Problems solved by technology

[0005] However, no matter it is Fenton or electric Fenton reaction, there is a problem of slow reaction speed. The main reason is that the circulation speed between ferrous ions and ferric ions in the reaction process limits the entire Fenton reaction process.

Abstract

The invention discloses a preparation method and application of an Electro-Fenton reactor anode. The preparation method comprises the following steps: ultrasonically cleaning a stainless steel net inacetone, flushing the stainless steel net by using deionized water, then drying, cleaning in alcohol, flushing by using deioninzed water, and blow drying by using nitrogen; enabling copper hydroxide and corresponding oleic acid to react sufficiently to obtain copper oleate, introducing excessive hydrogen sulfide gas to obtain a liquid paraffin solution containing copper sulfide nano particles; winding the processed stainless steel net into a cylindrical shape, and covering the stainless steel net cylinder with a copper sulfide layer; and placing an iron bar in the stainless steel net cylinder,connecting one end of the iron bar to the stainless steel net cylinder by virtue of a conducting wire, forming a combination with the stainless steel net cylinder arranged outside and the iron bar arranged inside, wherein the combination is the Electro-Fenton reactor anode. The periphery of the stainless steel cylinder covered with the copper sulfide layer forms the degradation reaction to promote the circulation of ferrous ions and ferric ions, and the speed control step of the Fenton reaction is broken through, so that the organic matter degradation speed can be greatly increased.

Description

technical field [0001] The invention relates to the field of environmental pollution control, in particular to a preparation method and application of an anode of an electric Fenton reactor. Background technique [0002] With the development of science and technology, toxic organic pollutants from industrial and agricultural production seriously threaten the environment and human health. It is of great significance to seek a new and efficient environmental governance technology. Water contains a large number of organic pollutants, which affect the ecosystem in the form of toxicity and the reduction of dissolved oxygen in water, and endanger human health. [0003] With the rapid development of my country's national economy, high-concentration organic wastewater poses a threat to my country's precious water resources. However, using existing biological treatment methods, it is difficult to treat substances with poor biodegradability and a relative molecular mass ranging from ...
