An anammox reactor capable of improving nitrogen removal efficiency by maintaining activity of microorganisms, and a water treatment method using the anammox reactor are provided. The anammox reactor includes a raw water feed pipe through which raw water is supplied, a raw water discharge pipe through which raw water is discharged to an outside, and a first chamber configured to accommodate ammonium oxidizing bacteria (AOB) and anammox bacteria for performing an anammox process, wherein the raw water feed pipe and the raw water discharge pipe are configured to communicate with the first chamber.

Anammox reactor and water treatment method using the same

A water treatment apparatus for removing nitrogen in raw water and a water treatment method using the same are provided. The water treatment apparatus includes a denitrification reactor configured to remove nitrogen contained in raw water supplied thereto, a phosphorus treatment tank configured to remove phosphorus (P) contained in the raw water supplied from the denitrification reactor, an anammox reactor configured to remove nitrogen contained in the raw water supplied from the phosphorus treatment tank through an anammox reaction, a partial nitritation tank configured to convert ammonium ions (NH) remaining untreated in the anammox reaction into nitrite ions (NO), and a sedimentation tank configured to cause settling of suspended matter contained in the raw water supplied from the partial nitritation tank so that sludge forms and discharge the raw water through a raw water discharge pipe.
