摘　　要：近年来,利用固定化藻类去除废水中的重金属因其有效、低廉、特别是能处理低浓度废水引起了广泛重视。我们根据藻类吸附重金属的机理、藻类固定化技术以及固定化藻类处理重金属废水的研究结果,认为如何解决藻细胞的渗漏问题、选择最好的固定载体与固定方法、开发合理的生物反应器、采用温和的洗脱液等都是其用于大规模废水处理的重点和难点,解决上述技术难题是固定化藻类技术处理重金属废水规模化发展的关键。The use of immobilized algae for wastewater heavy metals removal purposes have gained attention during recent years due to its high efficiency and cost- effectiveness, particularly at low metal concentrations. According to the mechanism for heavy metals ab- sorption of algae, the techniques of immobilization, and the research result of immobilized algae for wastewater heavy metals removal. We think that the key point and difficult point of dealing with large-scale wastewater is how to solve the leaking problem of algae cell, choosing the best immobilized carriers and methods ,developing rational biosreactor and using gentle washing liquid. Solving the upper technical difficulties is the key point of mass-development of using immobilized algae technic to deal with wastewater heavy metals removal.
