[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Specific implementation examples:
[0026] like Figures 1-5As shown, a small-scale household rainwater and sewage separation and storage device includes a storage tank 1. Inside the storage tank 1, a first partition 2, a second partition 3, a third partition 4, a fine screen 5, and a pretreatment screen 6 are sequentially fixedly connected. The third partition 4 and the inner wall of the storage tank 1 form a pretreatment space 7. The fine screen 5 and the pretreatment screen 6 are located within the pretreatment space 7. The space between the third partition 4 and the second partition 3 forms a biological treatment space 8. The space between the second partition 3 and the first partition 2 forms a sedimentation space 9. The space between the first partition 2 and the inner wall of the storage tank 1 forms a water storage space 10. Hanging components 11 are installed on the second partition 3 and the third partition 4. A biological treatment component 12 is installed on the hanging components 11. The hanging components 11 are detachably connected to the second partition 3 and the third partition 4. Both the plate 3 and the third partition 4 are provided with L-shaped grooves 13 for sliding installation of the mounting assembly 11. The mounting assembly 11 includes a sliding rod 111. One end of the sliding rod 111 slides in the groove 13 of the second partition 3, and the other end slides in the groove 13 of the third partition 4. Two mounting plates 112 are fixedly connected to the side of the two sliding rods 111 that are close to each other. Multiple suspension rods 113 are fixedly connected at equal intervals between the two mounting plates 112 on the same sliding rod 111. The suspension rods 113 are used to install the biological treatment assembly 12. Connecting plates 114 are fixedly connected to the side of the mounting plates 112 on the two sliding rods 111 that are close to each other. Four connecting plates 114 are rotatably connected to the same connecting rod 115. A hanging ring 116 is fixedly connected to the connecting rod 115. Open the storage tank 1, and use the hook to suspend it on the lifting ring 116. Pull the lifting ring 116 upward to make each connecting plate 114 rotate relative to the connecting rod 115. The two sliding rods 111 slide closer and the included angle between the connecting plates 114 becomes smaller until the end of the sliding rod 111 slides to the opening of the slide groove 13. Then the mounting assembly 11 and the biological treatment assembly 12 installed on the mounting assembly 11 can be pulled out of the storage tank 1, which is convenient for replacing the biological treatment assembly 12.
[0027] like Figures 1-5 As shown, the second partition 3 and the third partition 4 are each provided with two symmetrically arranged sliding grooves 13, and the two sliding grooves 13 located on the same partition (such as the same second partition 3) are not connected.
[0028] like Figures 1-5 As shown, water passage holes 14 are provided on the first partition 2, the second partition 3 and the third partition 4, so that the treated wastewater can pass through the pretreatment space 7, the biological treatment space 8 and the sedimentation space 9 in sequence, and finally enter the water storage space 10.
[0029] like Figures 1-5As shown, the biological treatment component 12 includes a hanging rope 121 that is tied and fixed to the suspension rod 113. The hanging rope 121 is a corrosion-resistant polyester fiber rope, and a biological treatment material 122 is inserted through the hanging rope 121. The biological treatment material 122 is an elastic open-cell foam suspended biological packing. Through the suspended open-cell foam suspended biological packing, the sewage that has been pretreated by the pretreatment screen 6 and the fine screen screen 5 is further purified. The elastic open-cell foam suspended biological packing can carry a large number of organisms to purify the sewage, and the cost is low.
[0030] like Figures 1-5 As shown, a locking block 117 is fixedly connected to the connecting plate 114 on one side. During the process of removing the mounting assembly 11 from the second partition 3 and the third partition 4, when the sliding rod 111 moves to the opening of the slide groove 13, the locking block 117 just abuts against the connecting plate 114 on the other side (connecting plate 114 on different sliding rods 111), so that the minimum included angle between the two connecting plates 114 is a fixed value, which is thirty degrees in this embodiment. After replacing the biological treatment component 12, the hanging component 11 and the biological treatment component 12 are placed into the storage tank 1 by suspending the hanging ring 116 with the hook. Under the action of gravity, the connecting plates 114 on both sides rotate and move closer to each other until the minimum included angle is reached (that is, the locking block 117 just abuts against the connecting plate 114 on the other side). This makes it easy to slide the end of the sliding rod 111 into the opening of each adjacent slide groove 13. Then, the hanging ring 116 is pressed down to make the end of the sliding rod 111 slide into its respective slide groove 13 until the hanging component 11 is laid flat, thus completing the replacement of the biological treatment component 12.
