[0016] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1~2As shown, the embodiment of the utility model proposes a system for collecting scum and aged sludge on the surface of a biochemical pool in a sewage treatment process, comprising a biochemical pool body 1, a lifting device, a bracket 2, a water spray pipeline 3 and a plurality of nozzles 4, wherein the biochemical pool body 1 is provided with a sewage inlet 5 and an overflow port 6, the water inlet 5 and the overflow port 6 are respectively located at both ends of the biochemical pool body 1, the lifting device is used to lift the bracket 2, the bracket 2 is arranged according to the shape of the biochemical pool body 1, the water spray pipeline 3 is connected to the water inlet pipe 7 of the water spray pipeline 3 through a telescopic hose, the telescopic hose can use a steel telescopic connecting pipe, the water spray pipeline 3 is fixedly connected to the bracket 2, the water spray pipeline 3 is arranged according to the shape of the biochemical pool body 1 and is located on the pool wall side of the biochemical pool body 1, the water spray pipeline 3 is also connected to a plurality of branches 8 arranged in parallel, the branch 8 is located in the middle of the biochemical pool body 1, and the nozzles 4 are evenly installed on the water spray pipeline 3 and the branch 8 for spraying and cleaning the pool wall and the ground of the biochemical pool body 1.

[0018] In this embodiment, if Figure 2 As shown, the lifting device includes a hydraulic cylinder 9 and a telescopic rod 10, the two ends of the telescopic rod 10 are respectively hinged on the bracket 2 and the ground of the biochemical pool body 1, one end of the hydraulic cylinder 9 is hinged on the ground of the biochemical pool body 1, and the other end is hinged on the outer tube of the telescopic rod 10.

[0019] The hydraulic cylinder 9 and the telescopic rod 10 are used in combination to push the bracket 2 up and down, thereby driving the water spray pipe 3 on the bracket 2 to move up and down. When cleaning the pool wall of the biochemical pool body 1, the hydraulic cylinder 9 is used to push the water spray pipe 3 up and down, so that the nozzle 4 on the water spray pipe 3 continuously cleans the biochemical pool body 1. When cleaning the ground of the biochemical pool body 1, the water spray pipe 3 is stopped at the bottom of the biochemical pool, and the nozzles 4 on the branch 8 in the middle of the biochemical pool body 1 are cleaned. The cleaned scum flows out from the overflow port 6 under the surging of the water flow, and is filtered at the lower level for impurity collection, which completely changes the current mode of manually scrubbing the pool wall and manually clearing the scum on the pool surface, reduces the labor cost of the enterprise and the safety risk of personnel operation, and quickly and continuously handles the scum and aged sludge on the pool surface.

[0020] More specifically, Figure 2 As shown, a groove 11 with an inverted trapezoidal cross section is provided on the floor of the biochemical pool body 1, and the hydraulic cylinder 9 and the telescopic rod 10 are both hinged in the groove 11. The lifting device is arranged in the groove 11, which facilitates strong flushing of the bottom of the pool wall and the floor of the biochemical pool body 1, thereby improving the cleaning effect.

[0021] In another embodiment, Figure 1 and Figure 2As shown, the nozzles 4 on the water spray pipeline 3 are arranged in two rows in parallel, and the nozzles 4 are arranged obliquely toward the pool wall of the biochemical pool body 1, and the nozzles 4 on the branch 8 are arranged in two rows in parallel, and the nozzles 4 are arranged obliquely toward both sides of the branch 8. The inclined nozzles 4 increase the flushing range of the nozzles 4 and reduce the cost investment.

[0022] In another embodiment, Figure 2 As shown, the water spray pipe 3 is fixedly connected with a connector 12 corresponding to the biochemical pool body 1, and the connector 12 is fixedly connected with bristles 13, and the bristles 13 abut against the pool wall of the biochemical pool body 1. Through the arrangement of the bristles 13, the water spray pipe 3 drives the bristles 13 to clean the pool wall of the biochemical pool body 1 during the lifting process, thereby improving the cleaning effect of the pool wall.

[0023] In another embodiment, Figure 2 As shown, rollers 14 are evenly fixedly mounted on the connecting member 12, and the rollers 14 abut against the pool wall of the biochemical pool body 1. This facilitates the stable lifting and lowering of the water spraying pipeline 3 and improves the stability of the system operation.
