Embodiment Construction

[0021] The invention relates to a microwave plasma oxidation water treatment method and its application.

[0022] The present invention will be further described below in conjunction with embodiment.

[0023] 1. Microwave plasma oxidation water treatment method

[0024] Specific steps are as follows:

[0025] Into the industrial wastewater, the organic matter in the wastewater is adsorbed by the mixture of iron discharge body and activated carbon;

[0026] The iron discharge body is excited by microwaves to generate plasma, and the plasma oxidizes the organic matter adsorbed on the surface of the activated carbon, and at the same time, the iron discharge body, activated carbon and organic matter generate internal electrolysis to degrade the organic matter;

[0027] After oxidation and degradation, the wastewater reaches the reuse or discharge standard, and the activated carbon is regenerated and restored to activity;

[0028] Discharge the water that meets the reuse or disc...

Abstract

The present invention relates to a microwave plasma oxidation water treatment method and its application. Said invention includes the following steps: feeding industrial waste water, utilizing mixture of iron discharge body and active carbon to adsorb organics in the waste water; utilizing plasma produced by using microwave to excite iron discharge body to oxidate organics adsorbed on the surface of active carbon, at the same time internal electrolysis action produced between iron discharge body, active carbon and organics can be used for degrading organics, after the organics are oxidated and degraded, making the waste water be reached to reuse and discharge standard.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment, in particular to a microwave plasma oxidation water treatment method and its application. Background technique [0002] Environmental pollution and ecological damage 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, and the losses caused by natural disasters such as floods caused by ecological deterioration caused by environmental pollution are even more astonishing. [0003] Water pollution is a very complicated problem, with many pollution sources and varying degrees of pollution, which makes water treatment a very complicated project. To solve the problem of water pollution, we first need to understand the various sources of water pollution. The pollution sources of water bodies ar...
