Hnyav hlau tshem tawm yog cov ntsiab lus dav dav rau cov neeg ua haujlwm uas tshwj xeeb tshem tawm cov hlau hnyav thiab arsenic hauv cov dej khib nyiab hauv cov dej phwj tuaj. Hnyav hlau tshem tawm yog cov tshuaj lom neeg.
Los ntawm kev ntxiv cov tshuaj tua kab mob hnyav, cov hlau hnyav thiab arsenic hauv cov dej khib nyiab tuaj yeem ua cov tshuaj lom neeg los tsim cov dej-insoluble, uas tuaj yeem sib cais los ntawm cov dej thiab ua kom cov dej khib nyiab ntshiab. Tus nqi ntawm cov sludge yog me me, thiab cov concentration ntawm cov hlau hnyav yog siab, uas tuaj yeem rov ua dua thiab smelted. Fields: mining, hlau smelting thiab ua, tshuaj ntau lawm, electroplating, electronics, luam ntawv thiab dyeing thiab lwm yam lag luam.
Tam sim no muaj ob hom tshuaj rau kev kho cov dej khib nyiab hnyav uas twb muaj lawm hauv khw, ib qho yog cov khoom siv hnyav hlau, thiab lwm yam yog cov khoom hnyav hlau tshem tawm; cov hlau hnyav tshem tawm thiab cov hlau hnyav hnyav yog qhov tseem ceeb tib yam ntawm cov khoom, ob qho tib si Xanthate thiab dithiocarbamate derivatives nrog tsawg toxicity.
Tus phooj ywg environmentallyhnyav hlau tshem tawm CW-15tsim los ntawm peb lub tuam txhab yog ib qho ntsuab thiab tsis muaj tshuaj lom cov organic polymer, uas tuaj yeem muaj kev tshem tawm zoo ntawm cov hlau hnyav. Feem ntau, nws yog kho nrog hnyav hlau tshem tawm thiab hnyav hlau ntxiab. Lub slag yog qhov nyuaj rau kev rov ua dua thiab txheej txheem, thiab muaj kev pheej hmoo ntawm cov pa phem thib ob; thiab peb lub tuam txhab CW-15 yog ntsuab hnyav hlau precipitant, thiab tsis muaj kev pheej hmoo ntawm cov pa phem thib ob tom qab kev kho hlau hnyav.
Heavy Hlau Ion Catcher Tus Neeg Saib Xyuas tuaj yeem tshem tawm cov hlau hnyav los ntawm cov dej khib nyiab xws li: desulfurization cov dej khib nyiab los ntawm Coal-fired fais fab nroj tsuag (ntub desulfurization txheej txheem) cov dej khib nyiab los ntawm Printed circuit board plating plant (Plated copper), Electroplating factory (Zinc), Photographic rinse, Petrochemical Cog, Automobile ntau lawm cog thiab lwm yam.Hnyav Hlau Tshem Tawm Tus Neeg Saib Xyuas CW-15yog ib qho tsis muaj tshuaj lom thiab ib puag ncig-phooj ywg hnyav hlau catcher. Cov tshuaj no tuaj yeem tsim ib qho chaw ruaj khov nrog feem ntau cov monovalent thiab divalent hlau ions hauv cov dej khib nyiab, xws li: Fe2+, Ni2+, Pb2+, Cu2+, Ag+, Zn2+, Cd2+, Hg2+, Ti+ thiab Cr3+, tom qab ntawd mus txog lub hom phiaj ntawm kev tshem tawm lub hlwb hnyav. los ntawm dej. Tom qab kev kho mob, nag lossis daus tsis tuaj yeem yaj los ntawm nag, Tsis muaj teeb meem ua paug thib ob.
Cov hauv qab no yog nws qhov zoo:
1. Kev nyab xeeb siab. Tsis muaj tshuaj lom, tsis muaj ntxhiab tsw phem, tsis muaj tshuaj lom cov khoom siv tom qab kho.
2. Cov nyhuv tshem tawm zoo. Nws tuaj yeem siv dav hauv pH ntau, tuaj yeem siv rau hauv cov kua qaub lossis alkaline cov dej khib nyiab. Thaum cov hlau ions coexist, lawv tuaj yeem raug tshem tawm tib lub sijhawm. Thaum cov hlau hnyav ions nyob rau hauv daim ntawv ntawm cov ntsev complex (EDTA, tetramine thiab lwm yam) uas tsis tuaj yeem raug tshem tawm tag nrho los ntawm txoj kev hydroxide precipitate, cov khoom no tuaj yeem tshem tawm thiab. Thaum nws sediment cov hlau hnyav, nws yuav tsis yooj yim cuam tshuam los ntawm coexisted ntsev hauv dej khib nyiab.
3. Zoo flocculation nyhuv. Khoom-kua sib cais yooj yim.
4.Heavy hlau sediments yog ruaj khov, txawm nyob rau ntawm 200-250 ℃ los yog dilute acid.
5. Cov txheej txheem ua haujlwm yooj yim, yooj yim sludge dewatering.
"Sincerity, Innovation, Rigorousness, and Efficiency" yog qhov kev xav tsis tu ncua ntawm peb lub tuam txhab rau lub sij hawm ntev kom tau nrog ib leeg nrog cov neeg yuav khoom rau kev sib nrig sib pab thiab kev sib nrig sib nqi zog rau cov khoom zoo.Suav Chaw Tsim Khoom, Peb zoo siab tos txais cov neeg siv khoom hauv tsev thiab txawv teb chaws xa cov lus nug rau peb, peb tau txais 24 teev ua haujlwm ua haujlwm! Txhua lub sijhawm nyob qhov twg peb tseem nyob ntawm no yog koj tus khub.
