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.

[0025] Example 1

[0026] Please see Figures 1 to 3A split-type sewage treatment device includes a sedimentation tank 100, a treatment tank, and a storage tank 400; wherein, the sedimentation tank 100, the treatment tank, and the storage tank 400 are connected in sequence by pipelines; the sedimentation tank 100 is used for sewage sedimentation, and the sewage after sedimentation is discharged into the treatment tank for treatment, and after the sewage is treated in the treatment tank, it is discharged into the storage tank 400 for storage.

[0027] like Figure 2 As shown, the treatment tank includes a first treatment tank 200 and a second treatment tank 300; wherein, a stirring device is provided inside the first treatment tank 200, the stirring device includes a rotating shaft 500, an outer spiral blade 600, an inner spiral blade 700 and a connecting rod 800 are provided on the rotating shaft 500; the two ends of the connecting rod 800 are respectively connected to the rotating shaft 500 and the outer spiral blade 600; the inner spiral blade 700 is provided on the outer wall of the rotating shaft 500.

[0028] like Figure 3 As shown, an ultraviolet sterilization device and a driving device are installed inside the second treatment tank 300. The ultraviolet sterilization device includes a mounting frame 900, an ultraviolet lamp 110, and a cleaning ring 111. The ultraviolet lamp 110 is installed inside the mounting frame 900, and the cleaning ring 111 is sleeved on the outer wall of the ultraviolet lamp 110. The driving device drives the cleaning ring 111 to move up and down to clean the ultraviolet lamp 110.

[0029] Example 2

[0030] This embodiment is a further refinement of Embodiment 1.

[0031] Please see Figure 1-3 The modular wastewater treatment device of this invention mainly consists of a sedimentation tank 100, a treatment tank, and a storage tank 400. These components are connected sequentially via pipelines, realizing the entire process of wastewater treatment from sedimentation to storage. The treatment tank is further divided into a first treatment tank 200 and a second treatment tank 300, each with different treatment functions.

[0032] Sedimentation tank 100 is the starting point of the entire wastewater treatment process. When wastewater enters sedimentation tank 100, the impurities in the wastewater are naturally settled to the bottom of the tank by gravity. The sedimentation time can be adjusted according to the properties of the wastewater and the sedimentation effect. After the sedimentation process is completed, the clearer wastewater on the upper layer is discharged into the first treatment tank 200 through pipes.

[0033] like Figure 2As shown, a stirring device is installed in the first treatment tank 200. The device consists of a rotating shaft 500, an outer spiral blade 600, an inner spiral blade 700, and a connecting rod 800. A first mounting plate 112 is provided on the first treatment tank 200, and a first drive motor 113 is mounted on the first mounting plate 112. The output shaft of the first drive motor 113 is connected to the rotating shaft 500.

[0034] When wastewater enters the first treatment tank 200, treatment agents are added to the tank through the dosing pipe 117 on the outer wall of the tank. Then, the first drive motor 113 is started, driving the rotating shaft 500 to rotate. The outer spiral blades 600 and inner spiral blades 700 on the rotating shaft 500 rotate accordingly. During rotation, the outer spiral blades 600 cause the wastewater to flow horizontally and vertically, expanding the mixing range; the inner spiral blades 700 enhance the mixing effect of the wastewater near the rotating shaft 500. A connecting rod 800 connects the outer spiral blades 600 to the rotating shaft 500, ensuring stable rotation of the outer spiral blades 600. This coordinated operation of the inner and outer spiral blades ensures thorough mixing of the wastewater and treatment agents, improving the efficiency of wastewater treatment.

[0035] Specifically, the first treatment tank 200 can be treated with chemicals through the dosing pipe 117, such as polyaluminum chloride (PAC) or polyferric sulfate (PFS) to remove suspended solids and colloidal particles from the wastewater and form larger flocs to facilitate subsequent sedimentation.

