运用氨氮变化形态进行水质预测分析研究

Research on Water Quality Prediction and Analysis Using Ammonia Nitrogen Change Patterns

摘要: 浙江省地表水交接断面水质自动监测站·滨海站是温岭市金清大港入海水质监测断面，也是温岭市重要的出境交接断面之一，目标水质是Ⅲ类。文章分析了该断面两个易超标因子氨氮和溶解氧的变化趋势，发现每一年滨海站氨氮均呈现“V + W”的变化形态，并尝试运用氨氮的变化形态进行水质预警。

Abstract: The Zhejiang Province Surface Water Transfer Section Water Quality Automatic Monitoring Station∙Binhai Station is a water quality monitoring section at the estuary of Jinqing Dagang in Wenling City, as well as one of the important outbound transfer sections in Wenling City. The target water quality is Class III. The article analyzes the trend of changes in two easily exceeding factors, ammonia nitrogen and dissolved oxygen, in this section. It is found that the ammonia nitrogen at Binhai Station shows a “V + W” change pattern every year, and attempts to use the change pattern of ammonia nitrogen for water quality warning.
