The partitions between the anaerobic, anoxic, aerobic, sedimentation, and disinfection tanks are sequentially equipped with an overflow port A, multiple evenly distributed connecting holes, an overflow port B, and an overflow port C. This wastewater treatment device adopts an integrated design, reducing energy consumption, floor space, and construction costs, and aims to reduce power consumption by using a water distributor and spherical suspended packing material. However, the following problem remains: the free distribution of the spherical suspended packing material in the water body is not conducive to later maintenance and replacement. Utility Model Content

[0004] The purpose of this invention is to provide an energy-efficient integrated wastewater treatment device with a reasonable structure and reliable operation that solves the above-mentioned problems. It is beneficial for maintaining the packing area, ensuring the continuity of wastewater treatment, further improving wastewater treatment efficiency, and making fuller use of the spherical suspended packing, resulting in better wastewater treatment effect.

[0005] The technical solution of this utility model is: An energy-efficient integrated wastewater treatment device includes a screen well, an equalization tank, an anaerobic tank, an anoxic tank, an aerobic tank, a sedimentation tank, and a disinfection tank arranged sequentially. Its key technical feature is that the aerobic tank employs two aerobic treatment modules connected in series. Each aerobic treatment module includes a tank body, a treatment chamber suspended within the tank body, an extension cover located along the upper edge of the treatment chamber and supported at the top of the tank body, and, from bottom to top, a lower packing cavity, an upper packing cavity, and a water collection cavity located within the treatment chamber. The filling chamber contains spherical suspended packing material and annular aeration chambers arranged around the lower and upper filling chambers. The bottom surface of the treatment chamber, the top surface of the lower filling chamber, and the top surface of the upper filling chamber are all perforated panels. The top surface of the extended cover is equipped with an aerator that communicates with the annular aeration chambers. An overflow weir is provided between the tanks of the two aerobic treatment modules. Water inlet pipes are provided in the water collection chambers of the two aerobic treatment modules. The end of the water inlet pipe of the first aerobic treatment module passes through the side wall of the treatment chamber and overlaps the overflow weir.

[0006] In the aforementioned energy-efficient integrated wastewater treatment device, an overflow weir is provided between the tank body of the second aerobic treatment module and the sedimentation tank, and the end of the water inlet pipe of the second aerobic treatment module passes through the side wall of the treatment chamber and overlaps the overflow weir.

[0007] The aforementioned energy-efficient integrated sewage treatment device has a fixing component on the outer wall of the water inlet pipe that connects to the inner top surface of the expansion cover.

[0008] The aforementioned energy-efficient integrated sewage treatment device has a U-shaped opening on the overflow weir corresponding to the water intake pipeline, and the edge of the extended cover is provided with a water-blocking block that presses against the water intake pipeline to prevent water from being directly discharged from the U-shaped opening.

[0009] The beneficial effects of this utility model are: 1. The two aerobic treatment modules in the aerobic tank can operate continuously and simultaneously, or independently. When not in operation, the inner chamber of the aerobic treatment module can be lifted out of the tank by external force for maintenance of the packing material, etc. This facilitates the maintenance of the packing area, ensures the continuity of wastewater treatment, and further improves wastewater treatment efficiency.

[0010] 2. The water entering the aerobic treatment module tank enters through the bottom surface of the inner chamber of the working aerobic treatment module, then passes sequentially through the lower packing chamber, upper packing chamber, and water collection chamber, and is finally discharged through the water inlet pipe. This constrained water flow path ensures sufficient contact between the water and the spherical suspended packing material in the lower and upper packing chambers, resulting in better water purification.

[0013] The present invention will be described in detail with reference to the accompanying drawings.

[0014] like Figure 1 , Figure 2 As shown, this energy-efficient integrated wastewater treatment device includes, in sequence, a bar screen I, an equalization tank II, an anaerobic tank III, an anoxic tank IV, an aerobic tank V, a sedimentation tank IV, and a disinfection tank VII.

[0015] The aerobic tank V consists of two aerobic treatment modules connected in series.

[0016] The aerobic treatment module includes a tank body 5, a treatment chamber 15 suspended in the tank body 5, an extension cover 1 located along the upper edge of the treatment chamber 15 and supported on the top of the tank body 5, a lower packing chamber 14, an upper packing chamber 13, and a water collection chamber 7 arranged sequentially from bottom to top in the treatment chamber 15, spherical suspended packing material 12 arranged in the lower packing chamber 14 and the upper packing chamber 13, and an annular aeration chamber 11 arranged around the lower packing chamber 14 and the upper packing chamber 13. The bottom surface of the treatment chamber 15, the top surface of the lower packing chamber 14, and the top surface of the upper packing chamber 13 are all perforated panels. The top surface of the extension cover 1 is provided with an aerator 2 communicating with the annular aeration chamber 11.

[0017] An overflow weir 6 is provided between the tanks 5 of the two aerobic treatment modules. Water inlet pipes 4 are provided in the water collection chambers 7 of both aerobic treatment modules. The end of the water inlet pipe 4 of the first aerobic treatment module passes through the side wall of the inner treatment chamber 15 and overlaps the overflow weir 6. An overflow weir 10 is provided between the tank of the second aerobic treatment module and the sedimentation tank. The end of the water inlet pipe 4 of the second aerobic treatment module passes through the side wall of the inner treatment chamber 15 and overlaps the overflow weir 10. A fixing member 3 is provided on the outer wall of the water inlet pipe 4, connecting to the inner top surface of the expansion cover 1. U-shaped openings 9 corresponding to the water inlet pipes 4 are provided on the overflow weirs 6 and 10. A water-blocking block 8 is provided on the edge of the expansion cover 1, pressing against the water inlet pipe 4 to prevent water from being directly discharged through the U-shaped openings 9.

[0018] Working principle: 1. Wastewater enters the screen well I through the drainage system. After removing solid debris, it passes through the equalization tank II, anaerobic tank III, anoxic tank IV, aerobic tank V, sedimentation tank IV, and disinfection tank VII for purification.

[0019] 2. The two aerobic treatment modules in the aerobic tank can operate continuously and simultaneously, or independently. When the first aerobic treatment module operates independently, the tank body 5 of the second aerobic treatment module receives water from the first aerobic treatment module, and then its overflow weir 10 transfers the water to the sedimentation tank IV. When the second aerobic treatment module operates independently, the tank body 5 of the first aerobic treatment module receives water from the anoxic tank, and then its overflow weir 6 transfers the water to the second aerobic treatment module. The treatment chamber 15 of the aerobic treatment module that is not in operation is lifted out of the tank body 5 by external force for maintenance of the packing material, etc.

[0020] 3. The water entering the tank 5 enters through the bottom surface of the treatment chamber 15 of the working aerobic treatment module, then passes sequentially through the lower packing chamber 14, the upper packing chamber 13, and the water collection chamber 7, and is finally discharged through the water inlet pipe 4. During this process, the water fully contacts the spherical suspended packing material 12 in the lower packing chamber 14 and the upper packing chamber 13, resulting in a better purification effect on the water.

[0021] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this utility model.
