[0020] like Figure 1 As shown, this utility model provides a wastewater treatment station for cleaning filter media, including a raw water tank 1. The raw water tank 1 is connected to an inclined tube sedimentation tank 3 through a primary water inlet control device 2. An inclined tube packing 19 is provided in the middle of the inclined tube sedimentation tank 3, and a perforated sludge discharge pipe 20 is provided at the bottom of the inclined tube sedimentation tank 3.

[0021] The outlet of the inclined tube sedimentation tank 3 is connected to a material interception filter 4. A carrier plate 5 is installed inside the material interception filter 4. The periphery of the carrier plate 5 is in contact with the inner wall of the material interception filter 4. A cable 6 is installed on the carrier plate 5.
