[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-5 As shown, the PE combined sewage treatment tank includes two tank bodies 1, and a plurality of bolts 2 are threadedly installed on the outer surfaces of the two tank bodies 1 near the connection positions on both sides. A water filling bucket 3 is fixedly installed on the top of one of the tank bodies 1 near the front center position, and a plurality of filter holes 4 are opened at the bottom of the water filling bucket 3. A filter plate 5 is slidably installed on the top of the filter holes 4 inside the water filling bucket 3, and a cleaning stirring structure 6 is arranged inside the water filling bucket 3. The cleaning stirring structure 6 includes a connecting rod 7 and a stirring rod 8, and a pull cap 9 is fixedly installed on the top of the connecting rod 7.

[0022] In this embodiment, in order to fix the water filling bucket 3 more firmly, the bottom of the water filling bucket 3 passes through the top of one of the tank bodies 1, and a semicircular groove is opened on the top of the other tank body 1, and the size of the semicircular groove matches the water filling bucket 3.

[0023] In this embodiment, in order to enable the connecting rod 7 to pull the filter plate 5, the bottom of the connecting rod 7 passes through the bottom of the filter plate 5 and the bottom of the water filling bucket 3, and the bottom of the connecting rod 7 is located just above the bottom position inside the tank body 1.

[0024] In addition, the stirring rod 8 is fixedly installed on the outer surface of the connecting rod 7 near the bottom position, the limiting ring 10 is fixedly installed on the top of the water filling bucket 3, and two fixed rods 11 are fixedly installed on the outer surface of the connecting rod 7 at the top position of the filter plate 5. A movable rod 12 is slidably installed inside the two fixed rods 11 near one end, and a spring 13 is fixedly installed inside the fixed rod 11 near the other end, and one end of the spring 13 is fixedly connected to the other end of the movable rod 12.

[0025] In this embodiment, in order to clean the inner wall of the water filling bucket 3 while pulling the filter plate 5 upward, a scraper is fixedly installed on the outer surface of the filter plate 5. The outer circle radius of the scraper is consistent with the inner circle radius of the water filling bucket 3, and the inner circle radius of the limit ring 10 is smaller than the inner circle radius of the water filling bucket 3.

[0026] In this embodiment, in order to accelerate the reaction rate of the medicine, the stirring rod 8 is composed of a plurality of round rods, the length of which is smaller than the radius of the internal space of the tank body 1, and a drain valve is installed through the outer surface of one of the tank bodies 1 near the bottom.

[0027] It should be noted that the utility model is a PE combined sewage treatment tank. When in use, the two tank bodies 1 are combined into a treatment tank by bolts 2, and the sewage to be treated is then injected into the water injection barrel 3 and flows into the combined tank. When the sewage flows into the combined tank through the filter hole 4, the filter hole 4 and the filter plate 5 filter the sewage. When the sewage is injected, the connecting rod 7, the filter plate 5 and the stirring rod 8 are driven to move upward at the same time by pulling the pull cap 9. When the filter plate 5 moves to the bottom of the limit ring 10, the fixed rod 11 is located above the limit ring 10 at this time, and the spring 13 rebounds and drives the movable rod 12 to expand outward, so that the position of the filter plate 5 is fixed, and the pollutants accumulated on the filter plate 5 can be cleaned, and then the sewage treatment agent is injected into the combined tank from the water injection barrel 3. At this time, the stirring rod 8 is located at the center position inside the combined tank, and the connecting rod 7 starts to rotate to drive the stirring rod 8 to rotate, so that the agent and the sewage are fully reacted, and then the treated sewage is discharged through the drain valve.
