摘要
生物吸附法是目前处理重金属废水的一种行之有效的方法,特别是对于低浓度废水,其优势明显,还可达到以废治废的目的。对废水重金属的生物吸附进行了综述,详细介绍了目前最具代表性的四种生物吸附机理以及已经开发出来的五种吸附工艺,同时还探讨了影响生物吸附重金属的多种因素和生物吸附剂的类型,展望了生物吸附废水中重金属在工业生产中的应用前景。
Nowadays, hiosorption is an effective method for the treatment of heavy metals bearing wastewater, especially for the wastewater of low metal concentration. In addition, the technology is also characterized by waste treatment with waste material. This paper reviewed the biosorption of heavy, metals in wastewater. The mechanism of biosorption which was most representative and the technology of biosorbents were introduced detailediy. In addition, the factors influencing the adsorption of heavy metals and the type of biosorbents were discussed. The application prospects of biosorption of heavy metals in wastewater were also studied.
