A device and method for laser cooperative ultrasonic treatment of high-salt and high-organic waste water

Abstract

The invention discloses an apparatus and a method for laser synergistic ultrasonic treatment of high salt and high organic matter wastewater. The apparatus mainly comprises laser generation devices, a laser surface controller, a shell, flow baffling plates, sound energy devices, water film areas, laser radiation areas, a water inlet pipe, a water outlet pipe and a gas discharging pipeline, wherein a plurality of reaction units are arranged in the apparatus, and each unit comprises the flow baffling plate, the sound energy device, the laser generation device, the laser radiation area and the water film area. According to the method, the structures of the organic matters in the wastewater are damaged by laser, and the organic matter removal effect is enhanced through the synergistic ultrasonic effect. According to the present invention, with the apparatus and the method, the interference of the organic components in the high salt wastewater treatment on the subsequent wastewater desalination step is reduced; and the apparatus has advantages of small occupation area, high automation degree, simple operation, rapid treatment, and no secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and energy saving, and in particular relates to a device and method for laser cooperative ultrasonic treatment of high-salt and high-organic waste water. Background technique [0002] In recent years, with the increasing shortage of water resources, sewage reuse projects have been widely implemented in our country. However, when the organic matter and salt content in the sewage are high, it cannot meet the water quality requirements of industrial production and reclaimed water reuse. Therefore, the importance of how to remove organic matter and high salinity in sewage reuse is becoming more and more prominent. [0003] In the face of increasingly stringent sewage discharge standards, the high salt content of high-salt organic wastewater has brought great obstacles to its treatment. A single treatment method has certain economic and technical problems. The deep oxidation method an...

However, when the organic matter and salt content in the sewage are high, it cannot meet the quality requirements of industrial production and reclaimed water reuse. Therefore, the importance of how to remove organic matter and high salinity in sewage reuse is becoming more and more prominent.

[0003] In the face of increasingly stringent sewage discharge standards, the high salt content of high-salt organic wastewater has brought great obstacles to its treatment, and a single treatment method has certain economic and technical problems.

The deep oxidation method and membrane separation method in the physical and chemical methods occupy a relatively small area, and there is basically no secondary pollution after treatment, but high cost and difficulty in industrialization restrict its large-scale application. The development of anti-pollution, long life, performance Stable membrane materials and components are the key to whether the membrane separation method can be applied industrially; although the biological method is currently recognized as a good method for treating high-salt organic wastewater, it occupies a large area and the treatment effect is affected by the climate
