Deep filtration device for rural sewage treatment

Abstract

This utility model relates to a deep filtration device for rural sewage treatment, including a workbench and a filter assembly mounted on the workbench. Two support rods are fixedly installed at both ends of the workbench surface, and a top plate is installed above the support rods. The filter assembly includes a filter chamber, a granular tank, and a central rod. Two central rods are provided, with one central rod positioned between the two support rods at the ends of the workbench. The central rods are fixedly installed on the workbench surface. The granular tank and filter chamber are movably mounted on the workbench surface. The granular tank is located below the filter chamber and is rectangular in shape. The four ends of the granular tank are respectively fitted onto four support rods. A rotating rod drives a screw to rotate, lifting the granular tank and filter chamber, facilitating the removal of the filter chamber and replacement of the granular media in the granular tank by the operator, thus reducing the risk of structural damage to the tank.
