| titleOfInvention | Nitrogen and Phosphorus removal, recovery apparatus and method thereof |
| abstract | The present invention relates to a nitrogen and phosphorus removal and recovery apparatus and method thereof, and more particularly, to a primary MAP reaction tank for inducing a primary MAP reaction to generate MAP crystals through MAP reaction; A solubilization tank to which a sludge containing MAP crystals and SS and particulate matter remaining in the first MAP reaction tank is introduced and a solubilizing device for converting particulate phosphorus to dissolved phosphorus; A degassing vessel for converting the ammonium ion in the effluent into an ammonia state capable of being degassed and for discharging the treated water from which the phosphorus and nitrogen have been removed when the effluent flows through the membrane filter in the first MAP reaction tank; An alkaline scrubbing tower in which deaerated ammonia gas flows in the degassing vessel and caustic soda (NaOH) is added to deodorize the ammonia; An acid scrubbing tower in which ammonia gas is introduced from the alkaline scrubbing column and ammonia is removed by injecting sulfuric acid or an aqueous phosphoric acid solution; A zeolite reaction tank in which ammonium sulfate or ammonium phosphate discharged from the acid scrubber is introduced and ammonium is replaced with zeolite to adsorb and remove ammonium ions; Mg 2+ eluted from zeolite and phosphoric acid from ammonium phosphate are introduced into the zeolite reaction tank, and the sludge converted into the particulate phosphorus and the MAP crystals flow together while passing through the solubilization tank, A second MAP reaction tank capable of inducing a MAP reaction and growing MAP crystals generated in the first MAP reaction tank; And a collecting and separating device for collecting MAP crystals having a predetermined size or greater generated and grown while passing through the first and second MAP reaction tanks. |
