Examples
Referring to fig. 1, a novel sewage filter material 11 backwashing device comprises a backwashing pump 2 connected with a filter tank 1 through a connecting pipeline, wherein an air washing pipeline 3 is communicated with the connecting pipeline, a water inlet main valve 221 is arranged on the connecting pipeline, an air inlet main valve 33 is arranged on the air washing pipeline 3, and the air washing pipeline 3 is positioned on one side of the water inlet main valve 221 away from the backwashing pump 2; wherein, the air washing pipeline 3 can be connected with an external aeration fan. By adopting the structure, through installing the air washing pipeline 3 on the connecting pipeline, namely, the air washing is added on the basis of water washing, the filter material 11 is alternately washed in two washing modes, so that the backwashing effect of the filter material 11 is greatly improved, the pollution and blockage are reduced, and the sewage treatment efficiency is improved.
In this embodiment, the number of the backwash pumps 2 is 2, the connecting pipeline comprises two water inlet branch pipes 21 and a connecting main pipe 22, each backwash pump 2 is connected with one water inlet branch pipe 21, the two water inlet branch pipes 21 are connected through the connecting main pipe 22, the water inlet main valve 221 is arranged on the connecting main pipe 22, and the air washing pipeline 3 is connected on one side of the connecting main pipe 22 far away from the backwash pump 2.
