- Abstract:
- Water samples collected from the transmission pipeline (approximately 40 km) between JZ reservoir and SP waterworks were detected, and the changes of water quality were analyzed aimed at the problem of water quality safety in long-distance water transmission. In the process of water transmission, the typical water quality indexes such as ammonia nitrogen decreased by approximately 40%, permanganate index decreased, but turbidity and total number of bacteria increased. In addition, the pretreatment effects of different methods (chlorination/activated carbon addition) on raw water were compared, and the results showed that the pretreatment effects of raw water were similar.
