Dab tsi yog Ultrasonic Homogenizer Rau Biodegradation

Ultrasonic biodegradation thev naus laus zis, nrog rau nws qhov zoo ntawm kev ua tus phooj ywg zoo ib puag ncig, kev ua haujlwm zoo, thiab muaj peev xwm degrading nyuaj - los - kho cov tshuaj, muaj cov kev cia siab dav hauv kev tiv thaiv ib puag ncig, khoom noj khoom haus, thiab biomedicine. Txawm li cas los xij, tam sim no nws ntsib cov teeb meem xws li kev siv hluav taws xob thiab scalability. Raws li thev naus laus zis txuas ntxiv ua kom zoo, nws cov kev lag luam thiab kev lag luam daim ntawv thov muaj peev xwm yuav maj mam tso tawm. Txhawm rau kom ua tiav daim ntawv thov loj -, cov thev naus laus zis no tseem yuav tsum tau kov yeej ntau lub fwj: Ua ntej, kev siv hluav taws xob siab; Kev ua ultrasonic tam sim no suav nrog kev poob qis, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov kev lag luam uas cov nqi khiav lag luam siab. Qhov thib ob, tsis muaj cov qauv kev sib koom ua ke; tsis xws li ultrasonic zaus thiab lub zog tsis yog tus qauv rau cov xwm txheej sib txawv, ua rau muaj qhov sib txawv tseem ceeb hauv kev ua haujlwm. Txawm li cas los xij, cov teeb meem no tuaj yeem daws tau los ntawm kev ua kom zoo dua qub, xws li kev txhim kho siab -cov khoom siv hluav taws xob zoo los txhim kho lub zog hloov hluav taws xob, tsim kom muaj cov txheej txheem kev sib txawv rau cov xwm txheej sib txawv los ntawm cov ntaub ntawv loj, thiab tsim cov khoom siv modular kom hloov mus rau qhov loj - nplai ua cov kev xav tau. Raws li thev naus laus zis loj hlob tuaj, nws cov nqi thov yuav txo qis, thiab daim ntawv thov scenarios yuav nthuav dav ntxiv, ua rau nws qhov kev cia siab tag nrho zoo heev.

 

I. Txoj Cai Ua Haujlwm ntawm Ultrasonic Biodegradation

Ultrasonic homogenizer yog lub hauv paus: Thaum ultrasound propagates hauv cov kua, nws generates countless me npuas (cavitation npuas).

Kev ua npuas hnyav: Cov npuas cavitation nthuav dav sai thiab tom qab ntawd tawg tam sim ntawd, ua kom muaj qhov kub thiab txias hauv cheeb tsam (txog li ntau txhiab degrees Celsius thiab ntau pua ntawm cua) thiab muaj zog poob siab.

Degradation ntawm cov pa phem: Nyob rau hauv qhov kub thiab txias, muaj zog oxidizing tshuaj xws li hydroxyl radicals yog generated. Nyob rau tib lub sijhawm, lub zog poob siab tsis ua rau cov tshuaj lom neeg ua paug, thaum kawg decomposing loj molecular pollutants rau hauv me me, tsis muaj teeb meem molecules (xws li carbon dioxide thiab dej).

 

II. Cov laj thawj tseem ceeb rau kev siv cov cuab yeej Ultrasonic

High degradation efficiency: Lub zog oxidation thiab mechanical cuam tshuam ntawm cavitation tuaj yeem decompose cov pa phem recalcitrant sai (xws li cov tshuaj tua kab thiab cov dej khib nyiab hauv kev lag luam).

 

Tsis muaj kuab paug thib ob: Tsis xav tau cov tshuaj lom neeg; degradation tsuas yog nyob rau ntawm lub cev thiab cov txheej txheem tshuaj, tsis txhob muaj kuab paug tshiab los ntawm cov tshuaj tua kab.

 

Kev siv dav: Nws tuaj yeem kho ntau yam organic thiab inorganic pollutants hauv cov kua thiab tsis txwv los ntawm cov pa phem concentration, ua rau nws haum rau ntau yam xwm txheej xws li kev kho dej khib nyiab thiab zaub mov purification.

 

Kev Ua Haujlwm Yooj Yim: Cov cuab yeej ua haujlwm ruaj khov, tsis tas yuav tsum muaj kev saib xyuas nyuaj, thiab tuaj yeem siv ua ke nrog cov txheej txheem kho mob uas twb muaj lawm, txo cov nqi rov qab.

 

Dab tsi yog qee qhov kev thov ntawm ultrasonic biodegradation technology?

