Kev piav qhia
CW-15 yog ib qho tshuaj uas tsis muaj tshuaj lom thiab tsis ua rau ib puag ncig puas tsuaj. 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+, ces mus txog lub hom phiaj ntawm kev tshem tawm cov dej hnyav. Tom qab kev kho mob, cov nag tsis tuaj yeem yaj los ntawm nag, Tsis muaj teeb meem kev ua qias tuaj ntxiv.
Daim Ntawv Thov
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.
