摘要
氨氮浓度是水污染物质中的一项重要指标。该文着重介绍了基于紫外光吸光度原理的在线水质氨氮分析仪的工作原理及构成，并对实验数据进行了紫外光吸光度与氨氮浓度的数学建模。该分析仪主要应用于地表水、河水、废水的监测，与传统的仪器相比该仪器具有速度快、可靠性高、使用成本低等优点，将成为在线水质氨氮检测的主要设备。
The concentration of Ammonia nitrogen is an important indicator of sewage water contaminants. The paper focuses on the description of the working principle and composition of an on-line water quality ammonia nitrogen analyzer which is based on the theory of Uhraviolet Light Absorbance. On the basis of experimental data, the mathematics modeling between ultraviolet Absorbance and Ammonia concentration is analyzed. The analyzers are mainly applied to monitoring surface water, river and wastewater. This new analyzing technology is of being faster, simpler, more reliable and cost efficient, compared with its conventional counterparts and it will become the principal on-line ammonia nitrogen detector for water quality analysis.
