Abstract

Abstract

To quickly investigate the overflow pollution pattern of urban rivers and to estimate the total pollution amount in complex urban areas, a calculation method based on monitoring data is proposed, which considers a closed region as a whole: Based on the balance relationship between domestic sewage volume, rainwater volume entering the sewage system, treated volume of the wastewater treatment plant, and overflow volume in the region, the overflow pollution is calculated by combining the monitoring data of pollutant concentration and flow, and further used to summarize the overflow pattern according to the rainfall data. The results show that based on 60 rainfall data, flow and water quality monitoring data during 458 days, the deviation between the calculated results and the monitoring results is +11.7%, and the accuracy of the results is acceptable. This method does not need to pay attention to the complex drainage network in the region, and the calculation and analysis is fast and reliable to support water environment planning and early stage of river water environment engineering.
- monitoring data,
- river water environment,
