摘　　要：文章通过调研实际居民小区二次供水水池(箱)在不同温度下的余氯衰减速率情况,发现其随水温增加呈现明显上升规律且差异逐渐扩大。结合二次供水水池(箱)的水龄余氯衰减关系方程,得出水龄和进口余氯浓度的控制目标。同时,对水厂、管网及二次供水多个环节的余氯优化给予优化策略建议,从而为上海高品质饮用水供水目标的实现提供技术支撑。The chlorine attenuation rate variation in the secondary water supply pool(tank)by researching different resident districts was investigated in this paper.Results showed that the chlorine attenuation rate had a significant increase and dffered significantly with increasing temperature.With the formula of water age-chlorine attenuation,the controlling objective of water age and chlorine concentration was obtained.Meanwhile,proposals for optimizing the distribution of chlorine in water treatment plants(WTPs),pipeline and secondary water supply were made to provide technical support for realization of high-quality water goal in Shanghai.
