Wastewater reuse can reduce the demand for freshwater resources and lessen the burden on the environment. However, existing wastewater reuse treatment plants have complex connection methods between various treatment units, making installation and disassembly difficult, which hinders equipment maintenance and upgrades. Furthermore, each treatment unit has a single function, and when treating wastewater from different sources, such as domestic sewage and industrial wastewater, the pollutant composition varies significantly, making it impossible to flexibly combine units according to actual water quality and treatment needs.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 6This utility model provides a technical solution: a modular greywater reuse treatment device, including a pretreatment unit 1 and a connecting component 5. A biological treatment unit 2, a deep treatment unit 3 and a disinfection unit 4 are arranged sequentially on one side of the pretreatment unit 1. The pretreatment unit 1, the biological treatment unit 2, the deep treatment unit 3 and the disinfection unit 4 are detachably connected sequentially through the connecting component 5. The connecting component 5 includes a connecting block 501 fixedly connected to both sides of each unit. An inlet pipe 6 and an outlet pipe 7 are fixedly connected to both sides of the pretreatment unit 1, the biological treatment unit 2, the deep treatment unit 3 and the disinfection unit 4, respectively. The outlets of the inlet pipe 6 and the outlet pipe 7 are both matched with the connecting block 501.

[0024] In this embodiment, a water passage groove 502 is provided through one side of the connecting block 501. The inlet pipe 6 and outlet pipe 7 are respectively fixedly connected in the water passage groove 502. Sealing gaskets 503 are fixedly connected to opposite sides of two adjacent connecting blocks 501. A displacement groove 504 communicating with the water passage groove 502 is provided inside the connecting block 501. A flow intercepting block 505 with an inclined edge is slidably fitted on the inner wall of the displacement groove 504 and cooperates with the water passage groove 502. A pull rod 506 extending through the outside of the connecting block 501 is fixedly connected to one side of the flow intercepting block 505. A sliding hole 507 extending into the displacement groove 504 is provided on the outer side of the connecting block 501. The pull rod 506 is slidably fitted in the sliding hole 507. A spring 508 is fixedly connected between one side of the flow block 505 and the inner wall of the displacement groove 504. A water flow hole 509 is opened through one side of the flow block 505. The water flow hole 509 cooperates with the water passage groove 502. A positioning post 510 is fixedly connected to one side of the connecting block 501. A positioning groove 511 is opened on one side of the connecting block 501. The positioning posts 510 on opposite sides of two adjacent connecting blocks 501 cooperate with the positioning groove 511. The end of the positioning post 510 is arc-shaped and abuts against the inclined side of the flow block 505. A fixing groove 512 is opened inward on the outer side of the positioning post 510. A fixing post 513 that cooperates with the fixing groove 512 is fixedly connected to the side of the flow block 505 near the inclined side.

[0025] Specifically, when it is necessary to assemble each processing unit, the adjacent connecting blocks 501 are initially positioned by the cooperation of the positioning post 510 and the positioning groove 511. The arc-shaped structure at the end of the positioning post 510 contacts the inclined side of the intercepting block 505. During the positioning process, the intercepting block 505 is pushed to overcome the resistance of the spring 508 and slide into the displacement groove 504, so that the water flow hole 509 on the intercepting block 505 is aligned with the water passage groove 502. The water inlet pipe 6 and the water outlet pipe 7 are connected by the water passage groove 502 and the water flow hole 509. At the same time, the sealing gasket 503 ensures the sealing of the connection and prevents water leakage.

[0026] In this embodiment, a sand filter grid 8 is fixedly connected to the inner wall of the pretreatment unit 1, and a sand discharge port 9 located on the upper side of the sand filter grid 8 is opened through the inner wall of the pretreatment unit 1. A partition 10 is fixedly connected inside the biological treatment unit 2, and multiple water passage holes 11 are opened on the partition 10. The partition 10 divides the interior of the biological treatment unit 2 into an anaerobic reaction zone 12 and an aerobic reaction zone 13. A packing layer 14 is fixedly connected inside the anaerobic reaction zone 12. The biological treatment unit 2 is fixedly connected to... An aeration pipe 15 is connected to an external air source. The aeration pipe 15 is fixedly connected to multiple aeration heads 16 that penetrate into the aerobic reaction zone 13. Multiple filter tanks 17 connected by pipelines are fixedly connected inside the deep treatment unit 3. The water inlet pipe 6 and water outlet pipe 7 on the deep treatment unit 3 are respectively connected to the water inlet and water outlet of the filter tank 17. An ultraviolet disinfection lamp tube 18 is fixedly connected to the top of the inner wall of the disinfection unit 4. An ozone generator 19 is fixedly connected to the inner wall of the disinfection unit 4.

[0027] Specifically, the reclaimed water first enters the pretreatment unit 1, where larger particles of impurities are intercepted by the sand filter screen 8, and the deposited silt can be discharged through the sand outlet 9. Then, the water flows into the biological treatment unit 2. In the anaerobic reaction zone 12, the packing layer 14 provides an attachment and growth environment for microorganisms, which decompose organic matter in the water. The water then flows into the aerobic reaction zone 13 through the water passage holes 11 of the baffle 10. Air is introduced into the aerobic reaction zone 13 through the aeration pipe 15 and the aeration head 16, and the aerobic microorganisms further degrade pollutants under sufficient oxygen conditions. Next, the water flows into the deep treatment unit 3, where multiple filter tanks 17 connected by pipelines perform deep filtration of the reclaimed water, removing residual impurities and some pollutants. Finally, in the disinfection unit 4, the ultraviolet disinfection lamp tube 18 and the ozone generator 19 work together to kill bacteria, viruses and other microorganisms in the water by using the photochemical effect of ultraviolet light and the strong oxidizing properties of ozone, thus purifying the reclaimed water.

[0028] When the modular greywater reuse treatment unit is in operation, it is first assembled into units through connecting components 5. The positioning posts 510 and positioning grooves 511 of adjacent connecting blocks 501 cooperate to achieve initial positioning. The end of the positioning post 510 pushes the intercepting block 505 to slide against the resistance of the spring 508, so that the water outlet 509 is aligned with the water passage 502, and the inlet pipe 6 and outlet pipe 7 are connected. The sealing gasket 503 ensures a seal. After assembly, greywater enters the pretreatment unit 1, the sand filter 8 intercepts large particles of impurities, and the silt is discharged from the sand discharge port 9; then it flows into In biological treatment unit 2, anaerobic microorganisms on the packing layer 14 decompose organic matter in the anaerobic reaction zone 12. The decomposed organic matter enters the aerobic reaction zone 13 through the water passage 11 of the partition 10. The aeration pipe 15 supplies oxygen through the aeration head 16, and the aerobic microorganisms further degrade pollutants. Then the water flows into the deep treatment unit 3, where multiple interconnected filter tanks 17 deeply filter residual impurities and pollutants. Finally, in the disinfection unit 4, the ultraviolet disinfection lamp tube 18 uses photochemical action and the ozone generator 19 uses strong oxidizing properties to synergistically kill microorganisms, completing the purification of greywater.
