Anoxic treatment is effective for COD, with a removal rate of 50%; aerobic treatment and Fenton’s process have little effect thereafter. The COD level in the inlet water is around 3000, it drops to 1500 after anoxic treatment, and further decreases to 1400 after aerobic treatment

What is the water volume? What is the formaldehyde content?
