Analysis on the Influence of the Standard Curve of Dry Weather on the Quantitative Evaluation of RDII for Sewage Pipe Network
A quantitative assessment was conducted on the phenomenon of rainwater inflow during rainy days in the sewage pipeline network,and the impact of selecting the standard curve for dry days on the quantitative results was dis-cussed.Based on online monitoring methods,100 days monitoring data of 14 plots were obtained to achieve quantitative analysis of incoming rainwater(RDII)in sewage pipelines.At the same time,four different dry weather standard curves were used as benchmark data for calculation,and the differences in RDII results were analyzed.The results indicate that the selection of benchmark data can lead to differences in the quantitative calculation results of RDII;It is a reasonable choice to use the monitoring data of the"recent dry day of the week"as the benchmark data for analyzing RDII;The QV detection results are basically consistent with the evaluation results based on monitoring data,proving the reliability of the monitoring and evaluation method.
