The invention relates to a high-frequency ultra pulse three-dimensional semiconductor reactor water treatment technology which can fast decompose or thoroughly carbonize high-concentration hard-degradation organic matters, precipitate and recover heavy metal and oxidize cyanide radicals into N2 and NH3. A square-wave pulse high-frequency ultra pulse generator, a three-dimensional semiconductor electrode and a vertical packed bed type reactor are included, wherein the kernel parameters of the square-wave pulse high-frequency ultra pulse generator are as follows: the output frequency is from 50HZ to 20 KHZ, and the duty ratio d is not less than 25% and not more than 100%; the three-dimensional semiconductor electrode is formed by proportioning modified active carbon, a sintered Al2O3-TiC combination electrode and Mn / Sn / Sb loaded gamma-Al2O3 and CwO2 / Sb2O5 loaded semiconductor active carbon; and the vertical packed bed type reactor is provided with a water inlet at the bottom and a water outlet at the top. The defects of high energy consumption, large occupied area, complex operations, secondary pollution and the like in the prior art are overcome. The water treatment technology is applicable to high-salinity high-concentration hard-degradation organic waste water, and can be applied to the fields of petroleum, chemical industry, pharmacy, dye printing and dyeing, electroplating, papermaking, cultivation, garbage penetrating fluid, brackish water and the like.

Description

technical field [0001] The invention relates to a sewage treatment technology, which belongs to the field of water treatment and water pollution prevention and control, and in particular relates to a high-frequency ultra-pulse power supply technology, a three-dimensional semiconductor electrode preparation method and a proportioning technology, and a reactor structure. Background technique [0002] Water resources are one of the essential resources in the survival process of human beings and other organisms, and they are precious and limited. With the development of modern industry and human material civilization, the types and quantities of various pollutants entering the water body through various channels have increased sharply, causing serious pollution to the water environment, especially cyanide, heavy metal ions, heterocyclic compounds and high-salt Non-biochemical pollutants directly threaten human survival and health, and more and more attention has been paid to the...

Problems solved by technology

However, in conventional electrochemical reactors, the two-dimensional electrode reactor electrode has a small specific surface area and low mass transfer efficiency, resulting in poor treatment effect and serious corrosion of the plates; filling granular or debris-like materials between the plates of the traditional two-dimensional electrolyzer, Constitute a three-dimensional electrode reactor, which improves the specific surface area, current efficiency, and mass transfer efficiency of the reactor, and the treatment effect is significantly better than that of a two-dimensional electrode reactor.

In recent years, some people have done some research on three-dimensional electrode materials and reactor structures, but the catalytic materials supported by granular electrodes are easy to precipitate, and the practical applicability of the reactor is not strong. There is no reasonable rectification power supply system, resulting in high energy consumption.
