portable water quality dissolved oxygen meter
Biochemical oxygen demand is also called biochemical oxygen demand. The abbreviation BOD in English (biochemical oxygen demand) is a comprehensive indicator of the content of aerobic pollutants such as organic matter in water. The total amount of dissolved oxygen in the water consumed during the mineralization or gasification is expressed in ppm as mg / liter. The higher the value, the more organic pollutants in the water, the more serious the pollution. Hydrocarbons, proteins, oils, lignin, etc. that are present in suspended or dissolved state in industrial wastewater such as sugar, food, paper, and fiber are organic pollutants that can be decomposed by the aerobic biochemical action Because oxygen is consumed in the decomposition process, it is also called aerobic pollutants. If such pollutants are discharged into the water body too much, it will cause a lack of dissolved oxygen in the water. At the same time, the organic matter will cause decomposition by the decomposition of anaerobic bacteria in the water. smell.
