Chemical Oxygen Demand (COD) is one of the core indicators for assessing the degree of organic pollution in water quality monitoring. It can quickly reflect the total amount of reducing substances (mainly organic matter) in water. It, together with BOD5, constitutes an important basis for judging the biodegradability of water samples and the effectiveness of wastewater treatment processes.

This article systematically introduces the definition of COD, determination principles, national emission standards, and how to achieve efficient and stable continuous detection through online monitoring technology. It focuses on recommending NiuBoL NBL-WQ-COD integrated online COD sensor, which adopts double wavelength ultraviolet absorption method, providing a reagent-free, fast-response reliabl···

COD (Chemical Oxygen Demand) and BOD (Biochemical Oxygen Demand) are core indicators for assessing organic pollution in water quality monitoring and wastewater treatment. COD reflects the total amount of chemically oxidizable organic matter and some inorganic reducing substances in water. BOD reflects the oxygen required by microorganisms to degrade organic matter.

Ammonia Nitrogen refers to the total nitrogen in water existing in the form of free ammonia (NH₃, non-ionic ammonia) and ammonium ions (NH₄⁺). It is one of the important parameters in water quality monitoring and wastewater treatment, directly related to eutrophication control, aquatic organism protection and wastewater treatment process optimization.
