    Peripheral Water Quality Analysis from Pipe Networks in Some Districts of Shanghai in 2010-2014

      摘要
    • 摘要:
      目的 了解该区管网水质状况和变化趋势，为监管对策的制定提供数据支撑。
      方法 收集该区管网末梢水监测数据，运用Excel 2007和SPSS 20.0对其进行分类汇总和统计分析。
      结果 2010年-2014年管网末梢水质监测的整体合格率44.2%，各年依次为50.0%、34.8%、26.4%和71.7%（P < 0.05），春夏秋冬四季的合格率依次为35.4%、40.0%、56.2%、45.6%（P < 0.05），月度分布中合格率后3位的分别是8月（31.4%）、1月（33.3%）和4月（34.0%）；管网水的8项监测指标中，耗氧量和锰在年度和季度分布均有差异（P < 0.05）；所有不合格监测指标项次数构成中位列前3位的分别是耗氧量（72.6%）、锰（17.6%）和菌落总数（6.1%）。
      结论 该区管网末梢近5年水质状况变化较大，但近3年来有变好趋势；应重点加强对春季的水质以及耗氧量和锰的监测，进一步改善水质。

       

      Abstract:
      Objective To understand the status and changing trend of the quality in peripheral water from water pipe networks as well as to provide suggestions for supervision.
      Method The data were collected and classified by Excel 2007 and analyzed by SPSS 20.0.
      Results The overall qualified rate was 44.2% and the annual qualified rate in 2010-2014 was 50.0%, 34.8%, 26.4% and 71.7%, respectively (P < 0.05), the seasonal qualified rate was 35.4%, 40.0%, 56.2% and 45.6%, respectively (P < 0.05). The water quality in August (31.4%), January (33.3%) and April (34.0%) was the worst. Only oxygen consumption and manganese content among 8 monitoring indexes were different (P < 0.05) annually and monthly; the top three unqualified monitoring indexes were oxygen consumption (72.6%), manganese content (17.6%) and total bacteria counts (6.1%).
      Conclusions The quality of peripheral water fluctuated strongly in recent five years, the quality has become better in recent three years.We should focus on strengthening supervision in the Spring as well as put emphasize on reducing oxygen consumption and manganese content to further improve water quality.
