Abstract

The present invention belongs to the application of low temperature plasma technology in the field of controlling environmental pollution, and is especially high voltage pulse discharge apparatus and process to generate high chemically active particle degrading organic pollutant in water. The technological scheme includes using sand core to make the solution distributed homogeneously in the lower layer inside the reactor, applying high voltage pulse across The high voltage electrode in the liquid phase and the earth electrode in the gas phase, acting the liquid phase generated low temperature plasma and the gas phase generated ozone directly on the organic pollutant under the action of high strength electric field, using the baffling metal net in the solution to raise ozone utilization rate, adding active carbon fiber and ferrous ion into solution to raise the organic pollutant treating effect.

Description

technical field [0001] The invention belongs to the application of low-temperature plasma technology in the field of environmental pollution control, and relates to a method and a device for degrading organic pollutants in water by using high-activity chemical particles generated by high-voltage pulse discharge. Background technique [0002] At present, the pharmaceutical, printing and dyeing, chemical, petroleum and other industries have produced a large amount of industrial wastewater. This type of wastewater has a large discharge volume, complex water quality, high content of toxic and harmful pollutants, and a wide distribution range, which poses new challenges to traditional water treatment processes. In the past 30 years, some new water treatment technologies have emerged for these refractory wastewater. Among them, high-voltage pulse discharge has attracted widespread attention due to the diversity of energy release in the electron transfer process and its application ...
