biochemical oxygen demand
Molecular formula :
MW :
CAS :

nature : short BOD. Water pollution level of a target. As the organic matter is the role of microbial oxidation caused by the consumption of the total amount of dissolved oxygen in water, mg / liter said. Complete oxidation of organic very long time, the testing standards at 20 ° C for five days of oxygen consumption as their representatives, referred BOD5, when the BOD oxidation rate of about 80%. China's factories discharge wastewater BOD5 maximum allowable concentration of 60 mg / liter, the BOD5 surface water should be less than 4 mg / liter.
