摘要:
道路雨水在城镇雨水资源化利用中拥有巨大潜力，但是其初期水质较差。作为一种雨水分流手段，初期雨水弃流装置能有效分离初期雨水和后期雨水。在分析已有弃流装置特点的基础上提出了一种新型容积-流量型雨水弃流装置，并开展了针对性设计及效果评估。结果表明：弃流装置的弃流过程与降雨过程有关，选定弃流标准为考虑2 mm路面填洼损失量后30 min降雨产生的径流量；在试验条件下，满足弃流标准的弃流管直径与降雨强度呈对数关系；弃流装置对SS的弃流效果最好，而对NH4+-N、NO3--N、TP及COD的弃流率相对较低，且装置的弃流效果与相关研究中其他类型弃流装置的效果基本一致。
Abstract:
Stormwater collected on road has huge potential in the process of urban stormwater resource utilization. However, the quality of most stormwater is poor in the initial stage. As a diverting means, the initial stormwater diverting device can effectively separate the initial stormwater and the later stormwater. This paper proposed a new volume-runoff stormwater diverting device based on the analysis of the existing diverting device characteristics, carried out the specific design, and evaluated the performance. The diverting process of the device was related to the rainfall process, and the diverting standard was the runoff generated by rainfall in 30 minutes after considering the loss of 2 mm pavement filling rainfall. Under the experimental conditions, the diameter of diverting pipe meeting the diverting standard was logarithmically correlated with the rainfall intensity. The device had the best diverting performance on SS, while diverting rates of NH4+-N, NO3--N, TP and COD were relatively low. In addition, the performance of the device was basically consistent with the conclusions of other types of diverting devices in related studies.
