Ultrasonic dej phwj kho
Cov peev txheej dej ntawm ib tus neeg hauv Suav teb tsawg tsawg thiab qhov chaw faib khoom tsis sib npaug. Nrog rau acceleration ntawm nroog thiab industrialization nyob rau hauv Tuam Tshoj, qhov kev thov sib txawv ntawm cov dej siv kuj nce. Tom qab cov dej phwj tuaj kho, nws tuaj yeem rov ua dua tshiab kom txo tau cov khoom siv dej hauv peb lub tebchaws. Kev kho dej siv thev naus laus zis siv cov txuj ci tseem ceeb los ntxuav cov dej phwj tuaj yeem siv txuas ntxiv, yog li kev kho dej phwj yog qhov tseem ceeb heev. Ultrasound plays lub luag haujlwm tseem ceeb hauv kev kho cov dej phwj tuaj / dej khib nyiab.
Ultrasonic dej phwj kho yog dab tsi?
Siv cov nyhuv cavitation ntawm ultrasonic degrade teeb meem organic teeb meem nyob rau hauv dej, thiaj li kom paub lub hom phiaj ntawm ultrasonic dej phwj kho mob.
Vim li cas siv ultrasonic dej phwj kho?
1. Ua ntej tshaj plaws, lub zog loj, thiab nws lub zog loj dua li cov suab tsis zoo ib yam.
2. Cov txheej txheem kev kho dej khib nyiab ib txwm muaj xws li cov txheej txheem lom neeg, txoj kev siv lub cev thiab cov txheej txheem tshuaj. Txawm li cas los xij, cov txheej txheem lom neeg suav nrog cov txheej txheem anaerobic muaj lub sijhawm kho mob ntev thiab nyuaj los txo lawv cov tshuaj lom, ua rau muaj ntau yam khoom lom. Cov txheej txheem lub cev muaj xws li electrocoagulation, adsorption, membrane sib cais thiab flocculation, thiab cov qauv ntawm lub cev no feem ntau tsis zoo. Thaum cov txheej txheem tshuaj xws li photocatalytic degradation thiab ozone oxidation tsis coj cov pa phem thib ob, lub sijhawm kho mob kuj ntev thiab tus nqi kuj tseem siab. Ultrasonic wastewater kho tshuab yog ceev, npaum thiab tsis muaj pa phem thib ob. Cov nyhuv cavitation ntawm ultrasonic tsis muaj peev xwm degrade teeb meem organic tshuaj nyob rau hauv dej, yog li realizing lub hom phiaj ntawm ultrasonic organic wastewater kho. Nyob rau hauv cov txheej txheem ntawm cov organic wastewater kho, lub cavitation ntawm ultrasonic tsis muaj zog muaj peev xwm degrade organic teeb meem, thiab tus nqi degradation yog ceev heev. Nws tuaj yeem cuam tshuam nrog cov teeb meem organic los ntawm oxidation cov tshuaj tiv thaiv nrog hydrogen radicals, thiab tuaj yeem hloov cov teeb meem organic hauv dej rau hauv inorganic ions los yog cov teeb meem organic uas tsis muaj tshuaj lom thiab degradable dua li cov khoom qub qub. Yog li ntawd, cov organic kuab paug uas nyuaj rau biodegraded nyob rau hauv cov tsoos organic wastewater kho yuav degraded los ntawm ultrasonic cavitation, thiab cov dej khib nyiab generated los ntawm lub ultrasonic tu tshuab yuav kuj muaj ntau impurities, roj thiab lwm yam tshuaj, uas yuav tsum tau kev kho mob ntxiv.
Yuav ua li cas kho ultrasonic dej phwj?
Tom qab biodegradation, tus pilot-scale voj voog tester yog siv los rhuav cov phab ntsa ntawm cov kab mob hauv cov dej phwj tuaj los ntawm ultrasonic cavitation, uas tuaj yeem txhim kho cov lim-nias kev ua haujlwm ntawm cov dej phwj tuaj thiab txo cov dej ntawm cov sludge tom qab lim-nias.
