Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a device for automatically controlling ozone addition according to water volume in a water plant. Background Art

[0002] In recent years, with the increase of micro-pollutants in water bodies and the improvement of effluent standards, ozone oxidation technology has been widely used; in the deep treatment of tap water, ozone oxidation is used in combination with activated carbon adsorption to remove trace organic matter; in the deep treatment of sewage, ozone oxidation is used in combination with biological treatment technology to remove refractory organic matter, which is suitable for sewage plants with high effluent standards:

[0003] A large amount of ozone needs to be added during the ozone oxidation reaction. Since the ozone addition control is a multi-factor interference process, it is nonlinear and has hysteresis. At the same time, due to the fluctuations in the amount and quality of incoming water, as well as the existence of factors such as mass transfer and incomplete reaction, excessive ozone is usually added based on production and operation experience to ensure that the effluent water quality meets the standards. This experience-based addition method is bound to cause ozone waste and increase the operating costs of the water plant. At the same time, excessive ozone addition will also increase the potential pollution risk of water bodies and the pollution of the atmospheric environment. Utility Model Content

A plurality of through holes 22 are provided on the surface of the mixing plate 21. A motor 4 is coaxially fixedly installed on one end of one of the rotating rods 2 close to the synchronous wheel 3. By setting the motor 4, it is convenient to drive the rotating rod 2 to rotate.

[0020] The two rotating rods 2 are fixedly sleeved with a synchronous wheel 3 at one end away from the mixing plate 21. The two synchronous wheels 3 are connected by a synchronous belt 31. By setting the synchronous wheel 3 and the synchronous belt 31, the two rotating rods 2 can be rotated by the synchronous wheel 3 and the synchronous belt 31, thereby reducing the use of the driving source.

Finally, the electric regulating valve 14 is controlled to adjust the total ozone dosage, and the ozone dosage of the three gas distribution pipes 11 is controlled by three solenoid valves 16; the rotating rod 2 is driven to drive the mixing plate 21 to rotate, and the mixing plate 21 stirs the water to be treated in the ozone contact tank 1 so that it can fully contact with the ozone, thereby improving the ozone treatment efficiency. The through hole 22 is set to reduce the resistance encountered by the mixing plate 21 during rotation and speed up the rotation.
