Composite biological filter for rural decentralized wastewater treatment

Abstract

The utility model discloses a kind of composite biological filter for rural decentralized sewage treatment belongs to sewage treatment field, including box and sealing door, the lower part of box interior is fixedly connected with partition, the upper portion of partition is rotatably connected with rotating plate, the upper surface of box interior is fixedly connected with baffle in two sides of middle part, the upper portion of rotating plate and the side of baffle abut, the upper portion of box is fixedly connected with water inlet pipe, water inlet pipe is located in the middle part of box upper portion, the lower part of box is fixedly connected with Y type pipe, the upper portion of Y type pipe is communicated with the lower part of box in two sides of middle part, in the scheme, rely on bilateral filtering area and adjustable rotating plate, when one side filter screen and filter tank ceramsite filter material layer appear block after long time use, purification efficiency drops, without shutdown, by adjusting rotating plate make sewage completely switch to the other side filtering area, equipment continues to process sewage, avoid the shutdown problem caused by single filter screen because long time filtration needs maintenance.
