Ucwaningo Lokusebenza Lwe-UV LED Ekuhlanzweni Kwenzalo kanye Ne-Disinfection-Water Purification

Ama-UV-LED, noma ama-ultraviolet light-emitting diode, asephenduke indlela ewusizo yokubulala amagciwane emanzini kule minyaka eyishumi edlule. Izinzuzo zendabuko ze-mercury UV izibani ngaphezu kwamakhemikhali Ukubulawa kwamanzi kwe-UV   amasu asekhona ngama-UV-LED, kodwa futhi aqeda ukushiyeka okuthile.

I-Sterilization Technology

Izicelo eziningi ze Ukuvalwa kwe-UV LED ubuchwepheshe bungatholakala ekuphileni kwansuku zonke. Ngokwesibonelo, isetshenziswa ekudleni, emithini, emanzini nasezinhlelweni zokukhucululwa kwendle. Amakhemikhali, ukushisa, imisebe ye-UV, ne-ozone konke kusetshenziswa njalo Ukuvalwa kwe-UV LED   amasu.

Ngenxa yobulula bawo, amakhemikhali (afana ne-chlorine, i-peroxidase, njll.) avame ukusetshenziswa Ukuvalwa kwe-UV LED ; nokho-ke, zingaba nemiphumela engemihle, njengokushintsha izinga lalokho okuhlosiwe. Ububi bokusebenzisa i-chlorine Ukuvalwa kwe-UV LED ukukhiqizwa kwamakhemikhali anephunga nayingozi.

Amanzi awakwazi ukugcina i-ultraviolet futhi anomthelela omncane ku-ecosystem. Ukwengeza, akubangeli ukumelana ne-bacterial antibiotic. Ngakho, Ukuvalwa kwe-UV LED , esanda kuvela ekukhanyeni njengenye indlela ye-chlorination, ihlanza ngokuphumelelayo ngaphandle kwezinhlanganisela zamakhemikhali.

Amalambu e-UV, njengamalambu e-mercury-vapor aphansi futhi amaphakathi, asetshenziswa kumasu okuvamile okubulala amagciwane e-UV. Lezi zisetshenziswa kumalebhu ebhayoloji nasezikhungweni zezokwelapha ukuze kubulawe amagciwane ezindaweni zokusebenza nemishini. Mayelana nokusebenza kahle kokumuncwa kwe-UV nge-DNA, izibani ze-UV zikhipha i-UV ngobude obuthile begagasi, obufana kakhulu nesiqongo sejiko lokulwa namagciwane.

Imisebe ye-UV ene-frequency engu-365 nm ihlukaniswa njenge-UV-A (320-400 nm), futhi i-UV-A inamandla amancane okulimala kune-UV-C (100-280 nm). I-UV-LED ikhiqiza ukukhanya okunobude obungamaza angama-365 nanometer, obungenabungozi kangako emehlweni nasesikhumbeni somuntu kunesibani esinobude obungama-nanometer angu-254.

Ukwengeza, ngenxa yokuthi i-UV-LED ayinayo i-mercury, ayinayo imiphumela engemihle emvelweni noma kubantu. Isibulala-magciwane esiqaphela imvelo iyi-UV-LED. I-Mercury, eyingozi emvelweni nempilo yomuntu, ikhona ezibanini ze-mercury-vapor.

Izibulala-magciwane ze-UV kufanele zenziwe ukuze zilingane nokwakheka kwezibani, ezivame ukuba zikhulu futhi zithatha indawo enkulu. Ngakho, ngaphandle kokusebenzisa izinto eziyingozi, ezintsha Ukuvalwa kwe-UV LED   imishini esebenzisa amandla aphansi ingadalwa ngezindlela ezihlukahlukene nobukhulu.

Ukuqhathaniswa kwe-UV LED Ne-LED evamile; S

Ama-UV-LED ayakwazi ukuqina, mancane, futhi ayinayo i-mercury kunozakwabo abavamile. Ziphinde zihlale isikhathi eside futhi zithole amandla aphelele ngokushesha. Lezi zinzuzo, ezinezikhathi zokuqalisa cishe ngokushesha kanye namaza angamaza enziwe ngendlela oyifisayo, zinikeza imiklamo ye-UV-LED yesisabela esinamandla amakhulu okuvumelana nezimo.

Ngaphandle kwalezi zinzuzo, izinhlelo zokusebenza ezijwayelekile zereactor ye-UV-LED zigxile kumanethiwekhi amancane, angasebenzi ukwelapha amanzi kamasipala. Ngenxa yobukhulu bawo obumaphakathi, obusuka ku-1 kuye ku-4 mm, ama-UV-LED angabekwa ukuze akhiphe imisebe ezindaweni ezihlukahlukene.

Uma kuqhathaniswa nezibani ezivamile ze-UV, lawa maphethini emisebe agxile kakhulu avumela izinketho eziningi zokuma ngakho-ke, ama-fission reactor ahlukile. Nge- Ukubulawa kwamanzi kwe-UV , Ama-UV-LED abonise ukuthi asebenza kahle okungenani njengezibani ezincishisiwe ze-UV (LPUV) phezu kohlobo olubanzi lwamafrikhwensi alwa namagciwane (isb., 250 –285 nm).

