DETAILED DESCRIPTION

[0024] Reference Figure 1-Figure 6 A sewage treatment sedimentation tank for environmental engineering includes a sedimentation tank body 1, in which a retaining wall 16 and a retaining wall 213 are arranged, and the retaining wall 16 and the retaining wall 213 divide the sedimentation tank body 1 into a sedimentation tank 1 25, a sedimentation tank 2 26 and a sedimentation tank 3 27. The retaining wall 16 and the retaining wall 213 are used to block sewage and prevent sewage from entering and flowing out of the sedimentation tank 2 26. A filter net 13 is arranged above the sedimentation tank 1 25, and the filter net 13 is a large-aperture filter net, so that the sewage that has not entered the sedimentation tank 1 25 can first filter out larger debris.

[0025] An inclined plate 2 is provided below the sedimentation tank 25 to allow the mud in the sewage to settle and fall to the middle of the inclined plate 2. An inclined plate 8 is provided below the sedimentation tank 26 to allow the mud in the sewage to settle and fall to the middle of the inclined plate 8. A filter screen 47 is provided above the inclined plate 28. The filter screen 47 is a small-aperture filter screen for filtering smaller debris and scum remaining in the sewage. A filter screen 24 and a filter screen 35 are provided on both sides of the retaining wall 6 respectively. The filter screen 24 and the filter screen 35 are medium-aperture filter screens for filtering the debris in the sewage again.

[0026] A sponge 12 is provided in the retaining wall 13 to absorb smaller debris and scum remaining in the sewage. A water absorption device is provided in the sedimentation tank 27 to discharge the sewage filtered in the sedimentation tank 27. Both the sedimentation tank 1 25 and the sedimentation tank 2 26 are provided with mud discharge devices to discharge the mud settled in the sedimentation tank 1 25 and the sedimentation tank 2 26.

[0027] The water suction device includes a water suction machine 16 , and the two sides of the water suction machine 16 are respectively connected to the water suction pipe 15 and the water outlet pipe 17 . The water suction machine 16 provides kinetic energy so that the water suction pipe 15 absorbs water through the water suction machine 16 and discharges it through the water outlet pipe 17 .

[0028] The mud discharge device includes a mud pipe three 23, and the mud pipe three 23 connects the mud pipe one 21 and the mud pipe two 22. The mud passing through the mud pipe one 21 and the mud pipe two 22 all flows into the mud pipe three 23. The other end of the mud pipe one 21 is connected to the sedimentation tank one 25, so that the mud settled in the sedimentation tank one 25 flows into the mud pipe one 21. A water valve one 18 is installed on the mud pipe one 21, and the water valve one 18 controls the mud to enter and exit the mud pipe one 21. The other end of the mud pipe two 22 is connected to the sedimentation tank two 26, so that the mud settled in the sedimentation tank two 26 flows into the mud pipe two 22. A water valve two 19 is installed on the mud pipe two 22, and the water valve two 19 controls the mud to enter and exit the mud pipe two 22.

[0029] Sedimentation tank 1 25 is located in the sedimentation tank body 1, and one side of sedimentation tank 1 25 is sedimentation tank 2 26. Sewage passes through sedimentation tank 1 25 and flows into sedimentation tank 2 26 after being filtered. Sedimentation tank 1 25 and sedimentation tank 2 26 are separated by retaining wall 1 6 to prevent sewage from directly flowing from sedimentation tank 1 25 into sedimentation tank 2 26. Retaining wall 1 6 is provided with a first small hole. Filter net 2 (4) and filter net 3 (5) are both fixed in the first small hole. Filter net 2 4 and filter net 3 5 filter the impurities in the sewage again. Sedimentation tank 2 26 is located on the other side of sedimentation tank 3 27. Sewage flows from sedimentation tank 2 26 to sedimentation tank 3 27. Sedimentation tank 2 26 and sedimentation tank 3 27 is separated by a retaining wall 13 to prevent sewage from flowing directly from the sedimentation tank 26 to the sedimentation tank 3 27. A second small hole is provided in the retaining wall 13, and the second small hole is filled with a sponge 12. The sponge absorbs small debris in the sewage. A horizontally placed squeezing block 24 is provided in the middle of the sponge 12, and the two sides of the squeezing block 24 are respectively connected to the telescopic rod 14 and the telescopic rod 20, so that the squeezing block 24 connected to the telescopic rod 14 and the telescopic rod 20 moves up and down to squeeze the sponge, and the other ends of the telescopic rod 14 and the telescopic rod 20 are respectively connected to the upper and lower sides of the second small hole, and the other ends of the telescopic rod 14 and the telescopic rod 20 are fixed to the upper and lower sides of the second small hole.

[0030] A filter screen 47 is provided in the sedimentation tank 26 to clean some debris and scum remaining in the sewage. The filter screen 47 is connected to the strip plate 11, and the strip plate 11 is connected to the remote control slider 10. The remote control slider 10 moves, driving the filter screen 47 connected to the strip plate 11 to move up and down. A slider groove 9 is opened in the sedimentation tank 26, and the remote control slider 10 is located in the slider groove 9, so that the remote control slider 10 moves up and down in the slider groove 9.

[0031] The working principle of the utility model is as follows: the sewage first enters the sedimentation tank 25, and the larger debris is filtered out by the filter net 3, and then the larger mud in the sewage settles to the inclined plate 2. Due to the influence of gravity, the mud is concentrated in the middle of the inclined plate 2, and the sewage is intercepted by the retaining wall 6 to prevent the sewage from entering the sedimentation tank 26. When the amount of sewage continues to increase and reaches the filter net 4, it is first filtered by the filter net 4, and then filtered by the filter net 3 5, and then enters the sedimentation tank 26. After the sewage sedimentation tank 26, the mud settles again in the middle of the inclined plate 28. Some debris and scum remaining in the sewage will be filtered again by the remote control slider 10 connected to the filter net 4 7. The sewage rises to the sponge 1 2, the sponge 12 will filter out finer impurities in the sewage, and the sewage will be filtered again through the sponge 12. A squeezing block 24 is provided in the middle of the sponge 12, and the two sides of the squeezing block 24 are respectively connected to the telescopic rod 14 and the telescopic rod 20. When the sewage is filtered through the sponge 12, the sponge 12 will be blocked. The squeezing block 24 connected to the telescopic rod 14 and the telescopic rod 20 can be moved up and down to squeeze out the impurities in the sponge 12, and the impurities will fall into the sedimentation tank 26. The filtered sewage will enter the sedimentation tank 3 27, and then be sucked out by the suction machine 16 connected to the suction pipe 15. The mud settled between the inclined plate 1 2 and the inclined plate 2 8 will be discharged through the mud pipe 1 21 and the mud pipe 2 22 through the mud pipe 3 23.
