With the difference of organic component in water, the maximum absorption wavelength is not the same; there is obviously difference with UV full wave absoption spectrum and with different UV spectrum character in different type of wastewater. Fixed COD through Deuterium UV-VIS ber spectrometer system to nish the spectrum scan of full-wave band. Model neural network for each different water sample separately, and convert the COD parameter exactly by spectrum turbidity interference technology.
Widely used in environment monitoring, water and water conservancy monitoring, city sewage pipe network, ocean water monitor- ing, aquaculture, industrial process monitoring. The range of application for industrial wastewater including but not limited to: sewage treatment industry, chemical industry, petrochemical industry, medical industry, brewing industry and other relative industry.
