| 摘 要： | 考察了黄河下游某市给水管网水质的生物稳定性。结果表明:2011年2～7月,生物可同化有机碳AOC在8.7～328.7μg/L,81.3%的检测数据AOC<100μg/L,其值随季节变化、水温升高而升高。AOC P17在AOC组成中占优势,季节变化特征较AOC NOX明显。以引黄水库作为水源、处理工艺不同的两水厂给水管网可生物降解溶解性有机碳BDOC存在差异。黄河下游城市给水管网水质生物稳定性总体水平较好,管网不同取样点细菌再生长限制性因子有差异,AOC、磷及其他无机营养元素均有可能成为限制性因子。

| Abstract: | This paper studied the biological stability in drinking water distribution network of a city located in the downstream region of Yellow River.The results showed: from Feb.2011 to July 2011,the assimilable organic carbon(AOC) varied between 8.7 μg/L to 328.7 μg/L,and the AOC in 81.3% measured data was less than 100 μg/L,AOC would increase with the change of season and water temperature.AOC-P17 was dominant in AOC components,and its seasonal characteristic was more apparent than AOC-NOX.There was difference between the biological dissolved organic(BDOC) in water distribution networks of two water treatment plants with the raw water from Yellow River but different process.The biological stability in the water distribution network of the city located in downstream region of Yellow River was in a good condition generally,the bacterial regrowth limiting factors varied in different sampling sites in network,AOC,phosphorus,and other inorganic nutrient might become the limiting factors. |
