発明の名称: (EN) ANAEROBIC WATER TREATMENT SYSTEM
要約:
(EN) An anaerobic water treatment system according to the present invention is provided with: an anaerobic reactor; a raw water supply unit; a granular sludge bed section; a gas solid liquid separation device; an overflow section; a guide pipe; and a downward flow generation device. The raw water supply unit is provided with: a raw water introduction pipe for introducing into the anaerobic reactor organic waste water as the raw water; and a raw water pump. The guide pipe has: an upper end which is open below a water surface defined by the overflow section; and a lower end which is open inside the granular sludge bed section. Furthermore the guide pipe has an introduction port of the raw water introduction pipe inserted therein from the opening at the upper end thereof such that said introduction port faces downward. The guide pipe guides into the granular sludge bed section the raw water introduced from the raw water introduction pipe. The downward flow generation device is fitted to a hollow section of the guide pipe and applies a downward propulsive force to the raw water introduced into the guide pipe to cause downward flow of the raw water in the guide pipe without increasing the discharge flow rate of treated water at the overflow section.
