[0012] Preferably, the movable door leaf of the sewage gate is arranged at the bottom.

[0013] Preferably, the outlet of the sewage gate is provided with a conveying plate, which is arranged obliquely, and a sewage collecting box is connected to the lower side of the plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. In the utility model, after the sewage enters the separation well, the sediments such as mud and sand in the sewage sink to the bottom of the separation well. After the water level rises, the sewage passes through the filter plate, but the floating objects in the sewage cannot pass through the filter plate and remain in the separation well. The sewage passing through the filter plate is filtered and discharged through the sewage outlet, and the sediments and floating objects flow out through the sewage discharge gate. In addition, the solid-liquid separation of sewage can be completed without any external power, and the equipment is simple, energy-saving and environmentally friendly.

[0016] 2. In the utility model, sewage is filtered and flows out by overflowing the filter plate. The impact force and water pressure of the water flow are small, so the debris will not be squeezed on the filter plate by the water flow, so that the filter holes remain unobstructed. On the other hand, small or dense debris such as mud, sand and stones are usually deposited at the bottom of the well, which reduces the filtering burden of the filter plate and reduces the possibility of the filter holes being blocked.

[0024] A sewage solid-liquid separation device for municipal construction comprises a separation well 1, a sewage inlet 21 is provided on one side of the separation well 1 close to the top, a sewage inlet 21 is connected to a sewage inlet pipe 2, sewage is injected into the separation well 1 from the sewage inlet pipe 2 through the sewage inlet 21, a sewage outlet 31 is provided on the other side opposite to the sewage inlet 21, a sewage outlet 31 is connected to a sewage outlet 31, sewage in the separation well 1 rises to a certain height and flows out of the sewage outlet 3 through the sewage outlet 31, a filter sheet 12 is further provided in the separation well 1, the sewage inlet 21 is located below the filter sheet 12, and the sewage outlet 31 is located above the filter sheet 12, after the sewage is discharged into the separation well 1, the sediment in the sewage gradually sinks to the bottom of the separation well 1, and the floating objects in the sewage cannot pass through the filter sheet 12, so as the water level rises and passes through the filter sheet 12, the sediment and floating objects in the sewage are retained in the separation well 1, and the sewage passing through the filter sheet 12 is filtered and discharged through the sewage outlet 31.

[0025] The filter sheet 12 has a corrugated structure, which can greatly increase the contact area between the filter sheet 12 and the sewage and the filtering area, so that the sewage is filtered more smoothly and the filtering holes on the filter sheet 12 are not easily blocked.

[0026] A manhole cover 11 is provided on the top of the separation well 1. When cleaning and repairing the separation well 1, the staff can open the manhole cover 11 for operation; the four edges of the filter plate 12 are in contact with the wall of the separation well 1 to prevent debris in the sewage from drilling out from the gap between the filter plate 12 and the wall.

[0027] A fixing strip 5 is symmetrically arranged on the wall of the separation well 1, two opposite edges of the filter sheet 12 are respectively overlapped on the fixing strip 5, and contact arms 6 are symmetrically arranged on two sides of the filter sheet 12. There are no less than four contact arms 6. The bottom end of the contact arm 6 is fixedly connected to the filter sheet 12, and the top end of the contact arm 6 is provided with an abutment plate 61, which is perpendicular to the contact arm 6. When the separation well 1 closes the well cover 11 and operates normally, the upper part of the filter sheet 12 abuts against the well cover 11 through the abutment plate 61 and the contact arm 6. The lower part of the filter sheet 12 is abutted against the separation well 1 by the fixing strip 5, so that the filter sheet 12 is firmly fixed, and the filter sheet 12 can be directly taken out when the well cover 11 is opened, so that the filter sheet 12 or the separation well 1 can be cleaned, and loading and unloading are more convenient; the contact arm 6 is in contact with the well cover 11 through the abutment plate 61, and a through hole 62 is provided on the abutment plate 61. When taking out the filter sheet 12, the staff can use a tool such as a hook to pass through the through hole 62 to lift the filter sheet 12, and the operation is more convenient.

The inclination angle of the inclined bottom surface 7 is not less than 20°. The lower side of the inclined bottom surface 7 is located at the bottom end of the sewage gate 4. A movable door leaf 41 of the sewage gate 4 is arranged at the bottom. When the debris in the separation well 1 is about to be full, the sewage is stopped from being discharged and the movable door leaf 41 is opened, and the sediment and floating objects flow out through the sewage gate 4. The inclined bottom surface 7 can make the sediment slide down to the position of the sewage gate 4 under the action of gravity and be discharged.

[0029] A conveying plate 8 is provided at the outlet of the sewage gate 4. The conveying plate 8 is inclined. A sewage collecting box 9 is connected to the lower side of the conveying plate 8.
