Daim ntawv thov kev tshawb fawb ntawm UV LED hauv Sterilization Thiab Disinfection-Dej purification

UV-LEDs, lossis ultraviolet lub teeb-emitting diodes, tau dhau los ua cov txheej txheem siv tshuaj tua kab mob hauv dej hauv kaum xyoo dhau los. Qhov zoo ntawm cov tsoos mercury UV teeb tshaj tshuaj UV dej   Cov tswv yim tseem muaj nrog UV-LEDs, tab sis lawv kuj ua rau qee qhov tsis zoo.

Sterilization Technology

Ntau yam kev siv ntawm UV LED Sterilization thev naus laus zis tuaj yeem pom hauv lub neej niaj hnub. Piv txwv li, nws yog siv rau hauv cov khoom noj, tshuaj, dej, thiab cov kav dej phwj tuaj. Cov tshuaj, tshav kub, UV hluav taws xob, thiab ozone txhua zaus siv UV LED Sterilization   cov txheej txheem.

Vim lawv qhov yooj yim, cov tshuaj (xws li chlorine, peroxidase, thiab lwm yam) feem ntau siv rau UV LED Sterilization ; Txawm li cas los xij, lawv yuav muaj qhov tsis zoo, xws li hloov lub hom phiaj zoo. Qhov tsis zoo ntawm kev siv tshuaj chlorine rau UV LED Sterilization yog kev tsim cov tshuaj tsw qab thiab biohazardous chemicals.

Dej tsis tuaj yeem khaws ultraviolet thiab tsis tshua muaj kev cuam tshuam rau ecosystem. Tsis tas li ntawd, nws tsis ua rau cov kab mob tua kab mob. Yog li, UV LED Sterilization , uas tsis ntev los no tau tshwm sim nyob rau hauv lub tsom teeb raws li ib tug chlorination lwm txoj, zoo cleans tsis muaj tshuaj sib txuas.

UV teeb, xws li qis thiab nruab nrab mercury-vapor teeb, yog siv nyob rau hauv cov txheej txheem UV sterilizing. Cov no yog siv rau hauv cov chaw sim tshuaj lom neeg thiab cov chaw kho mob los tua kab mob hauv chaw ua haujlwm thiab khoom siv. Hais txog kev ua haujlwm ntawm UV nqus los ntawm DNA, UV teeb emit UV ntawm ib lub wavelength tshwj xeeb, uas zoo sib xws rau cov peaks ntawm kev tiv thaiv kab mob microbial.

UV hluav taws xob nrog lub zaus ntawm 365 nm yog categorized li UV-A (320-400 nm), thiab UV-A muaj peev xwm ua rau kev puas tsuaj tsawg dua li UV-C (100-280 nm). UV-LED tsim lub teeb nrog lub wavelength ntawm 365 nanometers, uas tsis tshua muaj teeb meem rau tib neeg lub qhov muag thiab tawv nqaij tshaj lub teeb nrog 254-nanometer wavelength.

Tsis tas li ntawd, vim UV-LED tsis muaj mercury, nws tsis muaj qhov tsis zoo rau ib puag ncig lossis tib neeg. Ib puag ncig paub txog kev ua kom tsis muaj menyuam yog UV-LED. Mercury, uas yog teeb meem rau ib puag ncig thiab tib neeg kev noj qab haus huv, muaj nyob rau hauv mercury-vapor teeb.

UV sterilizers yuav tsum tau ua kom haum rau cov duab ntawm lub teeb, uas feem ntau loj thiab nyob hauv ntau chav. Yog li, tsis siv cov khoom siv phom sij, tshiab UV LED Sterilization   cov cuab yeej siv hluav taws xob tsawg tuaj yeem tsim tau ntau yam duab thiab ntau thiab tsawg.

Kev sib piv ntawm UV LED nrog cov pa LED; S

UV-LEDs yog qhov muaj zog dua, me dua, thiab tsis muaj mercury ntau dua li lawv cov khoom sib xws. Lawv kuj kav ntev dua thiab ua tiav tag nrho lub zog sai dua. Cov txiaj ntsig no, nrog rau lub sijhawm pib yuav luag tam sim ntawd thiab cov kev hloov pauv hloov tau, muab UV-LED reactor tsim nrog kev tsim qauv zoo.

Txawm hais tias cov txiaj ntsig zoo li no, cov ntawv thov siv UV-LED reactor tau tsom mus rau cov tes hauj lwm me me, uas tsis zoo rau kev kho dej hauv nroog. Vim lawv qhov loj me me, uas yog li ntawm 1 txog 4 hli, UV-LEDs tuaj yeem muab tso rau emit hluav taws xob nyob rau hauv ntau yam kev qhia.