[0031] like Figures 1-5 As shown, the storage tank 1 is connected to a sewage inlet pipe 15 and a rainwater inlet pipe 16. One end of the sewage inlet pipe 15 is located in the pretreatment space 7 and is located on the side of the pretreatment grid 6 away from the fine screen grid 5. The other end of the sewage inlet pipe 15 is connected to a household sewage pipe, such as a kitchen water drain pipe. Both the pretreatment grid 6 and the fine screen grid 5 are metal grids with an anti-corrosion coating on their surfaces. The mesh size of the pretreatment grid 6 is larger than that of the fine screen grid 5. After entering the pretreatment space 7, the wastewater first passes through the pretreatment screen 6 to intercept larger solid waste, particles, or fibers. Then, it enters the space between the pretreatment screen 6 and the fine screen 5, where the fine screen 5 intercepts smaller solid waste, particles, or fibers. The wastewater then enters the biological treatment space 8 through the water passage holes 14 on the third partition 4. The biological treatment agent 122 further purifies the wastewater. The wastewater then enters the sedimentation space 9 through the water passage holes 14 on the second partition 3 to settle. The clearer water then enters the water storage space 10 through the water passage holes 14 on the first partition 2. The clear water that has been treated meets the discharge standards and can be used for activities such as watering plants, thus achieving the effect of resource reuse.
[0032] likeFigures 1-5 As shown, the rainwater inlet pipe 16 is directly connected to the water storage space 10. A rainwater filter 17 is installed on the inner wall of the storage tank 1 within the water storage space 10. The rainwater filter 17 is a commercially available automatic rainwater filter, model LD-312. The rainwater inlet pipe 16 is connected to the inlet end of the rainwater filter 17, and the other end of the rainwater inlet pipe 16 is connected to the building's downpipe for collecting rainwater from the roof. The outlet end of the rainwater filter 17 is aligned with the bottom of the water storage space 10. By connecting the rainwater inlet pipe 16 and the sewage inlet pipe 15 to different water treatment spaces, the device achieves the effect of separating rainwater and sewage.
[0033] like Figures 1-5 As shown, the storage tank 1 is also connected to a water pump 18. One end of the water pump 18 located inside the water storage space 10 is connected to a water pump 19, which can pump the clean water in the water storage space 10 to the outside of the storage tank 1 for use.
[0034] like Figures 1-5 As shown, the storage tank 1 is equipped with a tank cover 20. Opening the tank cover 20 facilitates observation, inspection and cleaning of the inside of the storage tank 1.
[0035] The working principle of a small-scale household rainwater and sewage separation and storage device in this embodiment is as follows: During use, sewage enters the pretreatment space 7 through the sewage inlet pipe 15. First, solid waste, particles, or fibers are intercepted by the pretreatment screen 6 and the fine screen 5. Then, the sewage enters the biological treatment space 8 through the water passage 14 on the third partition 4, where the biological treatment material 122 further purifies the sewage. Then, the sewage enters the sedimentation space 9 through the water passage 14 on the second partition 3 for sedimentation. The clearer water then enters the water storage space 10 through the water passage 14 on the first partition 2, completing the rainwater and sewage separation treatment. If the biological treatment component 12 needs to be replaced, the storage tank 1 is opened, and the device is suspended on the hanging ring 116 by using a hook. The hanging ring 116 is pulled upward to rotate each connecting plate 114 relative to the connecting rod 115. As the two sliding rods 111 slide closer together, the included angle between the connecting plates 114 decreases until the end of the sliding rod 111 slides to the opening of the groove 13. This allows the mounting assembly 11 and the biological treatment assembly 12 installed on the mounting assembly 11 to be pulled out of the storage tank 1 for replacement. After replacement, the mounting assembly 11 and the biological treatment assembly 12 are placed into the storage tank 1 by suspending the lifting ring 116 with the hook. Under the action of gravity, the connecting plates 114 on both sides rotate and move closer to each other until the minimum included angle is reached. This makes it easier to slide the end of the sliding rod 111 into the opening of each adjacent groove 13. Then, the lifting ring 116 is pressed down to make the end of the sliding rod 111 slide into its respective groove 13 until the mounting assembly 11 is laid flat, thus completing the replacement of the biological treatment assembly 12.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
