[0002] Sewage treatment refers to the process of treating sewage from domestic, industrial, agricultural and other fields by physical, chemical, biological and other means to remove or reduce pollutants so that it meets the discharge standards or reuse requirements. The main goals of sewage treatment are to protect the environment, prevent water pollution, protect public health and achieve sustainable use of water resources. The sewage treatment tank is an important part of the sewage treatment system, which is used to collect, store, treat and purify sewage from domestic, industrial or other sources to reduce its pollution to the environment and make the treated water meet the discharge standards or reuse requirements. The design, construction and operation of the sewage treatment tank will vary according to factors such as treatment process, water quality characteristics, treatment scale and local regulatory requirements. In the process of sewage treatment in the sewage treatment tank, sewage scum refers to solid or semi-solid substances floating on the water surface or suspended in the water body separated from sewage by physical or chemical methods during the sewage treatment process. These scums are mainly composed of organic matter, inorganic matter, microorganisms, plankton, oil, foam and so on in sewage. The traditional method of collecting scum is for workers to use handheld sieves to salvage the scum on the water surface in the sewage pool.

DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the specific implementation manner of the utility model will be clearly and completely described below.

[0018] The utility model discloses a sewage treatment pool 100, such as Figure 1 As shown, the sewage treatment tank 100 includes a treatment tank 11, a sliding track 12, a cleaning assembly 13 and a driving assembly 14. The front end of the treatment tank 11 is connected to a water inlet pipe 111 near the upper part, and the rear end of the treatment tank 11 is connected to a water outlet pipe 112 near the lower part. The sewage flows into the treatment tank 11 from the water inlet pipe 111 at the front end of the treatment tank 11. After sedimentation and impurities removal, the sewage flows out of the treatment tank 11 from the water outlet pipe 112 at the rear end of the treatment tank 11. The sliding track 12 includes at least four, and at least two sliding tracks 12 are respectively provided on the left end and the right end of the treatment tank 11. Figure 2As shown, the cleaning component 13 includes a scum collecting member 131, an upper fixed rod 132 and a lower fixed rod 133. One side of the scum collecting member 131 is open, and a plurality of through holes are provided on the side of the scum collecting member 131 away from the opening. The upper fixed rod 132 is fixedly connected to the upper part of the side of the scum collecting member 131 away from the opening, and the lower fixed rod 133 is fixedly connected to the lower part of the side of the scum collecting member 131 away from the opening. Both ends of the upper fixed rod 132 are respectively connected to the sliding rails 12 on the left and right ends of the processing pool 11 close to the upper part of the processing pool 11, and both ends of the lower fixed rod 133 are respectively connected to the sliding rails 12 on the left and right ends of the processing pool 11 close to the lower part of the processing pool 11. The driving component 14 is arranged on one side outside the processing pool 11, and the driving component 14 is electrically connected to the cleaning component 13. The cleaning component 13 provided in the present application salvages and removes the sewage scum on the upper layer of the sewage by moving on the sliding track 12. When the sewage treatment tank 100 of the present application is in use, the sewage is first introduced into the treatment tank 11 and then left to stand. After standing for a period of time, sewage scum will appear in the upper layer of the sewage in the treatment tank 11. At this time, the staff can turn on the driving component 14 and operate the driving component 14. The driving component 14 drives the scum collecting part 131 on the cleaning component 13. The scum collecting part 131 moves on the sliding track 12 through the upper fixing rod 132 and the lower fixing rod 133, and moves from the front end of the treatment tank 11 to the front end of the treatment tank 11. At the rear end of the treatment tank 100, during the process of the scum collecting member 131 moving from the front end to the rear end of the treatment tank 11, the opening on one side of the scum collecting member 131 collects the sewage scum of the treatment tank 11 into the scum collecting member 131, and finally the scum collecting member 131 that has collected the sewage scum on the upper layer of the treatment tank 11 stays at the rear end of the treatment tank 11. At this time, the staff only needs to clean the sewage scum in the scum collecting member 131. The cleaning component 13 greatly improves the staff's cleaning efficiency of the sewage treatment tank 100, and compared with manual cleaning, the cleaning component 13 cleans the sewage scum on the upper layer of the treatment tank 11 more cleanly. The present application is provided with a plurality of through holes on the side of the scum collecting member 131 away from the opening. The through holes are for the purpose of allowing the sewage to pass through the scum collecting member 131 when it moves on the upper layer of the treatment tank 11, thereby reducing the resistance generated by the sewage.

