生物处理法是污水处理领域的核心技术，其中的生物膜法因具有耐冲击负荷、污泥产量少、运行管理方便等优势，已在全球范围内得到广泛关注。生物膜载体作为微生物附着生长材料，在生物膜处理工艺中起到关键作用，直接影响工艺的处理效果。然而，目前所开发的生物膜载体大多只能为微生物提供适宜稳定的生态位，并不具有强化污水处理效果的能力。为此，本文围绕五种能够提高污染物降解效率的新型生物膜载体(缓释生物膜载体、氧化还原介体生物膜载体、磁性生物膜载体、亲水改性生物膜载体、亲电改性生物膜载体)进行讨论，详细阐述了其具体分类与作用机理，并针对其今后研究方向与未来发展提出建设性建议，以期为未来大范围提标改造污水处理厂提供理论参考。
Current research status of novel biofilm carriers in wastewater treatment
Biological treatment process is a core technology in the field of wastewater treatment.Among them,the biofilm method has been widely concerned due to some advantages,such as impact resistance,low sludge yield,and operation as well as management convenience.As the microbially attached growth material,biofilm carriers play a crucial role in the biofilm treatment process and directly influence the treatment effect.However,most of the currently developed biofilm carriers can only provide suitable and stable ecological niches for microorganisms,lacking the ability to enhance wastewater treatment effectiveness.Therefore,this paper focuses on five novel biofilm carriers(slow-release biofilm carrier,redox mediator biofilm carrier,magnetic biofilm carrier,hydrophilic modified biofilm carrier,and electrophilic modified biofilm carrier)that can improve pollutant degradation efficiency.It discusses their specific classifications and mechanisms,and gives some suggestions for future research directions,in order to provide a theoretical reference for promote the large-scale upgrading of wastewater treatment plants.
