Inqubo ebalulekile yobuchwepheshe be-ultrafiltration reverse osmosis
Ukusebenzisa ubuchwepheshe be-ultrafiltration reverse osmosis membrane ukwelapha amanzi angcolile, okubalulekile ukuvimbela ukungcola nokukala kwezingxenye ze-membrane, nokuqinisekisa ukugeleza kwamanzi kulwelwesi. Yamukela lezi zinyathelo ezilandelayo ukuze ulawule ingozi yokungcoliswa kanye neyokungcola kwelwelwesi. Ukwengezwa kwe-flocculant, i-coagulant aid kanye nesoda: ukwengeza inani elifanele le-flocculant (PAC), i-coagulant aid (PAM) kanye nenani elanele lesoda ethangini lokuphendula le-flocculation kungasusa ngaphezu kuka-95% we-Ca2+ kanye nengxenye ye-ion yensimbi esindayo ngemva kokuna kwemvula ethangini le-plate ethambekele le-sedimentation yefomu, ukuze kuncishiswe i-precilutation ebusweni bensimbi. i-membrane yokungena ehlehlayo elandelayo. Njengoba i-PAM iyinhlanganisela ye-polymer enamaketanga amade, ifana ne-polymer material yefilimu ye-RO. Ngemuva kokuthi i-PAM eyeqile ifinyelele ifilimu ye-RO, ifilimu ye-RO izongcoliswa kakhulu futhi ivinjwe, futhi ukugeleza kwe-membrane ngeke kutholakale ngokuhlanza amakhemikhali. Ngakho-ke, inani elifanele kuphela losizo lwe-coagulant elingangezwa, futhi umthamo ohlanganisiwe we-PAC ne-PAM unganqunywa ngokuya ngokuhlolwa kwenkundla.
Ukwengezwa kwe-Acid: Ngenxa yokuthi amanzi angcolile okuqala ane-alkaline futhi ane-pH ephezulu, ama-ion ensimbi esindayo kulula ukwenza imvula engancibiliki endaweni ene-alkali futhi enze isikali endaweni yolwelwesi. Kubaluleke kakhulu ukulungisa i-pH yamanzi aluhlaza ukuze uvimbele ama-ion ensimbi esindayo ukuthi angazinzi futhi akhule phezu kolwelwesi. Engeza i-hydrochloric acid epayipini elingenisayo lesihlungi samanzi aphakathi nendawo amaningi akhiqizwe ethangini le-sedimentation, lungisa i-pH ibe ngu-7~7.5, futhi ulawule ngempumelelo ukungcoliswa kwama-ion ensimbi esindayo ebusweni bolwelwesi olungemuva lwe-osmosis. Isihlungi esiphakathi nendawo: Ukuze uthuthukise ngempumelelo ikhwalithi yamanzi ye-ultrafiltration membrane, isihlungi esine-multi-medium sisethwa phambi kwe-ultrafiltration membrane. Isihlungi esine-multi-medium sisebenzisa isihlabathi se-quartz esimahhadla, isihlabathi se-quartz esihle kanye ne-anthracite evulekile njengesihlungi. Ngemuva kokuthi amanzi angcolile ahlungwe ngesihlungi se-multi-media, ukuthuthumela kwamanzi akhiqizwayo kuhlala ku-1 ~ 2 NTU, okunciphisa umthwalo wokusebenza wesistimu ye-ultrafiltration elandelayo futhi kunciphisa ngokuphumelelayo ingozi yokungcola kwe-membrane ye-ultrafiltration. Ukwengezwa kwe-oxidant: Ukuze kuvinjwe ukunqwabelana kwezinto ezimisiwe kanye nama-microorganisms ebusweni be-ultrafiltration membrane futhi kubangele ukungcola, amaphuzu amabili okwengeza i-oxidant (i-sodium hypochlorite) asethwe ohlelweni lwe-ultrafiltration, elinye lisepayipini lokungena le-ultrafiltration kanti elinye likupayipi le-ultrafiltration elingemuva. Ukwengezwa kwe-oxidant kungenza umehluko wengcindezi ye-transmembrane (TMP) kanye nokugeleza kwesivuno samanzi sokusebenza kwe-ultrafiltration kugcinwe ngokuqinile ezingeni eliklanyelwe. Ukwengezwa kwe-scale inhibitor: ukugcwala kwe-SO42- emanzini angcolile okuqala kuphezulu kakhulu, futhi ama-ion ensimbi esindayo afana ne-Ba2+ ne-Sr2+ angakha kalula usawoti ongancibiliki nge-SO42-. Ngaphezu kwalokho, i-Ca2+ ne-F- ijwayele ukwenza usawoti ongancibiliki. Lawa masawoti angancibiliki yisici esiyinhloko sokwakheka kwezikali ekusebenzeni kwe-osmosis membrane. Ukuze kuvinjwe ukungasebenzi kahle kolwelwesi lwe-osmosis oluhlehlayo, kwenezelwa isikali esifanelekile se-scale inhibitor epayipini elingenisayo le-reverse osmosis membrane. Ngemva kokukhiqizwa kwamanzi e-ultrafiltration ezinzile, lonke izinga lamanzi okukhiqizwa kwamanzi e-ultrafiltration kufanele lihlaziywe, futhi i-DOW FilmtecTM ROSA9.1 isofthiwe yokubala i-osmosis ehlehlayo kufanele isetshenziselwe ukubala ukuthi ingabe ikhona yini ingozi yokukala lapho amanzi e-ultrafiltration engena kulwelwesi lwe-osmosis ehlehlayo. Ngokohlaziyo, kunezingozi ezingalungile ze-BaSO4 kanye ne-SrSO4 emanzini akhiqizwe i-ultrafiltration kulwelwesi lwe-osmosis elingemuva, futhi isofthiwe iphakamisa ukuthi i-scale inhibitor kufanele yengezwe ukuze kwehliswe ingcuphe yokungcola ebusweni. Usebenzisa i-OSMOTREAT OSM35 scale inhibitor (Nalco Industrial Services Co., LTD.), lo mkhiqizo unganciphisa ngempumelelo ingcuphe yokungcola kasawoti oyinzayo njenge-BaSO4, i-SrSO4 ne-CaF2 endaweni ye-osmosis ehlehlayo. Isofthiwe yokubala ye-OSMAS isetshenziselwe ukubala umthamo we-OSM35 scale inhibitor.
