Embodiment Construction

[0021] The present invention is an integrated technology of microwave plasma oxidation and enhanced active carbon regeneration to treat industrial wastewater, and the steps are as follows:

[0022] a. The mixture of iron discharge body and activated carbon adsorbs organic pollutants in industrial wastewater.

[0023] b. Under the action of internal electrolysis generated by the mixture, the adsorbed organic pollutants are oxidized.

[0024] c. In the tidal state, the microwave excites the iron discharge body to generate plasma, degrades the adsorbed organic pollutants again, and quickly regenerates the activated carbon.

[0025] d. Discharge purified industrial wastewater.

[0026] The industrial wastewater mentioned above is the sewage discharged from printing and dyeing, dyeing, papermaking and other factories, and the sewage contains high concentration of organic pollutants.

Abstract

The invention provides an industrial wastewater treatment method by internal electrolysis intensified by microwave plasma oxidation technology comprising the steps of, absorbing the organic contaminant in industrial sewage by using the mixture of irony electric discharging body and activated charcoal, oxygenizing the adsorbed organic contaminant under the internal electrolysis action produced by the mixture, the microwave energizing the irony electric discharging body to produce plasma under wet state, thus degrading the absorbed organic contaminant and regenerating activated charcoal rapidly, finally discharging the cleaned industrial sewage.

Description

technical field [0001] The invention relates to a method for microwave plasma oxidation enhanced internal electrolysis treatment of industrial waste water. Background technique [0002] Environmental pollution and ecological damage have had a huge impact on my country's economy and society, and have become important factors that endanger people's health and restrict economic and social development in some places. In 1997, my country's economic losses caused by water and air pollution alone were as high as 54 billion U.S. dollars. The losses caused by natural disasters such as floods caused by ecological deterioration caused by environmental pollution are even more alarming. Due to the characteristics of my country's large population, low per capita resources, relatively weak environmental carrying capacity, and underdeveloped economy, it is impossible to completely adopt some traditional methods commonly used by Western developed countries to solve the current complex envir...
