Kushandiswa kweReverse Osmosis Membrane uye Inoenderana Tekinoroji muKurapwa Kwemvura

1. Kugadziriswa kwemvura yakasviba

Kugadziriswa kwemvura yakasviba chinhu chakakosha chekushandisa reverse osmosis membranes. Kuburikidza nereverse osmosis tekinoroji, heavy metal kana mafuta ane tsvina inogadzirwa nemagetsi mafekitori uye mafekitori ekudhinda nekudhaya anogona kunyatsogadziriswa. Inogona zvakare kushandiswa kurapa tsvina yemudhorobha, marara emarara, nezvimwewo, kuwana kudzoreredza zviwanikwa zvemvura.

Mukugadzirwa kwemagetsi ekupisa, mvura yakawanda inotenderera inotonhorera inoshandiswa, iyo inowanzove ine tsvina yakasiyana-siyana uye yakakwirira turbidity. Kana ikaburitswa yakananga, inokonzeresa kusvibiswa kune zvakatipoteredza. Iko kusanganiswa kwehollow fiber ultrafiltration membrane elements uye polyamide composite reverse osmosis membrane inogona kurapa inotenderera mvura inotonhorera mumvura inogona kushandiswa zvakare nemvura turbidity pazasi 0.02 NTU uye kusvibiswa index pazasi 0.7.

Mvura yetsvina inogadzirwa nemafekitari ekudhinda nekudhaya ine maion emunyu akawanda, maion emavara, nezvimwe zvinhu. Kushandiswa kwe ultrafiltration uye reverse osmosis dual membrane tekinoroji inogona kusefa kunze kwe organic matter, salt ions, etc. mumvura yakasviba, uye kemikari okisijeni kushandiswa kwemvura inogadzirwa haisi yakakwirira kudarika 10 mg / L, zvichiratidza kukosha kwekugadzirisa mvura.

Mumaitiro echinyakare ekuchenesa mvura yetsvina ane simbi dzinorema, makemikari anofanirwa kuwedzerwa, uye zvinodiwa zvekurapa zvakakwira. Iko kushandiswa kwe reverse osmosis membranes uye multi-stage reverse osmosis tekinoroji kurapa idzi tsvina inogona kunyatsobvisa inorema simbi zvinhu zviri mumvura yetsvina.

Izvo zvikamu zviri mudhorobha marara leachate akawanda uye akaomarara. Kushandiswa kwepolyamide reverse osmosis membrane yekurapa kwayo kunogona kuchenesa leachate yemarara kusvika padanho rekubuda, kuwana kurapwa kweleachate yemarara.

2. Kugadzirwa kwemvura yakachena

Mvura yakacheneswa ine huwandu hwakawanda hwekushandisa mumvura yekunwa yemumba, kugadzirwa kwemaindasitiri, nemishonga. Izvi zvikumbiro zvine zvakakwirira zvinodikanwa zvemvura, uye kushandiswa kwe reverse osmosis membranes yekurapwa kwemvura kunoda kuteedzera zvinodiwa zvekugadzira.

Nekuda kwemaitiro akakura ekugadzirwa kwemvura yeultrapure, inoenderana permeable membrane zvikamu zvinogona kushandiswa mukugadzirwa kwemvura yekupedzisira. Iyo reverse osmosis system inogona kudzora kuyerera kwemvura kusvika 650 m ³/ h uye inogadzira mvura yekupedzisira ine conductivity ye0.3 m S/cm. Dambudziko rekusvibisa membrane panguva yekurapa kwemvura rinogona kugadziriswa kuburikidza nemakemikari ekuchenesa nzira. Iyo parizvino inowanzo shandiswa yakachena mvura yekurapa system ndiyo reverse osmosis electrodeionization system.

Panyaya yekugadzirwa kwemvura mumaindasitiri, kuitira kuti isangane nezvinodiwa zvekushandisa, vaongorori vemumba vakapa mhinduro yekuvaka reverse osmosis system vachishandisa Ultra-yakaderera kumanikidza roll mhando composite membrane zvikamu. Iyo imwechete membrane mvura kugadzirwa kweiyo permeable membrane muchirongwa ichi inogona kusvika 41.4 cubic metres pazuva, ine mwero wekuchengetedza usingasviki 99.7%, iyo inogona kuzadzisa zvizere kudiwa kwemvura kwecaustic soda indasitiri kugadzirwa.

Uye zvakare, mukugadzirwa kwe chlor alkali indasitiri, zvinodikanwa kusefa kunze Ca ² ⁺ uye mg ² ⁺ ions mumvura panguva yekugadzira. Naizvozvo, PVD reverse osmosis membrane inogona kushandiswa kuvabvisa, uku ichivimbisa yakaderera chiyero chekuchengetedza sodium chloride, kuwana kurapwa kwemvura uye kucheneswa mukugadzirwa kweindasitiri yechlor alkali.

Mukugadzirwa kwemishonga, kushandisa ultra-low pressure polyamide composite permeable membrane module ion separation system uye kushandisa maviri-nhanho reverse osmosis nzira kugadzira mvura yakachena inodiwa mukugadzirwa kwemishonga kunogona kuwana mhedzisiro yakanaka yekugadzira. Ichi chirongwa chekuchenesa mvura chine mwero wekudzoreredza usingasviki 80% mushure mechipiri reverse osmosis, iyo inounza zvakakosha zvehupfumi kumakambani emishonga.
