DETAILED DESCRIPTION

[0023] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.

[0024] Embodiment: A harmless centralized treatment station, such as Figure 1 , Figure 3 and Figure 4 As shown, it includes a water inlet cylinder 1, a water inlet pipe 2, a connecting pipe I3, a treatment cylinder 4, an air cylinder 5, a vent pipe 6, a one-way valve I61, a discharge valve 7, a connecting pipe II11, a one-way valve III12, a valve 13, an aeration disc 14, a filter plate 15 and an exhaust gas treatment component. The top of the water inlet cylinder 1 is connected to the water inlet pipe 2, the treatment cylinder 4 is connected to the water inlet cylinder 1 by a connecting pipe I3, the air cylinder 5 is connected to the treatment cylinder 4 by a vent pipe 6, and the exhaust gas treatment component is connected to the exhaust gas treatment component. A one-way valve I61 is provided on the gas pipe 6, and the one-way valve I61 only allows the gas in the treatment cylinder 4 to flow into the gas cylinder 5. A discharge valve 7 is installed at the bottom of the treatment cylinder 4. The lower part of the side wall of the treatment cylinder 4 and the gas cylinder 5 is connected with a connecting pipe II11. A one-way valve III12 is installed on the end of the connecting pipe II11 located inside the treatment cylinder 4. The one-way valve III12 can prevent the liquid from flowing into the connecting pipe II11. The connecting pipe II11 is also provided with a valve 13. A multi-layer aeration disk 14 is installed inside the treatment cylinder 4. The disk body of the aeration disk 14 is provided with evenly distributed small holes. When the gas at the connecting pipe II 11 flows from bottom to top through the holes of the aeration disk 14, a large number of small bubbles are generated when contacting the sewage. During the rising process of the bubbles, they will fully contact with the wastewater flowing downward, increase the gas exchange area, so that the waste gas dissolved in the wastewater is brought out of the water surface, thereby exposing the waste gas in the wastewater. After the waste gas in the sewage is fully exploded, the one-way valve III 12 is temporarily closed to stop the upward ventilation of the connecting pipe II 11, so that the sewage can continue to flow downward through the aeration disk 14 for subsequent filtering operations. A multi-layer filter plate 15 is installed inside the treatment cylinder 4, and each layer of the filter plate 15 is located between two adjacent aeration disks 14. A waste gas treatment component is provided on the air cylinder 5, and the waste gas treatment component is used to treat the waste gas discharged into the air cylinder 5 by the ventilation pipe 6.

[0025] like Figure 3 and Figure 4As shown, the aeration plate 14 is inverted on the inner wall of the treatment tube 4 with its opening facing downward. A membrane with dense pores is also provided on the inner wall of the aeration plate 14. After the air source is provided by the connecting pipe II 11, the pores of the membrane on the aeration plate 14 are opened, and the fine holes on the aeration plate 14 can be used to aerate the sewage more fully.

[0026] like Figure 2 and Figure 3 As shown, the exhaust gas treatment component includes an intake pipe 8, a one-way valve II9 and an air filter plate 16. The lower part of the side wall of the air cylinder 5 is connected with the intake pipe 8, and the intake pipe 8 is provided with a one-way valve II9. The one-way valve II9 only allows gas to flow into the air cylinder 5 from the outside. The air cylinder 5 is connected with an exhaust pipe, and an air filter plate 16 is installed on the upper part of the inner wall of the air cylinder 5. The air filter plate 16 can be specifically made of activated carbon. The air filter plate 16 is used to filter out harmful substances, particles or odors in the exhaust gas introduced into the air cylinder 5, so as to achieve the effect of filtering the exhaust gas.

[0027] like Figure 2 and Figure 3 As shown, a fan 10 is also provided in the air intake pipe 8, and the fan 10 is rotatably installed inside the air intake pipe 8 through a bracket. The fan 10 can speed up the air intake rate in the air cylinder 5, thereby speeding up the efficiency of filtering the exhaust gas by the air filter plate 16; the water inlet cylinder 1 is provided with a mounting ring 17, a rotating shaft 18 and a screen 19, and a mounting ring 17 is sealed and installed at the top air inlet of the water inlet cylinder 1, and a rotating shaft 18 is rotatably installed on the mounting ring 17, and a screen 19 is installed at the lower end of the rotating shaft 18, and the screen 19 is used for centralized filtering of solid waste in the waste liquid flowing down.

