The present invention relates to a wastewater treatment apparatus for shortcut nitrogen removal using anaerobic ammonium oxidation (ANAMMOX) and partial nitritation using ammonium oxidizing bacteria (AOB) granules. High-purity AOB granules are formed by means of AOB predominance using a side stream generated during a sludge treatment process. Moreover, the formed AOB granules are supplied to a partial nitritation tank (130) of a main treatment process and thus the partial nitritation is efficiently performed and nitrogen is quickly removed, and thus oxygen and an organic material is reduced compared to an existing method.

NITROGEN-RICH WASTEWATER TREATMENT APPARATUS USING PARTIAL NITRITATION SEQUENCING BATCH REACTOR TANK LINKED TO AMMONIUM OXIDIZING BACTERIA GRANULE PRODUCTION TANK AND ANAEROBIC AMMONIUM OXIDATION
The present invention relates to a nitrogen-rich wastewater treatment apparatus using a partial nitritation sequencing batch reactor (SBR) tank, ammonium oxidizing bacteria (AOB) granules and anaerobic ammonium oxidation (ANAMMOX). AOB granules can efficiently be formed by means of a sludge exchange between the SBR tank and an AOB granule production tank. Moreover, partial nitritation is performed by means of allowing the AOB granules to flow into the SBR tank again, nitrogen is quickly removed by means of ANAMMOX without a supply of an external carbon source, and oxygen and an organic material are reduced and a sludge yield decreases compared to an existing method.
A pivoting gas/liquid dissolution device according to the present invention comprises: a dissolution case; an introduction port provided outside the same; a gas/liquid separation inducing means provided inside the same such that introduced dissolution water and insoluble gas are separated; and a discharge port provided outside the dissolution case. The introduction port comprises an introduction tube connected to the dissolution case, an insertion tube inserted into the same, and an intake tube connected to the insertion tube. The discharge port is structured to have a discharge channel formed therein so as to communicate with the interior of the dissolution case. The gas/liquid separation inducing means comprises a first gas/liquid separation guide tube which contacts the discharge-side front end surface of the dissolution case, and which is spaced from the opposite-side front end surface of the dissolution case, and a second gas/liquid separation guide tube configured such that one end thereof is spaced from the discharge-side front end surface of the dissolution case, and the other end thereof contacts the opposite-side front end surface of the dissolution case. The first gas/liquid separation guide tube and the second gas/liquid separation guide tube have guide channels formed therein, respectively, such that the insoluble gas is separated from the dissolution water and then flows. According to the present invention, different kinds of soluble gases can be easily injected through the intake tube. Therefore, the gas dissolution performance is improved, and the insoluble gas separating function is also improved, making it possible to effectively generate dissolution water containing microbubbles and to prevent the insoluble gas from degrading the status of flow of the dissolution water.
A wastewater treatment apparatus comprises a biofiltration tank, a nitritation tank, and an anammox tank. The biofiltration tank performs a biofiltration process on the inflowing wastewater as a pretreatment process to remove solids and organic substances. The nitritation tank performs a nitritation process on the wastewater flowing in from the biofiltration tank and returns some of the wastewater to the biofiltration tank, thereby supplying electron acceptors necessary for removing organic substances. The anammox tank receives wastewater from the biofiltration tank and the nitritation tank and performs an anaerobic ammonium oxidation process on the wastewater.
