[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] Reference Figure 1-4 This utility model embodiment discloses an integrated device for turning wastewater into reusable greywater, which includes a cylinder 1. The top of the cylinder 1 is provided with a wastewater inlet 7, and the inside of the cylinder 1 is provided with an hourglass-shaped water inlet chamber 15. A screen 21 is fixedly connected to the bottom of the hourglass-shaped water inlet chamber 15. After the wastewater flows in from the wastewater inlet 7 at the top of the cylinder 1, it first enters the hourglass-shaped water inlet chamber 15. The hourglass-shaped structure of the chamber can slow down the water flow speed through the change of cross section, so that large particles of impurities in the wastewater will initially settle under the action of gravity. The bottom screen 21 further intercepts suspended solids, such as fibers and silt, to avoid clogging the subsequent treatment unit. A biofilm reaction zone 17 is provided inside the cylinder 1. The biofilm reaction zone 17 is filled with several suspended biological packing materials 10. A baffle 16 is fixedly connected to the bottom of the biofilm reaction zone 17, and an annular aeration pipe 12 is fixedly connected to the baffle 16. A dissolved oxygen sensor 9 is installed at the top of the biofilm reaction zone 17. Filtered sewage enters the biofilm reaction zone 17. The filled suspended biological packing materials 10 are dynamically suspended with the water flow. The biofilm attached to its surface contains a large number of degrading bacteria. The annular aeration pipe 12 on the baffle 16 delivers air through the aeration blower 2 to form a uniform bubble flow, providing oxygen required for the metabolism of aerobic microorganisms. The dissolved oxygen sensor 9 at the top monitors the dissolved oxygen concentration in real time, and the data is transmitted to the control console 4 to automatically adjust the aeration rate.

[0020] The lower end of the biofilm reaction zone 17 is provided with an ultraviolet disinfection zone 18. A ring-shaped ultraviolet lamp tube 13 is fixedly connected to the bottom of the ultraviolet disinfection zone 18. The biologically treated wastewater enters the ultraviolet disinfection zone 18, and the ring-shaped ultraviolet lamp tube 13 at the bottom emits ultraviolet light, which achieves sterilization and disinfection through photochemical action. The ring layout makes the ultraviolet radiation evenly cover the entire cross section.

[0021] A deep filtration zone 19 is provided at the lower end of the ultraviolet disinfection zone 18. Four filter cartridges 14 are fixedly connected in the deep filtration zone 19. The filter cartridges 14 are filled with activated carbon. After disinfection, the wastewater enters the deep filtration zone 19. The granular activated carbon in the four parallel filter cartridges 14 uses its microporous structure to adsorb residual pollutants and remove color, odor, trace organic matter and heavy metal ions.

[0022] The lower end of the deep filtration zone 19 is provided with an hourglass-shaped water outlet chamber 20. The lower end of the hourglass-shaped water outlet chamber 20 is fixedly connected to a greywater outlet 8. The greywater outlet 8 has a built-in valve. The filtered greywater enters the hourglass-shaped water outlet chamber 20. The constriction design of this chamber can stabilize the water flow pressure and avoid fluctuations from affecting subsequent reuse. The greywater outlet 8 has a built-in electric valve that is linked to the control console 4 for control.

[0023] Both the ultraviolet disinfection zone 18 and the deep filtration zone 19 are fixedly connected to a partition 16 at their lower ends. A telescopic plate 11 is installed on the partition 16. The telescopic plate 11 is electrically driven. After each functional zone completes its cleaning and purification task, the telescopic plate 11 is opened to allow water to flow into the next functional zone.

[0024] A blower bracket 3 is fixedly connected to the outside of the cylinder 1. An aeration blower 2 is fixedly connected to the blower bracket 3. The aeration blower 2 is connected to the cylinder 1. The aeration blower 2 is a Roots blower. The air volume is automatically adjusted according to the volume of the biofilm reaction zone 17. It is connected to the annular aeration pipe 12 through a high-pressure resistant pipe.

[0025] A control console bracket 5 is fixedly connected to the outside of the cylinder 1, and a control console 4 is fixedly connected to the control console bracket 5. The control console 4 integrates a PLC control system, which monitors the equipment operation status in real time through a sensor network. It can also automatically adjust the flow rate of each treatment zone according to the influent flow rate, receive data from the dissolved oxygen sensor probe 9, dynamically adjust the aeration volume, and finally record the operation log and provide early warning of faults. It supports remote monitoring and parameter setting, and realizes unattended operation.

[0026] The bottom of the cylinder 1 is fixedly connected to the cylinder support 6. The cylinder support 6 is treated with anti-corrosion and can withstand several times the weight load when the equipment is fully loaded. The height of the support is designed to reserve space for bottom maintenance, while improving the equipment's vibration resistance and ensuring stable operation under dynamic loads such as pump start-up and shutdown and aeration disturbance.

[0027] Working Principle: During operation, wastewater enters the hourglass-shaped inlet chamber 15 through the wastewater inlet 7 and flows into the biofilm reaction zone 17 under gravity. Some waste material is screened out by the screen 21. In the biofilm reaction zone 17, high-pressure air generated by the aeration blower 2 is blown in through the annular aeration pipe 12 and reacts with the suspended biological packing material 10 to purify the water. The dissolved oxygen sensor 9 detects the oxygen content in the reaction zone. Intermittent aeration control achieves alternating periods of anoxic and aerobic conditions. Then, the partition 16 opens the telescopic plate 11, allowing the wastewater to enter the ultraviolet disinfection zone 18 and be irradiated by the annular ultraviolet lamp 13. After ultraviolet disinfection, the wastewater enters the deep filtration zone 19. The water flows in from the top of the filter cartridge 14, passes through the activated carbon filter media from the inside out, and flows out from the bottom. Finally, the purified wastewater... The wastewater is collected from the greywater outlet 8 through the hourglass-shaped outlet chamber 20. The overall effect is that the wastewater is collected through the hourglass-shaped inlet chamber 15 inside the cylinder 1 and the built-in screen 21, and gravity self-screening is completed at the wastewater inlet 7, eliminating the need for an independent grid unit. In the biofilm reaction zone 17, the suspended biological packing 10 and the dissolved oxygen sensor 9 are linked to the annular aeration pipe 12. Through the intermittent aeration intelligent control of the aeration blower 2, an alternating environment of anoxic and aerobic conditions is created in the single reaction zone, which simultaneously enhances the efficiency of denitrification and carbon removal. At the same time, the cylinder 1 adopts a vertical stacked layout, integrating the biofilm reaction zone 17, the ultraviolet disinfection zone 18, the deep filtration zone 19 and other functional areas into one, and combined with the openable and closable telescopic plate 11 to achieve gravity flow treatment. The annular ultraviolet lamp 13 in the ultraviolet disinfection zone 18 can sterilize without dead corners, and the filter cartridge 14 in the deep filtration zone 19 performs physical adsorption. The two form a double barrier.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
