Ithimba labacwaningi baseShayina lenze intuthuko enkulu ekuhlanzeni amanzi angcolile ngokusebenzisa ngempumelelo ubuchwepheshe be-UV/E-Cl ukuze kuncishiswe ukungcola kwejeli. Ucwaningo, olusanda kushicilelwa kuUkuxhumana Kwemvelo, igqamisa indlela entsha yokuthuthukisa ukusebenza kahle kokukhipha amanzi kanye nokusebenza kokuhlunga ulwelwesi ezinqubweni zokuhlanza amanzi angcolile.
Ukusebenza Okuthuthukisiwe Kokukhipha Amanzi
Ucwaningo lubonise ukuthi ukusetshenziswa kwe-UV/E-Cl kuthuthukisa kakhulu ukugeleza kwamanzi ekuhlolweni kokukhipha amanzi, kufinyelele ukugeleza okufika ku-138% we-E-Cl system, 239% yohlelo lwe-UV, kanye no-198% wokulawula. Lokhu kuphakamisa ukuthi i-UV/E-Cl iphazamisa ngempumelelo izakhiwo ezingcolisa ulwelwesi, okuholela ekusebenzeni okuthuthukisiwe kokukhipha amanzi. Ngokusebenzisa imodeli yesistimu ye-SA-BSA, abacwaningi bakwazile ukulingisa ukuziphatha okuyinkimbinkimbi kwe-polymeric substance (EPS) futhi baqinisekisa ukuhlobana kwamaphrotheni nama-polysaccharides ekukhipheni amanzi angcolile (WAS).
I-Molecular Insights Ezinkambisweni Zokungcolisa
Ucwaningo lwangena ekusebenzisaneni kwamangqamuzana amaprotheni nama-polysaccharides, lwembula ukuthi ukuhlangana kwe-electrostatic phakathi kwamaqembu e-amino ne-carboxyl kudlala indima ebalulekile ekungcolisweni kolwelwesi. Ngokuhlaziya okubonakalayo kwe-FTIR kanye nokulingiswa kwe-Density Functional Theory (DFT), abacwaningi bahlonze izindlela ezintathu zokubopha amangqamuzana, okubonisa ukukhetha okunamandla kokuvumelana komugqa okukhuthaza ukuxhumanisa kwe-polymer. Lokhu okutholakele kunikeza ukuqonda kweleveli yamangqamuzana ukuthi i-UV/E-Cl ikuphazamisa kanjani lokhu kusebenzisana, okuholela ekuncipheni kwe-viscosity, osayizi abakhulu be-floc, kanye nokukhululwa kwamanzi okuthuthukisiwe.
Indima Ye-Synergistic ye-Cl Radicals ekunciphiseni ukungcolisa
Ukuhlaziywa okwengeziwe kubonise ukuthi ama-chlorine radicals (Cl•) adlala indima enkulu ekwehlisweni kwe-BSA ne-SA, abe negalelo elingaphezu kwama-90% ekuqhekekeni kwawo. Ucwaningo lubike ukuguquguquka kwezinga lokusabela okuphezulu ngokukhethekile kokusebenzelana kwe-Cl nalawa ma-macromolecules, okusekela ukusebenza kahle kwe-UV/E-Cl ekuboleni ama-foulants olwelwesi. Le nqubo ayizange ihlukanise nje izakhiwo ze-SA-BSA zibe izinhlayiya ezincane kodwa futhi yanciphisa kakhulu i-viscosity yazo kanye nomthamo we-hydration, ngaleyo ndlela yenza buthaka ungqimba olungcolile olufana nejeli.
I-Thermodynamic Insights: Isimo Sokwenzeka Kwamanzi Njengesici Esibalulekile
Ucwaningo lwabuye lwahlola i-thermodynamics ye-membrane fouling, iqinisekisa ukuthi ukwenzeka kwamanzi-kunokuba nezici ezivamile ze-porosity noma i-permeability-zilawula ukuziphatha okungalungile kwejeli. Ukuhlaziywa kwe-Thermogravimetric kwembula ukuthi okuqukethwe kwamanzi okuboshiwe ezingqimbeni ezingcolile zokulawula cishe kwakucishe kube ngu-80%, kuyilapho ukwelashwa kwe-UV/E-Cl kwehlisele ngaphansi kuka-10%. Lokhu kushintsha kuvumele ukudedelwa kwamanzi kalula, ekugcineni kwehlisa ukumelana nokuhlunga kanye nokwenza ngcono ukusebenza kahle kokuhlunga.
