Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a high-efficiency and compact wastewater treatment sedimentation tank. Background Technology

[0002] Wastewater treatment sedimentation tanks are an important component of wastewater treatment systems. Their main function is to remove suspended solids (SS) and some heavy metal ions from wastewater through physical sedimentation. The working principle of sedimentation tanks is to use gravity to allow suspended solids in wastewater to naturally settle to the bottom during static or slow flow, thereby achieving solid-liquid separation.

[0003] The prior art document, "A High-Efficiency Compact Wastewater Treatment Sedimentation Tank," (CN222900499U), utilizes a combination of a cylindrical body, guide blocks, bearings, impeller blades, connecting rods, blades, and a filter screen. During operation, wastewater is introduced into the cylindrical body through an inlet pipe. The impeller blades generate impact force during this process, driving the rotation of the connecting plate, connecting rods, and blades. The blades pulverize solid impurities, which are then filtered through the filter screen inside the filter chamber before being discharged into the sedimentation tank itself. This improves the efficiency of wastewater treatment and prevents the accumulation of large amounts of solid impurities inside the sedimentation tank, reducing the difficulty of cleaning for operators and thus enhancing the practicality of the wastewater treatment sedimentation tank.

[0004] However, wastewater treatment sedimentation tanks often have a weak effect on wastewater treatment, requiring a lot of time to process the wastewater later, which is inconvenient for users and can no longer meet their needs. Utility Model Content

An activated carbon filter plate is fixedly installed inside the second treatment box. An ultraviolet lamp is fixedly installed near the middle of one side of the third treatment box. A photocatalytic grid plate is installed inside the third treatment box.

[0007] Furthermore, the water pump has a suction port at the bottom connected to a suction pipe, one end of which passes through the sedimentation tank and extends into its interior.

[0020] The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only descriptive and are not intended to limit the scope of protection of this utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a high-efficiency and compact wastewater treatment sedimentation tank, including a sedimentation tank 1 for settling wastewater. The sedimentation tank 1 has an internal cavity. A water pump 2 is fixedly installed near the bottom on one side of the sedimentation tank 1 for pumping wastewater. Inside the sedimentation tank 1, from top to bottom, a first treatment tank 3, a second treatment tank 4, and a third treatment tank 5 are fixedly installed. Each of the first treatment tank 3, second treatment tank 4, and third treatment tank 5 has an internal cavity, and the first treatment tank 3, second treatment tank 4, and third treatment tank 5 cooperate with each other. This system is designed to treat wastewater. The first treatment tank 3 has a fixed filter grille 6 inside, which filters out larger impurities in the wastewater. The second treatment tank 4 has a fixed activated carbon filter plate 7 inside, which adsorbs small impurities and removes odors. The third treatment tank 5 has a fixed ultraviolet lamp 8 on one side near the center, which generates ultraviolet light. The third treatment tank 5 also has a photocatalytic grille 9 inside, which reacts with the ultraviolet lamp 8 to purify harmful substances in the wastewater.

[0022] Furthermore, the water pump 2 has a suction port at the bottom connected to a suction pipe 10. One end of the suction pipe 10 passes through the sedimentation tank 1 and extends into its interior. The suction pipe 10 serves to draw water.

[0023] Furthermore, an inlet pipe 11 is connected to one side of the top of the sedimentation tank 1, and a dosing pipe 12 is connected to the other side of the top of the sedimentation tank 1. The inlet pipe 11 serves to introduce water, while the dosing pipe 12 facilitates the addition of chemicals.

[0024] Furthermore, the water pump 2 has an outlet at the top connected to an outlet pipe 13. The top of the outlet pipe 13 passes through the sedimentation tank 1 and is connected to the first treatment tank 3. The outlet pipe 13 serves to discharge water.

[0025] Furthermore, the first treatment tank 3, the second treatment tank 4, and the third treatment tank 5 are connected by a conduit. The bottom of the third treatment tank 5 is connected to an external discharge pipe, and one end of the external discharge pipe passes through the sedimentation tank 1 and extends to its outside. The external discharge pipe is used to discharge the purified water.

[0026] Furthermore, the top and bottom of the photocatalytic grid plate 9 are fixedly connected to the inner wall of the third processing box 5, wherein the photocatalytic grid plate 9 is capable of reacting with the ultraviolet lamp 8.

[0027] Furthermore, one end of the ultraviolet lamp 8 penetrates the photocatalytic grid plate 9 and is fixedly connected to the inner wall of the third processing box 5, wherein the ultraviolet lamp 8 is capable of generating ultraviolet light.

[0028] Working principle: When using this device, the user first transports wastewater to the sedimentation tank 1 through the inlet pipe 11 for sedimentation. Then, the water pump 2 is set up to pump the water flow and transport it to the interior of the first treatment tank 3. Through the setting of the filter grid 6, the wastewater entering the first treatment tank 3 can be filtered and treated, and the larger impurities contained therein can be adsorbed. Then, the water flows sequentially to the second treatment tank 4 and the third treatment tank 5. Through the setting of the activated carbon filter plate 7, the fine impurities and odors in the wastewater can be filtered out. With the ultraviolet lamp 8 and the photocatalytic grid plate 9 working together, photocatalytic oxidation-reduction reaction can be carried out to purify harmful substances in the water.

[0029] Based on the above work process, we can conclude that:

[0030] This high-efficiency, compact wastewater treatment sedimentation tank, equipped with a water pump 2, a filter grid 6, an activated carbon filter plate 7, an ultraviolet lamp 8, and a photocatalytic grid plate 9, can purify the settled wastewater during use, thereby accelerating wastewater treatment efficiency, improving wastewater treatment performance, bringing convenience to users, enhancing the practicality of the device, and meeting users' needs.
