摘要
介绍了近年来国内外壳聚糖及其衍生物在不同工业污水处理中的应用及相关机理。壳聚糖及其衍生物作为絮凝剂、金属离子的螯合剂以及有机物的吸附剂,在工业污水处理中有着相当广泛的应用,主要是絮凝和处理含重金属离子的工业废水,环境效益显著。壳聚糖及其衍生物是绿色的水处理剂,其未来发展的方向是合成性能更为优良的改性壳聚糖,与其他技术复合使用,并深入研究其对复杂工业废水的处理能力。
The development and applications of chitosan and its derivatives in the treatment of different sources of industrial wastewater have been reviewed in recent years. Chitosan and its derivatives can be used as flocculant, heavy metal-chelating agent and adsorbent for organics, which offer widespread applications in industrial effluent treatment. They are applied mosdy to the flocculation and treatment of industrial wastewater containing heavy metal and are of tremendous environmental benefits. Chitosan and its derivatives are green reagents and degradable in nature. Its future developing trend will be to synthesize better ramifications,to combine with other techniques and to investigate their treating effects for complex industrial wastewater.
