摘要
为了评定主流活性炭材料和膜材料对常见污染物的去除能力,研究过程从市场中分别采购了 6 种不同的活性炭和膜过滤单元,包括活性炭纤维、煤质颗粒活性炭、椰壳类活性炭、超滤膜和纳滤膜.利用Pb2+、Fe3+、Cu2+、Zn2+制备金属离子污染水,再制备一定量的有机碳污染水.分别使用活性炭和膜过滤单元进行去污,检测截留率或者去除率,从而确定性能最佳的去污材料.
Abstract
In order to evaluate the removal ability of mainstream activated carbon materials and membrane materials for common pollutants,the research process purchased six different types of activated carbon and membrane filtration units from the market,including activated carbon fibers,coal particle activated carbon,coconut shell activated carbon,ultrafiltration membranes,and nanofiltration membranes.Prepare metal ion polluted water using Pb2+,Fe3+,Cu2+,Zn2+,and then prepare a certain amount of organic carbon polluted water.Use activated carbon and membrane filtration units separately for decontamination,detect retention or removal rates,and determine the best performing decontamination material.
