摘　　要：城市大型景观水体污染问题日益突出,净化补水或换水项目越来越多,但目前国内还没有针对城市大型景观水体净化工艺出水水质标准,现行一些水质标准由于侧重点不同,在大型景观水体美学、感观、生态健康等方面对水质的要求有些还没有具体化,确定城市大型景观水体补水或换水净化厂水质目标时,应根据水体的功能要求,有针对性地选择控制指标及限值。与饮用水厂和城市污水处理厂具有完善的建设标准不同,城市大型景观水体净化厂还没有形成较为成熟的模式和特点,因此景观水体净化厂处理工艺选择应遵循针对性、集成性和运行灵活性等原则。With the increasing pollution of urban large-scale waterscape, water supplement pro- jects with clean water or water change appear increasingly. However, there is no special treated water quality standard for urban large-scale waterscape, and existing water quality standards are not suitable be- cause they are lack of specified requirements on aesthetics, sense, ecological health and so on, which re- sults from different emphasises. When the water quality target for water treatment plants of supplement water or changed water for the urban large-scale waterscape is determined, control indexes and thresholds shall be chosen according to the waterscape function requirements. Different from facts that complete con- struction standards exist for portable water treatment plants and municipal sewage treatment plants, the mature model has not formed for water treatment plants for urban large-scale waterscape. So, they have their special characteristics. Water treatment process selection for waterscape shall obey the rules of perti- nence, integration, flexible operation and so on.
