摘　　要：水源水质是决定城市供水水质的关键性因素,影响着居民龙头水品质。研究发现,水源切换对二次供水耗氧量(锰法)、硝酸盐氮等指标影响显著,部分水质指标包括浑浊度、耗氧量(锰法)等指标在水源切换后达到上海市地标的要求。通过分析金泽水源切换前后上海市西南供水区域的二次供水水质的变化,可为水源切换后城市供水系统运行管理提供技术支持。Water quality of raw water determines the water quality of municipal water supply,effecting the water quality of tap water.Research results showed that water source switch had a significant effect on water quality indices including oxygen consumption(manganese)and nitrate nitrogen.Some water quality parameters including turbidity and oxygen consumption(manganese)reached the standard of Shanghai City water requirement.This paper analyzed water quality of the secondary water supply before and after water source switch,which could provide technical support for municipal water system running and management.
