Abstract :
Oxygen is one of the prominent parameters characterized the quality of water, how to detect the precise content of oxygen is paid much attention nowadays. Lately the method of fluorescence quenching has been the hotspot practice to detect the oxygen in the international. This paper based on the principle of fluorescence quenching has designed the DO(dissolved oxygen)detecting system. Through choosing dissolved oxygen sensing head and photoelectric receiving devices rationally and determining appropriate circuit parameters after experiment, it can realize the detecting of the DO preliminarily, laying the foundation for the instrumentation of the system.
