摘要:
在膜生物反应器（MBR）工艺实际运行过程中，污水中含有的硬质颗粒物等会对膜表面或膜内部造成物理性损伤，并且伴随聚偏氟乙烯（PVDF）膜使用时间的增长，周期性的化学清洗也会导致膜材料老化加重，直至出现产水性能不断下降、维护成本逐渐上升的现象，膜组件不可避免地达到寿命终点。基于实验室小试，采用二甲基亚砜（DMSO）转换膜结构，并且使用单宁酸-铁涂覆的方式修复工程受损膜，使其恢复生产能力，并进行工程应用中试。经过135 d的连续运行发现，修复再生膜的产水性能持续显著优于对照组，出水水质稳定，经修复后膜组件的物理化学性能均得到较为全面的提升。
Abstract:
In the actual operation of membrane bioreactor (MBR), the hard particles contained in sewage will cause physical damage to the membrane surface or inside the membrane. With the increase of the service time of polyvinylidene fluoride (PVDF) membrane, periodic chemical cleaning will also lead to the aging of the membrane materials, and the membrane module will inevitably reach the end of its life when the phenomenon such as continuous decline of water production performance and gradual increase of maintenance cost is observed. Based on the laboratory experiment, the membrane structure was transformed by dimethyl sulfoxide (DMSO), the damaged membrane was repaired by tannic acid-iron coating to restore its production capacity, and the method was eventually applied in a pilot experiment. After 135 days of continuous operation, the water production performance of the repaired and regenerated membrane was significantly better than that of the control group, the effluent quality was stable, and the physical and chemical properties of the repaired membrane modules were improved comprehensively.
