<p>PROBLEM TO BE SOLVED: To provide anaerobic treatment equipment with upward flow which can securely and effectively carry out the separation of a generated gas and the precipitation of a granule, and enables high-efficiency treatment of organic wastewater. SOLUTION: This anaerobic treatment equipment with upward flow is provided with an upper gas collector in which a gas collector for collecting a gas is formed in a double structure of lower gas collecting hoods and upper gas collecting hoods located at a certain interval above opening portions each serving as an upward circulation flow path of a lower gas collecting hood, and a lower gas collector haing substantially the same structure as the upper gas collector, therebelow. Current plates with a predetermined height are protrusively provided at least along a longitudinal direction of the top parts of lower gas collecting hoods of the lower gas collector, respectively, to make the space between the lower gas collector and the upper gas collector a rectifying zone.</p> |
