Ukusetshenziswa kobuchwepheshe be-membrane ye-ultrafiltration ekwelashweni kwamanzi okuphuza
Ngokuthuthuka okuqhubekayo kwenqubo yokufudukela emadolobheni, inani labantu basemadolobheni liye lagxila kakhulu, imithombo yendawo yasemadolobheni kanye nokuhlinzekwa kwamanzi asekhaya kancane kancane kuba esinye sezizathu eziyinhloko zokukhawulela ukuthuthukiswa kwamadolobha.Ngokukhula okuqhubekayo kwenani labantu basemadolobheni, ukusetshenziswa kwamanzi nsuku zonke kwedolobha kuyaqhubeka nokwanda, futhi umthamo wansuku zonke wamanzi angcolile wedolobha nawo ubonisa umkhuba wokukhula okuqhubekayo.Ngakho-ke, indlela yokuthuthukisa izinga lokusetshenziswa kwemithombo yamanzi yasemadolobheni kanye nokunciphisa izinga lokungcoliswa kwemfucuza kanye nokukhipha amanzi sekuyinkinga enkulu okufanele ixazululwe ngokushesha.Ukwengeza, imithombo yamanzi ahlanzekile iyindlala kakhulu futhi isidingo sabantu sokuhlanzeka kwamanzi siya ngokuya sikhula.Kudingekile ukudinga ukuthi okuqukethwe kwezinto eziyingozi emithonjeni yamanzi, okungukuthi, ukungcola, kube ngaphansi, okubeka phambili izidingo eziphakeme zokuhlanzwa kwendle kanye nobuchwepheshe bokwelashwa.Ubuchwepheshe be-membrane ye-Ultrafiltration bunezici ezijwayelekile ze-physicochemical nokuhlukanisa, ukumelana nezinga lokushisa eliphezulu nokumelana namakhemikhali, kanye ne-pH ezinzile.Ngakho-ke, inezinzuzo eziyingqayizivele zohlelo lokusebenza ekwelapheni kwamanzi okuphuza emadolobheni, okungasusa ngokuphumelelayo izinto eziphilayo, izinhlayiya ezimisiwe kanye nezinto eziyingozi emanzini okuphuza, futhi kuqinisekiswe ukuphepha kwamanzi okuphuza asemadolobheni.
Ukusetshenziswa kobuchwepheshe be-membrane ye-ultrafiltration ku-seawater desalination
Imithombo yamanzi ahlanzekile emhlabeni ayitholakali kakhulu, kodwa imithombo yamanzi ihlanganisa cishe u-71% wendawo yonke yomhlaba, okungukuthi, imithombo yamanzi olwandle engasebenziseki emhlabeni inothile kakhulu.Ngakho-ke, ukukhipha usawoti emanzini kuyisinyathelo esibalulekile sokuxazulula ukushoda kwemithombo yamanzi ahlanzekile yabantu.Inqubo yokukhipha usawoti emanzini olwandle iyinqubo eyinkimbinkimbi futhi yesikhathi eside.Ukuhlola kwesikhathi eside okuncike ekuhlanzeni izinsiza zamanzi olwandle angeke asetshenziswe ngokuqondile emithonjeni yamanzi ahlanzekile angasetshenziswa ngokuqondile.Ngokuthuthuka okusheshayo kwesayensi nobuchwepheshe, ubuchwepheshe bokukhipha usawoti emanzini olwandle buye bavuthwa kancane kancane futhi baba ngcono.Isibonelo, ukusetshenziswa kobuchwepheshe be-electro-osmosis kungafinyelela ukuchithwa kwamanzi olwandle ngesikhathi esisodwa, kodwa ukusetshenziswa kwamandla okukhipha usawoti emanzini olwandle kukhulu kakhulu.Ubuchwepheshe be-membrane ye-Ultrafiltration bunezici eziqinile zokuhlukanisa, ezingalawula ngempumelelo inkinga ye-osmosis ehlanekezela inqubo yokukhipha usawoti emanzini olwandle, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kokukhipha usawoti emanzini olwandle nokunciphisa ukusetshenziswa kwamandla okukhipha usawoti emanzini olwandle.Ngakho-ke, ubuchwepheshe bolwelwesi be-ultrafiltration bunamathemba abanzi wokusebenzisa ekwelashweni kokukhipha usawoti emanzini olwandle esikhathini esizayo.
Ukusetshenziswa kwe-Ultrafiltration Membrane Technology ku-Domestic Sewage
Ngokuqhubeka nokujula kwenqubo yokufudukela emadolobheni, ukuthuthwa kwendle nsuku zonke emadolobheni kuye kwanda kakhulu.Indlela yokusebenzisa kabusha indle yasekhaya yasemadolobheni kuyinkinga ephuthumayo okufanele ixazululwe.Njengoba sonke sazi, indle yasemadolobheni ayiyona nje isamba esikhulu sokukhishwa, kodwa futhi inothile ngezinto ezinamafutha, izinto eziphilayo kanye nenani elikhulu lama-microorganisms e-pathogenic emzimbeni wamanzi, okuletha usongo olukhulu endaweni ezungezile yemvelo kanye nempilo. yabahlali.Uma indle enkulu yasekhaya ikhishelwa ngokuqondile endaweni ezungezile, izongcolisa kakhulu imvelo ezungeze idolobha, ngakho-ke kufanele ikhishwe ngemva kokuhlanzwa kwendle.Ubuchwepheshe be-membrane ye-Ultrafiltration bunezici eziqinile ze-physicochemical nokuhlukanisa, futhi bungahlukanisa ngokuphumelelayo izinto eziphilayo nama-bacterium emanzini.Ubuchwepheshe be-membrane ye-ultrafiltration busetshenziselwa ukuhlunga i-phosphorus isiyonke, i-nitrogen ephelele, i-chloride ions, isidingo samakhemikhali womoya-mpilo, ama-ion ancibilikisiwe aphelele, njll emanzini asekhaya asemadolobheni, ukuze bonke bahlangabezane nezindinganiso eziyisisekelo zamanzi asemadolobheni.
