二次供水定义及相关水质指标探讨

Discussion on Definition of Secondary Water Supply and Indicators Related to Water Quality

该文就《二次供水设施卫生规范》(GB 17051-1997)中二次供水的定义及二次供水水质相关指标进行了研究探讨,并对完善二次供水的定义及二次供水水质相关指标提出了建议和修改意见,同时按照《生活饮用水卫生标准》(GB 5749-2006)要求,采用其中的二次供水定义方式,作为区分二次供水与非二次供水的划分标准,从而实现《二次供水设施卫生规范》(GB 17051-1997)与《生活饮用水卫生标准》(GB 5749-2006)的统一与衔接。

The definition of secondary water supply and its facilities and indicators related to water quality in the Hygienic Specification for Facilities of Secondary Water Supply （GB 17051-1997 ） were discussed in this paper. Recommendations on improving the definition of secondary water supply and its facilities and suggestions on indica- tors related to water quality were proposed. Based on the requirements in the Standards for Drinking Water Quality （ GB 5749-2006） , the definition of secondary water supply in this standard was suggested to be used in distinguis- hing secondary water supply and non-secondary water supply. Therefore, a unified hygienic standard for drinking water would be realized by the connection and engagement of the Hygienic Specification for Facilities of Secondary Water Supply （GB 17051-1997 ） with the Standards for Drinking Water Quality （GB 5749-2006）.
