[0028] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an integrated wastewater treatment device, which includes: a biochemical tank 1, an intermediate tank 2, and a disinfection tank 3;

[0031] The biochemical tank 1 is provided with an aerator 4 and a packing layer 5 from bottom to top inside. The upper side of the biochemical tank 1 is provided with a water inlet, and the other side of the upper end of the biochemical tank 1 is connected to one end of the drainage pipe 6.

[0032] The intermediate box 2 is provided with a vertical guide pipe 7. The lower end of the vertical guide pipe 7 is connected to the guide cone 8. The guide cone 8 is provided with a guide cone 9. There is a gap between the guide cone 8 and the guide cone 9. The other end of the guide pipe 6 extends to the inner side of the upper end of the vertical guide pipe 7. The upper side wall of the intermediate box 2 is provided with a drain outlet.

[0033] The upper side of the disinfection box 3 is connected to the drain outlet.

[0034] The working process of the integrated wastewater treatment device is as follows:

[0035] The wastewater to be treated enters the biochemical tank 1 through the inlet. At the same time, the aerator 4 sprays air into the wastewater to increase the dissolved oxygen in the wastewater. The packing layer 5 is made of Pall ring packing. After the dissolved oxygen is increased, the wastewater enters the vertical guide pipe 7 through the diversion pipe 6 and settles in the vertical guide pipe 7. It spreads to the bottom and periphery of the intermediate tank 2 through the gap between the guide cone 8 and the guide cone 9. The solid components in the wastewater settle in the middle and towards the bottom. The clear liquid enters the disinfection tank 3 from the drain outlet.

[0036] During the above process, the wastewater flows through each tank in sequence, eliminating pollutants in the wastewater and improving treatment efficiency.

[0037] like Figure 1 and Figure 3 As shown, specifically, it also includes a feeding funnel 10, a hollow ball 11, and a stepper motor. The lower end of the feeding funnel 10 is connected to the upper end of the discharge pipe 12, and the lower end of the discharge pipe 12 corresponds to the upper end of the vertical guide pipe 7. The hollow ball 11 is rotatably disposed on the inner edge of the lower end of the feeding funnel 10. The outer wall of the lower end of the feeding funnel 10 is fixedly connected to the stepper motor. The output shaft of the stepper motor is coaxially connected to the radial axis of the hollow ball 11. The hollow ball 11 has an opening parallel to the radial axis.

[0038] Sodium sulfide granules are filled into the feeding hopper 10. The stepping angle of the stepper motor is controlled by the controller to flip the opening of the hollow ball 11 up and down. When the opening of the hollow ball 11 is facing upward, the sodium sulfide granules in the feeding hopper 10 fall into the hollow ball 11. When the opening of the hollow ball 11 is facing downward, the sodium sulfide granules in the hollow ball 11 enter the vertical guide pipe 7 through the discharge pipe 12, thereby realizing the quantitative addition of sodium sulfide, so that heavy metal ions form insoluble metal sulfides and improve the heavy metal removal rate.

[0039] Specifically, the top wall of the biochemical tank is equipped with an oxidation-reduction potential detector, a sludge concentration detector, a dissolved oxygen detector, a pH detector, and a temperature detector.

[0040] In a specific embodiment, an interception net 13 is also included, which is disposed at one end of the drainage tube 6.

[0041] In this embodiment, the interception net 13 is made of fiberglass, and the edge of the interception net 13 is fixedly connected to the other side wall of the upper end of the biochemical box 1 to prevent the filler from entering the drainage pipe 6.

[0042] Specifically, it also includes a rinsing mechanism, which includes a rinsing pump 14 and a spray head 15. The inlet pipe of the rinsing pump 14 extends below the liquid level of the disinfection tank 3, and the outlet pipe of the rinsing pump 14 is connected to the spray head 15. The spray direction of the spray head 15 is towards the mesh surface of the interception net 13, for periodically backwashing the interception net 13.

[0043] In a specific embodiment, it also includes an overflow weir 16, which is arranged in a ring around the upper inner edge of the intermediate box 2, and the overflow weir 16 and the drain outlet are at the same height.

[0044] In this embodiment, specifically, in the intermediate tank 2, the upper clear liquid in the wastewater overflows outward along the inner side wall of the overflow weir 16 and is discharged from the drain outlet into the intermediate tank 2, thereby improving the efficiency of separation between the upper clear liquid and the lower sediment in the intermediate tank 2.

