Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and particularly relates to an effluent structure of a high-density sedimentation tank. Background Art

[0002] In recent years, the high-density tank technology has entered China and is mainly applied to the front-end process of the sewage treatment system and the water purification station system of power plants. To ensure the uniformity of the effluent and avoid the formation of turbulent flow caused by local high flow rates, the high-density tank usually leads out the water after sedimentation of the sludge through multiple effluent troughs. However, due to installation and uneven settlement, the effluent troughs of the high-density tank are not in the same plane, resulting in a high-level trough and a low-level trough. As a result, the effluent flow rate of the low-level trough is very large, while the effluent flow rate of the high-level trough is very small. Serious deviation of the flow causes serious sediment accumulation on one side of the horizontal flow area, and at the same time, the total water production decreases. When the flow rate is increased, the effluent quality of the low-level trough will exceed the standard. Content of the Utility Model

[0003] In view of the above existing technical problems, the utility model provides an effluent structure of a high-density sedimentation tank to solve the problem that the effluent of the existing high-density tank has uneven effluent volume, resulting in exceeding the effluent quality standard. The effluent structure of the high-density sedimentation tank has good effluent adjustability and ensures the uniformity of the effluent at different positions.

[0004] The utility model discloses an effluent structure of a high-density sedimentation tank, which includes a high-density sedimentation tank, a water inlet pipe, a sludge discharge pipe, and a plurality of effluent troughs. The water inlet pipe is connected to the middle part of the side wall of the high-density sedimentation tank, the sludge discharge pipe is connected to the bottom of the high-density sedimentation tank, a plurality of the effluent troughs are arranged in parallel at intervals on the top of the inner cavity of the high-density sedimentation tank, both ends of the effluent trough are respectively connected to the inner side walls on both sides of the high-density sedimentation tank, a water outlet pipe is led out from one end of the effluent trough, a plurality of water inlet holes communicating with the inner cavity of the high-density sedimentation tank are arranged at intervals along the extending direction of the side wall of the effluent trough, a baffle is arranged on the side wall of the effluent trough, and the baffle can move up and down along the side wall of the effluent trough to adjust the shielding degree of the water inlet holes.

[0005] Furthermore, a plurality of water inlet holes are arranged on both side walls of the effluent trough.

[0006] Furthermore, chutes penetrating up and down are arranged at both ends of the two side walls of the effluent trough, damping blocks are connected to both ends of the baffle, and the two damping blocks are respectively slidably arranged in the two chutes.

[0007] When the effluent structure of the high-density sedimentation tank is treating sewage, sewage is introduced through the inlet pipe, sludge is settled by introducing a flocculant, the sludge is discharged through the sludge discharge pipe, and the settled water is discharged through a plurality of effluent troughs. In order to ensure the uniform effluent of the plurality of effluent troughs, a plurality of water inlet holes are provided on the side wall of the effluent trough, and a baffle with adjustable height is used to partially cover the water inlet holes, so as to adjust the water inlet height and the effluent flow of each effluent trough, ensure that each effluent trough is in a relatively balanced state, ensure the stable operation of the high-density sedimentation tank, and avoid unilateral sludge accumulation.
