[0003] Engineering practice has found that after the water distribution flower wall is installed in the pre-sedimentation tank, the water flow through the water distribution flower wall still needs a long adjustment to make the water flow velocity in the pre-sedimentation tank uniform, and the water flow behind the water distribution flower wall is disturbed. Poor, affecting the sedimentation effect of the water flow in the pre-sedimentation tank

The invention relates to a diamond-shaped perforated water distribution flower wall and a rectification method for a pre-sedimentation aeration tank of a water intake pump station, including an incoming water delivery pipeline and a pre-settling tank, and the incoming water delivery pipeline is connected with the entrance of the pre-settling tank. There is a first diamond-shaped hole with a splash wall at the entrance of the sedimentation tank, and a second diamond-shaped hole with a splash wall in the pre-sedimentation tank. The distance between the second diamond-shaped hole with a splash wall and the first diamond-shaped hole with a splash wall is the pre-settling 0.1 times the length of the pool, the height of the first diamond-shaped hole with water flower wall and the second diamond-shaped hole with water flower wall are both 0.56 times the width of the pre-sedimentation tank; the first diamond-shaped hole with water flower wall is provided with several vertical diamond-shaped perforations , the second rhombic hole with water spray wall is provided with horizontal rhombic perforations, and the plurality of vertical rhombic perforations are staggeredly distributed on the first rhombic hole with water splash wall. Through the present invention, the flow velocity distribution of the water flow in the pre-sedimentation tank can be made more uniform and smooth, and the settling effect of suspended matter such as sediment and other solid particles can be improved.
Description
technical field [0001] The invention relates to a diamond-shaped perforated water distribution flower wall for a pre-settled aeration tank of a water intake pump station and a rectification method thereof, belonging to the technical field of water conservancy engineering design. Background technique [0002] The pre-sedimentation tank is an important part of the water intake pumping station, and it plays an important role in the settlement of the suspended solid particles of the sediment. When the water flows from the water source into the pre-settling tank by itself through the pipeline, the water contains a large amount of suspended solids such as sediment. In order to make the suspended solids such as sediment settle in the pre-sedimentation tank as much as possible, it is necessary to ensure that the The water flow is smooth and uniform, and a perforated flower wall is usually set at the front end of the pre-sedimentation tank for water distribution.
