[0002] In the environmental protection field, wastewater treatment is a crucial link, which is of great significance to protect water resources and maintain ecological balance. Traditional wastewater treatment methods often involve multiple treatment units, such as conditioning tanks, reaction tanks, sedimentation tanks, and filtration tanks. These units usually need to be built separately and connected by pipelines, which not only occupies a large area, but also has complex operation and maintenance and high cost.

[0003] In recent years, with the continuous progress of wastewater treatment technology, integrated wastewater treatment equipment has gradually attracted attention. This type of equipment integrates multiple treatment units into one, optimizes design and efficient process, and realizes the compactness, efficiency and automation of wastewater treatment. However, traditional integrated wastewater treatment equipment often has the problem of uneven mixing effect during stirring and mixing. This is mainly due to the unreasonable design of stirring blades or stirring method, which leads to insufficient contact and mixing of materials during stirring, thereby affecting the subsequent treatment effect.

[0004] In the filtration and separation link, traditional equipment also faces the challenge of limited sedimentation efficiency. Due to the unreasonable design of filtration structure or improper operation, the sediment cannot be effectively separated, thereby affecting the effluent water quality.

DETAILED DESCRIPTION

[0031] The integrated SBR reactor for wastewater treatment of the present utility model will be described in more detail below in conjunction with the accompanying drawings and through specific embodiments.

[0032] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] This embodiment discloses an integrated SBR reactor for wastewater treatment, which has the advantages of integrating mixing, filtration, sedimentation, and aeration into one unit, aiming to improve the overall efficiency of wastewater treatment and the quality of effluent. (Refer to...) Figure 1 , Figure 2 The system mainly includes a filter tank 1, filter bars 5, fixed around the inner top wall of the filter tank 1 in an L-shape with evenly distributed grooves on the top for guiding water flow and initial filtration, a mixing tank 6 connected to one side of the filter tank 1 and controlled by a solenoid valve for mixing wastewater and chemicals, and an outlet 2 at the top of the filter tank 1 for discharging treated clean water. It also includes a drain outlet 3 located on the inner bottom wall of the filter tank 1 and connected to the bottom of a filter funnel 8 for discharging sludge and residual wastewater, an aeration pipe 4 installed inside the filter tank 1 for aeration of the wastewater, and a filter funnel 8 located on the inner bottom wall of the filter tank 1 for collecting and discharging sediment.

[0034] The filter strips 5 are arranged in a ring along the inner top wall of the filter tank 1. Their unique L-shaped design and the evenly distributed grooves on the top work together to effectively guide the water flow to be evenly distributed and initially filter out larger particulate impurities, laying a good foundation for subsequent treatment.

[0035] The mixing tank 6, a crucial step in mixing wastewater and chemicals, uses a solenoid valve to precisely control the water flow, ensuring thorough mixing of the wastewater and appropriate amounts of chemicals within the tank, thus accelerating the decomposition and transformation of pollutants. The mixed wastewater then re-enters the filter tank 1 for further filtration by the filter strips 5.

[0036] The outlet 2 at the top of the filter tank 1 is located in an area where the water flow is relatively clear, ensuring that the discharged water meets high standards. The drain outlet 3, located on the inner bottom wall, is closely connected to the filter funnel 8. The filter funnel 8, through its shape design, effectively collects and concentrates the sediment, and finally discharges the sludge and residual wastewater from the system through the drain outlet 3, avoiding secondary pollution to the environment.

[0037] In addition, during the aeration process of aeration pipe 4, oxygen is evenly released into the sewage through the aeration pipe, which increases the dissolved oxygen content in the sewage, promotes the growth and metabolic activities of microorganisms, and thus accelerates the degradation of organic matter and the sedimentation of suspended solids.

