20100187187 | PLANT FOR AEROBIC AND ANAEROBIC DIGESTION TREATMENT BY PFR - Disclosed are a wastewater treatment plant and a wastewater treatment method. The wastewater treatment plant includes: a reactor including a gas outlet, a treated water outlet, and an inlet through which wastewater and gas are supplied, through which the wastewater is introduced, to perform aeration and denitrification; a sludge separation means including plural reaction unit bodies stacked inside the reactor to divide the interior of the reactor into upper and lower sides and separating sludge in a aeration process by forming a gas hold-up space for collecting the gas rising from a lower portion of the reactor; and a aeration unit introducing gas into the reactor. | 07-29-2010 |
20080264840 | Fluids Fluxion Method and Plant for Wastewater Treatment - A wastewater treatment plant includes a reaction tank connected to an wastewater supply tube and an aeration apparatus to receive wastewater therein, a sludge separation unit dividing an internal space of the reaction tank into upper and lower sections to increase an amount of dissolved oxygen by increasing an contact area of the wastewater and bubbles and to separate relatively light materials by moving low density matters existed on a surface of each section upward in turn, an air exhaust tube mounted on the reaction tank to exhaust bubbles passing through the sludge separation unit out of the reaction tank, a treated water exhaust tube mounted on the reaction tank to exhaust the wastewater that is treated by passing through the sludge separation unit, and a settling tank provided on a bottom of the reaction tank to concentrate and exhaust the settled sludge. | 10-30-2008 |