[0036] like Figure 3 As shown, the second treatment tank 300 is equipped with an ultraviolet sterilization device and a driving device. The ultraviolet sterilization device consists of a mounting frame 900, an ultraviolet lamp 110, and a cleaning ring 111. The ultraviolet lamp 110 is installed inside the mounting frame 900, and the cleaning ring 111 is fitted around the outer wall of the ultraviolet lamp 110. The inner wall of the cleaning ring 111 is equipped with a brush.

[0037] A second mounting plate 114 is provided above the second treatment pool 300, and a drive device is fixed on the second mounting plate 114. The drive device includes a second drive motor 115 and a ball screw assembly, which consists of a screw body 116 and a screw nut. The second drive motor 115 is fixed on the second mounting plate 114, and its output shaft is connected to the screw body 116. The screw nut is installed on the screw body 116 and fixedly connected to the cleaning ring 111.

[0038] Specifically, the second treatment tank 300 can be supplemented with chemicals through the dosing pipe 117, such as sodium hypochlorite (NaClO) and chlorine (Cl2) to assist in ultraviolet sterilization and enhance the inactivation effect on bacteria and viruses, which is especially suitable for scenarios with insufficient ultraviolet radiation or fluctuating water quality.

[0039] Wastewater treated in the first treatment tank 200 enters the second treatment tank 300, where ultraviolet lamps 110 are turned on to sterilize the wastewater. During sterilization, to ensure the effectiveness of the ultraviolet lamps 110, the second drive motor 115 is periodically activated. The second drive motor 115 drives the lead screw body 116 to rotate, and the lead screw nut moves linearly along the lead screw body 116, thereby moving the cleaning ring 111 up and down along the outer wall of the ultraviolet lamp 110. The brushes on the inner wall of the cleaning ring 111 clean the outer wall of the ultraviolet lamp 110 during this movement, removing attached impurities and ensuring that ultraviolet light can fully penetrate, thus improving sterilization efficiency.

[0040] After being treated in the first treatment tank 200 and the second treatment tank 300, the wastewater enters the deep treatment tank 118 through the effluent pipe 120 of the treatment tanks. The deep treatment tank 118 further treats the wastewater, removing any remaining impurities and pollutants, so that the wastewater meets higher water quality standards.

[0041] Wastewater treated in the advanced treatment tank 118 is piped into the storage tank 400 for storage. The storage tank 400 can be configured with different capacities according to actual needs, so that the treated wastewater can be rationally utilized or discharged later.

[0042] Specifically, chemicals can be added to the advanced treatment tank 118 via the dosing pipe 117, such as a carbon source (methanol or sodium acetate). This provides a carbon source for the microorganisms during the denitrification stage, promoting the production of nitrate nitrogen (NO3). - The ammonia nitrogen (NH3-N) can be converted into nitrogen gas. Alternatively, an ammonia nitrogen removal agent (sodium hypochlorite or breakpoint chlorinator) can be added to remove residual ammonia nitrogen (NH3-N) through an oxidation reaction.

[0043] The working principle of this utility model is as follows: sewage first enters the sedimentation tank 100, and the impurities in the sewage are precipitated to the bottom of the tank by gravity, thereby achieving solid-liquid separation and providing clearer sewage for subsequent treatment.

[0044] After sedimentation, the wastewater enters the first treatment tank 200, where treatment agents are added through the dosing pipe 117. The rotation of the stirring device ensures that the wastewater and agents are thoroughly mixed, resulting in a chemical reaction that removes some of the pollutants from the wastewater.

[0045] Wastewater treated with chemicals enters the second treatment tank 300, where ultraviolet lamps 110 emit ultraviolet light to sterilize and disinfect the wastewater, killing harmful microorganisms such as bacteria and viruses. Simultaneously, a drive unit activates a cleaning ring 111 to clean the ultraviolet lamps 110, ensuring effective sterilization.

[0046] After sterilization and disinfection, the wastewater enters the deep treatment tank 118 to further remove residual impurities and pollutants from the wastewater and improve water quality.

[0047] After deep treatment, the wastewater is discharged into storage tank 400 for storage, awaiting subsequent use or discharge.