Piv nrog rau cov teeb pom kev UV, cov qauv hluav taws xob tsom mus rau ntau qhov tso cai rau ntau txoj kev xaiv thiab yog li ntawd, tshwj xeeb fission reactors. Ntaus UV dej , UV-LEDs tau pom tias tsawg kawg yog qhov ua tau zoo li txo qis UV (LPUV) teeb hla qhov dav dav ntawm kev tiv thaiv kab mob microbial frequencies (xws li, 250 –285 nm).

Cov kev hloov pauv no tau txhim kho txhua xyoo. Kev siv dav dav ntawm UV-LED cov cuab yeej ua kom huv huv tau raug txwv los ntawm cov nqi siab tshaj, cov khoom siv tsis zoo, thiab kev ua haujlwm tsis zoo.

Raws li qhov tshwm sim, kev siv thev naus laus zis feem ntau tau txwv rau qhov taw qhia ntawm kev siv, cov ntawv thov me me batch, qhov twg cov kev tsis txaus ntawm cov thev naus laus zis tau kov yeej los ntawm lub sijhawm ntev ntev kom ua tiav cov tshuaj UV tsim nyog.

Txawm li cas los xij, kev tsim cov thawj puv-scale UV-LED reactors uas yuav siv tau ntawm cov dej hauv nroog (WTWs) tau ua tiav los ntawm kev nce qib sai hauv UV-LED thev naus laus zis thiab kev ua kom zoo ntawm cov reactors tsim thiab kev ua tau zoo.

Cov reactors zoo li no yog ua los ntawm cov iav siv lead ua iav raj nrog UV-LEDs teeb tsa nyob rau hauv ib tug series raws li lub tog raj kheej ntug, uas tso cai rau UV teeb nkag mus rau hauv cov dej ntws los ntawm lub reactor. Thermal tswj yog ua tiav los ntawm dissipating lub tshav kub uas ua los ntawm cov kev khiav hauj lwm LEDs siv ib tug dej ncig system nyob ib ncig ntawm lub reactor hlab ntsha.

Biodosimetry

Txhawm rau txiav txim siab seb UV-LED tuaj yeem siv rau qhov loj UV dej,   kev ntsuam xyuas meej ntawm cov UV dej   Yuav tsum muaj kev ua haujlwm ntawm tag nrho-scale reactors. Biodosimetry yog tam sim no validation txoj kev rau cov pa UV reactors (siv mercury teeb)

Nyob rau hauv cov ntsiab lus no, qhov kev ntsuam xyuas ntawm ib tug surrogate test microorganism qhov rhiab heev rau UV raug ntau npaum li cas nrog calibrated activation kinetics hu ua biodosimetry. Qhov koob tshuaj tiv thaiv kab mob rau UV reactors feem ntau txiav txim siab los ntawm kev sib tsoo beam sim siv cov dej ntsuas cov kab mob.

Qhov txo qis tus txheeb ze koob tshuaj (RED) (mJ / cm2) yog suav nrog kev ntsuas nkhaus thiab ntsuas qhov tsis ua haujlwm ntawm biodosimeter.

UV Dose-Response Curve Rau Cov Reactors

Cov kab mob sib tw yuav tsum tau loj hlob zoo ib yam los ntawm tib cov khoom lag luam ntawm cov kab mob. UV koob tshuaj tiv thaiv kab mob rau cov reactors yog tsim los ntawm kev ua haujlwm, thiab nws qhia txog kev txo qis rau txhua lub cav inactivation tau txais ntawm tag nrho cov nplai.

Tsis tas li ntawd, txoj hauv kev suav nrog UV transmittance (UVT) hauv kev suav cov koob tshuaj UV, ua qauv rau cov reactor's UV dose-response curves rau ntau qhov qhia txog cov dej zoo raws li qhov tseeb ntawm UVT.

Yog li ntawd, lub hom phiaj tseem ceeb ntawm txoj haujlwm no yog los txiav txim siab txog UV-LED qhov kev ua tau zoo los ntawm kev siv cov kab mob hloov pauv thiab muab piv rau cov teeb pom kev ntawm UV teeb.

Cryptosporidium spp

xaiv Cryptosporidium spp. raws li peb lub hom phiaj kab mob txij li UV tau nquag siv rau hauv cov xwm txheej uas muaj qhov tshwm sim ntau dua ntawm Cryptosporidium. Cov xwm txheej txaus ntshai rau Cryptosporidium suav nrog lawv qhov muaj nyob hauv cov dej, tiv thaiv cov tshuaj chlorine (qhia cov tshuaj chlorine tiv tauj ntev ntawm 1000 –10,000 mg min / L), thiab propensity kom tsis txhob haus cov dej lim dej vim lawv qhov me me (4 –6 m).

Kev kho UV tsis ua haujlwm rau Cryptosporidium parvum yog 0.16 cm2 / MJ, uas yog qhov tsawg dua li qhov sib thooj rau cov tshuaj dawb dawb.
