丹江口水库总氮含量较高的调查分析

Analyse of high content of total-nitrogen in Danjiangkou Reservoir

通过对丹江口水库库区、河南省辖入库河流及其它水体含氮类指标的对比,对水库总氮偏高的原因加以分析,指出总氮标准与硝酸盐、氨氮标准有差异的问题,提出合理评价总氮指标及水库水质、加强水质保护措施的建议。

Through contrasting the contents of nitrogen indexs in Danjiangkou Reservoir, river entries in Henan Province and other similar water systems, this paper analyzed the cause of the high content of total-nitrogen in Danjiangkou Reservoir and pointed that it is discrepant in total-nitrogen's, nitrate nitrogen's and ammonia's standards. Then some rational suggestions of evaluating total-nitrogen, evaluating reservoir quality and intensifying the safeguards of water quality were put forward.
