Description

Technical Field

[0001] The utility model relates to the technical field of water treatment equipment, in particular to a central steady-flow clarifier. Background Art

[0002] The clarifier is a highly efficient water treatment facility that integrates mixing, flocculation reaction, and sedimentation functions. The water treatment facility has a sludge internal reflow function, which is comparable to the advanced and efficient sedimentation tanks introduced from abroad. It has the advantages of small footprint, high water purification efficiency, and low energy consumption. The separation of mud and water in the water treatment process is the key control point in water treatment technology, and it is also a difficult control point. It is easily affected by various factors, such as water body density flow, short flow, biased flow, and changes in water volume and water quality during actual operation.

[0003] A Chinese patent publication (publication number: CN219231522U) discloses a clarifier with a steady-flow water collection device, wherein a plurality of water collecting troughs distributed along the circumference of the clarifier body are arranged above the clarifier body, and slots are opened on the two side walls of the water collecting troughs. Furthermore, it also includes a water collecting branch pipe, and a plurality of water collecting branch pipes are arranged between each water collecting trough, and the bottom height of the water collecting branch pipe is higher than the bottom height of the water collecting trough. The clever design of this product can ensure that the flow patterns of water in each part of the clarifier are the same, avoid short-flow, bias flow, and reduce the generation of heterogeneous flow. However, in actual use, the sewage entering the first reaction chamber lacks obstruction. When the water flow is unstable, it is easy to bring the sludge at the bottom of the clarifier into the first reaction chamber, reducing the clarification effect. For this reason, a clarifier with a central steady flow is proposed. Utility Model Content
