Peb tau nruab peb lub tshuab tshem tawm cov tshuaj fluoride tob rau ib lub Hoobkas tsim cov wafer / lub hnub ci hlwb
Thaum pib lub Tsib Hlis, kev lag luam photovoltaic tau ua ib kauj ruam tseem ceeb hauv kev txhim kho cov kev coj ua kom ruaj khov. Lub Hoobkas tsim cov wafer hnub ci thiab lub hnub ci cell hauv tebchaws tau ua tiav kev teeb tsa lub tshuab tshem tawm fluoride tob tshaj plaws. Qhov kev teeb tsa no yog qhov tseem ceeb hauv kev ua kom tau raws li qhov xav tau ntawm kev kho dej khib nyiab photovoltaic zoo.
Kev nthuav dav sai ntawm kev lag luam photovoltaic tau ua rau muaj kev nce ntxiv ntawm kev tsim cov dej khib nyiab photovoltaic, uas yuav tsum tau siv cov txheej txheem kho mob siab heev. Kev kho cov dej khib nyiab no yog qhov tseem ceeb kom ntseeg tau tias nws ua tau raws li cov qauv ib puag ncig ua ntej tso tawm.
Cov dej khib nyiab photovoltaic feem ntau muaj cov pa phem xws li hmoov silicon, silicon carbide, polyethylene glycol, fluoride ions, acids thiab bases. Thaum silicon rods thiab wafers raug txiav, zom, txiav tawm, zom, corroded, thiab polished, cov kua pov tseg ntxiv thiab cov dej khib nyiab huv. Polysilicon wastewater, organic silicon wastewater, silicon wafer cleaning, mortar recycling wastewater, txiav thiab polishing wastewater kuj raug hu ua photovoltaic wastewater. Qhov muaj cov photovoltaic wastewater no yuav ua rau muaj kuab paug rau ib puag ncig, thiab tseem yuav txwv tsis pub muaj kev txhim kho ntawm hom kev lag luam no. Yog li yuav tsum kho hom photovoltaic wastewater no li cas?
Cov txheej txheem kho dej phwj uas muaj fluorine ntau hauv photovoltaic feem ntau muaj peb theem: kev kho ua ntej, kev kho tseem ceeb thiab kev kho tom qab. Theem kev kho ua ntej yog tshem tawm cov khoom tawg thiab cov khoom tsis huv hauv cov dej phwj kom muab cov dej zoo rau theem kev kho tseem ceeb; theem kev kho tseem ceeb yog ua cov haujlwm xws li kev nqus, kev pauv lossis kev sib cais ntawm cov fluoride ions; theem kev kho tom qab yog kho cov dej phwj uas tau kho lawm. Cov dej khib nyiab raug tua kab mob, tshem cov ntsev thiab lwm yam haujlwm raug ua kom tau raws li qhov yuav tsum tau ua rau kev tso tawm lossis rov siv dua.
Qhov kev siv lub tshuab kho mob siab heev no qhia txog kev cog lus ntawm kev lag luam rau kev saib xyuas ib puag ncig thiab kev ruaj khov. Nws sawv cev rau txoj hauv kev ua ntej los daws cov teeb meem ib puag ncig uas cuam tshuam nrog kev loj hlob sai ntawm kev lag luam photovoltaic.
Raws li qhov kev thov rau lub zog hnub ci txuas ntxiv mus, kev teeb tsa cov thev naus laus zis kho dej khib nyiab tshiab yog qhov tseem ceeb rau kev txo qis qhov cuam tshuam ntawm kev lag luam. Kev siv lub tshuab tshem tawm cov fluoride tob tau teeb tsa tus qauv rau kev tiv thaiv ib puag ncig hauv kev lag luam photovoltaic thiab tau dhau los ua tus qauv rau kev txhim kho kom ruaj khov hauv kev siv hluav taws xob rov ua dua tshiab.
