Cov tshuaj tshem cov hlau hnyav yog lo lus dav dav rau cov tshuaj uas tshem tawm cov hlau hnyav thiab arsenic hauv cov dej khib nyiab hauv kev kho dej phwj tuaj. Cov tshuaj tshem cov hlau hnyav yog ib yam tshuaj lom neeg.
Los ntawm kev ntxiv cov tshuaj tshem tawm cov hlau hnyav, cov hlau hnyav thiab arsenic hauv cov dej khib nyiab ua rau cov tshuaj lom neeg tsim cov tshuaj uas tsis yaj hauv dej, uas tuaj yeem sib cais los ntawm dej thiab ua rau cov dej khib nyiab ntshiab. Cov sludge me me, thiab qhov concentration ntawm cov hlau hnyav siab, uas tuaj yeem rov ua dua thiab smelted. Cov teb: mining, hlau smelting thiab ua cov hlau, tshuaj lom neeg tsim, electroplating, electronics, luam ntawv thiab dyeing thiab lwm yam lag luam.
Tam sim no muaj ob hom tshuaj siv los kho cov dej khib nyiab hlau hnyav uas twb muaj nyob hauv khw lawm, ib qho yog tshuaj tshem cov hlau hnyav, thiab lwm qhov yog tshuaj tshem cov hlau hnyav; cov tshuaj tshem cov hlau hnyav thiab cov tshuaj tshem cov hlau hnyav yog tib hom tshuaj, ob qho tib si Xanthate thiab dithiocarbamate derivatives uas muaj tshuaj lom tsawg.
Tus phooj ywg ib puag ncigCov hlau hnyav tshem tawm CW-15Peb lub tuam txhab tsim tawm yog cov polymer organic ntsuab thiab tsis muaj tshuaj lom, uas kuj tseem tuaj yeem muaj cov txiaj ntsig zoo rau kev tshem tawm cov hlau hnyav. Feem ntau, nws raug kho nrog cov tshuaj tshem tawm hlau hnyav thiab cov cuab yeej ntes hlau hnyav. Cov slag nyuaj rau rov ua dua tshiab thiab ua tiav, thiab muaj kev pheej hmoo ntawm kev ua qias tuaj thib ob; thiab peb lub tuam txhab CW-15 yog cov hlau hnyav ntsuab precipitant, thiab tsis muaj kev pheej hmoo ntawm kev ua qias tuaj thib ob tom qab kev kho hlau hnyav.
Tus Neeg Sawv Cev Hnyav Hlau Ion Catcher tuaj yeem tshem tawm cov hlau hnyav ntawm cov dej khib nyiab xws li: desulfurization wastewater los ntawm Thee-fired fais fab nroj tsuag (ntub desulfurization txheej txheem) wastewater los ntawm Printed circuit board plating cog (Plated tooj liab), Electroplating Hoobkas (Zinc), Photographic rinse, Petrochemical Cog, Tsheb ntau lawm cog thiab lwm yam.Tus Neeg Sawv Cev Tshem Tawm Hlau Hnyav CW-15yog ib qho tshuaj 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 +, tom qab ntawd ua tiav lub hom phiaj ntawm kev tshem tawm cov tshuaj lom hauv dej. Tom qab kho, cov nag tsis tuaj yeem yaj los ntawm nag, Tsis muaj teeb meem kev ua qias tuaj.
Cov hauv qab no yog nws cov txiaj ntsig:
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.
