摘要
通过对珠海市前山河流域 2019-2023 年国、省控站点断面采测分离数据的分析可知,氨氮和总氮的比值整体满足总氮/氨氮=3.4159 氨氮-0.8435,该比值主要受氨氮含量的控制;珠海市前山河流域的氨氮含量自 2019 年后整体呈下降趋势,且均优于地表水三类标准,总氮含量则存在波动,建议后期将治理重心放在总氮的削减上.
Abstract
The analysis of the separation data collected from national and provincial control stations in the Qianshan River of Zhu hai from 2019 to 2023 shows that the overall ratio of ammonia nitrogen to total nitrogen meets the requirement of TN/NH3-N=3.415×NH3-N-8.435,and the ratio is mainly controlled by the NH3-N;the ammonia nitrogen content in the Qianshan River has shown an overall downward trend since 2019 and is better than the three types of surface water standards.However,there are fluctuations in total nitrogen content.It is recommended to focus on reducing total nitrogen in the later stage of treatment.
