Abstract

The invention relates to the technical field of sewage treatment, and in particular relates to a circular settling tank which comprises a tank body, water inlets, water outlets, sludge settling plates and a sludge settling barrel, wherein a plurality of layers of sludge settling plates are available, the water inlet and the water outlet are respectively formed at the upper side of each sludge settling plate, and the water inlets and the water outlets are formed along the tangential direction of the tank body. According to the circular settling tank, water passes into and out of the circular settling tank along the tangential direction, so that sewage can circulate in the circular settling tank, the standing time of the sewage in the circular settling tank can be prolonged, and the sedimentation effect of the sludge can be improved; furthermore, the plurality of layers of sludge settling plates are available, equivalently, a plurality of groups of settling tanks are additionally arranged, so that the sludge settling area is enlarged under the condition of the same occupied land area, and the settling efficiency is greatly increased; furthermore, the vertical distance between every two layers of sludge settling plates is shorter, so that particles with smaller particle sizes can be settled, and the sedimentation effect is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a circular multilayer sedimentation. Background technique [0002] At present, the suspended matter in the sewage can be precipitated and removed under the action of gravity, and at the same time, part of the BOD can be removed 5 , improve the operating conditions of biological treatment structures and reduce BOD 5 load. Precipitation process is a physical treatment method, which is simple and effective, and is one of the important technologies for sewage treatment. According to the direction of water flow in the tank, the sedimentation tank can be divided into horizontal flow sedimentation tank, radial flow sedimentation tank and vertical flow sedimentation tank. [0003] 1. Straight flow sedimentation tank [0004] The advection sedimentation tank is a rectangular sedimentation tank. The water flow direction is from one side of the sedimentation tank to the other s...
