Ukusetshenziswa kwe-Reverse Osmosis Membrane kanye Nobuchwepheshe obuhlobene Ekuhlanzeni Amanzi

1. Ukwelashwa kwamanzi angcolile

Ukwelashwa kwamanzi angcolile kuwuhlelo oluyisisekelo lwe- reverse osmosis membranes. Ngobuchwepheshe be- reverse osmosis, izinsimbi ezisindayo noma uwoyela oqukethe amanzi angcolile akhiqizwe izimboni zikagesi kanye nezimboni zokunyathelisa nezokudaya zingaphathwa kahle. Ingase futhi isetshenziselwe ukwelapha indle yasemadolobheni, ukuvuza kukadoti, njll., ukuzuza ukutholwa kwemithombo yamanzi.

Enqubweni yokukhiqiza amandla ashisayo, kusetshenziswa inani elikhulu lamanzi okupholisa ajikelezayo, ngokuvamile aqukethe ukungcola okuhlukahlukene kanye ne-turbidity ephezulu. Uma ikhishwa ngokuqondile, izodala ukungcoliswa kwemvelo. Inhlanganisela yezinto ezingenalutho ze-fiber ultrafiltration membrane kanye ne-polyamide composite reverse osmosis membrane ingaphatha amanzi okupholisa ajikelezayo emanzini asebenzisekayo kabusha ngokuxubeka kwamanzi ngaphansi kuka-0.02 NTU kanye nenkomba yokungcola ngaphansi kuka-0.7.

Amanzi angcolile akhiqizwa izimboni zokunyathelisa nokudaya aqukethe inqwaba yama-ion kasawoti, ama-ion color, nezinye izinto. Ukusetshenziswa kwe-ultrafiltration kanye ne-reverse osmosis dual membrane technology kungahlunga izinto eziphilayo, ama-ion kasawoti, njll. emanzini angcolile, futhi ukusetshenziswa kwekhemikhali komoya-mpilo emanzini akhiqiziwe akukho ngaphezu kuka-10 mg/L, okubonisa umphumela obalulekile wokwelashwa kwamanzi.

Ezinqubweni zendabuko zokuhlanza amanzi angcolile aqukethe izinsimbi ezisindayo, ama-ejenti amakhemikhali adinga ukungezwa, futhi izidingo zokusebenza zokwelashwa ziphezulu. Ukusetshenziswa kolwelwesi lwe-osmosis ehlehlayo kanye nobuchwepheshe be-multi-stage reverse osmosis ukwelapha la manzi angcolile kungasusa ngempumelelo izakhi zensimbi ezisindayo eziqukethwe emanzini angcolile.

Izingxenye eziqukethwe kudoti kadoti wasemadolobheni ziningi futhi ziyinkimbinkimbi. Ukusetshenziswa kwe-polyamide reverse osmosis membrane ekwelapheni kwayo kungahlanza i-leachate kadoti ibe sezingeni lokulahla, kufinyelele ukwelashwa kwe-leachate kadoti.

2. Ukukhiqizwa kwamanzi ahlanzekile

Amanzi ahlanzekile anezinhlobonhlobo zezicelo emanzini okuphuza asekhaya, ukukhiqizwa kwezimboni, kanye nemithi. Lezi zinhlelo zokusebenza zinezidingo eziphezulu zamanzi, futhi ukusetshenziswa kwe-osmosis membranes yokwelashwa kwamanzi kudinga ukuhambisana namazinga okukhiqiza adingekayo.

Ngenxa yenqubo yokukhiqiza evuthiwe yamanzi e-ultrapure, izingxenye ezihambisanayo ze-membrane ezivuzayo zingasetshenziswa ekukhiqizeni amanzi e-ultrapure. I-reverse osmosis system ingalawula ukugeleza kwamanzi ukuze kufinyelele ku-650 m ³/h futhi ukhiqize amanzi ahlanzekile ane-conductivity ye-0.3 m S/cm. Inkinga yokungcola kwe-membrane ngesikhathi sokwelashwa kwamanzi ingaxazululwa ngokusebenzisa izindlela zokuhlanza amakhemikhali. Uhlelo olusetshenziswa njengamanje lokwelapha amanzi ahlanzekile luyi-reverse osmosis electrodeionization system.

Mayelana nokukhiqizwa kwamanzi ezimbonini, ukuze kuhlangatshezwane nesidingo sokusetshenziswa, abacwaningi basekhaya bahlongoze isixazululo sokwakha uhlelo lwe-osmosis oluhlehlayo kusetshenziswa izingxenye ze-ultra-low pressure roll composite composite membrane. Ukukhiqizwa kwamanzi olwelwesi olulodwa lolwelwesi oluvunyelekayo kulolu hlelo lungafinyelela ku-41.4 cubic metres ngosuku, ngenani lokugcinwa elingekho ngaphansi kuka-99.7%, elingahlangabezana ngokugcwele nesidingo samanzi sokukhiqizwa kwemboni ye-caustic soda.

Ngaphezu kwalokho, ekukhiqizeni imboni ye-chlor alkali, kuyadingeka ukuhlunga i-Ca ² ⁺ kanye noMg ² ⁺ ama-ion emanzini ngesikhathi sokukhiqiza. Ngakho-ke, ulwelwesi lwe-PVD reverse osmosis lungasetshenziswa ukuze luwasuse, kuyilapho kuqinisekiswa izinga eliphansi lokugcinwa kwe-sodium chloride, ukuze kuzuzwe ukwelashwa kwamanzi nokuhlanzwa ekukhiqizeni imboni ye-chlor alkali.

Ekukhiqizweni kwemithi, kusetshenziswa i-ultra-low pressure polyamide composite permeable membrane module ion separation system nokusebenzisa indlela ye-osmosis enezigaba ezimbili ukukhiqiza amanzi ahlanzekile adingekayo enqubweni yokukhiqiza imithi kungafinyelela imiphumela emihle yokukhiqiza. Lolu hlelo lokuhlanza amanzi lunezinga lokululama elingekho ngaphansi kwama-80% ngemuva kwe-secondary reverse osmosis, okuletha izinzuzo ezinkulu zezomnotho ezinkampanini ezithaka imithi.
