[0034] Currently, traditional water treatment processes include several steps such as chemical reaction, stirring, sedimentation and filtration. Correspondingly, water treatment equipment is also divided into multiple independent functional units for each step. After the current step is completed, the wastewater is transported to the next unit through pipelines for the next step.

[0035] Wastewater flows through various units, which is time-consuming. Furthermore, some impurities accumulate in the pipes during this process, requiring subsequent cleaning to prevent blockages and increasing maintenance costs. Moreover, the entire water treatment system, with its multiple independent functional units, occupies a large area, demanding significant plant space and further increasing construction costs.

[0036] Therefore, there is an urgent need for a new type of water treatment device to solve the above problems and improve the efficiency and economy of water treatment.

[0037] In response, this application proposes an integrated wastewater treatment system for chemical dosing, sedimentation, and filtration. The chemical reaction, stirring, sedimentation, and filtration of wastewater are all carried out in the same tank, eliminating the need for multiple separate functional units. This avoids pipe blockage during wastewater flow and saves on subsequent maintenance costs. Moreover, the entire system occupies less space and has lower construction costs, making it more economical than traditional wastewater treatment systems.

[0038] Reference Figure 1This application discloses an integrated wastewater treatment system comprising a tank 100, a dosing device, a stirring device 200, and a filter press 300. The tank 100 serves as a container for wastewater, and the chemical reaction, stirring, sedimentation, and filtration processes in wastewater treatment all take place within this tank 100. This integrates various water treatment processes into one unit, avoiding wastewater transfer between different containers and thus reducing the system's construction and maintenance costs. The dosing device is used to add chemicals to the tank 100 to induce a chemical reaction in the wastewater. The stirring device 200 is used to stir the wastewater in the tank 100. The filter press 300 is used to filter the wastewater in the tank 100, separating the liquid wastewater from the solid sludge for subsequent separate treatment.

[0039] Specifically, the bottom of the housing 100 is provided with a sludge discharge port 110, and a valve is installed on the sludge discharge port 110 to control its opening and closing. During subsequent filtration, solid sludge can be discharged from the sludge discharge port 110.

[0040] The dosing device is connected to the housing 100 and is used to dispense drugs into the housing 100.

[0041] The stirring device 200 extends into the tank 100 to stir the sewage inside the tank 100.

[0042] Reference Figure 5 The filter press device 300 includes a filter screen box 310, which has a drain outlet 311. During subsequent filtration, liquid wastewater can be discharged out through the drain outlet 311. The filter screen box 310 can move into the housing 100, allowing liquid water in the wastewater to pass through the filter screen box 310 and be discharged through the drain outlet 311.

[0043] The filter box 310 is equipped with filter screens on each side. The filter screens isolate solid sludge from the outside, while sewage can pass through the mesh of the filter screens, thus completing the separation of sewage and sludge.

[0044] Furthermore, the bottom of the tank 100 is conical to guide the settled sludge into the sludge discharge port 110, facilitating the discharge of the sludge.

[0045] Optionally, in some embodiments, the dosage of the chemical dosing device is manually controlled by a worker who adjusts the dosage accordingly by observing the wastewater level inside the tank 100. In other embodiments, a level gauge, which is an electrical sensor, is also installed inside the tank 100 and is electrically connected to the chemical dosing device. When wastewater is added to the tank 100, the wastewater level can be detected by the level gauge, and the detection result is then fed back to the chemical dosing device. The chemical dosing device adjusts the dosage of the chemical based on the detection result of the level gauge, achieving the effect of automatically adjusting the dosage of the chemical, thereby reducing the workload of workers and improving the automation level of this integrated chemical dosing, sedimentation, and filtration wastewater treatment system.

[0046] Furthermore, referring to Figure 3 The stirring device 200 includes a motor 210 and a stirring rod 220. The first end of the stirring rod 220 is connected to the output shaft of the motor 210, so that when the motor 210 is started, its output shaft can drive the stirring rod 220 to rotate. The stirring rod 220 extends into the tank 100 to agitate the sewage.

