Compared with the urban sewage treatment plant, the rural sewage treatment facility is small in scale and high in unit operation and maintenance cost.

[0003] In the related art, the rural sewage treatment adopts the improved Bardenpho process for sewage treatment, and the treatment process is: after the domestic sewage is pretreated by the grid and the adjusting tank, the domestic sewage is treated by the "anaerobic - anoxic - aerobic - anoxic - aerobic" five-stage treatment process, and after the sludge water separation of the secondary sedimentation tank and the final sedimentation tank, the supernatant is discharged.

[0004] However, in the related art, two secondary sedimentation tanks are provided with three sludge pumps (2 use 1 spare), and two final sedimentation tanks are also provided with three sludge pumps (2 use 1 spare). In the actual operation process, four sedimentation tanks (two secondary sedimentation tanks and two final sedimentation tanks) are provided with six sludge pumps, which causes resource waste, is not conducive to the saving of investment and operation and maintenance costs, and makes the required space between the equipment larger, which is not conducive to land saving.

[0005] Therefore, it is necessary to optimize and improve the existing rural sewage treatment equipment, and provide an efficient and economical rural sewage treatment equipment. UTILITY MODEL CONTENTS

[0010] Three sludge pumps are arranged in parallel between the first pipeline and the second pipeline through three fourth pipelines, and the sludge water from the third pipelines is transported to the sludge tank through the first pipeline.

[0011] According to one embodiment of the rural sewage treatment equipment of the utility model, two hoppers arranged in parallel are respectively arranged in the four sedimentation tanks.

[0012] According to one embodiment of the rural sewage treatment equipment, the mud bucket is arranged at the bottom of the sedimentation tank, each mud bucket is provided with a bottom wall and a side wall, and the included angle of the side wall relative to the bottom wall is 60 degrees.

[0013] According to one embodiment of the rural sewage treatment equipment, a check valve is arranged on the fourth pipeline.

[0014] According to one embodiment of the rural sewage treatment equipment, the check valve is arranged on the fourth pipeline between the sludge pump and the first pipeline.

[0015] According to one embodiment of the rural sewage treatment equipment, butterfly valves are arranged on the second pipeline, the third pipeline and the fourth pipeline respectively.

[0016] Compared with the prior art, the rural sewage treatment equipment has the following technical effects:

[0017] Firstly, without changing the positions of the original sedimentation tank and sludge tank, by adjusting the pipeline and valve arrangement, three sludge pumps are shared by four sedimentation tanks (one standby for two), which effectively reduces the number of sludge pumps and can reduce 12%-15% of the equipment investment.

[0018] Secondly, by reducing the equipment and reasonably arranging the equipment, the layout between the equipment is optimized, and the land use can be reduced by 20%-25%.

[0019] Finally, due to the reduction of equipment investment, the operation and maintenance cost is also reduced by 3%-5%. BRIEF DESCRIPTION OF DRAWINGS
