Description

Horizontal circulation anaerobic treatment device Technical Field The utility model relates to the technical field of water treatment, in particular to a horizontal circulation anaerobic treatment device. Background Anaerobic reactors are classified into up-flow anaerobic reactors and baffled (ABR) anaerobic reactors according to the flow state of sewage in the reactors. The sludge, water and gas of the upflow anaerobic reactor rise simultaneously, the sludge falls back to the reaction area at the lower part after three-phase separation, methane is collected and led out, water flow is discharged from the upper part after rising continuously, rising methane and water flow interfere the sludge falling down after separation to ensure that the sludge is not easy to fall back, so that the concentration of the sludge in the reaction area is unevenly distributed, and meanwhile, the density of the sludge is reduced to float upwards when the separation of the methane attached to the sludge is incomplete, so that the sludge is easy to run off along with water. The baffling anaerobic reactor separates muddy water and gas by arranging a baffle plate to make the muddy water and gas pass through up and down baffling for a plurality of times, the organic load gradually decreases along the water flow direction from the water inlet end to the water outlet end, but the sludge concentration gradually increases in a gradient way, so that the sludge load at the water inlet end is overlarge, the impact load resistance of the system is poor, the rancidity phenomenon is easy to generate, and the anaerobic system is damaged.
