Cov Dej Zoo Tshaj Plaws hauv Suav Teb Tshem Tawm Chlorine Fluoride Cov Hlau Hnyav Cov Khoom Siv Uas Tsis Zoo

Tus neeg sawv cev tshem tawm cov hlau hnyav CW-15 yog cov khoom tsis muaj tshuaj lom thiab tsis zoo rau ib puag ncig. Cov tshuaj no tuaj yeem tsim cov khoom sib xyaw 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 hlau hnyav ntawm dej. Tom qab kho, nag tsis tuaj yeem yaj los ntawm nag, Tsis muaj teeb meem kev ua qias tuaj ntxiv.

Tshem tawm cov hlau hnyav ntawm cov dej khib nyiab xws li: cov dej khib nyiab desulfurization los ntawm lub zog fais fab thee (cov txheej txheem desulfurization ntub) cov dej khib nyiab los ntawm lub tshuab hluav taws xob Printed circuit board plating cog (Plated tooj liab), Electroplating Hoobkas (Zinc), Photographic rinse, Petrochemical Cog, Tsheb ntau lawm cog thiab lwm yam.
Nws muaj kev nyab xeeb siab, Tsis muaj tshuaj lom, tsis muaj ntxhiab tsw phem, tsis muaj tshuaj lom tom qab kho. Nws siv tau rau hauv ntau yam pH, siv tau rau hauv cov dej khib nyiab uas muaj kua qaub lossis alkaline. Thaum cov hlau ions sib koom 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 txoj kev hydroxide precipitate, 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. Kev sib cais khoom khov-kua yooj yim. Cov hlau hnyav ruaj khov, txawm tias ntawm 200-250 ℃ lossis dilute acid. Thaum kawg, nws muaj txoj hauv kev ua yooj yim, yooj yim sludge dewatering.
Peb muaj cov khoom siv niaj hnub. Peb cov khoom raug xa tawm mus rau Tebchaws Meskas, UK thiab lwm yam, txaus siab rau lub koob npe zoo ntawm cov neeg siv khoom rau Cov Dej Zoo Tshaj Plaws hauv Suav Teb Tshem Tawm Chlorine Fluoride Heavy Metals Sediments Impurities, Tam sim no peb muaj plaub qhov kev daws teeb meem tseem ceeb. Peb cov khoom muag zoo tshaj plaws tsis yog hauv Suav teb xwb, tab sis kuj tau txais tos los ntawm kev lag luam thoob ntiaj teb.
Tus nqi zoo tshaj plaws rau kev tshem tawm cov hlau hnyav, Peb lub tuam txhab yeej ib txwm hais txog lub hauv paus ntsiab lus ua lag luam ntawm "Zoo, Ncaj Ncees, thiab Cov Neeg Siv Khoom Ua Ntej" uas tam sim no peb tau txais kev ntseeg siab ntawm cov neeg siv khoom los ntawm tsev thiab txawv teb chaws. Yog tias koj txaus siab rau peb cov khoom lag luam, nco ntsoov tiv tauj peb kom paub ntxiv.
