Description

Technical Field

[0001] The utility model belongs to the technical field of oxidation ditches, and particularly relates to an improved oxidation ditch for sewage treatment. Background Technique

[0002] In the sewage treatment process, the oxidation ditch is a commonly used biological treatment device, which removes organic matter and other pollutants in sewage through the action of microorganisms. However, during the operation of the oxidation ditch, the phenomenon of floating sludge often occurs, that is, suspended solids and some microorganisms in the sewage gather on the surface of the oxidation ditch to form a floating sludge layer. These floating sludges not only affect the treatment effect of the oxidation ditch, but also may have an adverse impact on the subsequent treatment process. Traditional floating sludge treatment methods mostly rely on manual cleaning or natural sedimentation. These methods are not only inefficient but also costly, and it is difficult to meet the operation requirements of modern sewage treatment plants.

[0003] Therefore, it is very necessary to invent an improved oxidation ditch for sewage treatment. Content of the Utility Model

[0005] The floating sludge collection mechanism includes a floating sludge collection cover, a floating sludge baffle, a floating sludge screw, a waterproof motor, a floating sludge valve and a floating sludge collection box. The floating sludge collection cover is fixedly installed on the oxidation ditch, and the floating sludge baffle is fixedly connected to the floating sludge collection cover and the oxidation ditch; the floating sludge screw is arranged on one side of the floating sludge baffle, one end of the floating sludge screw is rotatably installed in the floating sludge collection cover, the other end of the floating sludge screw rotatably passes through the oxidation ditch and is fixed to the output end of the waterproof motor fixedly installed on the oxidation ditch; one end of the floating sludge collection cover penetrates into the floating sludge collection box and is installed and connected with the floating sludge valve; the floating sludge collection box is fixedly installed on the base.

[0006] Preferably, a notch is opened on the oxidation ditch, one end of the floating sludge collection cover is fixedly installed at the notch position, and the floating sludge collection cover is of a rectangular horn cover structure.

[0007] Preferably, the floating sludge collection cover is used to connect the oxidation ditch and the floating sludge collection box, and the water surface inside the oxidation ditch is higher than the installation height where the floating sludge collection box is located.

[0008] Preferably, the floating sludge baffle and the floating sludge screw rod are located inside the oxidation ditch. The floating sludge screw rod is located at the water surface position of the oxidation ditch and is used to push the floating sludge on the water surface into the floating sludge collection hood.

[0009] Preferably, the floating sludge baffle and the floating sludge screw rod are horizontally distributed on one side of the end of the floating sludge collection hood. The floating sludge baffle is of a rectangular structure and extends into the water surface of the oxidation ditch.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model cleverly combines the principles of physical blockage and mechanical propulsion to achieve effective collection of floating sludge. The floating sludge collection hood adopts a rectangular horn-shaped structure, which can guide the floating sludge into the collection channel. The floating sludge baffle extends deep into the water surface to prevent the floating sludge from escaping during the collection process, thereby improving the collection efficiency.

[0018] As shown in the attached Figure 1 to the attached Figure 2 figures:

[0019] An improved oxidation ditch for sewage treatment provided by the present utility model includes an oxidation ditch 1, a base 2, a floating sludge collection mechanism 3, an aeration tank bottom 4, and an aeration pipe 5. The base 2 is arranged on one side of the oxidation ditch 1, and the floating sludge collection mechanism 3 is installed on the oxidation ditch 1 and the base 2; the aeration tank bottom 4 is fixedly installed at the bottom of the oxidation ditch 1, and the aeration tank bottom 4 is communicated with the aeration pipe 5 fixedly installed on one side of the oxidation ditch 1.

[0020] The floating sludge collection mechanism 3 includes a floating sludge collection cover 31, a floating sludge baffle 32, a floating sludge screw 33, a waterproof motor 34, a floating sludge valve 35, and a floating sludge collection box 36. The floating sludge collection cover 31 is fixedly installed on the oxidation ditch 1, and the floating sludge baffle 32 is fixedly connected to the floating sludge collection cover 31 and the oxidation ditch 1; the floating sludge screw 33 is arranged on one side of the floating sludge baffle 32. One end of the floating sludge screw 33 is rotatably installed in the floating sludge collection cover 31, and the other end of the floating sludge screw 33 rotatably passes through the oxidation ditch 1 and is fixed to the output end of the waterproof motor 34 fixedly installed on the oxidation ditch 1; one end of the floating sludge collection cover 31 penetrates into the floating sludge collection box 36 and is installed and connected to the floating sludge valve 35; the floating sludge collection box 36 is fixedly installed on the base 2.

