Plasma sewage treatment device and treatment method thereof

Abstract

The invention provides a plasma sewage treatment device and a treatment method thereof. The device comprises a shell (1), a reaction cylinder (3) is arranged in the shell, a plasma generation electrode (2) is arranged between the shell (1) and the reaction cylinder (3), a water outlet pipe (16) is arranged on the side, close to the upper end, of the reaction cylinder (3), the lower end of the reaction cylinder (3) is connected with a water inlet pipe (12), a gas supply pipe (9) is arranged on the side, close to the lower end, of the reaction cylinder (3), the section of the reaction cylinder (3) is polygonal, and a plurality of aeration stopping blocks (17) are arranged in the polygonal reaction cylinder (3) from top to bottom. The device has the advantages that the plasma discharge distance can be adjusted according to sewage conditions and outflow water, plasma can be formed in different gas-liquid mixed phases, and low-temperature plasma treatment efficiency can be effectively improved.

Description

technical field [0001] The invention relates to a plasma sewage treatment device and a treatment method thereof, belonging to the technical field of sewage treatment. Background technique [0002] With the continuous development of industrial economy, environmental problems have become increasingly prominent and become the focus of people's attention. The pollution of the water environment brought by various industrial productions is becoming more and more serious, and the components in the sewage are becoming more and more complex, which brings great challenges to the sewage treatment technology. The increasing shortage of water resources and the country's gradual emphasis on environmental issues have also made the environmental protection department put forward higher requirements for sewage treatment. With the continuous improvement of people's awareness and the emphasis on the overall protection of the environment, the secondary pollution generated in the process of sew...

AI Technical Summary

Problems solved by technology

[0004] The existing plasma reaction is generally directly aerated in the reactor through the aeration tube, the aeration uniformity is poor, the aeration type is single, and the aeration type cannot be changed according to different types of sewage and effluent requirements, and the low temperature cannot be further improved. Plasma treatment efficiency and discharge distance; in addition, pollutants in the sewage are also easy to block the aeration pipe, and the pressure loss of the aeration pipe is large, and the power consumption of the air supply pipe is large
