１項記載の装置。[Scope of Claim for Utility Model Registration] (1) Forming pellet-like granules starting from seed sludge through self-propagation granulation of anaerobic microorganisms in a slowly upward flow area of high-concentration organic wastewater in a treatment tank, In the equipment of the upflow anaerobic treatment method, which treats the upflow wastewater by contact treatment by retaining granule concentrated in the lower layer of the upstream flow area to form a biological bed with a high concentration of anaerobic microorganisms. An inclined plate is provided as a separation section for three-phase separation of sludge, liquid, and gas in the upper part of the tank, and the area of the upper opening opened at the lower end is 1/3 to 1/10 of the cross-sectional area of the treatment tank. A small parallel auxiliary inclined plate part is provided below the plate part at a distance from this part, its lower end is bent downward, and the opening between it and the gas deflector part below is set to the minimum area necessary for sludge discharge. A gas and suspended matter separation device for an upflow anaerobic treatment tank, characterized in that: (2) When the processing tank is cylindrical, the apparatus according to claim 1, wherein the sub-inclined plate part is formed into a center-symmetrical funnel shape including the downwardly bent part at the lower end. .
