    Abstract: A magnetic carrier and a membrane bioreactor system for water treatment using the same are provided to improve the filtration performance of membranes, recycle the enzyme and stably operate the water treatment process for a long time compared to the conventional membrane bioreactor process. A magnetic carrier comprises a magnetic core, an enzyme immobilizing layer formed on the magnetic core, and an enzyme for inhibiting the biofilm formation which is immobilized onto the enzyme immobilizing layer. The magnetic core is powders, particles, beads, or resins comprising magnetic substances. The enzyme immobilizing layer is laid up on the magnetic core by an electrostatic interaction. The enzyme immobilizing layer is formed of chitosan, poly(2-hydroxyethyl methacrylate) or cellulose. The enzyme for inhibiting the biofilm formation is a quorum sensing inhibition enzyme.

    Abstract translation: 提供一种用于水处理的磁性载体和膜生物反应器系统,以提高膜的过滤性能,循环使用酶,并与常规膜生物反应器方法相比长时间稳定地操作水处理过程。 磁性载体包括磁芯,形成在磁芯上的酶固定层和用于抑制固定在酶固定层上的生物膜形成的酶。 磁芯是包含磁性物质的粉末,颗粒,珠粒或树脂。 酶固定层通过静电相互作用放置在磁芯上。 酶固定层由壳聚糖,聚(甲基丙烯酸2-羟乙酯)或纤维素形成。 用于抑制生物膜形成的酶是法定感测抑制酶。
