Tus Neeg Sawv Cev Tshem Tawm Hlau Hnyav CW-15
Kev piav qhia
Tus Neeg Sawv Cev Tshem Tawm Hlau HnyavCW-15yog ib yam khoom uas tsis muaj tshuaj lom thiab tsis ua rau ib puag ncig puas tsuaj. Cov tshuaj no tuaj yeem tsim cov tshuaj ruaj khov nrog feem ntau cov hlau ions monovalent thiab divalent hauv cov dej khib nyiab, xws li: Fe2+,Ni2+,Pb2+,Cu2+,Ag+,Zn2+,Cd2+,Hg2+,Ti+thiab Cr3+, ces mus txog lub hom phiaj ntawm kev tshem tawmkev uahnyav hlwb los ntawm dej. Tom qab kev kho mob, cov Precipitationtsis tuaj yeem yajdlos ntawm nag, Muajtsis yog'tsis muaj dab tsiteeb meem kev ua qias tuaj theem ob.
Cov Kev Ntsuam Xyuas Los Ntawm Cov Neeg Siv Khoom
Daim Ntawv Thov
Tshem tawm cov hlau hnyav ntawm cov dej khib nyiab xws li: cov dej khib nyiab desulfurization los ntawm lub chaw tsim hluav taws xob thee (txheej txheem desulfurization ntub) cov dej khib nyiab los ntawm lub Hoobkas plating Printed circuit board (Plated copper), Hoobkas Electroplating (Zinc), Kev yaug duab, Hoobkas Petrochemical, Hoobkas tsim tsheb thiab lwm yam.
Qhov zoo
1. Muaj kev nyab xeeb heev. Tsis muaj tshuaj lom, tsis muaj ntxhiab tsw phem, tsis muaj tshuaj lom tom qab kho.
2. Kev tshem tawm zoo. Nws tuaj yeem siv rau hauv ntau yam pH, tuaj yeem siv rau hauv cov dej khib nyiab uas muaj kua qaub lossis alkaline. Thaum cov hlau ions nyob ua ke, lawv tuaj yeem raug tshem tawm tib lub sijhawm. Thaum cov hlau ions hnyav nyob rau hauv daim ntawv ntawm cov ntsev sib xyaw (EDTA, tetramine thiab lwm yam) uas tsis tuaj yeem tshem tawm tag nrho los ntawm hydroxide precipitate txoj kev, cov khoom no tuaj yeem tshem tawm nws thiab. Thaum nws tso cov hlau hnyav, nws yuav tsis yooj yim thaiv los ntawm cov ntsev sib koom ua ke hauv cov dej khib nyiab.
3. Cov nyhuv flocculation zoo. Kev sib cais cov khoom khov thiab kua yooj yim.
4. Cov hlau hnyav ruaj khov, txawm tias ntawm 200-250 ℃ lossis dilute acid.
5. Txoj kev ua yooj yim, yooj yim sludge dewatering.
Cov Lus Qhia Tshwj Xeeb
Txoj Kev Thov
Cov dej khib nyiab → Kho PH rau 7-10 → Ntxiv CW 15 nrog kev nplawm rau 30 feeb → Ntxiv cov organic flocculant nrog kev nplawm → do qeeb qeeb rau 15 feeb → Sedimentation → Lim → Dej kho
Cov koob tshuaj siv ntawm CW 15 rau 10PPM hlau hnyav ion
Pob thiab Storge
Pob khoom
Cov kua tau ntim rau hauv lub thawv polypropylene, 25kg lossis 1000kg nruas
cov khoom khov tau ntim rau hauv hnab yas sib xyaw, 25Kg / hnab.
Kev ntim khoom tshwj xeeb muaj.
Storge
Khaws cia rau hauv tsev, khaws kom qhuav, muaj cua nkag, tiv thaiv kom tsis txhob raug tshav ntuj ncaj qha, tsis txhob raug kua qaub thiab oxidizer.
Lub sijhawm khaws cia yog ob xyoos, tom qab ob xyoos, nws tsuas yog siv tau tom qab rov kuaj xyuas thiab tsim nyog.
Cov tshuaj lom neeg tsis txaus ntshai.
Kev Thauj Mus Los
Thaum thauj mus los, nws yuav tsum tau kho raws li cov tshuaj lom neeg, zam kev tawg pob khoom thiab tiv thaiv kom tsis txhob raug tshav ntuj thiab nag.
