Preliminary Exploration of the Correlation between Various Indicators of Nitrogen in Water
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.
