Txhim Kho Kev Kho Mob Biological

Cov thev naus laus zis ultrasonic tuaj yeem txhim kho qhov sib txuas ntawm cov khoom khov-kua, txhim kho cov roj theem hloov pauv thiab cov khoom noj khoom haus hloov pauv, thiab txhawb kev kho mob biological. o. Cov kws tshawb fawb Schlafer siv cov ultrasound zog qis los kho cov dej khib nyiab hauv kev lag luam brewery, thiab lub bioreactor kho tau zoo. Hauv kev sim, lub zog ultrasonic yog 0.3 w / l thiab zaus yog 25 kHz. tom qab kev kho mob ultrasonic, qhov concentration floc tau nce ntxiv los ntawm 0.12 g / l txog 0.4 g / l, thiab kev kho mob tau nce ntxiv 50%.

Kev Kho Mob Ntawm Cov Cawv Dub Ntawm Kev Ua Ntawv

Cov dej cawv dub yog cov kua pov tseg uas muaj lignin thiab humic acid. Kev kho nws yog ib qho teeb meem nyuaj. Peb lub tuam txhab siv pfs/h2o2 thiab kev kho ultrasonic. Kev sib piv pom tias tus nqi tshem tawm ntawm CODCr nce ntxiv li 13%, tus nqi tshem tawm ntawm PFS txo qis 14%, thiab tus nqi tshem tawm ntawm H2O2 txo qis 50-80%. Kev siv tshuab ultrasonic thiab kev siv tshuab oxidation tau siv los kho cov dej cawv dub ntawm kev ua ntawv.

Kev rhuav tshem cov khoom siv organic siv Ultrasonic lub zog lub cev teb

Cov teb zog lub cev siv dav hauv kev kho dej. Kev sib xyaw ua ke ntawm ultrasound nrog lwm cov teb zog lub cev (lub teeb teb, hluav taws xob teb, sib nqus teb) yog ib qho ntawm cov lus qhia tshawb fawb. Kev sib xyaw ua ke ntawm ultrasound thiab lub teeb ultraviolet yog siv los kho cov dej phwj hauv tsev thiab rhuav tshem cov organic teeb meem. Cov kev tshawb fawb tau qhia tias muaj peb lub luag haujlwm hauv cov txheej txheem rhuav tshem: ultraviolet decomposition, ultrasonic oxidative decomposition ntawm hydroxyl pawg, thiab ultraviolet decomposition ntawm huab cua kom rhuav tshem ozone.
