Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an integrated domestic sewage treatment device. Background Technology

[0002] Domestic sewage is wastewater discharged from residents' daily lives. It contains a large amount of organic matter and pathogenic microorganisms. Bacteria and pathogenic microorganisms decompose the organic matter in domestic sewage into inorganic matter for energy and multiply rapidly. Moreover, the decomposition process consumes dissolved oxygen in the water. Under anaerobic conditions, pollutants decompose and deteriorate water quality. Therefore, domestic sewage must be treated before it can be discharged.

[0003] When treating wastewater, the wastewater passes through an anaerobic tank, an anoxic tank, an aerobic tank, a sedimentation tank, and a disinfection tank in sequence before being released. After the wastewater is treated, a lot of sediment will accumulate at the bottom of the sedimentation tank, so it is necessary to clean the sediment at the bottom of the sedimentation tank. However, the sediment solidifies after it accumulates, making it inconvenient to clean. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, a large amount of sediment will accumulate at the bottom of the sedimentation tank after wastewater treatment, which will solidify and be inconvenient to clean. Therefore, an integrated domestic sewage treatment device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Design an integrated domestic sewage treatment device, including a treatment tank. The treatment tank contains, along its length, an anaerobic tank, an anoxic tank, an aerobic tank, a sedimentation tank, and a disinfection tank. A sludge pump is fixedly connected to the treatment tank. The inlet end of the sludge pump is connected to a sludge suction pipe. One end of the sludge suction pipe extends to the bottom of the sedimentation tank. An installation plate is fixedly connected to the upper end of the sedimentation tank. A geared motor is fixedly connected to the installation plate. The output end of the geared motor extends to the bottom of the sedimentation tank and is fixedly connected to an agitator.

[0006] Preferably, a gap is provided between the agitator blade and the bottom of the sedimentation tank.

[0007] Preferably, one end of the suction pipe is connected to a U-shaped pipe, and several through holes are equally spaced on both sides of the U-shaped pipe along the length direction.

[0008] The integrated domestic sewage treatment equipment proposed in this utility model has the following advantages: The sludge pump is started by powering on. After the sludge pump starts, it sucks up the sediment through the suction pipe. At the same time, the geared motor is started by powering on. After the geared motor starts, it drives the agitator to rotate. The rotation loosens the sediment accumulated at the bottom of the sedimentation tank, creating gaps between the accumulated sediment and reducing the adhesion between the sediment, making it easier to treat the sediment at the bottom.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0012] Example 1: Refer to Figure 1-3 An integrated domestic sewage treatment device includes a treatment tank 1. Within the treatment tank 1, an anaerobic tank 2, an anoxic tank 3, an aerobic tank 4, a sedimentation tank 5, and a disinfection tank 6 are arranged sequentially along the length direction. A sludge pump 7 is fixedly connected to the treatment tank 1. The inlet end of the sludge pump 7 is connected to a sludge suction pipe 8. One end of the sludge suction pipe 8 extends to the bottom of the sedimentation tank 5. An mounting plate 9 is fixedly connected to the upper end of the sedimentation tank 5. A geared motor 10 is fixedly connected to the mounting plate 9. The output end of the geared motor 10 extends to the bottom of the sedimentation tank 5 and is fixedly connected to an agitator 11. A gap is provided between the agitator 11 and the bottom of the sedimentation tank 5. One end of the sludge suction pipe 8 is connected to a U-shaped pipe 12. Several through holes 13 are equally spaced on both sides of the U-shaped pipe 12 along the length direction.

[0013] Work process: Domestic sewage is treated sequentially through anaerobic tank 2, anoxic tank 3, aerobic tank 4, sedimentation tank 5, and disinfection tank 6 before being discharged. When treating the sediment at the bottom of sedimentation tank 5, sludge pump 7 is powered on and started. After starting, sludge pump 7 sucks up the sediment through suction pipe 8. Suction pipe 8 sucks up the sediment through U-shaped pipe 12. U-shaped pipe 12 sucks up the sediment at the bottom of sedimentation tank 5 through through hole 13. At the same time, geared motor 10 is powered on and started. After starting, geared motor 10 drives agitator 11 to rotate. The rotation of agitator 11 loosens the sediment accumulated at the bottom of sedimentation tank 5, creating gaps between the accumulated sediment and reducing the adhesion between the sediment, making it easier to treat the sediment at the bottom.
