摘　　要：针对当前曝气技术在黑臭水体治理过程中存在曝气设计不科学,曝气量、曝气时间及影响半径等参数设计不合理,与其他技术的耦合机理尚不明确等问题。先对曝气削减水体常见污染物的效果进行文献研究,明确曝气在黑臭水体治理中的有效性。其次,对影响曝气效果的因素进行综合分析,得出底部微气泡曝气在效果及能耗方面具有显著优势;曝气强度和曝气时间与污染物去除率三者间存在明显的相关关系;综合考虑能耗和效果,曝停比方面具有较大的优化空间等结论。最后对曝气与其他技术的耦合研究进行了概述和展望,以期为曝气技术治理黑臭水体提供理论参考。When treating black and odorous water bodies,the current aeration technology is faced with problems such as unscientific aeration design,unreasonable design of parameters such as aeration volume,aeration time,and influence radius,and unclear mechanism of coupling with other technologies.To solve these problems,this paper conducts a literature study of the effect of aeration in reducing common pollutants in water bodies and clarifies the effectiveness of aeration in the treatment of black and odorous water bodies.Then,factors affecting the aeration effect are comprehensively analyzed,and the following conclusions are drawn from the results.Bottom microbubble aeration has significant advantages in effect and energy consumption;clear correlations among aeration intensity,aeration time,and pollutant removal rate are observed;when energy consumption and effect are comprehensively considered,the room for optimization of aeration/non-aeration ratio remains large.Finally,an overview and prospects of the coupling study of aeration and other technologies are presented.This research is expected to provide a theoretical reference for the treatment of black and odorous water bodies with aeration technology.
