| abstract | (57) [Abstract] [Objective] In a dephosphorization device that removes phosphorus in phosphorus-containing wastewater as magnesium ammonium phosphate crystals by adding an alkaline agent, the MAP particles produced are effectively coarsened, and the alkaline agent is added. Prevent blockage of inlet. [Structure] A magnesium ammonium phosphate crystal of a reaction tower 1 is provided with an addition portion 6 of an alkali agent below a deposition layer. [Effect] The alkaline agent becomes a turbulent flow in the upward flow of the raw water and is rapidly stirred, and instantaneously becomes a uniform liquid and rises in the reaction tower. A uniform pH range suitable for MAP precipitation is set as a whole, MAP is efficiently produced at every place in the reaction tower, crystallization occurs on the surface of MAP particles, and MAP particles are produced and coarsen. . By uniformly diffusing the injected alkali agent, the retention of the alkali agent in the vicinity of the injection port is prevented and the clogging of the injection port by the MAP scale is also prevented. |
