摘要
基于2003年以来西河水库中总氮、氨氮、硝酸盐氮等有关水质参数的变化,分析得出了水库中总氮呈逐年上升趋势和主要以硝酸盐氮为存在形式,并存在富营养化的潜在危机;从内部源和外部源对库中氮的来源进行了解析,得出氮主要来源于水库底泥、农业面源和生活污水的污染,进而提出相应的预防措施。
Based on the water quality parameters changes in Xihe reservoir since 2003,such as total nitrogen,ammonia nitrogen,nitrate nitrogen,it was found that total nitrogen was increasing year by year and nitrate nitrogen was the major form of total nitrogen. Simultaneously there was a potential risk of eutrophication. Then through the source apportionment of nitrogen from internal sources and external sources,it was obtained nitrogen was mainly from the reservoir sediment,agricultural nonpoint source and sewage pollution. Finally,the appropriate precautions was proposed.