[0019] As an implementation mode, the distance between the upper sliding rails 12 on the same side of the treatment tank 11 is consistent, and the end of the sliding rail 12 close to the rear end of the treatment tank 11 is bent upward. The cleaning component 13 moves on the sliding rail 12 through the upper fixing rod 132 and the lower fixing rod 133. In order to ensure the horizontal movement of the scum collecting part 131 on the cleaning component 13, the distance between the upper sliding rails 12 on the same side of the treatment tank 11 is consistent. The scum collecting part 131 stays at the rear end of the treatment tank 11 after cleaning in the treatment tank 11. At this time, the staff needs to salvage and clean the sewage scum in the scum collecting part 131, but the scum collecting part 131 is still in the sewage at this time, and because the opening on one side of the scum collecting part 131 is generally in the direction from the front end of the treatment tank 11 toward the rear end of the treatment tank 11, it will cause harm to the workers. The salvage of the scum collecting member 131 will be affected to a certain extent. In the present application, the sliding track 12 is bent upward at one end close to the rear end of the treatment tank 11. When the scum collecting member 131 moves to the rear end of the treatment tank 11 on the sliding track 12, the position and direction of the scum collecting member 131 will change through the sliding track 12. On the one hand, the scum collecting member 131 will be moved out of the sewage in the treatment tank 11 along the sliding track 12 until it is above the treatment tank 11. On the other hand, one end of the scum collecting member 131 is opened toward the top of the treatment tank 11. The above-mentioned arrangement makes it easy for the staff to salvage and clean the sewage scum in the scum collecting member 131, thereby improving the salvage and cleaning efficiency of the staff.

[0020] As an embodiment, a flow guide 1311 is provided on one side of the opening of the scum collecting member 131, and both sides of the flow guide 1311 are arranged to be inclined upward. When the scum collecting member 131 moves in the treatment tank 11, the sewage scum is collected through the opening on one side of the scum collecting member 131. However, when the scum collecting member 131 moves in the sewage in the treatment tank 11, it will drive the sewage to move. At this time, a small part of the sewage scum in the sewage will move with the sewage to outside the salvage range of the opening on one side of the scum collecting member 131, so that some sewage scum cannot be collected by the scum collecting member 131. In this application, by providing the flow guide 131 on one side of the opening of the scum collecting member 131, the sewage scum can be collected. 1. The sewage outside the salvage range of the opening of the scum collecting member 131 is introduced into the scum collecting member 131 through the guide member 1311, so that the sewage scum in the sewage is introduced into the scum collecting member 131, which increases the salvage area of ​​the opening of the scum collecting member 131 in disguised form. The two sides of the guide member 1311 of the present application are inclined upward, and the inclined setting can also drain the sewage, further increase the salvage area of ​​the opening of the scum collecting member 131, so that the scum collecting member 131 can salvage more sewage scum.

[0021] As an implementation method, Figure 2As shown, the upper fixed rod 132 is arranged parallel to the lower fixed rod 133, the direction from the upper fixed rod 132 to the lower fixed rod 133 is the extension direction of the fixed rod, the direction from the front end of the treatment pool 11 to the rear end of the treatment pool 11 is the horizontal direction, and the angle α between the extension direction of the fixed rod and the horizontal direction is greater than or equal to 20° and less than or equal to 80°. The present application introduces sewage and sewage scum in the sewage into the scum collecting member 131 through an opening on one side of the scum collecting member 131. When the angle α between the extension direction of the fixed rod and the horizontal direction is less than 20°, the inclination angle of the scum collecting member 131 and the opening on one side of the scum collecting member 131 is large, so that the opening area on one side of the scum collecting member 131 along the sliding track 12 is small, and less sewage and sewage scum introduced can be collected. When the angle α between the extension direction of the fixed rod and the horizontal direction is greater than 80°, the angle between the scum collecting member 131 and the sliding track 12 is small, and the scum collected in the scum collecting member 131 may flow out from the opening on one side of the scum collecting member 131, affecting the effect of the scum collecting member 131 in collecting scum. In summary, the present application sets the angle α between the extension direction of the fixed rod and the horizontal direction to be greater than or equal to 20° and less than or equal to 80°. Further, the angle α between the extension direction of the fixing rod and the horizontal direction is greater than or equal to 30° and less than or equal to 70°. Further, the angle α between the extension direction of the fixing rod and the horizontal direction is greater than or equal to 40° and less than or equal to 60°.

[0022] As an implementation method, Figure 3 As shown, the length of the diameter d of the through hole on the scum collecting member 131 is less than or equal to 0.2 mm and greater than or equal to 0.05 mm. Further, the length of the diameter d of the through hole on the scum collecting member 131 is less than or equal to 0.18 mm and greater than or equal to 0.07 mm. Further, the length of the diameter d of the through hole on the scum collecting member is less than or equal to 0.16 mm and greater than or equal to 0.09 mm.

[0023] As an embodiment, the cleaning component 13 includes an adsorbent 134, which is detachably connected to both sides of the scum collecting member, and has a plurality of adsorption through holes. There are also some debris in the sewage that is finer than the sewage scum, which is difficult to be completely cleaned only through the through holes on one side of the scum collecting member. The present application provides the adsorbent 134 to adsorb smaller debris, which can improve the filtering effect of the scum collecting member.

[0024] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
