Iqela labaphandi baseTshayina lenze ukuqhubela phambili kokucocwa kwamanzi amdaka ngokusetyenziswa ngempumelelo kobuchwephesha be-UV/E-Cl ukuthomalalisa ukonakaliswa kwejeli yenwebu. Uphononongo, olusanda kupapashwa kwiUnxibelelwano lweNdalo, igxininisa indlela entsha yokuphucula ukuchithwa kwamanzi kunye nokusebenza kokucoca i-membrane kwiinkqubo zokucocwa kwamanzi amdaka.
Ukomelezwa kokuSetyenziswa kakuhle kwamanzi
Uphononongo lubonise ukuba ukusetyenziswa kwe-UV / E-Cl kuphuculwe kakhulu ukuhamba kwamanzi kwiimvavanyo zokunciphisa amanzi, ukufikelela kwii-fluxes ukuya kwi-138% yenkqubo ye-E-Cl, i-239% yenkqubo ye-UV, kunye ne-198% yolawulo. Oku kuphakamisa ukuba i-UV / E-Cl iphazamisa ngokufanelekileyo izakhiwo ezingcolileyo ze-membrane, ezikhokelela ekusebenzeni okuphuculweyo kokukhupha amanzi. Ngokusebenzisa inkqubo yemodeli ye-SA-BSA, abaphandi baye bakwazi ukulinganisa ukuziphatha okuntsonkothileyo kwe-polymeric substance (EPS) kunye nokuqinisekisa ukubaluleka kweeprotheni kunye neepolysaccharides ekugxothweni kwamanzi amdaka (WAS).
Ukuqonda kweMolekyuli kwiiNdlela zokuTshalalisa
Uphononongo luphonononge intsebenziswano phakathi kweemolekyuli zeeprotheyini kunye neepolysaccharides, luveza ukuba ukudityaniswa kwe-electrostatic phakathi kwamaqela e-amino kunye ne-carboxyl kudlala indima ebalulekileyo ekungcoleni kwe-membrane. Ngohlalutyo lwembonakalo ye-FTIR kunye neTheory ye-Density Functional Theory (DFT), abaphandi bachonge iindlela ezintathu zokubopha iimolekyuli, ezibonisa ukhetho olunamandla lwee-linear conformations ezikhuthaza i-polymer cross-linking. Ezi ziphumo zibonelela ngenqanaba lemolekyuli yokuqonda indlela i-UV/E-Cl ephazamisa ngayo olu nxibelelwano, okukhokelela ekunciphiseni i-viscosity, ubungakanani obukhulu befloc, kunye nokukhutshwa kwamanzi okuphuculweyo.
Indima ye-Synergistic ye-Cl Radicals ekuNciphiseni ukuNciphisa
Uhlalutyo olongezelelweyo lubonise ukuba iiradicals zeklorini (Cl•) zidlala indima ephambili ekuthotyweni kwe-BSA ne-SA, zibe negalelo elingaphezu kwama-90% ekwaphulweni kwazo. Uphononongo lunike ingxelo yezinga lokusabela okuphezulu ngokungaqhelekanga kunxibelelwano lwe-Cl kunye nezi macromolecules, ezixhasa ukusebenza kwe-UV/E-Cl ekuboleni iifolants zenwebu. Le nkqubo ayizange ihlukanise kuphela izakhiwo ze-SA-BSA zibe ngamasuntswana amancinci kodwa yanciphisa kakhulu i-viscosity yabo kunye nomthamo we-hydration, ngaloo ndlela yenza buthathaka i-gel-like fouling layer.
I-Thermodynamic Insights: Imeko yezehlo zaManzi njengeyona nto iphambili
Uphando luye lwaphonononga ngakumbi i-thermodynamics ye-membrane fouling, eqinisekisa ukuba ukwenzeka kwamanzi-kunokuba kune-porosity eqhelekileyo okanye izinto eziguquguqukayo-zilawula ukuziphatha kakubi kwe-gel. Uhlalutyo lwe-Thermogravimetric lubonise ukuba umxholo wamanzi obophelelekileyo kulawulo lwe-foulant layers uphantse ube ngama-80%, ngelixa unyango lwe-UV/E-Cl lwanciphisa ukuya ngaphantsi kwe-10%. Olu tshintsho luvumele ukukhutshwa kwamanzi lula, ekugqibeleni ukunciphisa ukuxhathisa ukuhluza kunye nokuphucula ukusebenza kakuhle.
Ukujonga kwizicelo eziSebenzayo
Ngezi ziphumo zinyanzelisayo, abaphandi bacebisa ukuba kuphuculwe iiparamitha ze-reactor, kubandakanya imathiriyeli ye-electrode, ubunzulu be-UV, kunye nobude bonyango, ukomeleza inkqubo yokuqina. Uphononongo lukwaphakamisa ukudityaniswa kwe-UV/E-Cl kunye nezinye i-oxidants, ezifana ne-hydrogen peroxide, ukuqhubela phambili ukunyusa ukuveliswa kweradical kunye nokuphucula unyango olusebenzayo. Ukongezelela, abaphandi bagxininisa amandla okusebenzisa izisombululo ze-NaCl eziphantsi-ezifana namanzi olwandle-ukuphumeza unyango oluzinzileyo kunye nolunexabiso eliphantsi.
Impumelelo yeHlabathi kwiTekhnoloji yeMembrane
Ngelixa olu phononongo lwaluqhutywa kusetyenziswa i-WAS, iziphumo zalo zineempembelelo ezifikelela kude ngaphaya kokucocwa kwamanzi amdaka. Ukuqondwa kokwenzeka kwamanzi njengeyona nto iphambili kunciphiso lokungcola kwenwebu ibambe ukubaluleka kwendalo ngeenkqubo ezahlukeneyo zemembrane kunye nezikali zereactor. Le mpumelelo ivula indlela yetekhnoloji yokucoca esebenza ngakumbi kwaye ezinzileyo kumashishini okucoca amanzi kwihlabathi liphela.
Ngokunyuka kwemfuno yehlabathi yolawulo olusebenzayo lwamanzi amdaka, itekhnoloji ye-UV/E-Cl ibonelela ngesisombululo esithembisayo sokuphucula ubomi obude be-membrane, ukunciphisa iindleko zokusebenza, kunye nokuphucula ukusebenza konyango ngokubanzi. Njengoko abaphandi beqhubeka nokucokisa kunye nokunyusa le ndlela entsha, ikamva lokucocwa kwamanzi amdaka libukeka lisebenza ngokufanelekileyo kwaye lizinzile.
