利用固定化细胞技术处理废水研究进展

固定化细胞技术是一门新兴的废水处理技术。与固定化酶技术相比,固定化细胞技术保持了原有的多酶系统,对于需要多酶顺序作用的反应更具优势,且不需要辅酶再生。其缺点是必须使用胞内酶,且难以去除细胞内的“副作用”酶。介绍了目前常见的四类固定化方法(即吸附法、包埋法、共价结合法和交联法)、三类固定化细胞载体材料(即有机高分子载体、无机载体和复合载体)以及该方法在废水处理中的应用,并提出了在应用中有待解决的问题。

Development of Immobilized Cell Technology for Wastewater Treatment

Immobilized cell technology is a new technology for wastewater treatment. In this paper, four immobilization methods including absorption, bury, combined and cross-linking methods and three type carriers including organic high-molecular, inorganic high-molecular and complex carriers are introduced. The operating methods of this technology applied to water treatment are presented. Some problems which must be solved are put forward.
