Problems solved by technology

However, in the prior art, ultrasonic technology is often used alone, or wet oxidation is used alone, but the effect on wastewater treatment is not high and energy consumption increases in the process of wastewater treatment
In the process of wet oxidation, it is often not efficient

Embodiment 1

[0049] refer to figure 1 As shown, it is a schematic structural diagram of an ultrasonic wastewater treatment device provided in this embodiment, including a tank body 10 and an oxidation reactor 20 .

[0050] The very center in the tank body 10 is provided with the first sonotrode 11, and now the first sonotrode 11 is a built-in type, and the left and right sides of the first sonotrode 11 are respectively connected with connecting rods 15, and the two connecting rods 15 are connected to each other. The end is also connected with telescopic device 13, and two telescopic devices 13 are respectively arranged on the sidewall of tank body 10, can prevent like this tank body 10 deformation when first ultrasonic generator 11 vibrates, influences safety. A reverse osmosis membrane 14 is arranged above the first ultrasonic generator 11 . The waste water pipeline 12 is connected with the first ultrasonic generator 11 , the top of the tank body 10 is provided with an aqueous phase outl...

Embodiment 2

[0059] Other operation steps are the same as in Embodiment 1, the only difference is that there is no first ultrasonic generator.

Embodiment 3

[0061] Other operating steps are the same as in Example 1, the only difference is that there is no hydraulic micro-interface generator inside the oxidation reactor.

Abstract

The invention provides an ultrasonic wastewater treatment device, which comprises a tank body and an oxidation reactor, the tank body is cooperatively provided with a first ultrasonic generator used for degrading polysaccharide macromolecules, the first ultrasonic generator can be built-in or external, and the first ultrasonic generator is connected with a wastewater pipeline. A first ultrasonic generator is arranged in the tank body, a reverse osmosis membrane is arranged above the first ultrasonic generator, a water phase outlet is formed in the side wall of the top of the tank body, the water phase outlet is connected with a liquid inlet of an oxidation reactor, a hydraulic micro-interface generator for breaking and dispersing gas into microbubbles is arranged in the oxidation reactor, and the hydraulic micro-interface generator is communicated with a gas inlet pipeline; a product outlet is formed in the bottom of the oxidation reactor and is used for discharging a product. By combining the ultrasonic technology and the wet oxidation technology, the efficient and energy-saving wastewater treatment effect is achieved, polysaccharide macromolecules are degraded into micromolecular organic matter through the ultrasonic technology, and the wastewater treatment efficiency is further improved.

Description

technical field [0001] The invention belongs to the technical field of water treatment equipment, and in particular relates to an ultrasonic wastewater treatment device and method. Background technique [0002] With the continuous development in recent years, especially the development of urbanization, the speed is amazing, but the construction of related facilities required for urban development is very slow, far behind the speed of urban development, especially for the treatment of wastewater . At present, most of the waste water is treated after being concentrated. There are various treatment methods, such as pollutants and heavy metal ions in industrial waste water or humus in natural water systems. Under the joint action of ultrasonic waves and additives, severe catalytic physical Chemical reaction, converted into insoluble substances or gases, macromolecular polysaccharides in water, refractory organic pollutants, are decomposed into small molecular organic matter, co...
