Dealing nrog cov txheej txheem tshiab ntawm furfural pov tseg dej kaw evaporation ncig
National invention patent
Cov yam ntxwv thiab txoj kev kho ntawm furfural wastewater: Nws muaj zog acidity. Cov dej khib nyiab hauv qab muaj 1.2% ~ 2.5% acetic acid, uas yog turbid, khaki, lub teeb transmittance <60%. Ntxiv rau cov dej thiab acetic acid, nws kuj muaj ib qho me me ntawm furfural, lwm cov kab organic acids, ketones, thiab lwm yam COD hauv cov dej khib nyiab yog li 15000 ~ 20000mg / L, BOD yog li 5000mg / L, SS yog hais txog. 250mg / L, thiab qhov kub yog txog 100 ℃. Yog tias cov dej khib nyiab tsis raug kho thiab tso tawm ncaj qha, cov dej tsis zoo yuav ua rau muaj kuab paug loj thiab cov qauv ntawm ib puag ncig ecological yuav raug puas tsuaj. Cov kev kho mob dav dav feem ntau suav nrog: chemical method, biological method (sab saum toj aerobic cov tshuaj tiv thaiv, lim aerobic cov tshuaj tiv thaiv, thiab lwm yam), cov txheej txheem kho aerobic (SBR cov tshuaj tiv thaiv, tiv tauj oxidation cov tshuaj tiv thaiv), cov kev kho mob aerobic yog lwm qhov tom qab kev kho mob anaerobic Kev kho mob, Txhawm rau kom ntseeg tau tus qauv ntawm cov dej tsis zoo, nws yog ib qho tseem ceeb hauv kev kho cov dej khib nyiab furfural. Txawm li cas los xij, nyob rau hauv qhov project commissioning theem, aerobic commissioning yuav nkim ntau lub sij hawm thiab nyiaj txiag, uas yuav ua rau kom tus nqi ntawm cov dej kho tej yaam num, xws li commissioning. Yog tias nws tsis zoo, nws yuav ua rau tag nrho cov txheej txheem tsis tuaj yeem khiav, yog li aerobic debugging tseem ceeb heev rau tag nrho qhov project, tab sis cov as-ham tseem ceeb hauv aerobic debugging.
Cov dej khib nyiab tsim los ntawm furfural yog nyob rau hauv Complex organic wastewater, uas muaj cetic acid, furfural thiab cawv, aldehydes, ketones, esters, organic acids thiab ntau yam organics, PH yog 2-3, siab concentration hauv COD, thiab phem nyob rau hauv biodegradability. .
Cov txheej txheem suav saturated chav ua cua sov qhov chaw, evaporation system ua.
Cov dej khib nyiab vaporized, txhawb siab kom ncav cuag qhov yuav tsum tau ua, rov ua dua cov furfural thiab cua sov los ntawm cov dej khib nyiab kom paub cov dej khib nyiab rov ua dua tshiab hauv cov txheej txheem tsim khoom. Lub cuab yeej txais kev pabcuam tsis siv neeg los tswj.

Cov txheej txheem tsim tawm hydrogen peroxide
Cov txheej txheem tsim cov hydrogen peroxide Cov tshuaj formula ntawm hydrogen peroxide yog H2O2, feem ntau hu ua hydrogen peroxide. Qhov tshwm sim yog cov kua tsis muaj xim tsis muaj pob tshab, nws yog ib qho muaj zog oxidant, nws cov tshuaj aqueous yog tsim rau kev kho mob qhov txhab tshuaj tua kab mob thiab tshuaj tua kab mob ib puag ncig thiab tshuaj tua kab mob. Nyob rau hauv ib txwm muaj xwm txheej, nws yuav decompose rau hauv dej thiab oxygen, tab sis lub decomposition nas ...

Furfural thiab pob kws cob ua cov txheej txheem furfural
Cov ntsiab lus ntawm Pentosan tsob nroj fiber ntau cov ntaub ntawv (xws li pob kws cob, txiv laum huab xeeb plhaub, paj rwb cov hulls, nplej hulls, sawdust, paj rwb ntoo) yuav hydrolysis rau hauv pentose nyob rau hauv lub fluence ntawm tej yam kub thiab catalyst, Pentoses tawm tawm peb dej molecules los tsim furfural. Lub pob kws cob yog siv los ntawm cov ntaub ntawv feem ntau, thiab tom qab ib tug series ntawm cov txheej txheem uas muaj xws li Purification, crushing, nrog acid hy...
