Kugwiritsa Ntchito Reverse Osmosis Membrane ndi Matekinoloje Ofananirako pakuchiritsa kwamadzi
- Kuchiza madzi oipa
Kuchiza ndi madzi onyansa ndi ntchito yaikulu ya reverse osmosis nembanemba. Kudzera muukadaulo wa reverse osmosis, zitsulo zolemera kapena mafuta okhala ndi madzi oyipa opangidwa ndi mafakitale amagetsi ndi mafakitale osindikizira ndi opaka utoto amatha kuthandizidwa bwino. Itha kugwiritsidwanso ntchito poyeretsa zimbudzi zam'tawuni, zotayira zinyalala, ndi zina zambiri, kukwaniritsa kukonzanso kwamadzi.
Popanga mphamvu zamagetsi zotentha, madzi ambiri ozizira ozungulira amagwiritsidwa ntchito, omwe nthawi zambiri amakhala ndi zonyansa zosiyanasiyana komanso kuphulika kwakukulu. Zikatulutsidwa mwachindunji, zitha kuwononga chilengedwe. Kuphatikiza kwa dzenje CHIKWANGWANI ultrafiltration nembanemba zinthu ndi polyamide kompositi reverse osmosis nembanemba amatha kuchitira kuzungulira madzi ozizira madzi reusable ndi madzi turbidity pansi 0.02 NTU ndi kuipitsa index pansi 0.7.
Madzi otayira omwe amapangidwa ndi mafakitale osindikizira ndi utoto amakhala ndi ma ion amchere ambiri, ma ion amitundu, ndi zinthu zina. Kugwiritsa ntchito ultrafiltration ndi reverse osmosis wapawiri nembanemba luso akhoza kusefa zinthu organic, ayoni mchere, etc. mu madzi oipa, ndi kumwa mankhwala mpweya wa madzi opangidwa si apamwamba kuposa 10 mg/L, kusonyeza kwambiri madzi mankhwala zotsatira.
M'njira zachikhalidwe zoyeretsera madzi onyansa omwe ali ndi zitsulo zolemera, mankhwala amafunika kuwonjezeredwa, ndipo zofunikira zogwiritsira ntchito mankhwala ndizokwera. Kugwiritsa ntchito ma nembanemba a reverse osmosis ndi ukadaulo wa multi-stage reverse osmosis pochiza madzi oyipawa amatha kuchotsa bwino zitsulo zolemera zomwe zili m'madzi onyansa.
Zomwe zili m'zinyalala zam'tawuni ndi zambiri komanso zovuta. Kugwiritsiridwa ntchito kwa polyamide reverse osmosis membrane pochiza kungathe kuyeretsa zinyalala za zinyalala mpaka kutayira, kukwaniritsa chithandizo cha leachate ya zinyalala.
- Kupanga madzi koyera
Madzi oyeretsedwa ali ndi ntchito zosiyanasiyana m'madzi akumwa apanyumba, kupanga mafakitale, ndi mankhwala. Mapulogalamuwa ali ndi zofunika kwambiri pamadzi, ndipo kugwiritsa ntchito nembanemba ya reverse osmosis pochiza madzi kumafuna kutsata miyezo yofunikira yopanga.
Chifukwa cha njira yokhwima yopangira madzi a ultrapure, zigawo zofananira zomwe zimatha kugwiritsidwa ntchito pakhungu zitha kugwiritsidwa ntchito popanga madzi a ultrapure. The reverse osmosis system imatha kuwongolera kuthamanga kwamadzi mpaka 650 m ³/ h ndikutulutsa madzi amtundu wa ultrapure okhala ndi ma conductivity a 0.3 m S/cm. Vuto la kuipitsidwa kwa membrane pakuyeretsa madzi kumatha kuthetsedwa pogwiritsa ntchito njira zoyeretsera mankhwala. Njira yomwe imagwiritsidwa ntchito kwambiri pamadzi oyera ndi reverse osmosis electrodeionization system.
Pankhani ya kupanga madzi m'mafakitale, kuti akwaniritse kufunikira kogwiritsidwa ntchito, ofufuza apakhomo apereka njira yothetsera vuto lopanga reverse osmosis system pogwiritsa ntchito zida zamtundu wa ultra-low pressure roll type composite membrane. The limodzi nembanemba madzi kupanga nembanemba permeable mu chiwembu ichi akhoza kufika mamita kiyubiki 41.4 patsiku, ndi mlingo posungira osachepera 99,7%, amene angathe mokwanira kukumana madzi ankafuna caustic soda makampani kupanga.
Kuphatikiza apo, popanga makampani a chlor alkali, ndikofunikira kusefa Ca ² ⁺ ndi Mg ² ⁺ ions m'madzi panthawi yopanga. Chifukwa chake, PVD reverse osmosis nembanemba itha kugwiritsidwa ntchito kuwachotsa, ndikuwonetsetsa kuti sodium chloride imasungidwa pang'ono, kuti ikwaniritse chithandizo chamadzi ndi kuyeretsa pakupanga makampani a chlor alkali.
Popanga mankhwala, kugwiritsa ntchito ultra-low pressure polyamide composite permeable membrane module ion separation system ndikugwiritsa ntchito njira ziwiri zosinthira osmosis kuti apange madzi oyera ofunikira popanga mankhwala amatha kupeza zotsatira zabwino zopanga. Dongosolo lothandizira madzi lili ndi chiwongola dzanja chosachepera 80% pambuyo pa osmosis yachiwiri, yomwe imabweretsa phindu lalikulu pazachuma kumakampani opanga mankhwala.
