摘要
随着工业的高速发展,水体重金属污染越来越严重,对生态环境和人类身体健康都造成了很大威胁。对膜的基本特征和分离过程进行了介绍,重点阐述了重金属废水的膜处理技术,包括电渗析、反渗透、微滤、超滤、纳滤和液膜技术,并展望了膜技术的应用前景。
With rapid development of industry, heavy metal pollution poses great threat to ecological environment and human health as well . The paper first presented basic characteristics and separation process for membrane, then it detailed various membrane treatment techniques, including electrodialysis, reverse osmosis, micro filter, ultrafiltration, nanofiltration and liquid membrane technology. The author finally concludes future application prospect for membrane technology.
