摘要(Abstract)：

针对工业园区废水回用技术尚不普及的问题，利用超滤系统处理某工业园区废水，探究超滤系统的运行效能，以平均膜通量、膜通量衰减率为响应值，利用正交实验优化超滤系统的运行工况，采用三维荧光光谱分析超滤系统去除的主要有机污染物类型，并通过Hermia模型拟合滤饼层模型、中间阻塞模型、标准阻塞模型、完全阻塞模型分析膜污染机制。结果表明：超滤系统运行的最优运行工况是初始膜通量为68 L/(m²·h),曝气强度为1.0 L/min,运行间歇时间比为30 min∶4 min;在最优运行工况条件下，工业园区废水浊度、化学需氧量的平均减小率分别为92.3%、 17.8%,总氮、总磷的平均去除率分别为10.3%、 15.9%;超滤系统去除的主要有机污染物为工业园区废水中的类色氨酸蛋白质和微生物代谢产生的类色氨酸蛋白质；膜污染阻力主要为物理可逆污染阻力，膜污染机制主要符合中间阻塞模型的特点，回归系数为0.996 3,并且滤饼层模型、标准阻塞模型、完全阻塞模型的回归系数也均大于0.9,表明超滤系统处理工业园区废水导致的膜污染并非单一膜污染机制作用的结果，而是多种膜污染机制协同作用的结果。
