Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to ozone sterilization equipment for sewage treatment. Background Art

[0002] Ozone disinfection refers to water treatment technology that uses ozone as a disinfectant. Ozone is a strong oxidant. After dissolving in water, it directly or indirectly oxidizes inorganic and organic matter in the water using a large number of hydroxyl free radicals and new ecological oxygen generated in the reaction, and enters the cells of bacteria to oxidize the intracellular organic matter, thereby achieving the purpose of sterilization and purification of water quality. Compared with chlorination disinfection, ozone disinfectant is small, fast-acting, and has better disinfection effect. At the same time, it can improve the taste and appearance of water.

[0003] Traditional sewage treatment equipment discharges ozone directly into the treatment tank, and sterilizes the wastewater by contacting it with ozone. However, in actual use, the density of sewage is greater than that of ozone, so ozone is always located above the sewage and cannot have good contact with the sewage. The sterilization effect is very poor, and there are certain deficiencies in its use. For this reason, we propose an ozone sterilization equipment for sewage treatment. Utility Model Content

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Reference Figure 1-3, an ozone sterilization device for sewage treatment, comprising a bottom plate 1, a treatment tank 2 is installed on the top of the bottom plate 1, a water inlet pipe 3 and a water outlet pipe 4 are installed on both sides of the treatment tank 2, an oxygenation mechanism 5 is installed on the side of the treatment tank 2, the oxygenation mechanism 5 is inserted into the treatment tank 2, the oxygenation mechanism 5 includes an ozone generator 51 fixed to the side of the treatment tank 2, an oxygen supply tank 52 is installed on the side of the ozone generator 51, a connecting pipe 53 is installed at the bottom of the ozone generator 51, the connecting pipe 53 is inserted into the treatment tank 2 and connected to an aeration plate 54, a fixing ring 6 is installed on the treatment tank 2, a cover plate 7 is installed on the fixing ring 6 by bolts, a filtering mechanism 8 and a pressure relief valve 9 are installed on the cover plate 7, and the filtering mechanism 8 includes a connecting rod 81 fixed to the bottom of the cover plate 7 and a motor 87 installed on the top of the cover plate 7 A filter box 82 is fixed at the bottom of the connecting rod 81, and a filter plate 83 is rotatably connected to the top of the filter box 82. A first rotating shaft 84 is fixed to the bottom of the filter plate 83, and a stirring rod 85 is fixedly sleeved on the first rotating shaft 84. The first rotating shaft 84 passes through the bottom of the filter box 82 and is connected to a first stirring blade 86. A second rotating shaft 88 is fixed to the top of the filter plate 83, and a second stirring blade 89 is installed on the side of the second rotating shaft 88. The output shaft of the motor 87 is connected to the second rotating shaft 88 through a spline. The interior of the filter box 82 is filled with filter material. By setting an oxygenating mechanism, ozone is introduced into the interior of the treatment tank using the oxygenating mechanism. The aeration disk distributes ozone inside the treatment tank. In conjunction with the filtering mechanism, the contact area between ozone and sewage is increased while filtering the sewage. The device has a simple structure and can effectively improve the ozone sterilization effect.

[0018] When in use, the device is connected to a power source, and the motor 87 is started. The output shaft of the motor 87 drives the second rotating shaft 88 to rotate, and the second rotating shaft 88 drives the second stirring blade 89 and the filter plate 83 to rotate. The rate 83 drives the stirring rod 85 and the first stirring blade 86 to rotate through the first rotating shaft 84. The stirring rod 85 stirs the filter material in the filter box 82, and the sewage is passed into the treatment tank 2 through the water inlet pipe 3. The sewage enters the treatment tank 2 and is filtered by the filter box 82, the filter plate 83 and the filter material. Then the ozone generator 51 is started, and the ozone generator 51 will supply oxygen through the ozone generator 51. The oxygen entering through the feeding pipe 52 is processed into ozone, and is passed into the treatment tank 2 through the connecting pipe 53 and the aeration plate 54. The aeration plate 54 makes the ozone evenly distributed inside the treatment tank 2. Since the density of ozone is less than the density of sewage, the ozone floats to the top of the treatment tank 2, and is intercepted by the filter box 82, the filter plate 83 and the filter material in the process, thereby increasing the contact time between the ozone and the sewage. The first stirring blade 86 and the second stirring blade 89 are provided to stir the sewage and the ozone, thereby increasing the contact area between the ozone and the sewage. The device has a simple structure and is very convenient to use.

[0019] To sum up, compared with the prior art, the utility model provides an oxygenating mechanism, which is used to introduce ozone into the interior of the treatment tank. The aeration plate distributes the ozone inside the treatment tank, and cooperates with the filtering mechanism to increase the contact area between ozone and sewage while filtering the sewage. The device has a simple structure and can effectively improve the sterilization effect of ozone.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
