Iqembu labaphenyi baseChinese lenze intuthuko ebabazekayo ekwelashweni kwamanzi abuhlungu ngokusetshenziswa ngempumelelo kwe-UV / e-Cl ubuchwepheshe ukunciphisa i-membrane gel ethambile. Ucwaningo, muva nje lushicilelwe ngaphakathiUkuxhumana Kwemvelo, iqokomisa indlela yenoveli yokuthuthukisa ukusebenza kahle okutholwa kanye nokusebenza kwe-membrane filltration ezinqubweni zokwelashwa kwamanzi amdaka.

Ukuthuthukiswa okuthuthukile

Ucwaningo luveze ukuthi ukusetshenziswa kwe-UV / e-Cl okuthuthuke kakhulu kwamanzi okuhlolo, ukufeza izinkundla ezifika ku-138% wohlelo lwe-e-cl, no-199% wohlelo lwe-UV, kanye no-198%. Lokhu kuphakamisa ukuthi i-UV / e-Cl iphazamisa ngempumelelo izakhiwo ezijabulisayo ze-membrane, okuholela ekusebenzeni okuthuthukayo okuthuthukile. Ngokusebenzisa uhlelo lwe-SA-BSA Model, abacwaningi bakwazi ukulingisa ukuziphatha okubucayi kwe-polymetic polymetic polymetic polymetic

I-Molefanelar Insights ibe yimishini ethokozisayo

Ucwaningo luye lwahlelwa ekuhlanganiseni kwamaprotheni nama-polysaccharides, eveza ukuthi ibhulodoli le-electrostatic phakathi kwamaqembu e-amino kanye ne-carboxbox lidlala indima ebalulekile ku-membrane fouling. Ngokuhlaziywa kwe-FTIR Spectral ukuhlaziya kanye nokumbumbuluzwa kwe-density (DFT) I-Theory (DFT), abacwaningi bakhombise izindlela ezintathu zokubopha ama-molecular, okubonisa okuthandwa kakhulu kwezindlela ezihambelana nama-polymer axhumanisa. Lokhu okutholakele kuhlinzeka ngokuqonda kwezinga le-molecular yokuthi i-UV / E-CL ikuphikisa lokhu kuhlangana, okuholela ekunciphiseni okuncishisiwe, osayizi abaningi be-floc, nokukhishwa kwamanzi okuthuthukisiwe.

Indima ye-Synergistic yama-radicals e-CL ekunciphiseni okuhle

Ukuhlaziywa okwengeziwe kwabonisa ukuthi ama-chlorine radicals (cl Ucwaningo lubike ukuthi amanani aphezulu okuphendula aphezulu we-CL • Ukusebenzisana nale macromolecule, ukusekela ukusebenza kwe-UV / e-cl ekuboleni ama-membrane. Le nqubo ayizange ihlukanise kuphela izakhiwo ze-SA-BSA ezinhlayiyeni ezincane kodwa futhi yanciphisa kakhulu ukubonakala kwayo kanye nomthamo wayo we-hydration, ngaleyo ndlela ngakwenza buthaka ungqimba olumnandi lwe-gel-efana.

I-Thermodynamic Insights: Isimo samanzi sisho njengento esemqoka

Ucwaningo luphinde lwahlola ukuthi i-thermodynamics ye-membrane ethambile, iqinisekisa ukuthi kwenzeka ukuthi kungenzeka ukuthi kube yilapho izimo zamanzi - kunokuba zithathe izimpande ze-countal noma izici ze-gel. Ukuhlaziywa kwe-thermogravimetric kuveze ukuthi okuqukethwe kwamanzi okubukwayo okulawula izingqimba ezingcolile kwakucishe kube ngu-80%, kanti ukwelashwa kwe-UV / E-CL kunciphise kungaphansi kwe-10%. Lokhu kuguqulwa okuvunyelwe ukukhishwa kwamanzi okulula, ekugcineni kwehlisa ukumelana kwe-filltration kanye nokwenza ngcono ukusebenza kahle kwe-fieltration.

Maqondana nezicelo ezisebenzayo

Ngale miphumela ephoqelelayo, abacwaningi baphakamisa ukulungiselela amapharamitha e-Reason, kufaka phakathi impahla ye-electrode, ukuqina kwe-UV, kanye nesikhathi sokwelashwa, ukuthuthukisa ukuqina kwenqubo. Lolu cwaningo luphinde luphakamise ukuhlanganiswa kwe-UV / e-Cl namanye ama-oxidants, njenge-hydrogen peroxide, ukuthuthukisa ukukhiqizwa okunamandla futhi kuthuthukise ukusebenza kahle kokwelashwa. Ngaphezu kwalokho, abacwaningi bagcizelela amandla okusebenzisa izixazululo ze-NACL eziphansi - njengezamanzi olwandle - ukufezekisa ukwelashwa kwamanzi okuzinzile futhi kungabizi.

