Kev daws nrog cov txheej txheem tshiab ntawm cov dej khib nyiab furfural kaw cov dej ntws tawm

Nqe lus piav qhia luv:

Cov dej khib nyiab uas tsim los ntawm furfural yog los ntawm Cov organic tsis huv dej, uas muaj cetic acid, furfural thiab cawv, aldehydes, ketones, esters, organic acids thiab ntau yam organic, PH yog 2-3, siab concentration hauv COD, thiab tsis zoo hauv biodegradability .

Cov yam ntxwv thiab kev kho mob ntawm cov dej khib nyiab furfural: Nws muaj acidity muaj zog. Cov dej hauv qab muaj 1.2%~ 2.5%acetic acid, uas yog turbid, khaki, lub teeb sib kis <60%. Ntxiv nrog rau dej thiab kua qaub, nws kuj tseem muaj qhov tsawg heev ntawm furfural, lwm cov kab kawm organic, ketones, thiab lwm yam. COD hauv cov dej khib nyiab yog li 15000 ~ 20000mg/L, BOD yog txog 5000mg/L, SS yog hais txog 250mg/L, thiab qhov kub txog 100 ℃. Yog tias cov dej khib nyiab tsis raug kho thiab tso ncaj qha, cov dej tsis zoo yuav ua rau muaj kev phom sij hnyav thiab cov qauv ntawm ib puag ncig ib puag ncig yuav raug puas tsuaj. Cov txheej txheem kev kho mob feem ntau suav nrog: txheej txheem tshuaj lom neeg, txheej txheem lom neeg (dej qab zib aerobic cov tshuaj tiv thaiv, lim cov tshuaj tiv thaiv aerobic, thiab lwm yam), txheej txheem kev kho mob aerobic (SBR cov tshuaj tiv thaiv, tiv thaiv kev tiv thaiv oxidation), ntawm kev kho aerobic yog lwm qhov tom qab kev kho mob anaerobic txhawm rau kom ntseeg tau tus qauv ntawm cov dej ntws zoo, yog txheej txheem kho tsis tau hauv kev kho cov dej khib nyiab. Txawm li cas los xij, hauv phiaj xwm phiaj xwm ua haujlwm, kev ua haujlwm aerobic yuav nkim sijhawm thiab nyiaj txiag ntau, uas yuav ua rau tus nqi ntawm cov phiaj xwm kho dej, xws li kev ua haujlwm. Yog tias nws tsis zoo, nws yuav ua rau tag nrho cov txheej txheem tsis tuaj yeem ua haujlwm, yog li debug debugging yog qhov tseem ceeb heev rau txoj haujlwm tag nrho, tab sis cov khoom noj muaj txiaj ntsig yog qhov tseem ceeb hauv kev tshem tawm aerobic.

Cov dej khib nyiab uas tsim los ntawm furfural yog los ntawm Cov organic tsis huv dej, uas muaj cetic acid, furfural thiab cawv, aldehydes, ketones, esters, organic acids thiab ntau yam organic, PH yog 2-3, siab concentration hauv COD, thiab tsis zoo hauv biodegradability .

Cov txheej txheem suav hais tias ua kom sov ua kom sov, ua kom lub tshuab ua kom qhuav.

Cov dej khib nyiab vaporized, txhawb siab kom mus txog qhov yuav tsum tau ua, rov ua dua cov furfural thiab cua sov los ntawm cov dej pov tseg kom paub cov dej khib nyiab rov qab siv dua hauv cov txheej txheem tsim khoom. Cov cuab yeej siv qhov program tsis siv neeg los tswj.
