Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to an anaerobic wastewater treatment device which comprises an anaerobic tower, a rotational flow water distributor is arranged at the inner bottom of the anaerobic tower and comprises a cone and a connecting pipeline, a water inlet is formed in the top of the cone, and the connecting pipeline penetrates through the side wall of the anaerobic tower and is in sealed connection with the water inlet. A water collecting cavity is formed in the cone, a plurality of water distributing layers are arranged in the cone in the vertical direction, a first annular groove is formed in the top of the water collecting cavity, an annular plug body and a first spring are arranged in the first annular groove in a sliding mode, a second annular groove is formed in the top of the cone, and a plurality of adjusting channels are formed in the side wall of the connecting pipeline; a first connector and a second connector are arranged at the free end of the connecting pipeline, and an adjusting assembly is arranged on the second connector. The problems that in the prior art, the water outlet speed is difficult to adjust to the optimal state, and flowing-out sewage and sludge cannot be fully mixed, so that the sewage treatment efficiency of a reactor is low are solved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an anaerobic waste water treatment device. Background technique [0002] Upflow sludge bed-filter (UBF for short) is a new composite anaerobic fluidized bed reactor developed by Canadian Guiot on the basis of anaerobic filter and upflow anaerobic sludge bed. UBF reactor usually includes Water distribution area, granular sludge area, soft packing area, filter layer and three-phase separator and other parts. [0003] Most of the existing water distribution areas are equipped with swirl water distributors. Through the swirl water distributors, the sewage flowing out of the water distribution outlet forms a swirl water distribution in the granular sludge area at the bottom of the reactor, so that the sewage can be mixed with the sludge. Improve the treatment efficiency of the anaerobic reactor. [0004] However, at present, the water outlet flow rate of the swi...
