摘　　要：给水系统是一项重要的城市公共服务设施,藻类滋生引起的水质污染问题对城市居民的健康危害极大。针对藻类污染问题,文中综述了环境因素与藻类生长的相互关系,以及藻类对水源地、净水构筑物、供水管网、二次供水设施及其水质的影响,总结了传统控藻方法的特点及局限性,分析了新型控藻技术的应用现状。在此基础上,提出了一套既能减少藻细胞破坏,又能控制整个给水系统藻类生长的建议,为上海市及其他地区的给水系统藻类控制提供指导作用。Water supply system is an important urban public service facility,and water pollution caused by algae breeding is a great hazard to health of inhabitants.According to the problem of algae pollution,the paper summarizes the relationship between environmental factors and algal growth,and algae breeding effect on water sources,water purification structures,feed piping,secondary water supply facilities and their water quality.Afterwards,characteristics and limitations of traditional algae control method,and the application of new algal control technology are reviewed.Based on above,a set of suggestions is proposed to reduce the damage of algal cells and simultaneously control algae growth in the whole water supply system.This study can provide a guiding role for algae control in water supply system in Shanghai and other areas.
