Bar cov ntxaij vab tshaus yog thawj chav pretreatment hauv cov chaw kho dej khib nyiab, siv los cuam tshuam thiab tshem tawm cov khoom tsis zoo ntawm cov dej khib nyiab, tiv thaiv cov khoom siv kho mob hauv qab.
Core Functions thiab Roles
Cov dej khib nyiab muaj cov khib nyiab loj xws li textiles, ntawv, plastics, thiab hlau, nrog rau pob zeb. Yog tias cov impurities nkag mus rau theem tom ntej kev kho mob, lawv tuaj yeem txhaws cov kav dej, cov twj tso kua mis thiab lwm yam khoom siv hauv qab, thiab nce cov khoom siv tsis tsim nyog hnav thiab tu cov nqi. Bar cov ntxaij vab tshaus yog tsim los cais cov impurities ua ntej, txo cov kev pheej hmoo cuam tshuam nrog kev kho mob tom ntej. Lawv lub luag haujlwm tseem ceeb yog ntau dua txog kev tiv thaiv cov chaw qis tshaj qhov ua tau zoo thiab tshem tawm tag nrho cov khoom muaj kuab paug los ntawm cov neeg muaj zog.
Kev faib tawm
Raws li txoj kev tu thiab bar qhov sib nrug, cov ntxaij vab tshaus bar tuaj yeem raug cais raws li hauv qab no:
● Manually Cleaned Bar Screens:Feem ntau ua los ntawm cov hlau puag ncig lossis cov duab plaub, lawv tuaj yeem ntsia tau ntsug lossis ntawm lub kaum sab xis (60℃-80℃rau kab rov tav) kom yooj yim tu. Lawv feem ntau yog siv rau kev sib tshuam bypass daim ntawv thov thiab tsuas yog tsim rau cov chaw kho mob me me xwb.
● Mechanically Cleaned Bar Screens:Qhov no tam sim no yog qhov kev xaiv tseem ceeb rau loj - cov xwm txheej kho mob. Qhov sib nrug yog feem ntau 1/2 nti rau 1 1/2 nti. Lawv tau txais kev ntxuav thiab tsim nyog rau kev lag luam txuas ntxiv / kev kho dej khib nyiab hauv nroog. Qee cov khoom tuaj yeem ua tiav kev tswj hwm tsis siv neeg, nrog lub tswb tsis siv neeg thiab kaw thaum muaj kev thaiv.
● Fine Bar Screens:Qhov sib nrug me me yog 1/4 nti lossis me dua, nrog qhov tsawg kawg nkaus ntawm 0.5mm. Lawv feem ntau siv ua ke nrog ntxhib bar cov ntxaij vab tshaus los cuam tshuam cov impurities finer, ua tau raws li qhov yuav tsum tau ua ua ntej ntawm kev kho mob siab heev lossis membrane bioreactor (MBR) systems.
Raws li qhov sib txawv ntawm qhov loj tshaj mus rau qhov tsawg tshaj plaws, lawv tuaj yeem muab faib ntxiv rau hauv:
● Cov ntxaij vab tshaus: qhov khoob 1.5-4 ntiv tes, feem ntau ntxuav manually.
● Coarse cov ntxaij vab tshaus: qhov khoob 0.5-1.5 ntiv tes, feem ntau ntxuav txhua yam.
● Cov ntxaij vab tshaus zoo: qhov khoob tsawg dua lossis sib npaug li 0.25 ntiv tes, siv rau kev pom zoo.
