Description

Technical Field

[0001] The utility model relates to the field of sewage disinfection equipment, in particular to an ozone catalytic oxidation water treatment device. Background Art

[0002] Ozone catalytic oxidation technology is an efficient wastewater deep treatment technology and has been a hot application in the field of wastewater treatment in recent years. Compared with ozone as a single oxidant, the hydroxyl radicals formed by ozone under the action of a catalyst have a higher reaction rate with organic matter and stronger oxidizing properties, and can oxidize almost all organic matter. The catalyst can catalyze ozone to directly oxidize organic matter in water into CO2 and H2O, or oxidize and decompose large molecular organic matter into small molecules, making it easier to degrade. The oxidized water produced during the ozone catalytic treatment process still contains certain pollutants. In order to ensure that the sewage meets the discharge standards, it needs to be further purified.

[0003] Sodium hypochlorite is widely used as a disinfectant in sewage treatment. Sodium hypochlorite can provide hypochlorous acid as a powerful oxidant and disinfectant. In sewage treatment, it can effectively kill bacteria, viruses and other microorganisms, thereby achieving the effect of disinfection and sterilization. Hypochlorous acid can destroy the cell wall and nucleic acid structure of bacteria, thereby achieving a bactericidal effect.

[0004] In the existing device for treating oxidized water with sodium hypochlorite, after the oxidized water is treated with ozone catalysis, some small impurities still remain inside. During the purification process using sodium hypochlorite, the small impurities are easily unable to be cleaned and are easily accumulated inside the device, or discharged again with the water, thereby reducing the purification effect. In addition, as the oxidized water treatment work continues, the impurities accumulated inside the device are easily mixed with the water that subsequently enters the device and is discharged, thereby affecting the cleaning effect of the subsequent water.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1 , Figure 2 and Figure 3 An ozone catalytic oxidation water treatment device shown includes a treatment pool 1 and a plurality of disinfection nozzles 3 facing the inner cavity of the treatment pool 1. The plurality of disinfection nozzles 3 can spray sodium hypochlorite disinfectant. A rotatable filter screen 4 is arranged in the inner cavity of the treatment pool 1. The filter screen 4 is an arc-shaped structure. In a natural state, the filter screen 4 is symmetrically distributed in the inner cavity of the treatment pool 1. When oxidized water and sodium hypochlorite fall to the surface of the filter screen 4, small particles of impurities mixed in the water are retained on the surface of the filter screen 4. The filter screen 4 has a decontamination effect on them, preventing impurities from accumulating at the bottom of the inner cavity of the treatment pool 1. When the impurities retained on the surface of the filter screen 4 accumulate to a certain thickness, the impurities slide along the surface of the filter screen 4 under the action of gravity and the impact of the oxidized water.

[0024] Receiving grooves 7 are arranged in a semicircular distribution on both sides and at the lower position of the filter screen 4. The receiving grooves 7 can receive some impurities that slide down along the surface of the filter screen 4. At the same time, the filter screen 4 is in a rotating state, and the top of the receiving groove 7 is fixedly connected to one end of the filter screen 4. When the filter screen 4 rotates, the surface of the filter screen 4 slides and contacts the elastic scraper 8. Some impurities on the surface of the filter screen 4 can be scraped off by the elastic scraper 8 and transferred to the inside of the receiving groove 7, which can maintain the smoothness of the surface of the filter screen 4, avoid the clogging of the surface of the filter screen 4 due to the accumulation of impurities, and ensure the smoothness of the circulation of oxidized water and sodium hypochlorite disinfectant.

[0025] The surface of the receiving tank 7 is provided with a plurality of channels for water to fall, and the oxidized water and sodium hypochlorite disinfectant can pass smoothly without affecting the discharge of the oxidized water after disinfection. The front and rear ends of the receiving tank 7 are both mounted on the inner wall of the treatment tank 1 through the positioning frame 9, which can maintain the stability of the receiving tank 7, and the filter screen 4 and the receiving tank 7 can be cleaned regularly to transfer impurities and dirt.

[0026] like Figure 4 , Figure 5 As shown, the front and rear ends of the filter 4 are both installed with arc-shaped drive frames 5, which have a reinforcing effect on the filter 4 and can maintain the balance of the filter 4, thereby improving the stability of the filter 4 under long-term working conditions.

When the drive motor 10 is in operation, it can provide an operating force for the drive shaft 6 to achieve the purpose of driving the drive shaft 6, the drive frame 5 and the filter 4 to rotate synchronously.

[0027] like Figure 4 , Figure 5 As shown, the outer surface of the driving shaft 6 is provided with a plurality of stirring wheels 61 along the direction of the filter screen 4, and the stirring wheels 61 are located directly below the filter screen 4. During the rotation of the driving shaft 6, the stirring wheels 61 can be driven to stir the water inside the treatment pool 1, accelerate the fusion of the oxidized water and the sodium hypochlorite disinfectant, and improve the disinfection efficiency.

[0028] like Figure 2 As shown, a closed cover 11 is arranged above the treatment pool 1, and the cover 11 can maintain the sealing of the treatment pool 1 and reduce the odor of the treatment pool 1. A frame 12 is installed outside the treatment pool 1. The frame 12 can maintain the stability of the treatment pool 1.

[0029] like Figure 1As shown, multiple rows of liquid distribution pipes 2 are arranged above the cover body 11, and the liquid distribution pipes 2 are connected to the disinfection nozzles 3 to form a liquid supply channel for the sodium hypochlorite disinfectant to fall into the inner cavity of the treatment tank 1, thereby ensuring that the sodium hypochlorite disinfectant can smoothly flow into the inner cavity of the treatment tank 1.

[0030] like Figure 1 , Figure 2 As shown, the side wall of the treatment tank 1 is provided with a water inlet 13 and a water outlet 14 which are connected to the inner cavity thereof from top to bottom, and the oxidized water can enter the treatment tank 1 through the water inlet 13, and after being disinfected inside the treatment tank 1, it is discharged through the water outlet 14. It is worth mentioning that the water inlet 13 is located above the filter screen 4 to ensure that the oxidized water can fully contact the filter screen 4, and the water outlet 14 is located below the receiving tank 7 to ensure that the oxidized water after disinfection can be fully discharged.
