某市新建工程二次供水水箱设计对水质卫生状况的影响

Design of secondary water supply tank in a new city influence on water quality

目的:了解某市新建工程的二次供水卫生学现状,为进一步完善生活给排水相关规范要求提供依据。方法:2013年和2014年对新建工程项目验收前的二次供水及二次供水设施进行抽样检验和卫生学评价。结果:二次供水设施中生活水箱设计合理的二次供水微生物指标合格率95.1%,理化指标合格率95.5%;设计不合理的二次供水微生物指标合格率60.4%。理化指标合格率88.7%。结论:新建工程二次供水设施还应进一步加强设计阶段的规范管理。

Objective:To understand the current situation of secondary water supply projects in a new city,and to provide basis for further improvement of water supply and drainage.Methods:Sampling inspection and hygienic evaluation on the secondary water supply and the secondary water supply facilities before the acceptance of the new project in2013and2014.Results:In the secondary water supply facilities,the microbial indicators qualified rate of secondary water among those reasonable facilities was95.1%,and the qualified rate of physical and chemical indexes was95.5%;among those unreasonable design facilities,the qualified rate of microbial index was60.4%,and the physical and chemical indicators pass rate was88.7%.Conclusion:Secondary water supply facilities in the new construction should strengthen the standardized management of the design stage further.
