Summarize

COD refers to, under a certain condition, the correspondent mass concentration of oxygen needed in the process of potassium dichromate consumption by the reducible substance oxidized by strong oxidant potassium dichromate in the water, which is represented by mg/L of oxygen. COD can represent the pollution level of the water that is polluted by reducible substances, which involve organics, nitrite, ferrite and sulfide, and so on.