[0021] Embodiment 1:

[0022] Specifically, a notch is formed on the side wall of the oxidation ditch 1. The position and size of this notch need to be precisely designed according to the size of the floating sludge collection hood 31. One end of the floating sludge collection hood 31 is fixedly installed at this notch position to ensure that the hood body is stable and tightly connected to the oxidation ditch 1, preventing water leakage or loosening during the process of collecting floating sludge. The floating sludge collection hood 31 adopts a rectangular horn-shaped hood structure, which is beneficial to guiding the floating sludge to smoothly enter the collection channel and reducing the interference of water flow on the collection process.

[0023] Specifically, the other end of the floating sludge collection hood 31 extends to the outside and is connected to the floating sludge collection tank 36. In order to ensure that the collected floating sludge can smoothly drain into the floating sludge collection tank 36, a floating sludge valve 35 is installed between the floating sludge collection hood 31 and the floating sludge collection tank 36. In addition, in order to prevent sewage backflow or external impurities from entering the oxidation ditch, the floating sludge valve 35 has good sealing performance. At the same time, since the water surface inside the oxidation ditch 1 is higher than the installation height of the floating sludge collection tank 36, the floating sludge can naturally flow into the floating sludge collection tank 36 under the action of gravity and the floating sludge screw rod 33.

[0024] Specifically, the floating sludge baffle 32 and the floating sludge screw rod 33 are both located inside the oxidation ditch 1 and are horizontally distributed on one side of the end of the floating sludge collection hood 31. The floating sludge baffle 32 is of a rectangular structure and extends into the water surface of the oxidation ditch 1 to play a role in blocking the escape of floating sludge. When the floating sludge is carried by the water flow to near the floating sludge baffle 32, it will be intercepted by the floating sludge baffle 32 and accumulate in front of the floating sludge baffle 32. At this time, the floating sludge screw rod 33 starts to play a role. The floating sludge screw rod 33 is located at the water surface position. One end of it is rotationally installed in the floating sludge collection hood 31 through components such as bearings, and the other end is connected to the waterproof motor 34 installed outside the oxidation ditch 1. After the waterproof motor 34 is started, it drives the floating sludge screw rod 33 to rotate, thereby continuously pushing the floating sludge accumulated in front of the floating sludge baffle 32 into the floating sludge collection hood 31. With the continuous rotation of the floating sludge screw rod 33 and the continuous accumulation of floating sludge, the floating sludge will finally enter the floating sludge collection tank 36 through the floating sludge collection hood 31.

[0025] Embodiment Two:

[0026] The floating sludge floats with the water flow in the oxidation ditch 1. When it is brought near the floating sludge baffle 32, since the floating sludge baffle 32 extends deep into the water surface, it plays a role in blocking the escape of the floating sludge. As a result, the floating sludge is intercepted and accumulates on the front side of the floating sludge baffle 32. At the same time, the waterproof motor 34 starts, driving the floating sludge screw 33 to rotate. The rotating floating sludge screw 33 continuously pushes the floating sludge accumulated in front of the floating sludge baffle 32 into the floating sludge collection hood 31. The floating sludge pushed into the floating sludge collection hood 31 enters the floating sludge collection box 36 through the other end of the floating sludge collection hood 31 under the action of gravity and the continuous push of the floating sludge screw 33. In order to ensure the smooth discharge of the floating sludge, a floating sludge valve 35 is installed between the floating sludge collection hood 31 and the floating sludge collection box 36. This valve has good sealing performance to prevent the backflow of sewage or the entry of external impurities. Since the water surface inside the oxidation ditch 1 is higher than the installation height of the floating sludge collection box 36, the floating sludge naturally flows into the floating sludge collection box 36 under the dual action of gravity and the floating sludge screw 33. With the continuous rotation of the screw and the continuous accumulation of the floating sludge, the amount of floating sludge in the floating sludge collection box 36 gradually increases. After reaching a certain amount, the floating sludge collection box 36 can be cleaned regularly.

[0027] Using the technical solution of the present utility model, or a person skilled in the art being inspired by the technical solution of the present utility model to design a similar technical solution and achieving the above technical effects shall fall within the protection scope of the present utility model.
