Used orthogonal double grating structure and designed an optical filter structure, the stray light in the incident light was eliminated. Designed a more stable and reliable COD detection device and provided a guarantee for the monitoring of pollutants and traceability technology. UV absorption detection method of COD is a simple physical method that can detect water samples online without secondary contamination from chemical reagent. In this paper, the detection of COD based on UV absorption method was studied. The UV absorption method was used to detect COD in water samples, and the COD online detection device was designed.
Optical path and circuit design principle of the device were introduced to overcome the difficulties including weak signal and the output signal instability, and the size of the system was effectively reduced.
