摘要
为查找影响深圳水源地水质总氮含量超标的因素,文章以西丽水库为例,对境外引水、主要地表径流和雨水总氮含量进行监测。实验结果表明水库总氮含量超标主要是由于境外引水总氮含量高所致,但是降雨和地表径流也对总氮含量超标有一定影响。建议水源管理部门从境外引水的调度方案、水源保护区管理和增加水库库容等方面采取有效措施,降低水库总氮含量。
In order to find the reason of total nitrogen over the criteria in Shenzhen water sources,as example,Xili reservoir was investigated by monitoring its external diversion,slope runoff and rainwater.The result show that external diversion made a main contribution to the concentration of total nitrogen in reservoir.Measures were also proposed to control the concentration of total nitrogen.
