摘要
提出了一种基于电渗析离子转型的水质氨氮检测方法,并基于可编程逻辑控制器和虚拟仪器技术设计开发了一套在线测控系统。可以通过上位机实现对装置的操控以及运行状态的监控,同时还具备对检测数据的实时采集、分析、显示以及存储功能。本装置测量氨氮满足在线分析测试的要求,且具有自动化程度高、操作简单方便、无需添加任何化学试剂、不产生二次污染等优点,因此具有良好的推广和应用价值。
A method of detecting ammonia nitrogen in water was presented, which was based on electrodialysis ion transition, and a set of on-line measurement and control system was designed based on PLC and LabVIEW. The system can realize the control of the device and the monitoring of its running status through upper computer. Meanwhile, it also has the functions of acquisition, analysis, display and storage for the real-time data-. When detecting ammonia nitrogen, the device meets the requirements of online analysis, and it also has the advantages of high level of automation, easy operation, no need to add any chemicals, no secondary pollution and so on. Therefore, it has a great value of promotion and application.
