A process of reinforcing the denitrification efficiency of an anaerobic ammoxidation reactor by utilizing a spongy iron filler

A process of reinforcing the denitrification efficiency of an anaerobic ammoxidation reactor by utilizing a spongy iron filler is provided. The process is characterized in that spongy iron is added into the reactor to increase the anaerobic ammoxidation denitrification efficiency. Through reduction, the spongy iron can remove dissolved oxygen or other oxidizing compounds possibly brought by raw water, and can eliminate inhibiting functions of the dissolved oxygen and the oxidizing compounds on anaerobic ammonium oxidation bacteria. The spongy iron plays a role on conversion and removal among ammonia nitrogen, nitrate nitrogen and nitrite nitrogen, thus reducing the total nitrogen in discharged water. Divalent ferrous ions and ferric ions which are dissolved out through a reaction from the spongy iron can be adopted as trace elements and supplied to microorganisms to promote physiological and biochemical reactions of the microorganisms, and generated ferric hydroxide floc can be adopted as a flocculating agent to promote formation of anaerobic granular sludge, thus reinforcing ammoxidation and increasing the removing rate of the total nitrogen. The process can be used for denitrification of domestic wastewater and can be used for denitrification of various types of nitrogen-containing industrial wastewater.
