Ib pab pawg ntawm cov kws tshawb fawb Suav tau ua qhov kev nce qib hauv kev kho dej khib nyiab nrog kev ua tiav ntawm UV / E-Cl thev naus laus zis los txo cov membrane gel fouling. Txoj kev tshawb no, tsis ntev los no tau luam tawm hauvNature Communications, qhia txog txoj hauv kev tshiab los txhim kho dewatering efficiency thiab membrane filtration kev ua tau zoo hauv cov txheej txheem dej khib nyiab.
Txhim kho Dewatering Efficiency
Txoj kev tshawb no tau pom tias daim ntawv thov ntawm UV / E-Cl tau txhim kho cov dej ntws zoo hauv kev sim dewatering, ua tiav cov fluxes txog li 138% ntawm E-Cl system, 239% ntawm UV system, thiab 198% ntawm kev tswj. Qhov no qhia tias UV / E-Cl cuam tshuam cov txheej txheem fouling, ua rau kev txhim kho dewatering kev ua tau zoo. Los ntawm kev siv tus qauv SA-BSA, cov kws tshawb fawb tau simulate complex extracellular polymeric substance (EPS) tus cwj pwm thiab paub meej tias qhov cuam tshuam ntawm cov proteins thiab polysaccharides hauv cov dej khib nyiab (WAS) dewatering.
Molecular Insights rau Fouling Mechanisms
Txoj kev tshawb no delved rau hauv kev sib cuam tshuam ntawm cov proteins thiab polysaccharides, qhia tias electrostatic bridging ntawm amino thiab carboxyl pawg plays lub luag haujlwm tseem ceeb hauv daim nyias nyias fouling. Los ntawm FTIR spectral tsom xam thiab Density Functional Theory (DFT) simulations, cov kws tshawb fawb tau txheeb xyuas peb hom molecular binding hom, qhia qhov kev nyiam muaj zog rau cov kab sib txuas uas txhawb nqa kev sib txuas ntawm polymer. Cov kev tshawb pom no muab kev nkag siab txog qib molecular ntawm yuav ua li cas UV / E-Cl cuam tshuam cov kev sib cuam tshuam no, ua rau txo cov viscosity, loj floc loj, thiab txhim kho cov dej tso tawm.
Synergistic Lub luag haujlwm ntawm Cl Radicals hauv Fouling Mitigation
Kev soj ntsuam ntxiv tau pom tias cov tshuaj chlorine radicals (Cl•) ua lub luag haujlwm tseem ceeb hauv kev degradation ntawm BSA thiab SA, pab txhawb ntau dua 90% rau lawv qhov kev puas tsuaj. Txoj kev tshawb no qhia tshwj xeeb tshaj yog cov tshuaj tiv thaiv tus nqi tas mus li rau Cl• kev cuam tshuam nrog cov macromolecules, txhawb kev ua haujlwm ntawm UV / E-Cl hauv decomposing membrane foulants. Cov txheej txheem no tsis tsuas yog fragmented SA-BSA cov qauv rau hauv cov khoom me me tab sis kuj txo lawv cov viscosity thiab hydration peev xwm, yog li ua rau cov gel zoo li fouling txheej tsis muaj zog.
Thermodynamic Insights: Dej tshwm sim xeev raws li qhov tseem ceeb Factor
Cov kev tshawb fawb ntxiv tshawb xyuas cov thermodynamics ntawm daim nyias nyias fouling, lees paub tias cov dej tshwm sim hauv xeev - tsis yog cov pa porosity lossis permeability yam - ua tus coj tus cwj pwm gel fouling. Kev tshuaj ntsuam xyuas thermogravimetric tau qhia tias cov ntsiab lus ntawm cov dej khi hauv cov txheej txheem foulant yog ze li ntawm 80%, thaum kho UV / E-Cl txo nws qis dua 10%. Qhov kev hloov pauv no tso cai rau kev tso dej yooj yim dua, thaum kawg txo qis kev pom kev ua haujlwm thiab txhim kho pom kev ua haujlwm zoo.
Mus rau kev siv tswv yim
Nrog rau cov txiaj ntsig zoo no, cov kws tshawb fawb pom zoo kom ua kom zoo dua cov khoom siv hluav taws xob, suav nrog cov khoom siv hluav taws xob, UV siv, thiab lub sijhawm kho, txhawm rau txhim kho cov txheej txheem scalability. Txoj kev tshawb no tseem qhia txog kev koom ua ke ntawm UV / E-Cl nrog lwm cov oxidants, xws li hydrogen peroxide, txhawm rau txhawb kev tsim cov radical thiab txhim kho kev kho mob. Tsis tas li ntawd, cov kws tshawb fawb hais txog qhov muaj peev xwm los siv cov kev daws teeb meem qis dua NaCl - xws li dej hiav txwv - kom ua tiav cov dej khib nyiab ruaj khov thiab muaj txiaj ntsig zoo.
Ib qho Universal Breakthrough hauv Membrane Technology
Thaum txoj kev tshawb fawb no tau ua los ntawm WAS, nws qhov kev tshawb pom muaj qhov cuam tshuam loj tshaj li kev kho dej khib nyiab. Kev lees paub ntawm cov dej tshwm sim hais tias yog qhov tseem ceeb tshaj plaws hauv cov txheej txheem membrane fouling mitigation tuav qhov tseem ceeb thoob ntiaj teb thoob plaws cov txheej txheem membrane sib txawv thiab cov nplai reactor. Qhov kev ua tiav no ua rau txoj hauv kev kom muaj txiaj ntsig zoo dua thiab muaj txiaj ntsig zoo hauv kev lag luam kho dej thoob ntiaj teb.
Nrog nce thoob ntiaj teb kev thov rau kev tswj dej pov tseg kom zoo, UV / E-Cl thev naus laus zis nthuav tawm cov lus cog tseg rau kev txhim kho daim nyias nyias, txo cov nqi ua haujlwm, thiab txhim kho kev kho mob tag nrho. Raws li cov kws tshawb fawb txuas ntxiv txhim kho thiab ntsuas qhov kev hloov kho tshiab no, yav tom ntej ntawm kev kho dej khib nyiab zoo li ua kom muaj txiaj ntsig thiab ruaj khov.
