酶固定膜反应器兼具有反应和分离两种功能，是酶工程领域中较活跃的研究课题［１～３］．随着酶固定化技术和水平的提高，各种固定化酶生物反应器不断涌现，其中以采用固定化脲酶技术制作的人工肾最为成功［３］．在国内，采用分子筛和聚乙烯醇高含水胶作载体固定化脲酶已... Enzyme immobilized membrane reactor with both reaction and separation functions, is more active in the field of enzyme engineering research [1 ~ 3]. As enzyme immobilization technology and the level of improvement, a variety of immobilized enzyme bioreactors continue to emerge, of which the use of immobilized urease technology is the most successful artificial kidney [3]. In China, using molecular sieve and polyvinyl alcohol high water-containing plastic immobilized urease carrier has been ...
