Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage solid-liquid separation structure. Background Art

[0002] Sewage usually contains a large amount of solid matter such as suspended particles, plankton and organic matter. If these solid substances are directly discharged into the water body, it will cause water pollution and damage the aquatic ecosystem. In addition, the presence of solid substances will also cause difficulties in subsequent treatment processes. Therefore, it is very necessary to separate the solid substances from the liquid in the sewage through solid-liquid separation.

[0003] The existing referenceable Chinese utility model patent with announcement number: CN203400544U discloses a sewage solid-liquid separation structure, which includes a dam body for intercepting sewage and a filtering area arranged on the dam body, wherein the filtering area is a groove arranged along the flow direction of the water body, and the groove includes a front side wall directly impacted by the water flow and a left side wall and a right side wall located on both sides of the front side wall, and the left side wall and the right side wall are respectively provided with mechanical grilles. By using the solid-liquid separation structure described in the utility model, the efficiency of solid-liquid separation can be improved, and the pressure of deformation of the mechanical grille can be alleviated to a certain extent.

[0004] The existing sewage solid-liquid separation structure generally intercepts solids in the sewage through a filter. This method will cause solids that cannot pass through the filter to accumulate in the filter, causing the filter to be blocked. In addition, the existing solid-liquid separation structure is generally very inconvenient to salvage manually. Utility Model Content