Lezi zinguquko ziyathuthuka unyaka nonyaka. Ukwamukelwa okusabalele kobuchwepheshe bokukhucululwa kwendle obufanele be-UV-LED kuvinjwe izindleko eziphezulu zangaphambili, amandla okukhiphayo ampofu, nokusebenza kahle kwe-facade.

Ngenxa yalokhu, ukusetshenziswa kobuchwepheshe ngokuyinhloko kukhawulelwe endaweni yokusetshenziswa, izinhlelo zokusebenza zeqoqwana ezincane, lapho ukushiyeka kobuchwepheshe kunqotshwa izikhathi zokuchayeka ezinde ukuze kuzuzwe umthamo odingekayo we-UV.

Noma kunjalo, ukwakhiwa kwama-rectors okuqala e-UV-LED anesilinganiso esigcwele angasetshenziswa ezindaweni zokusebenzela zamanzi zikamasipala (WTWs) kwenziwe kwaba nokwenzeka ukuthuthuka okusheshayo kubuchwepheshe be-UV-LED kanye nokwenza kahle kokuklama nokusebenza kweziphehlisi.

Ama-reactor anjalo enziwe ngeshubhu lengilazi eliyikristalu elinama-UV-LED ahlelwe ngochungechunge onqenqemeni lwesilinda, okuvumela ukukhanya kwe-UV ukuthi kungene emanzini ageleza ku-reactor. Ukulawula okushisayo kufezwa ngokukhipha ukushisa okukhiqizwa ama-LED asebenzayo kusetshenziswa uhlelo lokujikeleza okuwuketshezi oluzungeze umkhumbi we-reactor.

I-Biodosimetry

Ukunquma ukuthi ama-UV-LEDs angasetshenziselwa isilinganiso esikhulu Ukubulawa kwamanzi i-UV,   ukuhlolwa okunembile kwe Ukubulawa kwamanzi kwe-UV   ukusebenza kahle kwama-reactor aphelele kuyadingeka. I-Biodosimetry iyindlela yamanje yokuqinisekisa yama-reactors avamile e-UV (kusetshenziswa amalambu e-mercury)

Kulo mongo, ukuhlolwa kokuzwela kwe-microorganism yokuhlolwa kokunye ekuchayekeni kwe-UV ngaphezu kwemithamo ehlukahlukene ene-kinetics yokuvula okulinganiselwe ibizwa ngokuthi i-biodosimetry. Ijika lokuphendula umthamo lama-reactor e-UV ngokuvamile linqunywa ngokuhlolwa kwe-collimated beam kusetshenziswa i-microorganism yamanzi okuhlola.

Umthamo olinganiselwe oncishisiwe (RED) (mJ/cm2) ubalwa kusetshenziswa ijika elilinganiselwe kanye nokuvalwa okulinganiselwe kwe-biodosimeter.

Ijika le-UV-Impendulo Yethamo Lama-reactor

Umzimba onenselelo kufanele ukhuliswe ngendlela efanayo kusukela esitokweni esifanayo sama-microorganisms. Ijika lokuphendula umthamo we-UV lama-reactor liyakhiqizwa ngenxa yokusebenza, futhi libonisa umthamo oncishisiwe wokwenziwa kusebenze kwelogi ngakunye okutholwe ngesilinganiso esigcwele.

Ukwengeza, le ndlela ihlanganisa ukudluliswa kwe-UV (i-UVT) ekubalweni komthamo we-UV, ukumisa amajika okuphendula umthamo we-UV wereactor kumaleveli ahlukahlukene ekhwalithi yamanzi ayizinkomba asekelwe kuphela ku-UVT.

Ngakho-ke, umgomo oyinhloko walo msebenzi bekuwukunquma ukusebenza kwesistimu ye-UV-LED ngokusebenzisa ama-microorganisms okuhlola abambele futhi ayiqhathanise nalawo amalambu e-UV endabuko.

I-Cryptosporidium spp

wakhetha i-Cryptosporidium spp. njengokuphila kwethu okuhlosiwe njengoba i-UV isetshenziswa njalo ezimeni ezinethuba elikhulu lezehlakalo ze-Cryptosporidium. Izinto eziyingozi ze-Cryptosporidium zifaka phakathi ukuba khona kwazo emanzini amthombo, ukumelana ne-chlorine (isikhathi sokuthintana kwe-chlorine okubikiwe). 1000 –10,000 mg min/L), kanye nokuthambekela kokugwema ukuphuza amanzi ahlungiwe ngenxa yobuncane bawo (4 –6 m).

Ukwelashwa kwe-UV okungasasebenzi kwe-Cryptosporidium parvum kungu-0.16 cm2/MJ, okungaphansi kakhulu kokungashintshi okuhambisanayo kwe-chlorine yamahhala.
