鞍山市重要水质站水质分析与评价

Analysis and evaluation of water quality of important water quality stations in Anshan City

地表水国家水质站的水质反映了国家重要江河湖泊水资源的基本情况,因此对重要水质站的水质进行监测分析与评价是必不可少的。本文通过连续流动分析法分别检测了鞍山市三岔河、文家街、张荒地大桥、岫岩、高家、海城等重要水质站水质在丰水期(7—9月)、平水期(10—11月)以及枯水期(12月—次年2月)高锰酸盐指数(CODMn)、氨氮(NH3-N)、总磷(TP)以及总氮(TN)的浓度,通过单因子水质标识指数法和综合水质标识指数法,计算得出6个监测断面水质的主要污染因子均为TN,综合水质均较好,除TN外,其余指标基本上均能达到其对应的辽宁省水功能区水质目标。

The water quality of surface water national water quality stations reflects the basic situation of water resources of important rivers and lakes in China,so it is necessary to monitor,analyze and evaluate the water quality of important water quality stations. In this paper,the water quality of Sanchahe,Wenjia Street,Zhanghuangdi Bridge,Xiuyan,Gaojia,Haicheng and other important water quality stations in Anshan City was measured by continuous flow analysis method in the periods of high water( July-September),normal water( October-November) and low water( December-February) It is calculated that TN is the main pollution factor of the water quality of the six monitoring sections,and the comprehensive water quality is good. In addition to TN,other indicators can basically reach the water quality target of the corresponding water function area in Liaoning province.
