There have been significant advances in the use of biological and physical selectors for the intensification of continuously flowing biological wastewater treatment (WWT) processes. Biological selection allows for the development of large biological aggregates (e.g., mobile biofilm, aerobic granules, and densified biological flocs). Physical selection controls the solids residence times of large biological aggregates and ordinary biological flocs, and is usually accomplished using screens or hydrocyclones. Large biological aggregates can facilitate different biological transformations in a single reactor and enhance liquid and solids separation. Continuous-flow WWT processes incorporating biological and physical selectors offer benefits that can include reduced footprint, lower costs, and improved WWT process performance. Thus, it is expected that both interest in and application of these processes will increase significantly in the future. This review provides a comprehensive summary of biological and physical selectors and their design and operation.
在使用生物和物理选择器强化连续流动生物废水处理（WWT）工艺方面已经取得了重大进展。生物选择有利于形成大型生物聚集体（例如，移动生物膜、好氧颗粒和致密化生物絮凝物）。物理选择控制大型生物聚集体和普通生物絮凝物的固体停留时间，通常使用筛网或水力旋流器来实现。大型生物聚集体可以在单个反应器中促进不同的生物转化，并增强液固分离。结合生物和物理选择器的连续流WWT工艺具有多种优势，包括占地面积减小、成本降低以及WWT工艺性能提高。因此，预计未来对这些工艺的兴趣和应用将显著增加。本综述全面总结了生物和物理选择器及其设计与运行。
