| 中文摘要: |
| 农村河道污染治理常面临设施短缺、污染负荷波动大、污染物时空分异性强等挑战，而生物膜法凭借其低成本、高效率和环境友好的优势，为农村河道水质净化与生态修复提供了可行的技术路径。本文系统解析了生物膜法的净化机理，重点综述了不同水质、流速及治理需求下适用于农村河道修复的三类生物膜工艺模式（固定载体型、悬浮载体型及生态复合型）；探讨了面向面源污染与点源-面源复合污染的工艺集成策略；进一步针对生物膜载体长期服役、工艺选型及成本评估等局限性，提出了未来的智慧工艺路径。 |
| 英文摘要: |
| The pollution control of rural rivers often faces challenges such as inadequate infrastructure, significant fluctuations in pollution loads, and pronounced spatio-temporal variability of pollutants. The biofilm method, recognized for its cost-effectiveness, high efficiency, and environmental friendliness, offers a viable technical approach for water purification and ecological restoration in rural river systems. This paper systematically examined the purification mechanisms of biofilm processes and provided a focused review of three types of biofilm technologies（fixed carrier, suspended carrier, and ecologically composite systems）suitable for rehabilitating rural rivers under varying water qualities, flow regimes, and treatment demands. Additionally, it discussed integrated strategies for managing non-point source pollution as well as combined point and non-point source pollution. Furthermore, considering limitations related to the long-term performance of biofilm carriers, process selection, and cost evaluation, the study proposed intelligent process pathways for future applications. |
