Abstract

A bioreactor is provided to increase reaction efficiency by increasing separation efficiency of gas / liquid / solid. The bioreaction region (S) where sludge drifts is from around the central to the bottom part in the container (1). The raw water is anaerobicly bioprocessed in the bioreaction region (S), and then is directed to a separation device (4) disposed in the upper portion in the container (1) to separate gas / liquid / solid. The processed water that had been separated from gas / liquid / solid is drained out of the container (1) through a drain pipe (6). The solid component deposits in the gas / liquid / solid separation device (4) and returns in the bioreaction region (S) in the container (1) through the solid component drain pipe (7). The baffles (21) to (24) made of circular plates are arranged in the gas / liquid / solid separation device (4). The baffles (21) to (24) is taper-shaped in a manner the lower the diameter is the smaller the diameter is. The baffles (21) to (24) are separated from each other and are arranged in a concentric manner.

Description

technical field [0001] The present invention relates to a bioreactor suitable for biological treatment of wastewater, and in particular to a bioreactor with a gas-liquid-solid separation chamber on the top of a container for biological reactions. Background technique [0002] For a long time, UASB (Upflow Anaerobic Sludge Blanket, upflow anaerobic sludge bed) or EGSB (Expanded Granular Sludge Bed, granular sludge expanded bed) biological treatment device has been widely used in the biological treatment of organic drainage (biotreatment ). By performing these UASB and EGSB treatments, the organic substances in the wastewater are converted into methane and CO through anaerobic biological treatment. 2 gas. Therefore, the biologically treated water will contain gases (methane, CO 2 ), liquid (water) and solid (sludge). In order to efficiently perform UASB and EGSB treatment, gas-liquid-solid separation must be performed so that solid content does not flow out. [0003] In J...
