Description

Technical Field

[0001] The present invention relates to the field of sewage treatment, and in particular to a composite pre-treatment device for sewage treatment. Background Art

[0002] Water pollution is a common problem faced worldwide. Constructed wetland technology is an important water pollution purification technology. Due to its good purification effect, low maintenance cost, and landscape effect, it is currently widely used in research and engineering such as polluted river water treatment, sewage treatment plant effluent treatment, and agricultural runoff treatment. If the water body contains a high concentration of suspended particles or large volumes of garbage, it is very easy to cause the wetland filler to be blocked, which in turn affects the uniform distribution of polluted water in the wetland system, resulting in a decrease in removal effect and shortening the service life of the constructed wetland. Therefore, it is crucial to prevent large volumes of garbage from entering the wetland and reduce the amount of suspended particles entering the wetland to extend the service life of the wetland and ensure the normal operation of the wetland. Large volumes of garbage can also easily block the pump and cause engineering accidents. Therefore, it is necessary to add a pre-treatment device before the sewage enters the wetland system.

[0003] The existing wetland pretreatment method is generally to add a crushed stone filter bed or an ecological gravel bed. This method requires regular replacement of fillers, has high maintenance costs, and it is difficult for the operating unit to detect filter bed blockage in time. Therefore, it is necessary to develop a new wetland pretreatment process. In response to this problem, the present invention designs a new pretreatment device for completely removing large volumes of garbage in the water body, significantly reducing suspended particulate matter, and at the same time reducing pollutants to a certain extent. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a composite pre-treatment device for sewage treatment to solve the problem that the existing composite pre-treatment device for sewage treatment still cannot effectively remove large-volume garbage in the water, reduce suspended particles in the water, and reduce the amount of pollutants.

[0005] A composite pre-treatment device for sewage treatment comprises a pool body, stairs, a water inlet, a water outlet, a salvaging mechanism and an intercepting mechanism, wherein: the stairs are arranged on one side of the pool body surface; the water inlet is arranged in the middle of one end of the pool body; the water outlet is arranged in the middle of the other end of the pool body surface; the salvaging mechanism and the intercepting mechanism are arranged between the pool body and the water inlet, and the intercepting mechanism is arranged on the rear side of the salvaging mechanism through a bracket.

[0006] Preferably, the interior of the pool body is provided with a first overflow area, a second overflow area, a water plant layer and a filter plate, and the first overflow area is arranged on one side of the water plant layer; the second overflow area is arranged on the other side of the water plant layer; the water plant layer is arranged in the middle of the inside of the pool body inlet; the filter plate is arranged in the middle of the inside of the pool body, and the filter plate is at the rear end of the water plant layer.

[0007] Preferably, the water inlet includes a manual debris placement area, a mechanical debris placement area and a workstation, and the manual debris placement area is arranged on one side of the water inlet surface; the mechanical debris placement area is arranged on the other side of the water inlet surface, and the mechanical debris placement area is directly below the top of the salvage mechanism; the workstation is arranged on one side of the top of the manual debris placement area, and the workstation is in the middle of the salvage mechanism and one end of the interception mechanism.

[0008] Preferably, the salvage mechanism includes a protective plate and a conveyor belt, and the protective plate is arranged on the outside of the conveyor belt; the conveyor belt is connected to the motor inside the salvage mechanism through a rotating shaft, and a baffle is arranged at a position symmetrical to the surface of the conveyor belt.

[0009] Preferably, the interception mechanism includes a bracket, a chassis, a screw and an interception plate, and the chassis is arranged at the top of the bracket; the screw is nested inside the bracket, and the top of the screw is connected to the motor inside the chassis; the interception plate is threadedly nested with the screw through a rotating sleeve.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. The setting of the salvage mechanism of the present invention is conducive to the salvage of garbage on the surface of the water body, so that it can be automatically salvaged and stored inside the mechanical salvage debris placement area. At the same time, through the setting of the salvage mechanism itself, it can avoid being entangled by soft garbage and affecting the work.

[0011] 2. The setting of the interception mechanism of the present invention is conducive to adjusting its overall height when in use, so that its height can be adjusted according to the water depth. At the same time, its height in the water can be adjusted according to the properties of the impurities to be intercepted, thereby effectively filtering impurities of different depths.

[0024] The salvage mechanism 5 includes a protective plate 51 and a conveyor belt 52, and the protective plate 51 is arranged on the outside of the conveyor belt 52; the conveyor belt 52 is connected to the motor inside the salvage mechanism 5 through a rotating shaft, and a baffle is arranged at a position symmetrical to the surface of the conveyor belt 52; the salvage mechanism 5 is arranged at an inclined angle of 30 to 45 degrees between the pool body 1 and the water inlet 3, and a leakage hole is opened on the surface of the conveyor belt 52; the interception mechanism 6 includes a bracket 61, a chassis 62, a screw rod 63 and an interception plate 64, and the chassis 62 is arranged at the top of the bracket 61; the screw rod 63 is nested in the inside of the bracket 61, and the top of the screw rod 63 is connected to the motor inside the chassis 62; the interception plate 64 is threadedly nested with the screw rod 63 through a rotating sleeve, and the surface of the interception plate 64 is provided with a filtering hole.
