Sedimentation tank and sewage treatment device

Abstract

The invention relates to a sedimentation tank and a sewage treatment device. The sedimentation tank comprises a tank body and a plurality of sedimentation pieces, and the sedimentation pieces are arranged in the tank body in the depth direction of the tank body and are used for dividing the inner space of the tank body into a plurality of water passing spaces; when the sedimentation pieces are positioned at a first position; the inclination angle of the sedimentation pieces relative to the tank body is marked as a first angle, so that sedimentation mud in the sewage is settled to the sedimentation pieces when the sewage flows through the water passing spaces, the plurality of sedimentation pieces are combined to form a sedimentation pieces assembly; the sedimentation pieces tank also comprises water blocking pieces; when the sedimentation pieces are positioned at the second position, the inclination angle of the sedimentation pices relative to the tank body is marked as a second angle;therefore, the sedimentation mud is separated from the sedimentation pieces by virtue of gravity and falls into the bottom of the tank body; the plurality of sedimentation pieces are combined to forma sedimentation assembly; the sedimentation tank comprises water blocking pieces, when the sedimentation pieces are located at the second position, one end of the sedimentation assembly protrudes outof the surface of the sewage, and the other end of the sedimentation assembly abuts against the end, close to the top of the tank body, of the water blocking pieces, so that the sedimentation assembly and the ends, close to the top of the tank body, of the water blocking pieces jointly form a blocking structure.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a sedimentation tank and a sewage treatment device. Background technique [0002] Due to the relatively deep depth of the traditional sedimentation tank, the sludge in the sewage interacts with the sewage water body for a relatively long time before falling into the bottom of the tank, which will cause the sediment to settle to the bottom of the tank It was mixed into the sewage water body again by the excessive impact of the sewage water body before, resulting in low sedimentation efficiency of the sediment in the sewage water. Contents of the invention [0003] Based on this, it is necessary to provide a sedimentation tank and a sewage treatment device capable of improving the sedimentation efficiency of sediment in sewage. [0004] A sedimentation tank, comprising: a pool body and a plurality of sedimentation parts, the pool body is used to accommodate sewa...
