Abstract

Abstract

On-site investigation of sewage outfalls connected to watercourses is labor-intensive,and real-time tracking is hard to be performed manually.Facing with this challenge,an inverse problem method to trace source location and sewage flow based on hydrodynamic diffusion wave model and the microbial genetic algorithm was developed.The developed method was verified with a hypothetical example of sudden wastewater discharge and a real investigation case of sewage discharges into a river.The study results showed that:1) for the tracking of sudden wastewater discharge in large quantity,the inverse problem model could estimate source parameters including source location,source flow rate,starting and ending time of discharge effectively.After multiple runs of modeling,the median values of inversed source parameters were almost identical to the real ones.2) for the routine investigation of sewage outfalls,the developed method could identify the locations and discharge amounts of potential multiple sewage sources accurately,through the rational layout of hydrologic monitoring stations.3) for either the tracking of sudden wastewater discharge or the routine investigation of sewage discharges,the sewage outfall could be located to a spatial grid resolution of fewer than 200 m using the inverse modeling,on condition that the monitoring stations were set up with a spatial interval of 2000 m.Therefore,the developed inverse model could provide a technical solution for dynamic monitoring of sewage outlets connected to rivers in the future,with the support of online data.
