摘要： 为了响应国务院颁布的《水污染防治行动计划》，实现2035年市政自来水直饮的目标，本文对上海某老旧小区的二次供水管网进行模拟。根据管网布置现状，提出了3个不同的管网布置方案，对其进行模拟，比较各点水龄、压力、流速等水力情况。选取较为合适的改造方案：现状和方案1，并分别对其进行水池水位和管网管径优化。模拟结果显示水池水位优化和管网管径优化方案可以显著缩短水龄，压力和流速均处于较合适的范围，根据模拟结果多维度比选，最终选取基于水池水位与管网管径优化的现状管网。经检测，改造后各项水质指标检测均达标，余氯衰减系数降低了53.3%。

Abstract: In response to the "Water Pollution Prevention and Control Action Plan" promulgated by the State Council and to achieve the goal of direct drinking of municipal tap water in 2035, the secondary water supply net- work of an old community in Shanghai is simulated. According to the current pipeline network layout, three other different pipeline network layout schemes are proposed, which are simulated to compare the water age, pressure, flow rate and other hydraulic conditions at each point. Choosing a more appropriate transformation plan and comparing the current situation and planned one, the water level of the pool and the diameter of the pipe network are respectively optimized. The simulation results show that the water level optimization and pipe diameter optimization of the pool can significantly shorten the water age, and the pressure and flow velocity are in a more appropriate range. According to the simulation results, the multi-dimensional comparison and selection are finally selected based on the current situation of the optimization of the water level of the pool and the pipe diameter. After testing, all water quality indicators are up to standard after the renovation, and the residual chlorine attenuation coefficient is reduced by 53.3%.

Key words: direct drinking water, renovation plan, hydraulic model, water age
