<p>PURPOSE:To provide a device for efficient treatment of aerobic waste water containing a high percentage of suspended material. CONSTITUTION:A reactor 1 consists of introducing waste water and allowing it to pass through a sludge bed 7 based on aerobic microbes using an ascending stream. In this reactor, a reaction part 6 with a waste water introduction pipe 2 and a sludge bed 7 is provided at the bottom and a three-phase separation part 3 which separates the waster water into gas, solid and water at the top. An umbrella member 9 which opens downward is provided in the reaction part 6 at the top of the sludge bed 7. At the same time, a gas guide pipe 12 which guides the gas captured by the umbrella member 9 to the three-phase separation part 3 and an extraction pipe 10, which extracts a liquid containing a suspended material, located at the top of the umbrella member 9 are connected to the top of the umbrella member 9.</p> |