Ukuphumelela kwendawo yonke ngobuchwepheshe be-membrane

Ngenkathi lolu cwaningo lwenziwe lusetshenziswa lwalusetshenziswa lwaluwukuthi, okutholakele kunemiphumela efinyelela kude kakhulu edlula ukwelashwa kwamanzi angcolile. Ukuqashelwa kokuvela kwamanzi kusho njengesici esivelele ekunciphiseni ukunqunyelwa kwe-membrane kuphethe ukubaluleka kwendawo yonke ezinqubweni ezihlukile ze-membrane kanye nesikali se-reactor. Lokhu kuqhuma kuvula indlela yokuthola ubuchwepheshe obusebenza kahle futhi obuzinzile ekulweni kwezimboni zokwelapha amanzi emhlabeni jikelele.

Ngokwengeza ukufunwa komhlaba wonke kwabaphathi be-wastewater abasebenza kahle, ubuchwepheshe be-UV / E-CL buveza isixazululo esithembisayo sokwenza ngcono isikhathi eside ukuthuthukisa ulwelwesi, ukunciphisa izindleko zokusebenza, kanye nokwenza ngcono ukusebenza kokwelashwa okuphelele. Njengoba abaphenyi bayaqhubeka nokuhlaziya futhi balinganise le ndlela entsha, ikusasa lokwelashwa kwamanzi amdaka libukeka lisebenza kahle futhi lisimeme.

Ngemininingwane engaphezulu, bheka ucwaningo oluphelele olushicilelwe kwezokuxhumana ngemvelo: [https://www.nature.com/artnecles/41467-025-57878-4]

I-sludge esebenza kahle ne-eco-friendly dengwane etholwa ubuchwepheshe bukaHolly

Ensimini yokwelashwa kwamanzi, uHolly uzibophezele ekuhlinzekeni izisombululo ezinyakazayo eziguqukayo kumakhasimende ethu. I-HLDS yethu ye-HLDS Multi-disc Sludge Dewanting Scress, ngomklamo wayo oyingqayizivele we-Clog-free kanye nomsebenzi wokuzihlanza osezingeni eliphezulu, wehlisa kakhulu izindleko zokwakha zezitshalo zendle. Le mishini isebenzisa uhlelo lokulawula okuzenzakalelayo lwe-PLC, ehlanganisa isikulufa kanye nezindandatho ezihambisayo zokuzihlanza, ezingathatha isikhundla sokucindezela izihlungi zendabuko njengeBelt Press kanye neFrance Press. Uma kuqhathaniswa namasentimitha, ama-HLD ​​asebenza ngamandla aphansi kanye nokusetshenziswa kwamanzi, okwenza kusebenze kahle futhi kube nobungane nemvelo.

I-HLDS Sludge Dewanting Scress Scread isetshenziswa kabanzi ezinhlelweni zamanzi aphansi ezingcolile, kufaka phakathi uMasipala, i-petrochemical, i-fiber, ukwenza amaphepha, imithi, isikhumba, kanye neminye imikhakha yokwelashwa kwamanzi yezimboni. Kuyaphumelela futhi ekwelapheni umquba wepulazi wobisi, i-Palm kawoyela sludge, i-septic sludge, nokuningi. Imishini yethu ifakazelwe kuzinhlelo zokusebenza eziningi zangempela zomhlaba, okubonisa ukusebenza okuhlukile kanye nezinzuzo zezomnotho, ukusiza amabhizinisi kunciphise izindleko zokusebenza ngenkathi kuhlangana nezinhloso zemvelo.

Njengoba ubuchwepheshe bokwelashwa kwamanzi buyaqhubeka nokuvela, izixazululo ezintsha zeHolly zihlinzeka ngamakhasimende emhlabeni wonke ngemishini esebenza kahle futhi engabizi, efaka isandla ekuthuthukisweni okuqhubekayo kwezimboni zokwelapha amanzi Ngenhlanganisela yobuchwepheshe obunqenqemeni kanye neminyaka yokuhlangenwe nakho kwezimboni, uHolly unikezelwe ekunikezeni imishini yokwelashwa kwamanzi athuthukile kakhulu, ukushayela inqubekela phambili yomkhakha kanye nokusimama kwemvelo.
