上海市某水厂水源水深度处理前后的水质变化

Water quality analysis before and after advanced treatment of source water in a water plant

  • 摘要:
    目的了解某水厂深度处理前后该地生活饮用水水质变化,为生活饮用水的水质管理提供科学依据。
    方法上海某水厂水源水深度处理前后,连续监测该水厂出厂水及相关的生活饮用水的水质。
    结果水源水深度处理前后综合合格率分别为81.7%、80.0%,差异无统计学意义;出厂水和末梢水处理前后综合合格率分别为50.6%、99.4%,差异有统计学意义(P < 0.05);深度处理前后出厂水、末梢水单项水质指标合格率:耗氧量为58.3%、100%,浑浊度为92.2%、100%,锰为90.0%、100%,菌落总数为96.7%、99.4%,差异均有统计学意义(P < 0.05);总大肠菌群为98.3%、100%,差异均无统计学意义。
    结论深度处理后,该地区水质得到明显改善;今后需重点关注微生物指标,进一步加强饮用水卫生监测。

     

    Abstract:
    ObjectiveTo investigate the changes of the quality of drinking water before and after advanced treatment of source water in a water plant, so as to provide the scientific evidence for management of the quality of drinking water.
    MethodsThe tap water and the same as drinking water were monitored and studied before and after advanced treatment.
    ResultsThe comprehensive qualified rate of source water before and after advanced treatment were 81.7% and 80.0% respectively, with no significant difference.The comprehensive qualified rates of the factory water and the end water before and after advanced treatment were 50.6% and 99.4%, respectively, with significant differences between the two conditions.The qualified rates of individual water quality indicators of the tap water and the end water before and after the advanced treatment were as follows:the oxygen consumption was 58.3%, 100%, the turbidity 92.2%, 100%, the manganese 90.0%, 100%, the total bacterial counts were 96.7% and 99.4% respectively, the difference was statistically significant(P < 0.05);the total coliform groups were 98.3%, 100%, the difference being without statistical significance.
    ConclusionThe water quality of the area has been greatly improved after advanced treatment; greater emphasis should be given to the index of microorganism and the hygiene of drinking water is further monitored.
