Problems solved by technology

[0005] Ozone has strong oxidizing properties, and its application in the disinfection process of drinking water disinfection and advanced sewage treatment has attracted more and more attention. However, low gas-liquid mass transfer efficiency and poor water solubility have become the main reasons for limiting the efficiency and economical efficiency of ozone disinfection. Reducing the diameter of ozone bubbles to increase the specific surface area of ​​ozone bubbles in water is an important means to improve the efficiency of ozone mass transfer. Therefore, the technology of using microbubble technology to improve ozone mass transfer efficiency has attracted much attention

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, in the corona plasma activation method that can improve the mass transfer efficiency of ozone microbubbles in water bodies, the air pump 2 inflates the microbubble generation chamber 4 through the "Venturi" tube 3, and passes through the filter screen 5 from the water inlet After the sewage flowing in from the pipeline 6 is mixed, it is sucked into the submersible pump 1, and under the high-speed shearing and stirring of the submersible pump impeller 7, the broken microbubbles are dissolved in the high-pressure water body in the microbubble generating chamber 4, The high-speed eruption of the throttle pipe 8 enters the microbubble pressure release pool 9, and a large number of microbubbles ejected from the microbubble pressure release pool 9 at a high speed enter the corona high-voltage electric field area 10, and after being ionized i...

Abstract

The invention relates to the technical field of sewage treatment and discloses a corona plasma activation method capable of improving the mass transfer efficiency of ozone micro bubbles in a water body. The corona plasma activation method capable of improving the mass transfer efficiency of the ozone micro bubbles in the water body is characterized by comprising the following steps: a) filling gas into the water body to obtain a mixture of the water body and the gas; b) stirring and shearing the mixture obtained in the previous step, so that bubbles are crushed, and the diameter of each bubble is reduced; c) enabling the bubbles obtained in the previous step to generate corona so as to generate the ozone micro bubbles; d) dissolving the ozone micro bubbles into the water body, removing pollutants in the water body, crushing the bubbles in a water and gas mixture before corona to reduce the diameter of each bubble, so that the gas and liquid mass transfer efficiency and the water solubility of the ozone micro bubbles generated during ozonization are improved, further the disinfection efficiency of ozone is improved, and therefore, the water quality is better changed.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a corona plasma activation method capable of improving the mass transfer efficiency of ozone microbubbles in water bodies. Background technique [0002] The organic pollution of the water environment is a global problem, which has various impacts on the human living environment. Many organic substances in the sewage are not easy to degrade, and are easy to accumulate in the environment, which in turn causes the water quality to deteriorate, become smelly and black, which is the cause of The most important source of water pollution has seriously threatened human health. The existing sewage treatment methods mainly include physical treatment methods, chemical treatment methods, adsorption treatment methods, biological treatment methods, etc. [0003] But above-mentioned sewage treatment method also has some deficiencies, such as physical treatment method, the effect to th...
