Manufacturers of COD monitoring equipment for water quality


The wide application of COD online monitoring technology has positive and far-reaching significance for real-time monitoring of water pollutants. China should realize the development goal of total control of water pollutants. It will be the general trend to establish a perfect COD on-line monitoring system and improve the quality monitoring ability. The cod monitoring equipment independently developed by JINGxun Unimpeded can monitor water quality quickly and accurately, which is conducive to better understanding of water quality of relevant departments and enterprises in need of COD monitoring.

Introduction of cod monitoring equipment for water quality

Chemical oxygen demand (COD) is a chemical measure of the amount of reductant substances in a water sample that need to be oxidized. The oxygen equivalent of substances (generally organic substances) that can be oxidized by strong oxidants in effluents, wastewater treatment plant effluents and effluents. In the study of river pollution and industrial wastewater properties and sewage treatment plant operation management. It is an important and rapid determination of organic pollution parameters, often with COD as the symbol.

It is found that organic matter has the maximum absorption value in the ultraviolet region of 254 nm. So you can measure the absorbance at that wavelength. Suspended matter absorbs visible light at 900 nm, while organic matter absorbs almost nothing. Therefore, it can be divided into two light paths, and the COD value of water quality can be obtained by measuring the absorption degree of the two light paths.

Biological oxygen demand (BOD) refers to the dissolved oxygen consumed by aerobic microorganisms in the process of decomposing organic matter into inorganic matter in water. The size of this index indirectly reflects the quantity of organic pollutants in water. It is an important index of water pollution degree. Bod on-line monitoring equipment can be used for monitoring.