[0045] In a specific embodiment, a biochemical blower 17 is also included, and the exhaust pipe 26 of the biochemical blower 17 is connected to the aerator 4.

[0046] In this embodiment, the biochemical blower 17 provides a continuous airflow to the aerator 4;

[0047] There are multiple aerators 4, which are arranged in a matrix and connected to the pipe wall of the bottom pipe of the biochemical tank 1. The exhaust pipe 26 of the biochemical blower 17 is connected to the bottom pipe, so that multiple aerators 4 can simultaneously spray air into the wastewater to increase dissolved oxygen.

[0048] In a specific embodiment, a phosphorus removal mechanism is also included, which includes a preparation tank 18 and a transfer pump 19. The inlet of the transfer pump 19 is connected to the preparation tank 18, and the outlet of the transfer pump 19 is connected to the upper end of the vertical guide pipe 7.

[0049] In this embodiment, specifically, the preparation tank 18 is filled with PAC / PAM solution, which is pressurized by the transfer pump 19 and added to the vertical guide pipe 7. The PAC / PAM solution is added along with the wastewater to remove phosphorus-containing components from the wastewater.

[0050] In a specific embodiment, a sodium hypochlorite generator 20 is also included, which is connected to the top wall of the disinfection box 3.

[0051] In this embodiment, specifically, after being treated by the biochemical tank 1 and the intermediate tank 2, the wastewater reaches the disinfection tank 3, where bacteria in the wastewater are also removed by the disinfection of sodium hypochlorite, further ensuring the quality of wastewater treatment.

[0052] In a specific embodiment, a sedimentation tank 21 is also included, the upper end of which is connected to the water inlet.

[0053] In this embodiment, the incineration flushing wastewater first enters the sedimentation tank 21. When the sedimentation tank 21 is full, the upper layer of liquid in the sedimentation tank 21 enters the biochemical tank 1, while the pollutants with a higher specific gravity in the wastewater settle to the bottom of the sedimentation tank 21, reducing the load on subsequent wastewater treatment.

[0054] In a specific embodiment, it also includes an ultraviolet lamp 22, which is installed on the top wall of the disinfection box 3.

[0055] In this embodiment, in addition to the sterilization by sodium hypochlorite, ultraviolet lamp 22 assists in the sterilization of bacteria in the gas phase space of the disinfection box 3, thereby improving the completeness of bacterial sterilization.

[0056] In a specific embodiment, it also includes two first pressure caps 23. The top wall of the sedimentation tank 21 is connected to the lower end of the first cleaning pipe 24, the top wall of the intermediate box 2 is connected to the lower end of the second cleaning pipe 25, and the top wall of the disinfection box 3 is connected to the exhaust pipe 26. The two first pressure caps 23 respectively cover the upper end of the first cleaning pipe 24 and the upper end of the second cleaning pipe 25.

[0057] In this embodiment, specifically, based on the synergistic sterilization of sodium hypochlorite and ultraviolet lamp 22, the bacteria contained in the gas in the upper space of the disinfection box 3 are reduced, and when it is discharged through the exhaust pipe 26, the number of bacteria discharged is also less. At the same time, because the exhaust pipe 26 is provided, the biochemical box 1, the intermediate box 2 and the disinfection box 3 become atmospheric pressure containers, which prevents the wastewater from not flowing due to pressure buildup.

[0058] During the operation of this device, the first cover 23 is closed on the upper end of the first cleaning pipe 24 and the upper end of the second cleaning pipe 25 to prevent exhaust gas from escaping. After long-term operation of this device, a large amount of sludge will accumulate at the bottom of each container. At this time, the first cover can be removed, and the hose of the cleaning vehicle can be extended downward into each container along the first cleaning pipe 24 or the second cleaning pipe 25 so that the sludge in each container can be sucked out, thereby maintaining the initial wastewater treatment capacity of each container.

[0059] In a specific embodiment, it also includes a plurality of baffles 27, which are arranged alternately in the disinfection box 3 to form a baffle channel. One end of the baffle channel is connected to the drain outlet, and the other end of the baffle channel is connected to the temporary storage tank through a booster pump.

[0060] In this embodiment, the wastewater discharged from the intermediate tank 2 flows through the baffle channel, increasing the residence time of the wastewater in the disinfection tank 3. This improves the effectiveness of the disinfection by sodium hypochlorite and ultraviolet lamp 22. The disinfected water is then pumped to the temporary storage tank by the booster pump to further ensure the quality of wastewater disinfection.

[0061] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
