Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a new water collecting nozzle for a biofiltration device which has a simple structure and is capable of being fitted to a floor plate by performing the fitting work only from the floor plate. SOLUTION: This water collecting nozzle 10 consists of a cylindrical nozzle bush 12 to be buried in a floor plate 3 and a dome stem 18 formed by integrating a nozzle dome 14 that is inserted into and fixed to the inside of the nozzle bush 12 and placed on the upper side of the floor plate 3 with a nozzle stem 16 placed on the lower side of the floor plate 3. Since the collecting nozzle 10 consists of the above two components, the nozzle 10 can easily the manufactured and handled. Since the dome stem 18 can unidirectionally be inserted into the nozzle bush 12 and fixed to it, the fitting work is also facilitated.
