Denitrification achieve the purpose that denitrogenation；O (Oxic) is aerobic section, is removed by the metabolic activity of aerobic microbiological in water
Phosphorus-containing matter and other organic matters in water.Disadvantage is as follows: capital expenditure is slightly higher；Occupied area is bigger than normal；Operational administrative is complicated.
4, filler is arranged in traditional biological contact oxidation method in pond, and the sewage being oxygenated submerges whole fillers, and with certain flow velocity
Filler is flowed through, biomembrane is covered on filler, sewage is purified under the action of biofilm microorganisms.Disadvantage is as follows: as run
Improper, filler may block；Water distribution gas distribution should not be uniform；Denitrogenation dephosphorizing ability is poor.
