| 摘 要： | 通过对七星关区倒天河不同河段水质实验分析,采用行业标准方法检测水质污染:悬浮物、pH、氨氮、总磷等指标。了解该河流冬季受污染的现状,为城市地表河流治理提供相关科学依据。结果表明:倒天河在天河水库出口附近,氨氮和总磷指标表征水环境分别为Ⅰ类和Ⅱ类水质,符合生活用水相关标准,之后污染总体上呈加重趋势,河流并未出城已受人类活动污染为Ⅴ类水质。

| Abstract: | Through experimental analysis to water quality of Daotian Stream sections,provide scientific basis for the management of river.Detection quality index of polluted water with the standard methods,including suspended solids,pH,ammonia nitrogen,total phosphorus.Results：NH3-N and total phosphorus of the stream is of class Ⅰ and Ⅱ quality nearby the reservoir.It meets the related standards of living water.As the stream is down,pollution is aggravated gradually.The pollution grade is of Ⅴ class before the stream is throughout city because of effects coming from human activities. |

| Keywords: | Daotian Stream total phosphorus ammonia nitrogen pH suspended solids reason analysis |
