Heavy hlau khib nyiab kho hauv RO dej kho qhov system
Tso lus
RO thev naus laus zis tau siv rau hauv kev kho cov dej khib nyiab hnyav ua ntej, thiab ntau qhov kev tshawb fawb tau ua tiav hauv tsev thiab txawv teb chaws. Raws li thaum ntxov xyoo 1970, RO thev naus laus zis tau siv rau hauv kev kho cov dej khib nyiab electroplating, feem ntau yog siv rau kev kho cov nickel plating, chromium, zinc rinsing dej thiab sib tov hnyav hlau khib nyiab.
MohsenNiaa ntxiv Na2EDTA rau chelate Cu2 ntxiv thiab Ni2 ntxiv ions, thiab tom qab ntawd lim los ntawm RO, ion rejection tus nqi ntawm Cu2 ntxiv thiab Ni2 ntxiv tuaj yeem nce mus rau 99.5 feem pua. Covarrubias, Bo-dalo, thiab lwm yam. siv RO daim nyias nyias los kho cov dej khib nyiab, thiab cov txiaj ntsig tau pom tias RO daim nyias nyias muaj kev tshem tawm siab ntawm chromium thiab cov organic teeb meem hauv tawv kev lag luam dej khib nyiab.
Changsha Liyuan New Materials Co., Ltd. siv cov txheej txheem sib cais membrane kom mloog zoo rau electroplating npib tsib xee yaug dej, thiab tus nqi tuav ntawm nickel ions yog ntau dua 99 feem pua. Tom qab ib-theem nanofiltration thiab ob-theem RO concentration, cov concentration ntawm npib tsib xee ions nyob rau hauv cov concentrated tov mus txog 50g·L- 1. Cov permeate tuaj yeem rov siv tau tom qab kev kho mob. Zhang Liankai tau kho cov pH ntawm cov dej khib nyiab hnyav uas tau tsim nyob rau hauv lub rhiav pickling ntawm cov ntawv luam tawm Circuit Board rau nruab nrab, thiab tom qab ntawd siv cov txheej txheem ultrafiltration ntxiv rau RO los ua qhov kev sim. Qhov kev tshem tawm ntawm Cu2 ntxiv thiab tag nrho cov khoom yaj tag los ntawm RO system yog 99.9 feem pua thiab 98.9 feem pua.
