Txhawm rau kom daws tau cov teeb meem zoo ntawm cov dej phwj tuaj, kev siv theem nrab thiab rov siv dua, kev siv tshuaj kho dej ozone ua lub luag haujlwm tseem ceeb hauv kev kho dej. Ozone tshem tawm cov pa phem xws li xim, tsw thiab phenolic chlorine hauv dej phwj tuaj, nce cov pa oxygen hauv dej, thiab txhim kho cov dej tsis zoo.
Cov dej phwj hauv tsev muaj cov theem siab ntau ntawm cov organic, xws li ammonia, sulfur, nitrogen, thiab lwm yam. Cov tshuaj no muaj cov noob nquag thiab nquag muaj tshuaj lom neeg. Ozone yog ib qho muaj zog uas muaj oxidant oxidizes ntau yam ntawm cov organic thiab inorganic. Siv cov yam ntxwv ntawm kev muaj zog oxidation ntawm ozone, txhaj ib co concentration ntawm ozone rau hauv cov dej phwj, tuaj yeem tshem tawm qhov tsw thiab deodorizing. Tom qab deodorization, ozone yog yooj yim decomposed hauv dej, thiab nws tsis ua rau muaj kuab paug lwm yam. Nws tseem tuaj yeem tiv thaiv qhov rov ua kom tsw tsw. Ozone deodorization ua rau kom muaj qhov oxygen ntau ntau, ua rau thaj chaw muaj pa oxygen thiab ua rau muaj cov ntxhiab tsw tsis zoo. Nws yog qhov nyuaj rau tsim cov ntxhiab tsw hauv qhov chaw aerobic.
Thaum cov dej phwj raug siv los siv cov dej rov qab, yog tias cov dej phwj tawm mus pov tseg muaj cov chroma siab, piv txwv li, yog tias cov xim hauv dej yog siab tshaj 30 degrees, dej yuav tsum tau txiav txim siab, txiav txim siab, thiab txiav txim siab. Nyob rau tam sim no, cov txheej txheem ib txwm suav nrog kev txiav txim siab thiab kev zeem, xuab zeb pom, adsorption decolorization, thiab ozone oxidation.
Cov txheej txheem sib xyaw ua ke nrog cov lim dej thiab cov xuab zeb pom kev tsis tuaj yeem ua tiav cov qauv dej kom tau zoo, thiab cov dej ntws sai sai yuav xav tau kev kho mob thib ob. Adsorption decolorization muaj kev xaiv decolorization, xav tau hloov ntau zaus, thiab tus nqi yuav siab.
Ozone yog oxidant muaj zog heev, muaj qhov muaj peev xwm hloov tau mus rau chromaticity, high decolorization efficiency, thiab muaj zog oxidative decomposition zoo rau cov xim organic. Cov teeb meem xim dawb yog feem ntau muaj cov tshuaj polycyclic organic muaj ib daim ntawv cog lus tsis muaj txhij txhua. Thaum kho nrog ozone, cov tshuaj sib tov tsis haum yuav qhib rau kev sib khi, thiaj li ua rau dej ntshiab. Tom qab kho mob ozone, cov chroma tuaj yeem raug txo kom tsawg dua 1 degree. Ozone ua lub luag haujlwm tseem ceeb hauv kev siv cov dej rov qab.