[0028] like Figure 2 and Figure 5 As shown, a turbofan 20 is also provided in the water inlet cylinder 1. The turbofan 20 is installed at the upper end of the rotating shaft 18. The turbofan 20 is located inside the mounting ring 17. The turbofan 20 can convert the power of the waste liquid flowing down into a driving force for rotation. The turbofan 20 drives the screen 19 to rotate through the rotating shaft 18, so that the screen 19 can rotate to filter the waste liquid.

[0029] like Figure 1 , Figure 2 and Figure 6 As shown, an opening is provided on the side wall of the water inlet cylinder 1, and a door panel 101 is rotatably installed on the opening. A sealing gasket is provided between the door panel 101 and the opening, and rotating and opening the door panel 101 can facilitate cleaning of solid waste filtered on the screen 19; the screen 19 is a conical mesh frame, and the screen 19 is installed on the rotating shaft 18 with the opening facing upward, and a plurality of guide baffles are provided on the inner wall of the screen 19.

[0030] When the waste liquid needs to be harmlessly treated, when the waste liquid is passed into the water inlet cylinder 1 through the water inlet pipe 2, the continuously flowing waste liquid will drive the turbine fan 20 to rotate when it flows through it. At this time, the rotating turbine fan 20 will drive the screen 19 to rotate through the rotating shaft 18, so that the waste liquid can be filtered by the rotating screen 19 after falling into the water inlet cylinder 1, thereby allowing the solid waste mixed in the waste liquid to be filtered out by the screen 19. After the solid waste is filtered, the waste liquid will flow into the treatment cylinder 4 through the connecting pipe Ⅰ3. At this time, by starting the fan 10 and blowing air into the air cylinder 5, it enters the air cylinder. Under the action of the one-way valve Ⅰ 61, the gas in 5 cannot enter the treatment tube 4 from the ventilation pipe 6, but enters the treatment tube 4 at the connecting pipe Ⅱ 11 of the valve 13, so that the gas discharged from the connecting pipe Ⅱ 11 can flow from bottom to top through the multi-layer aeration disk 14. When the waste liquid entering the treatment tube 4 flows downward through the multi-layer aeration disk 14, the upward-flowing airflow will collide with the waste liquid on the aeration disk 14. Under the action of the fine holes on the aeration disk 14, a large number of fine bubbles are generated when the waste liquid covers the aeration disk 14. After the bubbles are fully in contact with the waste water, The gas dissolved in the water is brought out to achieve the effect of aerating the waste gas. At the same time, the upward airflow can bring the waste gas aerated on the aeration plate 14 upward into the ventilation pipe 6. When the sewage fully explodes the waste gas on the aeration plate 14, the connecting pipe Ⅱ11 is temporarily closed through the one-way valve Ⅲ12 to continue ventilation, so that the fully aerated sewage can smoothly pass through the aeration plate 14 and flow down. Therefore, by intermittently controlling the ventilation effect of the connecting pipe Ⅱ11, the sewage can pass through the multiple layers of aeration plates 14 in turn and be aerated, and the aerated waste gas can enter the air cylinder 5 through the ventilation pipe 6. Under the action of the fan 10 continuously drawing in gas, the exhaust gas in the air cylinder 5 floats up, and the harmful substances, particles and odors mixed in the floating exhaust gas will be filtered and absorbed by the air filter plate 16. Finally, the gas that has been filtered and meets the standards will be safely discharged from the exhaust port of the air cylinder 5. The waste liquid that has been aerated multiple times by the multi-layer aeration disk 14 in the treatment cylinder 4 will flow through the multi-layer filter plate 15. Finally, the waste liquid that has been fully filtered by the multi-layer filter plate 15 will enter the discharge valve 7, and then the discharge valve 7 will be opened to discharge the waste liquid that has been filtered and meet the standards and safely collected for subsequent environmental protection treatment.
