[0032] When the driving assembly is in use, the driving motor 10 controls the driving pulley 11 to rotate. Under the transmission effect of the transmission belt 13, the driven pulley 12 drives the rotating tube 3 to rotate, and then the rotating tube 3 drives the nozzle 5 installed at the bottom of the spraying frame 4 to rotate to expand the spraying range, so that the sewage treatment agent can be sprayed more evenly into the sewage treatment tank 1;

[0033] A stirring assembly, comprising a stirring shaft 15 fixedly connected to the outer wall of the bottom of the spray frame 4 and a double helical stirring blade 16 welded to the outer wall of the stirring shaft 15, wherein the stirring shaft 15 is coaxially arranged with the rotating tube 3;