Ibheke Izicelo Ezisebenzayo
Ngale miphumela ephoqelelayo, abacwaningi baphakamisa ukwenza ngcono amapharamitha we-reactor, okuhlanganisa impahla ye-electrode, ukuqina kwe-UV, nobude besikhathi sokwelashwa, ukuthuthukisa ukuqina kwenqubo. Lolu cwaningo luphinde luphakamise ukuhlanganiswa kwe-UV/E-Cl namanye ama-oxidants, njenge-hydrogen peroxide, ukuze kuthuthukiswe ukukhiqizwa okunamandla futhi kuthuthukiswe ukusebenza kahle kokwelashwa. Ukwengeza, abacwaningi bagcizelela amandla okusebenzisa izixazululo ze-NaCl ezisezingeni eliphansi-njengamanzi olwandle-ukufeza ukwelashwa kwamanzi angcolile okusimeme futhi okungabizi.
Ukuphumelela Okubanzi Kwezobuchwepheshe Be-Membrane
Nakuba lolu cwaningo lwenziwe kusetshenziswa i-WAS, okutholakele kunemiphumela efinyelela kude ngale kokwelashwa kwamanzi angcolile. Ukuqashelwa kokwenzeka kwamanzi kuyisici esiyinhloko ekunciphiseni ukungcoliswa kwe-membrane kubambe ukubaluleka kwendawo yonke kuzo zonke izinqubo zolwelwesi oluhlukene nezikali ze-reactor. Lokhu kuphumelela kuvula indlela yobuchwepheshe bokuhlunga obusebenza kahle futhi obuqhubekayo ezimbonini zokuhlanza amanzi emhlabeni jikelele.
Ngokukhula kwesidingo somhlaba wonke sokuphathwa kahle kwamanzi angcolile, ubuchwepheshe be-UV/E-Cl bunikeza isixazululo esithembisayo sokuthuthukisa impilo ende ye-membrane, ukunciphisa izindleko zokusebenza, kanye nokuthuthukisa ukusebenza kokwelashwa kukonke. Njengoba abacwaningi beqhubeka nokucwenga futhi bekhulisa le ndlela entsha, ikusasa lokuhlanza amanzi angcolile libukeka lisebenza ngempumelelo futhi lizinzile.

I-Dewatering Ephumelelayo Ne-Eco-Friendly Sludge nge-Holly's Technology
Emkhakheni wokuhlanza amanzi, uHolly uzibophezele ekunikezeni amakhasimende ethu izixazululo ezintsha zokususa amanzi ngodaka. I-HLDS Multi-disc Sludge Dewatering Screw Press yethu ye-HLDS, enomklamo wayo oyingqayizivele ongena-clog kanye nomsebenzi othuthukisiwe wokuzihlanza, inciphisa kakhulu izindleko zokwakha izitshalo zendle. Lesi sixhobo sisebenzisa isistimu yokulawula ye-PLC ezenzakalelayo, ehlanganisa isikulufu nezindandatho ezihambayo ukuze zizihlanze, ezingangena esikhundleni somshini wokuhlunga wendabuko njengokucindezela ibhande nokucindezela uhlaka. Uma kuqhathaniswa nama-centrifuges, i-HLDS isebenza ngamandla aphansi kanye nokusetshenziswa kwamanzi, okwenza isebenze kahle futhi ihambisane nemvelo.
I-HLDS Sludge Dewatering Screw Press isetshenziswa kabanzi ezinhlelweni ezahlukene zokuhlanza amanzi angcolile, okuhlanganisa umasipala, i-petrochemical, i-chemical fiber, ukwenza amaphepha, imithi, isikhumba, neminye imikhakha yokuhlanza amanzi ezimbonini. Iyasebenza futhi ekwelapheni Umquba Wepulazi Lobisi, Udaka lwamafutha esundu, udaka lwe-Septic, nokunye. Okokusebenza kwethu kufakazelwe ezinhlelweni eziningi zomhlaba wangempela, okubonisa ukusebenza okuhlukile nezinzuzo zezomnotho, ukusiza amabhizinisi ehlise izindleko zokusebenza ngenkathi ehlangabezana nezinhloso zemvelo.
Njengoba ubuchwepheshe bokuhlanza amanzi buqhubeka nokuvela, izixazululo ezintsha zika-Holly zinikeza amakhasimende emhlabeni wonke imishini esebenza kahle futhi engabizi kakhulu, okunikela ekuthuthukisweni okusimeme kwezimboni zokuchithwa kwamanzi nokuhlanza amanzi. Ngenhlanganisela yobuchwepheshe obusezingeni eliphezulu kanye neminyaka yesipiliyoni sembonini, uHolly uzinikele ekuhlinzekeni ngemishini yokuhlanza amanzi angcolile ethuthuke kakhulu, ukushayela intuthuko embonini kanye nokusimama kwemvelo.
