In this work, an innovative design of integrated photobioelectrochemcial system (IPB) and an algal harvesting method based on polyester-mesh membrane (MM) were investigated. The algal growth/harvesting period of 6 days led to the highest surface biomass productivity (SBP) of 0.88 g m⁻² day⁻¹ and the highest energy generation of 0.157 ± 0.001 kJ day⁻¹. The harvesting frequency of 3 times in an operational cycle (with three pieces of MM) enhanced the SBP to 1.14 g m⁻² day⁻¹. The catholyte recirculation for catholyte mixing resulted in a positive net energy production (NEP) of 0.227 ± 0.025 kJ day⁻¹. Those results have demonstrated the benefits of both using mesh membrane and the new reactor design for algal collection with positive effects on improving IPB performance.

在这项工作中，研究了集成光生物电化学系统（IPB）的创新设计和基于聚酯网膜（MM）的藻类收获方法。藻类的生长/收获期为6天，导致最高的表面生物量生产力（SBP）为0.88 g m ^-2  day ^-1和最高的能量产生为0.157±0.001 kJ day ^-1。在一个操作周期中（使用三个MM）的3次收获频率将SBP提升至1.14 g m ^-2  day ^-1。用于阴极电解液混合的阴极电解液再循环产生了0.227±0.025 kJ天^-1的正净能量产生（NEP）。这些结果证明了使用网膜和新的反应器设计进行藻类收集的好处，对改善IPB性能具有积极的作用。
