Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment, in particular to a continuous activated carbon tower for sewage treatment. Background Art
[0002] Wastewater treatment is a matter of concern all over the world, especially the treatment of domestic sewage. In the process of treatment, it will not affect the surrounding environment. The sewage must be treated to meet the standards and some small debris and odors in the sewage must be treated first. Activated carbon layer adsorption is often used. Activated carbon will not release other toxic and harmful substances during the sewage treatment process, and will not affect the surrounding environment. In addition, the cost of activated carbon treatment of sewage is low and the process is simple.
[0003] When activated carbon is used to treat sewage, the sewage flows through the activated carbon. There are many tiny pores on the surface of the activated carbon, and the odor in the sewage is adsorbed through the tiny pores. During the treatment process, the single-stage treatment device cannot have a good continuous treatment effect on the sewage. Secondly, the activated carbon needs to be replaced after a period of use. The activated carbon that first contacts the sewage needs to be replaced regularly. Finally, the treatment device does not have a filtering device before the activated carbon adsorption. Some larger debris can easily enter the activated carbon adsorption area, reducing the treatment effect. Therefore, in response to the above problems, a continuous activated carbon tower for sewage treatment is proposed. Utility Model Content

[0026] The filtering aperture of the filter screen 7 is smaller than the hole diameter of the perforated plate 6; the connection between the discharge pipe 9 and the primary tower 1 is located on the side with a lower height of the filter screen 7; one end of the connecting pipe 14 located inside the secondary tower 16 is fixedly connected to the fixing rod 3, and one end of the fixing rod 3 is fixedly connected to the hemispherical baffle 4; one end of the drainage pipe 17 located inside the secondary tower 16 is fixedly connected to the cage-shaped filter box 15.
[0027] Working process: This device is an activated carbon tower for continuous sewage treatment, which has a first-level tower 1 and a second-level tower 16. The bottom of the first-level tower 1 is fixedly connected to an inlet pipe 2 and a sewage pipe 5. The top of the outer side of the water inlet pipe 2 is fixedly connected to a fixed rod 3. The outer side of the fixed rod 3 is fixedly connected to a hemispherical baffle 4. The perforated plate 6 is inclined in the first-level tower 1. The filter screen 7 is at the top of the perforated plate 6. The activated carbon layer 8 is filled above the filter screen 7. A discharge pipe 9 is provided on the outside of the first-level tower 1. A plugging cover 10 is threadedly connected to one end of the discharge pipe 9. A rubber pad 11 is located on the plugging cover 10. The interior of the first tower 1 plays a sealing role. The tops of the first and second towers 16 are fixedly connected with a feed pipe 12. The blocking plate 13 is connected to the top of the feed pipe 12 by bolts. The top of the first tower 1 is fixed with a connecting pipe 14. The end of the connecting pipe 14 away from the first tower 1 is connected to the bottom of the second tower 16. The internal structure of the second tower 16 is exactly the same as that of the first tower 1. A drain pipe 17 is fixedly connected to the top of the second tower 16. When the equipment needs to be used to treat sewage, an appropriate amount of granular active agent is first added to the first tower 1 and the second tower 16 through the feed pipe 12. The activated carbon layer 8 is above the filter screen 7. The sewage enters the primary tower 1 from the water inlet pipe 2. Under the action of the hemispherical baffle 4, the sewage will not directly impact the perforated plate 6 and the filter screen 7. After passing through the perforated plate 6 and the filter screen 7, the sewage reaches the activated carbon layer 8. After being filtered and adsorbed by the activated carbon layer 8, it enters the cage filter box 15 and then enters the secondary tower 16 through the connecting pipe 14. Secondary treatment is carried out in the secondary tower 16 to achieve the purpose of continuous filtration and adsorption. Finally, the treated sewage is discharged from the drain pipe 17. When replacing, stop the entry of sewage, open the blocking cover 10, and the granular activated carbon slides from the top of the inclined filter screen 7 to the discharge pipe 9, and then is discharged from the primary tower 1 or the secondary tower 16. After enough activated carbon is discharged, close the blocking cover 10, open the blocking plate 13, and add an appropriate amount of activated carbon into the treatment tower through the feed pipe 12 to ensure that the working capacity of the activated carbon layer 8 for treating sewage will not be reduced. The debris filtered by the perforated plate 6 and the filter screen 7 accumulates at the bottom end of the inner part of the primary tower 1. When it needs to be discharged, open the drain pipe 5, and the debris is discharged from the drain pipe 5 to the primary tower 1.
