摘要
生物膜载体是生物膜工艺的核心部分,载体的选择适当与否直接影响到废水的处理效果。概述了废水处理用生物膜载体的现状与发展,重点介绍了有机合成高分子生物膜载体在亲水性、生物亲和性和磁性等方面的改性研究,壳聚糖、藻酸盐和纤维素等可降解材料作为生物膜载体在废水处理中的应用研究。针对当今生物膜载体应用带来的二次污染问题,提出了解决办法和发展方向,指出可降解生物膜载体的应用可有效避免废弃生物膜载体处理带来的二次污染,是生物膜载体研究的一个重要发展方向。
As an important part of the biofilm process,the selection of biofilm carriers will directly influence the effect of wastewater treatment. The status and development of the biofilm carriers for wastewater treatment were reviewed in this paper,and the modification research of the organic synthetically polymeric biofilm carriers in the aspects of hydrophilicity,biocompatibility,magnetism,etc,was mainly introduced. The research progress of natural degradable biofilm carriers,such as chitosam,alginate,cellulose,etc,was also studied in the paper. Suggestions were provided to solve the problem of the secondary pollution of carrier. Since using degradable material could help avoid secondary pollution brought by carriers,it would be an important trend on biofilm carrier.
