A three-dimensional three-dimensional electrode oxidation reactor

Abstract

The present invention relates to a three-dimensional electrode oxidation reactor, on the basis of electrochemistry, three-dimensional reference electrode technology is used for clean oxidation and oxidation-reduction treatment of high concentration wastewater, the removal rate of wastewater pollutants (COD, TP and TN) can reach more than 95%, and the technical bottleneck of high concentration wastewater can be broken. The three-dimensional electrode oxidation reactor can be widely used in treatment of high concentration high nitrogen wastewater such as chemical wastewater, landfill leachate, rare earth hydrometallurgy wastewater, papermaking wastewater and the like.

Description

technical field [0001] The invention relates to a three-dimensional electrode oxidation reactor. Background technique [0002] With the development of industrial society, a large amount of wastewater containing organic matter will be produced in the process of industrial production. If these wastewater is discharged directly without treatment, it will cause very serious harm to the environment. Therefore, the treatment of organic wastewater has become the current domestic and foreign environment. A difficult problem to be solved in the field of conservation technology. Using the chemical reaction of the electrolysis process is one of the sewage treatment methods to remove the harmful substances in the industrial sewage in the form of conversion. At present, it has been widely researched and used in many different types of organic wastewater such as printing and dyeing, tanning, pharmaceuticals, and chemicals. application. The three-dimensional motor is filled with granular...

[0003] Prior Art Yao-Hui Huang et al. applied for the U.S. Patent (Patent No. 6126838) on the method of treating wastewater by electrolytic oxidation, which mainly utilizes the method of adding chemical agents and three-dimensional fluidized electrolysis. This method has a cost due to the addition of chemical agents big problem

Chinese patent (Patent Publication No. CN1358672A) discloses a three-dimensional electrode reactor and its method for treating organic wastewater. It is mainly aimed at high-concentration organic wastewater, using electric energy to excite particle electrodes to generate strong oxidants, so as to decompose organic matter in wastewater. However, since the particle electrode needs to generate a strong oxidant, there is a problem that it oxidizes and decomposes the organic matter while oxidizing and decomposing itself, so that the life of the particle electrode is particularly short, and the cost of wastewater treatment is virtually increased.

Although these methods have their own characteristics, they also have certain limitations, or there are varying degrees of large equipment investment, high energy consumption, and high operating costs. Domestically, physicochemical and biochemical methods are mostly used, while foreign countries use chemical and biological methods as the main method. host
