摘要
藻类对金属离子具有较强的富集能力，可作为生物吸附应用于工业污水中有毒、放射性金属的去除及稀有、贵重金属的回收，高效、经济、简便、选择性好，尤其适用于低浓度及一般方法不易去除的金属，是一种极有应用价值的传统方法的替代或辅助手段。藻类主要是通过生物吸附的途径去除及回收金属，多采用自由活细胞与固定化细胞两种富集体系。目前人类环境中金属污染仍相当严重，利用藻类富集这一生物工程技术处理含金属的工业污水，无论对于环境的改善还是有限资源的再利用，都具有巨大的经济价值及广阔的发展前景。
Algae are able to bioaccumulate a lot of metals in solutions.Being efficient,economic,simple and selective,they can remove or recovery metals from industrial waste water mainly through biosorption,especially for the metals in low concentration or that can not be removed by tranditional mothods.Two kinds of accumulation systems,living cell system and immobilised cell systems are used for bioaccumuation.There is a bright facture for the application of this biological engineering technology in either environmental improvement or resources reuse.
