Description

Technical Field

[0001] This utility model relates to the technical field of oxidation tanks for domestic sewage treatment, and in particular to an oxidation tank for domestic sewage treatment. Background Technology

[0002] Wastewater treatment utilizes physical, chemical, and biological methods to purify wastewater, reduce pollution, and ultimately achieve wastewater recycling and reuse, fully utilizing water resources. The wastewater treatment process requires numerous devices and equipment, one of which is the oxidation tank. An oxidation tank is a wastewater treatment facility that primarily purifies water through biological contact. For example, the Chinese utility model patent CN211471142U, concerning an oxidation tank for domestic wastewater treatment, discloses a domestic wastewater treatment oxidation tank comprising a lower annular oxidation tank and an upper annular oxidation tank. A third oxidation tank, connecting the lower and upper annular oxidation tanks, is located between them, with its bottom sealed to the bottom of the lower annular oxidation tank. This utility model effectively provides a living environment for aerobic and anaerobic bacteria, and, in conjunction with aquatic plants, forms a local ecological balance, thereby treating domestic wastewater.

[0003] The above devices still have some problems in use. During operation, the wastewater flow is relatively short, and each stage of wastewater treatment is prone to being insufficient, which can easily lead to inadequate wastewater treatment. The wastewater discharged from the devices can also cause secondary pollution to the environment and have an impact on the environment. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an oxidation tank for domestic sewage treatment, characterized by comprising an anaerobic treatment device, an anoxic treatment device, and an aerobic treatment device. The anoxic treatment device is mounted on the side of the anaerobic treatment device, and the aerobic treatment device is mounted on the side of the anoxic treatment device.

[0005] The anaerobic treatment device consists of an inlet pipe A, a horizontal pipe A, an inlet valve, branch inlet pipes A, an anaerobic treatment box, an outlet tank A, an outlet pipe A, an outlet valve A, and packing material. The inlet pipe A is installed on one side of the anaerobic treatment box, with an inlet valve at one end. A horizontal pipe A is installed at the lower end of the inlet pipe A. Several branch inlet pipes A are installed on both sides of the horizontal pipe A. Packing material is installed above the horizontal pipe A. An outlet tank A is located inside the anaerobic treatment box at the top, with an outlet pipe A installed at one end. The outlet pipe A passes through an opening in the anaerobic treatment box, and an outlet valve A is installed at one end of the outlet pipe A.

[0006] The anoxic treatment device consists of an inlet pipe B, a horizontal pipe B, branch inlet pipes B, biofilm A, biofilm B, an outlet tank B, an outlet pipe B, an outlet valve B, an outlet tank C, an outlet pipe C, an outlet valve C, and an anoxic treatment tank. One end of the outlet pipe A is connected to the inlet pipe B, and the lower end of the inlet pipe B is connected to the horizontal pipe B. Several branch inlet pipes B are installed on both sides of the horizontal pipe B. Biofilm B is installed above the horizontal pipe B, and biofilm A is installed above the biofilm B. An outlet tank B is located on one side of the upper interior of the anoxic treatment tank, with an outlet pipe B installed at one end, passing through an opening in the anoxic treatment tank. An outlet valve B is installed at one end of the outlet pipe B. An outlet tank C is located on the other side of the upper interior of the anoxic treatment tank, with an outlet pipe C installed at one end, passing through an opening in the anoxic treatment tank. An outlet valve C is installed at one end of the outlet pipe C.

[0007] The aerobic treatment device consists of an inlet pipe C, an inlet pipe D, an aerobic treatment box, partitions, a support, a top plate, an aeration device, slide rail A, slide rail B, a baffle, and a handle. The outlet pipe B is connected to the inlet pipe C, which extends into the aerobic treatment box. The outlet pipe C is connected to the inlet pipe D, which also extends into the aerobic treatment box. Several partitions are installed inside the aerobic treatment box. A support is installed on the outside of the aerobic treatment box. A top plate is installed at the top center of the support. An aeration device is installed below the top plate. Slide rail A is installed on one side of one end of the aerobic treatment box, and slide rail B is installed on the other side of one end of the aerobic treatment box.

[0008] The beneficial effects of this utility model are:

[0009] This utility model discloses an oxidation tank for treating domestic sewage. In use, domestic sewage flows into horizontal pipe A through inlet pipe A, and then into the anaerobic treatment tank through branch inlet pipe A. The sewage accumulates upwards, passes through the packing material, and then flows into outlet pipe A through outlet trough A. The sewage then flows into horizontal pipe B through inlet pipe B, and then into anoxic treatment tank through branch inlet pipe B. The sewage accumulates upwards, passes through biofilm B and biofilm A, and part of it flows into outlet trough B, then into outlet pipe B, and part of it flows into outlet trough C, then into outlet pipe C. The sewage then flows into inlet pipe C through outlet pipe B, and then into aerobic treatment tank. Finally, the sewage flows into inlet pipe D through outlet pipe C, and then into aerobic treatment tank. After aeration treatment, the sewage can flow out after the baffle is lifted. In this wastewater treatment process, wastewater accumulates from the bottom of the anaerobic treatment tank, passes through the packing material, flows into the bottom of the anoxic treatment tank, accumulates again, passes through a double-layer biofilm, and then flows into the aerobic treatment tank. The baffles in the aerobic treatment tank ensure more thorough contact between the wastewater and oxygen during flow, resulting in a longer wastewater flow path and better treatment efficiency. Additionally, the aerobic treatment tank is equipped with a liftable baffle at its tail end, allowing for control of the discharge volume by adjusting the baffle position as needed.
