Kev kho dej khib nyiab ntau lawm txheej txheem

Raws li cov yam ntxwv ntawm cov dej khib nyiab zoo thiab cov yam ntxwv tawm, cov txheej txheem kho tuaj yeem muab faib ua tsib ntu: pretreatment, kev kho lub cev thiab tshuaj, kev kho biochemical, kev kho mob siab heev thiab kev kho sludge. Ntawm lawv, kev kho mob siab heev yog cov txheej txheem uas siv cov twj centrifugal tshaj plaws.

1. Cov txheej txheem kho ua ntej

Cov dej khib nyiab tau nqa mus rau qhov kev tshuaj ntsuam inclined los ntawm 1 # dej tank. Cov txheej txheem static inclined screen yog qhov tseem ceeb rau kev ua haujlwm ntawm tag nrho cov nroj tsuag dej ua ntej lub cev. Lub twj tso kua mis yog unobstructed. Cov ntxaij vab tshaus inclined yog siv los rov qab cov ntaub ntawv fiber ntau. Hauv kev kho cov dej khib nyiab papermaking, nws yog qhov chaw tseem ceeb kom tshem tawm cov khib nyiab pov tseg thiab txo cov kev ua haujlwm ntawm cov chaw kho mob tom ntej. Cov fiber ntau intercepted tuaj yeem rov ua dua rau kev tsim khoom tom qab tau sau.

2. Cov txheej txheem kho lub cev thiab tshuaj lom neeg

Kev kho cov dej khib nyiab yog ib txoj haujlwm tsim nyog, thiab kev tsim cov khoom siv hluav taws xob zoo thiab cov txheej txheem tsim nyog ua ke qhia txog kev txhim kho thev naus laus zis thiab kev lag luam ntawm qhov project. Muaj ntau ntau txoj kev siv lub cev thiab tshuaj pretreatment, tab sis feem ntau siv txoj kev yog nag lossis daus thiab huab cua flotation. Cov yam ntxwv tseem ceeb ntawm kev sib cais huab cua yog kev sib cais ceev ceev, tsis tshua muaj sludge noo noo cov ntsiab lus, me hneev taw, ruaj khov nyhuv, thiab daim ntawv thov dav hauv papermaking wastewater kho. Raws li kev pom ntawm cov yam ntxwv ntawm cov dej phwj tuaj nrog cov dej ntim loj, cov khib nyiab siab siab, thiab siab insoluble COD thiab BOD cov ntsiab lus, cov txheej txheem dej ntiav ntiav yog siv los ua cov txheej txheem kev kho lub cev thiab tshuaj lom neeg rau cov dej khib nyiab.

3. Cov txheej txheem kho biochemical: kev kho aerobic thiab kev kho anaerobic

Kev kho biochemical ntawm cov dej khib nyiab yog ib txoj kev kho mob lom uas siv cov kab mob ua kom cov kab mob adsorb thiab degrade cov pa phem hauv cov dej khib nyiab raws li ib puag ncig tsim nyog. Raws li qhov sib txawv ntawm cov pa oxygen ntawm cov kab mob siv, kev kho biochemical tuaj yeem muab faib ua ob pawg: kev kho aerobic thiab kev kho anaerobic.

4. Advanced processing technology (tseem ceeb rau lub ntsiab lus thib plaub)

Tom qab kev kho mob biochemical thib ob, cov khoom seem uas raug tshem tawm hauv cov dej ntws tawm yog cov khoom siv roj ntsha thiab cov khoom tsis sib xws nrog cov khoom me me xws li 1mm txog 10μm. Yuav luag tag nrho cov khoom no yog cov organic. 50% -80% ntawm BOD tus nqi ntawm cov tshuaj tua kab mob thib ob yog los ntawm cov khoom no. Txhawm rau txhim kho kev ruaj ntseg ntawm cov dej kho thib ob, nws yog qhov yuav tsum tau tshem tawm cov khoom no.

5. Cov txheej txheem kho sludge

Lub hom phiaj ntawm kev kho sludge yog kom decompose cov organic teeb meem, tua cov kab mob pathogenic thiab cov qe kab mob parasite, stabilize cov sludge, thiab siv cov peev txheej hauv cov sludge kom ntau li ntau tau. Raws li qhov xwm txheej tiag tiag ntawm txoj haujlwm kho dej khib nyiab, cov txheej txheem thickening + lub cev qhuav dej feem ntau yog xaiv los kho cov sludge, thiab cov sludge ruaj khov thiab lub cev qhuav dej yog thauj thiab pov tseg.
