- Abstract:
- This paper investigated the characteristics of water chemical stability in a multi-source water supply network in a southern city, and identified the water quality sensitive areas of the water supply network. The data of residual chlorine, turbidity and total iron from 20 sampling points of the city from March 2019 to March 2021 were selected to analyze the water quality characteristics of the pipeline network in different regions and seasons. The water quality of the water supply network in the city was overall good, and the water quality sensitive areas were mainly located at the end of the water supply network, the old urban areas and some water supply demarcation points, which should be paid attention to in the process of water supply dispatching. There was a negative correlation between turbidity and residual chlorine, and the increase of turbidity was related to the release of iron-containing pollutants in the inner wall of the pipeline.
