[0038] The sewage treatment device for environmental engineering provided by the present invention has a working principle as follows: sewage is added to the box body 1 through the water inlet pipe 2, and the sewage injection is stopped when the sewage covers the stirring blade 23 located at the top, and flocculant powder is added through the hopper 3, and the flocculant powder is dropped into the spoon body 6 through the guide nozzle 4.

At this time, the flocculant powder in the spoon body 6 is scattered in the box body 1. At the same time, the spoon handle of the spoon body 6 triggers the travel switch 13, and the air pump 14 starts to run and blows air to the scattered flocculant powder through the blowing nozzle 11, so as to accelerate the diffusion of the flocculant powder and make it diffuse in every corner of the box body 1, so that the flocculant powder and the sewage are fully mixed. The scoop body 6 is in contact with the feed spoon, and the motor 19 is started to drive the stirring mechanism to stir, so as to further improve the uniform mixing of the flocculant powder and the sewage. When the flocculant in the feed spoon body 6 is scattered, the feed spoon bottom 7 is reset under the action of the reset shaft 9, and the two permanent magnets 8 are attracted to seal the bottom of the feed spoon body 6.

When the stirring is completed, the valve on the feed guide nozzle 4 (not shown in the figure) is closed to stop adding the flocculant. When the flocculation is completed, the valve 28 is opened to start discharging the treated water, and at the same time, the brush plate 35 is driven by the motor 19 to clean the floccules on the outer wall of the filter cartridge 30 to ensure smooth drainage.
