Abstract

An anaerobic suspension-bed reactor for biologically treating sewage is composed of a biologic reaction unit whose main component is a biologic reaction tower with water distributor and three-phase separator, and a marsh gas circulation unit consisting of march gas buffering cabin, pneumatic pump and gas distributor.

Description

technical field [0001] The invention relates to an anaerobic biological treatment equipment for organic waste water, in particular to an anaerobic biological reactor for biogas circulation and effluent backflow. Background technique [0002] The anaerobic expansion or fluidized bed reactors currently used in the prior art use effluent backflow to increase the hydraulic rising flow rate in the reactor, so that the granular sludge is in an expanded or fluidized state in the reaction zone. Most of the organic matter in the wastewater is removed when it flows through the granular sludge bed area, and converted into methane and carbon dioxide. The upper part of the reactor is equipped with a three-phase separator, and the effluent is discharged after gas-liquid separation and precipitation, and the biogas is also discharged after collection. . The effluent backflow promotes the expansion or fluidization of the granular sludge bed: ① It can reduce the blockage of the bed and avoi...
