Abstract

With increasing urbanthe social development, improving the water quality has becoming a major challenge. The deterioration of drinking water quality is usually caused by long-distance water delivery and secondary water supply, as chlorinated water reaches standard of GB. In order to improve the water quality, studying the change of water quality in the water distribution network (WDN) is essential. Besides water deteriorates during the flow, the stagnant water in the dead-end brstranch pipes also diffuses contaminant into the main pipes.
This paper considered the ferrous ions, which accumulated at the dead-end branch pipes of WDN, as pollution sources, and studied the concentration of ferrous ions in the main pipes caused by the ferrous ions in main pipes using numerical simulation analysis. Results indicated that the correlation between the concentration of ferrous ions in the main pipes and the length of the dead-end branch pipes, the concentration of ferrous ions in the dead-end branch pipes, the flow velocity of the main pipes, the diameter of the main pipes as well as the diameter of the dead-end branch pipes. The experiment device was conductedused to verify the numerical model. In addition, the correlation has been used to improve the water quality model of EPANET software and was applied used in an actual WDN to evaluatefind the differences. The results shown that the improved software software has resulted in good performance
