微塑料(MPS)已被证明是废水处理系统的主要威胁之一。然而，MPS对微藻废水处理技术的影响尚不清楚。研究了聚氯乙烯(PVC)、聚丙烯(PP)和聚乙烯(PE)对微藻去除人工猪场沼气中氮磷的影响。结果表明，聚氯乙烯颗粒大小对微藻生长有显著影响。聚氯乙烯含量、PP颗粒大小和含量、PET颗粒大小和含量对微藻生长的影响均不显著。微藻对氨氮的去除受聚氯乙烯颗粒大小和含量、PP颗粒大小和含量的影响显著，而PET颗粒大小和含量对氨氮去除的影响均不显著。三种MPS的颗粒大小和含量对总磷的去除均有显著影响。微藻细胞被MPS吸附后结合在一起，增加了胞外聚合物的分泌，影响了氨氮和总磷的去除。
Microplastics (MPs) have been proven to be one of the major threats to the wastewater treatment system. However, the impact of MPs on microalgae-based wastewater treatment technology are still unknown. In this study, effects of polyvinyl chloride (PVC), polypropylene (PP), and polyethylene (PE) on the removal of nitrogen and phosphorus from synthetic piggery digestate by microalgae were investigated. Results show that the effect of PVC particle size on the growth of microalgae was significant. The effects of PVC content, PP particle size and content, PET particle size and content on the growth of microalgae were all not significant. The removal of ammonia nitrogen by microalgae was influenced significantly by PVC particle size and content, PP particle size and content, the effects of PET particle size and content on the removal of ammonia nitrogen were all not significant. The effects of particle size and content for three MPs on the removal of total phosphorus were all significant. Microalgae cells were bound together after being adsorbed by MPs, which increased the secretion of extracellular polymers and influenced the removal of ammonia nitrogen and total phosphorus.
