李家河水库水源地水质分析

The Monitoring of Water Quality in Lijiahe Reservoir

通过对总硬度、水质高锰酸盐指数(CODMn)、氟化物、六价铬、氨氮、硝酸氮、盐硫酸盐等7个水质指标的监测,并对照《地表水环境质量标准》(GB 3838-2002)标准,对李家河水库上游水源地水质进行了分析和评价.结果表明:李家河水库上游水源地三处水样监测的指标大部分满足地表水环境Ⅱ类水相关标准,除两河桥和红门寺水样的CODMn指标超标外,总体水质良好.

Based on the monitoring of seven water quality indicators such as total hardness, CODMn, fluoride, six chromium, nitrate nitrogen, ammonia nitrogen, and sulfate salt, an anal- ysis and evaluation of the water quality of Lijiahe Reservoir is given by referring to ＂Surface Water Environment Quality Standard＂ （ GB3838 - 2002）. The result shows that the three water samples from the upstream water sources mostly meet the relevant standards of surface water Grade II. Except for the parameters in terms of CODMn from Two River Bridge and Hongmen Si samples, which exceed the standard indexes, the water quality is generally good.
