- Abstract:
-
A 10- step research framework for improving municipal wastewater treatment quality and efficiency based on water quantity and quality monitoring and pipeline detection was established and supported by a sewage drainage system model. A pilot area of 2.6 km2 in a pilot city was studied and the downstream outlet node of sewage pipe network was selected as the key target node for improving quality and efficiency. Based on the established sewage drainage system model, the simulation analysis of water quantity and quality was carried out for 7 drainage network renovation scenarios. The results showed that the BOD5 concentration of the critical node will increase from 63.57 mg/L to the target value of over 100 mg/L under the renovation scenarios of key pipe network defects and outlet reconstruction in the region in the near future.