[0038] The fusion tank is provided with a stirring part, including a transmission shaft and a rotating shaft driven by a driving motor, and stirring blades fixed on the rotating shaft, and stable and efficient stirring is realized through the cooperation of the gear and the limiting ring. Figure 1 、 Figures 3-4 The stirring part 7 is arranged inside the fusion tank 6. The stirring part 7 includes a driving motor 701 and a limiting ring 704, both of which are fixed to one side of the fusion tank 6 through a connecting plate 705, and the output shaft of the driving motor 701 is connected to a transmission shaft 706. The transmission shaft 706 is provided with a limiting sleeve ring 7010 at the bottom, and the limiting sleeve ring 7010 is fixed with a bearing 708 on one side. The rotating shaft 709 is fixed with a transmission gear 707 at the top, which rotates in cooperation with the tooth groove opened on the inner side of the limiting ring 704. The outer surface of the rotating shaft 709 is fixed with the inner ring of the bearing 708. The limiting ring 704 is sleeved on the transmission shaft 706, cooperates with the limiting sleeve ring 7010 and the transmission gear 707, and ensures the stable rotation of the rotating shaft 709. The bottom of the rotating shaft 709 is fixed with stirring blades 702. The stirring blades 702 are provided with through holes 703 for improving stirring efficiency and reducing rotation resistance.

[0039] The driving motor 701 serves as a power source and is stably installed on one side of the fusion tank 6 through the connecting plate 705. The output shaft of the driving motor 701 is directly connected to the transmission shaft 706, realizing efficient transmission of power. The specially designed limiting sleeve ring 7010 at the bottom of the transmission shaft 706 not only enhances the structural strength, but also serves as a guide and limiting device for the rotation of the rotating shaft 709.

[0040] The top of the rotating shaft 709 is fixed with the transmission gear 707, which closely cooperates with the tooth groove opened on the inner side of the limiting ring 704, ensuring the stability and accuracy of the rotating shaft during transmission. At the same time, the outer surface of the rotating shaft 709 is closely fixed with the inner ring of the bearing 708, further improving the smoothness and durability of the rotation. The limiting ring 704 is sleeved on the outside of the transmission shaft 706, and cooperates with the limiting sleeve ring 7010 and the transmission gear 707 to form a stable rotating support system, effectively preventing shaking and deviation during rotation.

[0041] The stirring blades 702, as the execution component of the stirring part, are fixed to the bottom of the rotating shaft 709 and are designed with through holes 703. These through holes not only help to reduce the rotation resistance during stirring, but also can form a small vortex effect during stirring, further improving the uniformity of the mixed liquid and the stirring efficiency.

[0042] The design of the rotating shaft 709 rotating along the transmission shaft 706 enables the stirring blades 702 to obtain greater torque during rotation, thereby generating stronger stirring force. This powerful stirring force can ensure that the sewage is fully dispersed and mixed with the medicine water during stirring.

[0043] The working principle of the integrated SBR reactor for wastewater treatment is as follows: when the device is used, sewage is first added to the inside of the fusion box 6, then the driving motor 701 is started, the output end of the driving motor 701 drives the transmission shaft 706 to rotate, the transmission shaft 706 drives the limiting sleeve ring 7010 to rotate, the limiting sleeve ring 7010 drives the bearing 708 and the rotating shaft 709 to rotate along the transmission shaft 706, the transmission gear 707 on the rotating shaft 709 rotates in the limiting ring 704, the tooth groove in the limiting ring 704 limits the transmission gear 707, so that the transmission gear 707 rotates along the tooth groove, thereby driving the rotating shaft 709 to rotate, the rotating shaft 709 drives the stirring blade 702 to rotate to stir the sewage, accelerate the fusion of the sewage and the medicine water, pass through the hole 703, reduce the pressure of the stirring blade 702 rotation, and can more carefully stir the sewage;

[0044] The electromagnetic valve is opened, the sewage is discharged into the inside of the filter tank 1 after stirring is finished, the clean water after precipitation flows into the inside of the filter strip 5 through the tooth groove on the filter strip 5, and flows into the water outlet 2 through the filter strip 5 and is discharged, the sludge and the sewage after precipitation are discharged through the blow-off port 3 at the bottom of the filter funnel 8, and the aeration pipe 4 is connected with an external device used for aeration to perform aeration treatment on the sewage in the filter tank 1.
