- Abstract:
- The improvement of quality and efficiency is a long-term systematic project. In this context, the compilation of a special sewage plan must not only study the form of long-term sewage collection and treatment, but also fully consider the outlet of excess sewage in the near future, in order to control the overflow frequency. Taking the compilation of sewage planning in a town in Jiangsu as an example, under the background of quality and efficiency improvement of wastewater treatment, based on the analysis of the key issues of the current sewage systems, this study proposes the value of the short-term and long-term external water infiltration coefficient. This work could accurately predict the short-term and long-term sewage volume, thus, the sewage volume prediction is more in line with the actual situation, and plans of the sewage treatment facilities are more reasonable than those of traditional methods. In order to verify the current situation on the discharge capacity of the adverse-sloped sewage pipe network, the hydraulic model of the main sewage system is constructed using PCSWMM software to simulate the operation status of the sewage pipe network, which could guide the sewage system planning scheme, and improve the scientificity and feasibility of the sewage planning.
