The effect of addition of algae to activated sludge as active biomass in membrane bioreactors (MBRs) and electro-MBRs (e-MBRs) for wastewater remediation was examined in this study. The performances of Algae-Activated Sludge Membrane Bioreactor (AAS-MBR) and electro Algae-Activated Sludge Membrane Bioreactor (e-AAS-MBR) were compared to those observed in conventional MBR and e-MBR, which were previously reported and utilized activated sludge as biomass. The effect of application of electric field was also examined by the comparison of performances of e-AAS-MBR and AAS-MBR. Similar chemical oxygen demand (COD) reduction efficiencies of AAS-MBR, e-AAS-MBR, MBR, and e-MBR (98.35 ± 0.35%, 99.12 ± 0.08%, 97.70 ± 1.10%, and 98.10 ± 1.70%, respectively) were observed. The effect of the algae-activated sludge system was significantly higher in the nutrient removals. Ammoniacal nitrogen (NH₃−N) removal efficiencies of AAS-MBR and e-AAS-MBR were higher by 43.89% and 26.61% than in the conventional MBR and e-MBR, respectively. Phosphate phosphorous (PO₄³⁻-P) removals were also higher in AAS-MBR and e-AAS-MBR by 6.43% and 2.66% than those in conventional MBR and e-MBR. Membrane fouling rates in AAS-MBR and e-AAS-MBR were lower by 57.30% and 61.95% than in MBR and e-MBR, respectively. Lower concentrations of fouling substances were also observed in the reactors containing algae-activated sludge biomass. Results revealed that addition of algae improved nutrient removal and membrane fouling mitigation. The study also highlighted that the application of electric field in the e-AAS-MBR enhanced organic contaminants and nutrients removal, and fouling rate reduction.

在这项研究中，研究了将藻类添加到活性污泥中作为膜生物反应器（MBRs）和电MBRs（e-MBRs）中用于废水修复的活性生物质的影响。将藻类活化污泥膜生物反应器（AAS-MBR）和电藻类活化污泥膜生物反应器（e-AAS-MBR）的性能与传统MBR和e-MBR的性能进行了比较，之前已报道并使用了活性污泥作为生物质。还通过比较e-AAS-MBR和AAS-MBR的性能来检验电场施加的效果。与AAS-MBR，e-AAS-MBR，MBR和e-MBR相似的化学需氧量（COD）降低效率（分别为98.35±0.35％，99.12±0.08％，97.70±1.10％和98.10±1.70％）被观察。藻类活性污泥系统在去除营养物方面的效果明显更高。氨氮（NHAAS-MBR和e-AAS-MBR的_3- N）去除效率分别比常规MBR和e-MBR高出43.89％和26.61％。与传统的MBR和e-MBR相比，AAS-MBR和e-AAS-MBR中的磷（PO ₄ ^3- -P）去除率也分别高6.43％和2.66％。AAS-MBR和e-AAS-MBR的膜污染率分别比MBR和e-MBR降低了57.30％和61.95％。在含有藻类活化污泥生物质的反应器中还观察到较低浓度的结垢物质。结果表明，藻类的添加改善了养分的去除和膜污染的缓解。该研究还强调指出，电场在e-AAS-MBR中的应用增强了有机污染物和营养的去除，并降低了结垢率。
