Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and specifically relates to a high-efficiency three-dimensional water distribution sewage treatment device. Background Art

[0002] People will discharge a large amount of wastewater in their production and life activities. If these wastewaters are not treated, they will have adverse effects on the environment. Therefore, there are many sewage treatment equipment that can effectively treat urban domestic sewage, industrial wastewater, etc., and prevent sewage and pollutants from directly flowing into waters. It is of great significance to improve the ecological environment, enhance the quality of the city and promote economic development.

[0003] The amount of sewage discharged from the factory is relatively large. When treating these sewage, the sewage treatment system needs to homogenize and treat them separately. The system that disperses and homogenizes a large amount of sewage is called a water distribution system. There are various existing water distribution systems, such as large-scale long-row water distribution systems that are arranged side by side and staggered up and down, or stepped water distribution systems. However, these existing water distribution systems have complex structures, and the water flowing out of the main pipe has a large impact on the branch pipe, which will be damaged or corroded over time and cause leakage. On the other hand, in many cases of existing water distribution systems, sewage is exposed to the outside. Under the sunlight, more algae may grow in the sewage or some dirt in the sewage will block the drainage outlet of the water distribution system, and the odor emitted will also cause environmental pollution. Therefore, it is necessary to propose a new type of water distribution sewage treatment system to overcome the above-mentioned defects. Utility Model Content

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0025] As shown in the figure, the utility model describes an efficient three-dimensional water distribution sewage treatment device, including a treatment tank 1, a trumpet-shaped water inlet 2 is provided just above the treatment tank 1, a water inlet pipe 3 is connected below the water inlet 2, a water distribution plate 4 is provided above the inside of the treatment tank 1, an arc-shaped protrusion 5 is formed in the middle of the water distribution plate, the lower end of the water inlet pipe 3 is directly opposite to the arc-shaped protrusion 5, the periphery of the arc-shaped protrusion 5 is an arc-shaped groove 6, the periphery of the arc-shaped groove 6 is connected to the inner wall of the treatment tank 1, and a plurality of water outlets 7 are provided at the arc-shaped protrusion 5.

[0026] The three-dimensional water distribution sewage treatment device described in the utility model consists of an upper water distribution system, an intermediate treatment system, and a bottom water outlet and slag discharge system. When working, the sewage enters the treatment tank 1 from the water inlet pipe 3, first falls on the arc-shaped protrusion 5 in the middle of the water distribution plate, and then scatters to the side along the arc-shaped protrusion 5, and finally most of it remains in the arc-shaped groove 6. Since the size of the downspout 1 7 is smaller than the size of the downspout 2 8, the sewage falls evenly from the downspout 1 7 and the downspout 2 8, increasing the reaction area with the bacterial flora. Combined with the use of the agitator, the treatment effect is better, the speed is faster, the cost is lower, and the practicability is wider, thereby achieving the purpose of saving resources, protecting the environment, and reducing construction costs.

[0027] A filter screen 9 is provided on the surface of the first and second drain ports 7 and 8, which can retain debris in the arc-shaped groove 6 so that the staff can clean it or replace the filter screen at the manhole 10, and the tank will not be blocked.

[0028] The utility model provides a slag discharge device at the bottom of the processing tank 1 to discharge the slag after processing, so that the slag will not be discharged randomly, which is energy-saving and environmentally friendly.

[0029] The utility model provides a polytetrafluoroethylene anti-corrosion layer inside the processing tank 1, which can extend the service life of the processing tank 1 and prevent the inner wall from being corroded.

[0030] In order to prevent the sewage falling from the water inlet pipe 3 from causing damage to the water distribution plate 4 due to its strong impact force, the utility model provides a water blocking plate 18 inside the water inlet pipe 3 to reduce the impact force of the water flow and protect the water distribution plate 4.

[0031] On the other hand, the utility model has a buffer layer 19 above the arc-shaped protrusion 5 in the middle of the water distribution plate. The buffer layer is made of hard plastic material and its shape matches the arc-shaped protrusion 5, which can further reduce the impact of water flow and prevent the water distribution plate 4 from deformation.

The outer edge of the water distribution plate 4 described in the utility model is connected to the connecting block 21 on the inner wall of the treatment tank through a connecting strip 20. When replacing, it only needs to be disassembled and assembled with screws, which is convenient and practical.

[0033] The agitator 12 of the utility model includes a motor 22 and a stirring rod 23. The stirring rod extends into the treatment tank and is connected to the motor at the bottom of the treatment tank. A plurality of stirring blades 24 are arranged on the stirring rod. When working, the agitator 12 runs simultaneously, which can speed up the sewage treatment speed.

For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
