Ukusetyenziswa kweMembrane ye-Reverse Osmosis kunye neeTekhnoloji eziNxulumeneyo kuNyango lwaManzi

1. Ukucocwa kwamanzi amdaka

Ukucocwa kwamanzi amdaka sisicelo esingundoqo se-reverse osmosis membranes. Ngokusebenzisa itekhnoloji ye-osmosis ebuyela umva, isinyithi esinzima okanye i-oyile equlathe amanzi amdaka aveliswa ngamaziko ombane kunye nemizi-mveliso yokushicilela kunye nokudaya inokucocwa ngokufanelekileyo. Isenokusetyenziswa ukunyanga ilindle ezidolophini, inkunkuma evuzayo, njl.njl., ukuphumeza ukufunyanwa kwakhona kobutyebi bamanzi.

Kwinkqubo yokuvelisa amandla okushisa, kusetyenziswe inani elikhulu lamanzi okupholisa ajikelezayo, ahlala equlethe ukungcola okuhlukeneyo kunye ne-turbidity ephezulu. Ukuba ikhutshwe ngokuthe ngqo, iya kubangela ungcoliseko kokusingqongileyo. Udibaniso lwefiber ultrafiltration membrane elements kunye ne polyamide composite reverse osmosis inwebu inokunyanga ukujikeleza kwamanzi okupholisa kumanzi anokuphinda asebenziseke kunye ne-turbidity yamanzi ngaphantsi kwe-0.02 NTU kunye nesalathisi songcoliseko esingaphantsi kwe-0.7.

Amanzi amdaka aveliswa yimizi-mveliso yokushicilela nawokudaya aneeyoni ezininzi zetyuwa, ii-ion zemibala kunye nezinye izinto. Ukusetyenziswa kwe-ultrafiltration kunye ne-reverse osmosis iteknoloji ye-membrane ye-dual inokucoca i-organic matter, i-ion yetyuwa, njl njl kumanzi amdaka, kwaye ukusetyenziswa kweekhemikhali ze-oksijini zamanzi avelisiweyo akukho ngaphezu kwe-10 mg / L, ebonisa umphumo obalulekileyo wonyango lwamanzi.

Kwiinkqubo zokucocwa kwamanzi amdaka emveli aqulethe isinyithi esinzima, ii-agent zeekhemikhali kufuneka zongezwe, kwaye iimfuno zokusebenza konyango ziphezulu. Ukusetyenziswa kweembrane ze-osmosis ezibuyela umva kunye netekhnoloji ye-multi-stage reverse osmosis ukunyanga la manzi amdaka kunokususa ngokufanelekileyo izinto zentsimbi ezinzima eziqulethwe kumanzi amdaka.

Amacandelo aqulethwe kwinkunkuma yenkunkuma yasezidolophini zininzi kwaye zintsonkothile. Ukusetyenziswa kwe-polyamide reverse osmosis membrane yonyango lwayo inokucoca i-leachate yenkunkuma kwinqanaba lokukhupha, ukufezekisa unyango lwe-leachate yenkunkuma.

2. Imveliso yamanzi acocekileyo

Amanzi acociweyo anoluhlu olubanzi lwezicelo kumanzi okusela asekhaya, imveliso yamashishini, kunye namayeza. Ezi zicelo zineemfuno eziphezulu zamanzi, kwaye ukusetyenziswa kwe-membrane ye-osmosis ye-reverse kunyango lwamanzi kufuna ukuthotyelwa kwemigangatho efunekayo yokuvelisa.

Ngenxa yenkqubo yemveliso evuthiweyo yamanzi e-ultrapure, amacandelo ahambelanayo asebenzayo kwi-membrane angasetyenziswa kwimveliso yamanzi e-ultrapure. Inkqubo ye-osmosis ye-reverse inokulawula ukuhamba kwamanzi ukufikelela kwi-650 m ³/ h kwaye uvelise amanzi aphezulu kunye ne-conductivity ye-0.3 m S/cm. Ingxaki yokungcola kwe-membrane ngexesha lokunyanga kwamanzi ingasombululwa ngeendlela zokucoca iikhemikhali. Inkqubo yonyango lwamanzi acocekileyo esetyenziswa ngoku yireverse osmosis electrodeionization system.

Ngokubhekiselele kwimveliso yamanzi kwimizi-mveliso, ukuze kuhlangatyezwane nemfuno yokusetyenziswa, abaphandi basekhaya bacebise isisombululo sokwakha inkqubo ye-osmosis ebuyela umva usebenzisa i-ultra-low pressure roll type composite membrane components. Imveliso enye yamanzi inwebu ye-membrane evuzayo kule nkqubo inokufikelela kwi-41.4 cubic metres ngosuku, kunye nesantya sokugcinwa esingekho ngaphantsi kwe-99.7%, esinokuhlangabezana ngokupheleleyo nemfuno yamanzi yemveliso ye-caustic soda.

Ukongeza, kwimveliso ye-alkali ye-chlor, kuyimfuneko ukuhluza ngaphandle kwe-Ca² ⁺ kunye noMg ² ⁺ ion emanzini ngexesha lenkqubo yemveliso. Ngoko ke, i-PVD i-reverse osmosis membrane ingasetyenziselwa ukususa, ngelixa iqinisekisa izinga eliphantsi lokugcinwa kwe-sodium chloride, ukufezekisa unyango lwamanzi kunye nokucocwa kwimveliso ye-chlor alkali yoshishino.

Kwimveliso yamachiza, usebenzisa i-ultra-low pressure polyamide composite permeable membrane module ion separation system kunye nokusebenzisa indlela ye-osmosis yamanqanaba amabini ukuvelisa amanzi acocekileyo afunekayo kwinkqubo yokuvelisa amayeza anokufikelela kwiziphumo ezilungileyo zokuvelisa. Esi sikimu sokucocwa kwamanzi sinesantya sokubuyisela esingekho ngaphantsi kwe-80% emva kwe-secondary reverse osmosis, nto leyo izisa iinzuzo ezibalulekileyo zoqoqosho kwiinkampani zamayeza.