Ultrasonic biodegradation technology, nrog nws cov cim cavitation nyhuv thiab oxidation yam ntxwv, muaj cov tswv yim siv nyob rau hauv ntau yam xws li kev kho dej khib nyiab, sludge pov tseg, lom thwmsim, zaub mov, thiab kev kho mob daim ntawv thov. Cov hauv qab no yog cov piv txwv tshwj xeeb: Industrial Wastewater Treatment

Electronic Component Wastewater: Ib lub tuam txhab tsim khoom siv hluav taws xob tau txais cov txheej txheem ua ke ntawm "siab-kev ua haujlwm zoo + kev ua haujlwm tsis zoo thiab kev hloov kho + qib siab oxidation (ozone) + MBR + tshuaj tua kab mob ultraviolet." Tom qab qhia ultrasonic- pab kev kho mob, COD tshem tawm tus nqi ntawm cov dej khib nyiab mus txog 93%, thiab qhov kawg ntawm cov dej ntws zoo tau ntsib thawj tus qauv tawm hauv chav kawm, txhim kho cov txiaj ntsig zoo ntawm cov txheej txheem qub.

 

Electroplating hnyav hlau khib nyiab: Rau electroplating khib nyiab uas muaj 4000 × 10⁻⁶ mol / L ntawm npib tsib xee, kev kho ultrasonic ua tiav cov nickel ion tshem tawm tus nqi siab tshaj 99%. Rau cov dej khib nyiab uas muaj 1000 × 10⁻⁶ mol / L ntawm tooj liab, kev kho ultrasonic ua tiav cov tooj liab ion tshem tawm ntawm 99.8%. Lub hauv paus ntsiab lus tseem ceeb yog txhawm rau ua kom cov hlau hnyav hnyav los ntawm kev co, ua kom yooj yim los nag thiab pom tom qab.

 

Dyeing thiab tanning cov dej khib nyiab: Lub Hoobkas dyeing siv 40kHz ultrasonic- pab Fenton oxidation thev naus laus zis kom tshem tawm cov khoom qias neeg tsis zoo los ntawm cov dej khib nyiab, ua kom tau raws li cov qauv kev tawm hauv lub tebchaws. Cov kev sim ntxiv tau pom tias pretreatment ntawm tanning cov dej khib nyiab nrog ultrasound ntawm lub suab siv ntawm 1.47 W / cm² thiab zaus ntawm 24kHz, ua ke nrog coagulation thiab sedimentation, nce COD tshem tawm tus nqi ntau dua 10%, mus txog qhov siab tshaj plaws ntawm 73.2%, piv rau yooj yim coagulation thiab sedimentation.

Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Kev Tshawb Fawb Txog Kev Tshawb Fawb

 

Biomolecular Processing: Hauv kev tshawb fawb biochemical, ultrasound tuaj yeem ua kom DNA tawg thiab degradation. Cov cuab yeej no ua tau raws li qhov xav tau los txo cov qauv DNA loj hauv kev tshawb fawb bioinformatics thiab tseem tuaj yeem siv rau hauv kev saib xyuas ib puag ncig los txheeb xyuas dej DNA txhawm rau nrhiav cov pa phem. Nyob rau tib lub sijhawm, nws tuaj yeem cuam tshuam cov protein complexes, pab hauv kev tshuaj xyuas cov tshuaj neeg sib tw molecules. Nyob rau hauv cov tshuaj forensic thiab soj ntsuam kuaj mob, ultrasound kuj yuav pab tau nyob rau hauv lub extraction ntawm nucleic acids los ntawm cov qauv, kev txhim kho kev tshawb nrhiav efficiency thiab purity.

Khoom noj khoom haus thiab kev kho mob ntsig txog teb

 

Kev puas tsuaj ntawm cov tshuaj tua kab mob hauv cov khoom noj: Cov tshuaj tua kab mob xws li penicillin hauv cov mis nyuj muaj qhov kub thiab txias, thiab cov cua sov ua kom tsis muaj menyuam tsis txaus los tshem tawm tag nrho. Ib pab neeg tshawb fawb ntawm Xihua University tau ua qhov kev sim ntawm kev degradation ntawm penicillin hauv cov mis nyuj. Nyob rau hauv cov xwm txheej ntawm 25℃thiab pH 7, mis nyuj uas muaj penicillin tau kho nrog 150W ultrasound rau 35 feeb. Qhov kawg penicillin residue nyob rau hauv cov mis nyuj yog tsawg dua 1 ug / L, ua tau raws li cov qauv kev nyab xeeb. Txoj kev no zam kev puas tsuaj rau cov kua mis zoo uas tshwm sim los ntawm siab - kub lossis tshuaj kho mob thiab muab cov kev daws teeb meem rau kev kho cov tshuaj tua kab mob hauv cov khoom siv mis nyuj.

 

Kev pab kho mob kom tsis muaj menyuam: Ultrasound tuaj yeem rhuav tshem cov cell membranes thiab cell phab ntsa ntawm cov kab mob, thiab tuaj yeem pab ua kom tsis muaj menyuam ntawm cov khoom siv kho mob hauv kev kho mob. Piv txwv li, rau qee qhov siab -kub- cov cuab yeej ntsuas qhov ntsuas siab, ultrasound tuaj yeem nkag mus rau hauv cov kab mob kom tua cov kab mob, txo qhov kev pheej hmoo ntawm kev sib kis - kab mob thaum cov txheej txheem kho mob. Nws tseem tuaj yeem ua ke nrog lwm txoj kev ua kom tsis muaj menyuam txhawm rau txhim kho cov nyhuv.
