzosa chiyero chakanyanya. Panguva imwecheteyo, kurapwa kwe condensate idambudziko zvakare. Kazhinji, ion-exchange nzira inodiwa kurapa tsvina.
Kune rimwe divi, ion exchange resin inosarudza kuchinjanisa divalent uye yakakwirira-valent ions. Kana iyo yepamusoro-yemutengo wemukati mune yekudzikisa mhinduro inowedzera mutengo wekugadzirisa, centralized regeneration ichawedzera mvura yakakura kutanga. Munyu wakanyanya-munyu unobatwa nenanofiltration membrane uye wozobatwa neion exchange nzira, nguva yekurapa inogona kuwedzerwa ne2 kusvika ku3 nguva.
Mushonga wacho une nhamba yakawanda yeinorganic salts. Mushure meiyo sodium ion exchange column, iyo inorganic ion inotsinhaniswa nemakloridi. Panguva ino, iyo nitrate yemukati mumvura inosangana nezvinodiwa zveinorganic munyu. Zvakanakira zvaro ndezvekuti: inogona kupindira nitrate, uye mwero wekudzoreredza mvura wakakwira. Iyi nzira yakashandiswa zvakanyanya muGermany.
4. Kushandiswa kwe nanofiltration membrane mumashizha ekurapa.
Nekuti iyo yakasara ine yakawanda yakawanda yekotoni, iyo inogona kupinda uye kunyura mumwe nemumwe, huni dema nehuni yakakangwa inogadzirwa mukugadzira matanda matema uye pulp yehuni inotorwa ne element uye absorption nzira nekuti zvakawanda organic zvinhu mu peat. vane mhosva dzisina kunaka uye vari nyore kupomerwa zvakanaka. Iyo nanofiltration membrane inoparadzwa panzvimbo yekukonzera kusvibiswa kwakakomba. Semuyenzaniso, nanofiltration membranes anoshandiswa kuchenesa tsvina yemvura inogadzirwa mune alkali yekubvisa nhanho yehuni pulping, iyo ribhoni membrane, biomembrane uye ivhu lignin mumvura inorasa inogona kubatwa, uye monovalent ion ion isingade kubatwa. inogona kufara zvakare kuburikidza ne membrane, The decolorization rate yefirimu inosvika 98%.
5. Kushandiswa kwe nanofiltration membranes muhutano hwepamusoro hwetsvina.
Membrane filtration treatment inzira yakakosha yekuona kudzokororwa kwetsvina. Maitiro ayo makuru anosanganisira flocculation sedimentation, disinfection, uye mamwe maitiro ekurapa. Iyo nzira mushure mekurapa kwe membrane inosanganisirawo kurapwa kwe membrane. Vose vanogona kushandisa mvura yakacheneswa.
Yechitanhatu, iyo nanofiltration membrane ine zvinyoro zvikumbiro mukurapwa.
Muchigadzirwa che electroplating uye alloy kugadzira, mvura yakawanda inowanzocheneswa nekuda kwehuwandu hwemhangura, senge nickel, iron, uye zinc. Yakagadziriswa kuita sediments, kana nanofiltration membrane tekinoroji ikashandiswa, inopfuura 90% yechikamu inogona kudzoserwa kucheneswa, uye kukosha chaiko kunogona kuderedzwa nekagumi kuitira kuti kuderedzwa kugone kushandiswa zvakare.
Pasi pemamiriro akakodzera, nanofiltration membranes inogonawo kuwana kupatsanurwa kwezvinhu zvakasiyana-siyana zvesimbi mumhinduro, zvakadai sekuparadzaniswa kweCd neNi, kutanga kuashandura kuva CdCl2 neNiCl2, uye wobva wawedzera NaCl kuti iite zvinhu zvakabhadharwa uye zvisingabhadhari zvakateerana Zvinhu. Kana huwandu hweNaCl huri 01mol/L kana ruvara rwuripo mune mhinduro, inonyanya kuvepo muchimiro cheCdCl2, asi nickel haipo mune yakasanganiswa fomu. Mushonga wacho uri muchimiro chenickel ions. Iyo NF inochajiswa zvakanaka inoshandiswa kubata nickel ions kuregedza Kuyerera kwemahara kuzadzisa kupatsanurwa pakati pesimbi.
