Nanofiltration nembanemba akhoza kusunga nano-kakulidwe zipangizo, ndi makhalidwe ena kudziwa enieni mtundu ntchito zosiyanasiyana nanofiltration nembanemba, amene akhoza kugawidwa mu mbali zotsatirazi.
1. Kugwiritsa ntchito nembanemba ya nanofiltration m'madzi ozizira.
Chifukwa ma ion awiriwa amalandidwa bwino ndipo kutsika kwapansi kumatha kuyendetsedwa pamitengo yamadzi okwera, kuwawa kumachotsedwa, komwe kumatenga msika wokonzanso wa sodium.Ubwino wake waukulu ndikuti alibe tizilombo toyambitsa matenda ndipo safuna kubadwanso., Amalowa m'madzi ndi zinthu zamoyo, zosavuta, sizitenga malo, etc. Komanso, zimakhala pafupi ndi njira ya ndalama ndi mtengo, kotero pali ntchito yoyenera komanso yachikhalidwe m'munda uno.
2. Kugwiritsa ntchito nanofiltration nembanemba mu kuyeretsa madzi akumwa.
Chifukwa cha kutsalira kwa kuipitsidwa kwa madzi, kuyesa kwa zinthu zomwe zikukhudzidwa kwatsimikizira kuti nanofiltration nembanemba zimatha kuchotsa zotsalira zapoizoni, zotsalira za herbicides, mankhwala ophera tizilombo, zinthu zachilengedwe, zinthu zachilengedwe, mtundu wamadzi, ndi sulfide yopangidwa mu. njira yophera tizilombo toyambitsa matenda.Mchere ndi nitrate, etc. Ulinso ndi ubwino wa madzi abwino, kukhazikika, mlingo wochepa wa mankhwala, zosavuta zazing'ono, zopulumutsa mphamvu, kasamalidwe ndi kukonza, ndipo makamaka kutulutsa ziro.Chifukwa chake, ma nanofiltration nembanemba atha kukhala ukadaulo wokondeka pakuyeretsa koyera m'zaka za zana la 21.
3. Kugwiritsa ntchito nanofiltration nembanemba pa mchere mu porous pamwamba.
Pakukula kwa ndende yamchere m'madzi apansi panthaka, m'malo olamulidwa ndi ulimi, index yamadzi yamadzi ili kutali komanso pafupi, ndipo ukadaulo wa reverse osmosis ungagwiritsidwe ntchito kukumba mchere ndi zinthu zina.Koma chifukwa madzi kuchira mlingo ndi mkulu.Pa nthawi yomweyi, chithandizo cha condensate ndi vuto.Nthawi zambiri, njira yosinthira ion imafunika kuti muchepetse madzi oyipa.
Kumbali inayi, ma ion osinthira ma ion amakonda kusinthanitsa ma ion a divalent komanso apamwamba kwambiri.Ngati zomwe zili zamtengo wapatali muzitsulo zochepetsera zimawonjezera mtengo wokonza, kusinthika kwapakati kudzawonjezera madzi akuluakulu poyamba.Mchere wamchere wambiri umagwiritsidwa ntchito ndi nanofiltration nembanemba ndiyeno amathandizidwa ndi njira yosinthira ion, nthawi yochizira imatha kupitilira 2 mpaka 3.
The yankho lili ambiri mchere mchere.Pambuyo pa gawo la kusintha kwa sodium ion, ma ion a inorganic amasinthidwa ndi ma chloride.Panthawi imeneyi, nitrate zili m'madzi zimakwaniritsa zofunikira za mchere wamchere.Ubwino wake ndi: imatha kulowa mu nitrate, ndipo kuchuluka kwa kuchira kwamadzi ndikokwera.Njira imeneyi yakhala ikugwiritsidwa ntchito kwambiri ku Germany.
4. Kugwiritsa ntchito nanofiltration nembanemba mu mankhwala masamba.
Chifukwa chotsaliracho chimakhala ndi thonje yambiri, yomwe imatha kulowa ndikuyamwa wina ndi mzake, nkhuni zakuda ndi nkhuni zowonongeka zomwe zimapangidwira potengera nkhuni zakuda ndi zamkati zamatabwa zimatengedwa ndi chinthu ndi njira yoyamwitsa chifukwa zinthu zambiri za organic mu peat. ali ndi mlandu wolakwika ndipo amatsutsidwa mosavuta.Nanofiltration nembanemba imawonongeka m'malo moyambitsa kuipitsa kwakukulu.Mwachitsanzo, nanofiltration nembanemba ntchito decolor zinyalala madzi opangidwa mu alkali m'zigawo siteji ya nkhuni pulping, riboni nembanemba, biomembrane ndi nthaka lignin mu zinyalala zamadzimadzi akhoza intercepted, ndi ayoni monovalent ion kuti safunika kulandidwa. akhoza kusangalatsidwanso kudzera mu nembanemba, The decolorization mlingo wa filimu kufika 98%.
5. Kugwiritsa ntchito nembanemba za nanofiltration muzamankhwala apamwamba azimbudzi.
Chithandizo cha kusefera kwa membrane ndi njira yofunikira yodziwira kukonzanso kwa zimbudzi.Njira zake zazikulu ndi monga flocculation sedimentation, disinfection, ndi njira zina zothandizira.The ndondomeko pambuyo mankhwala nembanemba kumaphatikizapo mankhwala nembanemba.Onse amatha kugwiritsa ntchito madzi oyeretsedwa.
Chachisanu ndi chimodzi, nembanemba ya nanofiltration imakhala ndi ntchito zobisika pochiza.
Popanga ma electroplating ndi kupanga aloyi, madzi ambiri nthawi zambiri amatsukidwa chifukwa chokhala ndi mkuwa wambiri, monga faifi tambala, chitsulo, ndi zinki.Kusinthidwa kukhala matope, ngati teknoloji ya nanofiltration membrane ikugwiritsidwa ntchito, zoposa 90% ya gawolo likhoza kubwezeretsedwanso kuti liyeretsedwe, ndipo mtengo weniweni ukhoza kuchepetsedwa ndi nthawi za 10 kuti kuchepetsako kugwiritsidwenso ntchito.
Pazifukwa zoyenera, nanofiltration nembanemba angathenso kukwaniritsa kulekana kwa zinthu zitsulo zosiyanasiyana mu njira yothetsera, monga kulekanitsa Cd ndi Ni, choyamba kuwasandutsa CdCl2 ndi NiCl2, ndiyeno kuwonjezera NaCl kupanga mlandu ndi uncharged zovuta motero Zinthu.Pamene kuchuluka kwa NaCl ndi 01mol / L pamene maonekedwe akuwonekera mu yankho, makamaka amakhalapo mu mawonekedwe a CdCl2, koma nickel palibe mu mawonekedwe ophatikizidwa.Pagululi ndi mawonekedwe a nickel ions.NF yoyikidwa bwino imagwiritsidwa ntchito kulowetsa ma nickel ions kuti alole Kuyenda kwaulere kuti akwaniritse kulekanitsa pakati pa zitsulo.
