Cov Sludge Nplaum Yog Dab Tsi?
Cov sludge nplaum yog hais txog cov sludge uas tsis zoo rau kev tshem dej tawm, muaj viscosity siab, thiab muaj zog lo rau. Feem ntau nws qhia tau tias:
- Muaj peev xwm khaws dej tau zoo
- Cov qauv zoo li gel los yog slimy
- Kev lim dej tsis zoo
- Qis qhuav ncuav mog qab zib tom qab dewatering
- Cov khoom siv txhaws thiab ua qias tuaj
Cov Chaw Feem Ntau ntawm Cov Sludge Nplaum
Cov av nplaum nplaum feem ntau tshwm sim hauv cov lag luam xws li:
Cov laj thawj tseem ceeb
Cov protein, cov rog, thiab cov carbohydrates ua rau cov sludge viscosity nce ntxiv.
Cov tshuaj polymeric extracellular (EPS) ntau dhau uas cov kab mob tsim tawm tsim cov matrix nplaum.
Cov flocculants tsis txaus lossis tsis sib xws ua rau cov flocs tsis muaj zog lossis nplaum dhau.
Cov sludge me me uas muaj qhov them tsis raug ntawm qhov chaw tiv thaiv kev sib sau ua ke zoo.
Vim Li Cas Cov Sludge Nplaum Yog Ib Qho Teeb Meem
Cov av nplaum nplaum tuaj yeem cuam tshuam loj heev rau kev ua haujlwm ntawm cov dej khib nyiab:
- Txo Kev Ua Haujlwm ntawm Kev Tshem Dej Cov av nplaum khaws dej ntau dua, ua rau: Cov khoom ua ncuav mog qab zib tsawg dua, cov av nplaum ntau dua, cov nqi pov tseg ntau dua.
- Cov Teeb Meem Khoom Siv Cov xovxwm lim siv txoj siv yooj yim txhaws, cov centrifuges poob qis kev ua haujlwm, cov ntaub lim yuav tsum tau ntxuav ntau zaus.
- Kev Siv Tshuaj Ntau Ntxiv Kev ua flocculation tsis zoo ua rau muaj cov tshuaj ntau dua.
- Kev Tsis Txawj Ua Haujlwm Cov yam ntxwv ntawm cov sludge tsis sib xws ua rau kev tswj cov txheej txheem nyuaj.
Yuav ua li cas PAM daws cov teeb meem nplaum nplaum
- Kev Them Nqi Tsis Txaus Cov av nplaum nplaum feem ntau muaj cov colloids uas muaj cov nqi tsis zoo. Cationic PAM ua rau cov nqi no tsis muaj zog, ua rau cov khoom me me los ua ke.
- Txoj Kev Sib Txuas Lus PAM cov molecule tsim cov saw ntev uas txuas ntau lub pieces, tsim cov flocs loj dua thiab muaj zog dua.
- Cov Qauv Floc Zoo Dua PAM uas raug xaiv kom zoo yuav ua rau muaj: Cov flocs ntom ntom, me me, txo cov sludge viscosity, thiab tso dej tawm zoo dua.
- Kev Tshem Dej Zoo Dua Nrog kev siv PAM kom zoo tshaj plaws: Cov khoom khov ua ncuav mog qab zib nce ntxiv ntau heev, qhov ceev ntawm kev lim dej zoo dua, thiab qhov ntim sludge txo qis.
Cov Kauj Ruam Ib Kauj Ruam rau Kev daws cov Sludge nplaum nrog PAM
Kauj Ruam 1
Kauj Ruam 2
Kho qhov hnyav molecular raws li qhov xav tau ntawm floc.
Txoj Cai Dav Dav: Cov khoom muaj organic ntau dua → Cov nqi ntau dua.
Kev kuaj hauv chav kuaj (kev kuaj hauv lub thawv) yog qhov tseem ceeb rau kev xaiv kom raug.
Kauj Ruam 3
Kev noj tshuaj ntau dhau los yog kev noj tshuaj tsawg dhau yuav ua rau cov sludge lo rau ntau dua.
Kev noj tshuaj tsis txaus → cov flocs tsis muaj zog
Kev noj tshuaj ntau dhau → rov ua kom ruaj khov thiab cov av nplaum nplaum
Kauj Ruam 4
Kev npaj tsis zoo yuav ua rau kev ua tau zoo tsis zoo. Cov ntsiab lus tseem ceeb:
- Yaj PAM maj mam rau hauv dej huv
- Siv 0.1–0.3% concentration
- Tsis txhob sib xyaw ua ke nrog high shear
- Cia lub sijhawm laus txaus (30–60 feeb)
