Description

Technical Field

[0001] This utility model discloses an oxidation tank, belonging to the technical field of sewage treatment equipment, specifically relating to an ultrasonic ozone synergistic oxidation tank for sewage treatment. Background Technology

[0002] The combination of ultrasound and ozone oxidation technology can fully disperse and dissolve ozone, reducing the amount of ozone required while enhancing its oxidation capacity. The cavitation effect of ultrasound and its resulting physicochemical reactions can strengthen ozone decomposition, generating a large number of free radicals. These free radicals can more effectively decompose pollutants in wastewater.

[0003] The cavitation effect of ultrasound in high-temperature, high-pressure ozone cavitation bubbles can directly decompose pollutants in wastewater. Ozone, as a strong oxidant, can react with organic matter in water to generate hydroxyl radicals. These radicals have a strong oxidizing effect, capable of oxidizing recalcitrant organic matter into carbon dioxide and water, or oxidizing toxic and harmful substances into harmless substances.

[0004] However, traditional ultrasonic ozone oxidation tanks are integrated and operate within a large oxidation tank. This method is inefficient, resulting in a slow ozone dissolution rate, which requires more time to reach the desired ozone concentration. Utility Model Content

[0005] Purpose of the utility model: To provide an ultrasonic ozone synergistic oxidation tank for sewage treatment, which solves the problems mentioned above.

[0006] Technical solution: A wastewater treatment ultrasonic ozone synergistic oxidation tank, comprising:

[0011] The exhaust pipe has its input end connected to the output end of the exhaust gas destruction device.

[0012] In a further embodiment, the oxidation tank group is provided in several groups, and each group of oxidation tank groups is connected to the ozone inlet pipe and the exhaust gas outlet pipe, and each group is provided with an exhaust gas destruction device and a connecting pipe inside.

[0013] In a further embodiment, the first oxidation tank and the second oxidation tank are provided with an inlet branch pipe at one end and an outlet branch pipe at the other end.

[0016] In a further embodiment, the first oxidation tank and the second oxidation tank are provided with a breather valve at the top, and the first oxidation tank and the second oxidation tank are provided with a plurality of partition plates, the partition plates being provided with ventilation holes.

[0017] Beneficial effects: The ultrasonic ozone synergistic oxidation tank of this invention can break ozone bubbles into microbubbles through the crushing effect of ultrasound, which greatly improves the ozone dissolution rate and increases the ozone concentration per unit time.

[0026] An ultrasonic ozone-co-oxidation tank for wastewater treatment includes: an oxidation tank group, wherein the oxidation tank group consists of a first oxidation tank 1 and a second oxidation tank 2;

[0027] Ozone inlet pipe 3 has an input end connected to the ozone preparation room and an output end connected to the first oxidation tank 1 and the second oxidation tank 2 of the oxidation tank group.

[0031] In one embodiment, such as Figures 1 to 4As shown, the oxidation tank group is provided in several groups, and each group of oxidation tanks is connected to the ozone inlet pipe 3 and the exhaust gas outlet pipe 6, and each group is provided with an exhaust gas destruction device 4 and a connecting pipe 5 inside.

[0032] In one embodiment, such as Figures 1 to 4 As shown, the first oxidation tank 1 and the second oxidation tank 2 are provided with an inlet branch pipe 7 at one end and an outlet branch pipe 8 at the other end.

[0033] In one embodiment, such as Figures 1 to 4 As shown, both the first oxidation tank 1 and the second oxidation tank 2 are equipped with ozone branch pipes 9 and ozone pipes 10 at their inner bottoms; the input end of the ozone branch pipe 9 is connected to the ozone inlet pipe 3 and the output end is connected to the ozone pipe 10.
