Abstract

The invention discloses a carbon ceramic shell-core-type three-dimensional particle electrode and a preparing method thereof. The carbon ceramic shell-core-type three-dimensional particle electrode comprises a three-dimensional electrocatalytic oxidation device composed of an anode plate, an electrolytic cell, a cathode plate, a carbon ceramic shell-core-type three-dimensional particle electrode body, a peristaltic pump and a power source, the carbon ceramic shell-core-type three-dimensional particle electrode body is placed in the electrolytic cell, the two sides of the stacked carbon ceramicshell-core-type three-dimensional particle electrode body are attached to the anode plate and the cathode plate, the anode plate is connected to an a positive electrode of a power source, the cathodeplate is connected to a negative electrode of the power source, and the electrolytic cell is connected with the peristaltic pump through a guide pipe. The carbon ceramic shell-core-type three-dimensional particle electrode comprises 15-30 wt% of argil, coal powder the bulk density of which is 0.45-0.5 t / m<3> and metal salt which accounts for 1-9 wt% of the coal powder. The carbon ceramic shell-core-type three-dimensional particle electrode is high in catalytic activity and low in unit chemical oxygen demand energy dissipation, active components do not easily get lost, the service life is longeven after continuous use, the preparing process is simple, the price is low, the applicability is strong, and the carbon ceramic shell-core-type three-dimensional particle electrode is particularlysuitable for wastewater difficult to degrade biochemically.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a carbon ceramic core-shell type three-dimensional particle electrode and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, especially in the chemical industry, the waste generated has also increased, and the pollution to the environment has become increasingly serious, especially some organic pollution with high concentrations, difficult biochemical degradation, and acute or chronic toxicity. The sharp increase in the discharge of pollutants and high-concentration ammonia nitrogen wastewater will cause irreversible pollution to the environment. [0003] Traditional wastewater treatment methods mainly include: physical method, chemical method and biological method. Among them, the physical method mainly includes the adsorption method and the extraction method. The advantages of using the physical metho...

Problems solved by technology

Traditional electrode materials have large resistance and low conductivity. When used in actual wastewater treatment, the current efficiency is low, the stability is poor, the life is short, the preparation process of electrode materials is complicated and the preparation cost is high. Moreover, activated carbon materials, although the treatment effect Better, because of its expensive price and single function, it also limits its practical application in wastewater treatment. Therefore, exploring, researching and preparing a new three-dimensional electrode material is the key to solving the problem