[0047] Furthermore, the second end of the stirring rod 220 is provided with blades to agitate the wastewater. The blades are perpendicular to the stirring rod 220 and extend laterally to increase the contact area with the wastewater. As the stirring rod 220 rotates, the blades continuously collide with the wastewater, thereby agitating the wastewater and accelerating the reaction rate between the wastewater and the drug.

[0048] Specifically, the blades can be cylindrical, prismatic, or spiral, or other shapes that can agitate the wastewater to complete the mixing work, which will not be elaborated here.

[0049] Optionally, the number of stirring devices 200 can be one, two, or more, and the specific number can be increased or decreased according to the actual situation. Increasing the number of stirring devices 200 can improve stirring efficiency. In embodiments with two or more stirring devices 200, the motor 210 of each stirring device 200 can operate independently, or the stirring rod 220 in each stirring device 200 can be driven by a single motor 210 through a transmission method such as gear transmission, belt transmission, or chain transmission.

[0050] Furthermore, the filter box 310 is slidably connected to the box body 100. The filter box 310 slides into the box body 100 from the open top. The sliding connection limits the movement path of the filter box 310 and also prevents the filter box 310 from bumping into the box body 100 during its entry into the box body 100.

[0051] Specifically, in some embodiments, the inner wall of the housing 100 is provided with a sliding groove, and the outer wall of the filter box 310 is provided with a slider that can be adapted to the sliding groove. When the slider slides into the sliding groove, it can guide the sliding direction of the filter box 310. In other embodiments, a slide rail mechanism is provided between the filter box 310 and the housing 100, and the filter box 310 and the housing 100 are slidably connected through this slide rail mechanism. It is easy to understand that the filter box 310 and the housing 100 can also be configured with other forms of sliding connection, which will not be described in detail here.

[0052] Furthermore, the filter box 310 is detachably connected to the housing 100 for easy subsequent cleaning. Specifically, the inner wall of the housing 100 is provided with a groove, and the outer wall of the filter box 310 is provided with a slider that fits into the groove. The end of the groove is open, allowing the slider to disengage from the end of the groove. Thus, when it is necessary to disassemble the filter box 310, simply lift the filter box 310 upwards until the slider disengages from the end of the groove. Alternatively, the slider can be provided on the inner wall of the housing 100, and the outer wall of the filter box 310 can be provided with a groove that fits the slider, achieving the effect of both sliding and detachable connection methods.

[0053] Furthermore, the filter press 300 also includes a power unit, which is connected to and drives the filter screen box 310 to slide.

[0054] The power equipment is a device that provides a power source. In some embodiments, the power equipment is specifically a hydraulic telescopic rod, with its two ends connected to the filter screen box 310 and the housing 100, respectively. The extension and retraction of the hydraulic telescopic rod can move the filter screen box 310. In this embodiment, the power equipment is specifically a crane 320, which suspends the filter screen box 310 and can lift the filter screen box 310 to move it. It is easy to understand that other forms of power equipment can also be used to drive the filter screen box 310 to rise and fall, which will not be described in detail here.

[0055] The following describes the workflow of this integrated chemical dosing, sedimentation, and filtration wastewater treatment system:

[0056] S100. Close the sludge discharge port 110 in the tank 100 and pour the sewage to be treated into the tank 100;

[0057] S200.Reference Figure 2 The chemical is added to the tank 100 through a dosing device to react with the wastewater;

[0058] S300.Reference Figure 3 The stirring rod 220 in the stirring device 200 is inserted into the sewage, and the motor 210 is started to stir the sewage, thereby accelerating the reaction rate between the drug and the sewage.

[0059] S400.Reference Figure 4 Remove the stirring device 200 and let the wastewater in the tank 100 stand naturally, waiting for the sludge to settle to the bottom of the tank 100, in preparation for subsequent filtration.

[0060] S500.Reference Figure 5 The filter box 310 extends from top to bottom into the box 100. Liquid sewage passes through the filter box 310 and is discharged out through the drain 311. Solid sludge cannot pass through the filter box 310 and is trapped in the box 100.

[0061] S600. Open the sludge discharge port 110 in the tank 100. The sludge deposited in the tank 100 is discharged outward from the sludge discharge port 110, and the water treatment work is completed.

[0063] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
