PROCESSING APPARATUS AND PROCESSING METHOD OF NITROGEN CONTAINING SEWAGE

PROBLEM TO BE SOLVED: To provide a processing apparatus and a processing method of nitrogen containing sewage, in which a carrier on which an anammox bacteria group is attached and fixed is held, granules of the anammox bacteria group are effectively formed, and which can be installed in a short period and perform high-speed processing.SOLUTION: A processing apparatus 10 of nitrogen containing sewage includes: a culture section 4 for an autotrophic ammonia oxidizing bacteria group arranged in a lower part of a reaction tank 1 and a sewage processing section 5 arranged in an upper part of the tank 1, the sewage processing section containing the autotrophic ammonia oxidizing bacteria group supplied from the culture section 4 and the nitrogen containing sewage. In the culture section 4, the autotrophic ammonia oxidizing bacteria group is attached and fixed on a carrier and the carrier is made of a thermoplastic polyurethane resin whose main component is polyethyleneglycol.SELECTED DRAWING: Figure 1 【課題】アナモックス細菌群が付着固定化された担体が保持され、アナモックス細菌群のグラニュールが効果的に形成され、短期間で立ち上げられ、且つ高速で処理可能な窒素含有廃水の処理装置及び処理方法の提供。【解決手段】本発明の窒素含有廃水の処理装置１０は、同一反応槽１内において、前記反応槽１の下部に、独立栄養性アンモニア酸化細菌群の培養部４と、前記反応槽１の上部に、前記培養部４から供給された前記独立栄養性アンモニア酸化細菌群と窒素含有廃水とを含む廃水処理部５と、を備え、前記培養部４において、前記独立栄養性アンモニア酸化細菌群が担体に付着固定化されており、前記担体がポリエチレングリコールを主成分とする熱可塑性ポリウレタン樹脂からなる。【選択図】図１
