NIPGA法快速连续检测污水氮含量的可行性研究

The feasibility research for detecting the nitrogen content in sewage quickly and continuously with NIPGA

为了快速、连续检测污水中的总氮含量,采用了NIPGA技术,用D-D中子发生器作为产生中子的中子源,使用BGO探测器测量了N元素的特征γ射线.模拟结果表明:在N元素的检测限为0.2mg/L,可以检测Ⅴ类水中的总氮含量.此方法可以用于污水中总氮含量的快速、连续监测.

NIPGA technology is adopted in order to detect the total nitrogen content in sewage quickly and continuously. The neutron source is selected and used D-D neutron generator, using BGO generator to detect gamma rays of nitrogen. The simulated result shows the nitrogen＇s limit of detection is 0.2 mg/L and the total nitrogen in V-type water can he detected. So this method can he used to detect the total nitrogen content in sewage quickly and continuously.
