An overflow port 3 is provided on one side wall of the outlet end of the wastewater treatment tank 1. The lower middle part of the wastewater treatment tank 1 is funnel-shaped. A sewage pipe 4 is provided at the bottom of the wastewater treatment tank 1. A sludge removal component is provided on the sewage pipe 4 to prevent excessive sludge from accumulating in the wastewater treatment tank 1. The sludge removal component includes a rotating shaft 5 installed on the partition frame 2. A spiral blade 6 is provided in the lower middle part of the rotating shaft 5. The spiral blade 6 is located inside the sewage pipe 4.

[0021] Wastewater treatment tank 1 is a commonly used treatment tank for treating wastewater generated in environmental engineering projects. The partition frame 2 is n-shaped and is fixedly installed in the middle of the partition frame 2. The partition frame 2 can separate the wastewater treatment tank 1. The overflow port 3 is opened on one side of the wastewater treatment tank 1. The treated wastewater is discharged from the overflow port 3. The bucket-shaped part facilitates wastewater treatment. The sewage pipe 4 is integrally formed with the wastewater treatment tank 1. The bottom end of the sewage pipe 4 is sealed by a cover. The sludge generated after treatment can be discharged from the sewage pipe 4. The rotating shaft 5 is rotatably connected to the partition frame 2. The spiral blade 6 is fixed to the lower middle part of the rotating shaft 5. The rotating shaft 5 uses a geared motor as power, which can drive the spiral blade 6 to rotate, which can facilitate the discharge of sludge. More specifically, the middle part of the partition frame 2 is provided with a dispensing port 14 for adding wastewater treatment agents, which can add the corresponding agents into the wastewater treatment tank 1 and improve the wastewater treatment effect.

[0022] In one embodiment, specifically, a mounting frame 7 is provided inside the sewage treatment tank 1 and on one side of the partition frame 2. The mounting frame 7 is inclined and has a filter box 8 for treating sewage. The mounting frame 7 is also provided with multiple positioning components for fixing the filter box 8. The positioning components include positioning columns 9 mounted on the mounting frame 7, and rotating plates 10 are provided on the positioning columns 9. The mounting frame 7 is inclined between the partition frame 2 and the sewage treatment tank 1. The filter box 8 is mounted on the mounting frame 7 and consists of multiple filter screens. The mounting frame 7 and the filter box 8 can separate the sewage treatment tank 1. Sewage is filtered through the filter box 8 and discharged from the overflow port 3. The positioning columns 9 are fixed to the mounting frame 7, and the rotating plates 10 are rotatably connected to the positioning columns 9. The rotation of the rotating plates 10 facilitates the assembly and disassembly of the filter box 8.

[0025] In operation, wastewater is pumped from one end of the coarse filter plate 13 into the wastewater treatment tank 1. Large impurities in the wastewater are filtered by the coarse filter plate 13. After filtration, the wastewater enters the middle of the wastewater treatment tank 1, where chemicals are added for treatment. As the water level in the wastewater treatment tank 1 rises, the wastewater passes through the filter box 8 for further filtration. The filtered water is discharged from the overflow port 3. When the sludge accumulates to a certain height in the wastewater treatment tank 1, the water supply to the wastewater treatment tank 1 is stopped, and the tank is allowed to stand for a certain period of time. Afterwards, discharge the high-concentration sewage from sewage treatment tank 1. At this time, open the cover at the bottom of the drain pipe 4. When the sewage treatment tank 1 is blocked, rotate the shaft 5. The shaft 5 can drive the spiral blades 6 on it to rotate, which can clear the discharged sludge. When the filter box 8 is blocked, use the backwash pipe 11 to flush the filter box 8. When there are too many impurities on the coarse filter plate 13, remove the coarse filter plate 13 for cleaning. After the high-concentration sewage and sludge are discharged, close the drain pipe 4 again with the cover.
