【摘要】 目的对新建二次供水设施工程进行卫生学评价,研究相关工程技术措施,为二次供水工程建设提供依据。方法依据国家相关规范标准,对相关项目的设计资料、现场调查情况、水质抽检结果等进行评价。结果大部分二次供水设施据初步评价建议进行了改善,经规范冲洗消毒水样抽检合格率100%。新、旧设施的水质检测结果比较,新设施水质显著提高:浑浊度2008年P<0.01、2009年P<0.01,耗氧量加08年P<0.01、2009年P<0.01。本文提出提升二次供水工程建设水平的相关技术措施。结论二次供水的卫生安全保障,设施的规范建设,有效的监管,非常重要,必须高度重视。更多还原

【Abstract】 Objective To provide the basis for the secondary water supply construction projects through the hygiene evaluation of the new secondary water supply projects and research the related engineering technologies and measures.Mothods According to the related national standards and norms,we evaluated the projects with their design imformations,field investigation and the results of water quality test.Results Most secondary water supply facilities were reformed and improved according to the suggestions in the pre-evaluation,and after standardizedly washed and sterilized the pass rate of the water samples is 100%.Comparing with the test results of the old facilities,the water quality of the new facilities raises obviouslyrturbidity with P<0.01(2008) and P<0.01(2009),oxygen consumption with P<0.01(2008) and P<0.01(2009).Through the study we propose the technologies and measures to improve the level of secondary water supply project construction.Conclusion Being important in ensuring the hygiene of secondary water supply,standardizedly construction of the facility and effective regulation should be paid serious attention on.更多还原
