An improved three-dimensional three-dimensional electrode oxidation reactor

Abstract

The invention relates to an improved type three-dimensional stereoscopic electrode oxidation reactor; based on electrochemistry, a three-dimensional stereoscopic reference electrode technology is adopted, high-concentration wastewater is subjected to clean oxidation and oxidation reduction treatment, the removal rate of pollutants (such as COD, TP and TN) in the wastewater reaches more than or equal to 95%, and the technical bottleneck of high-concentration wastewater treatment is broken through. The three-dimensional stereoscopic electrode oxidation reactor can be widely applied in treatment of high-concentration high-nitrogen wastewater, such as chemical industry wastewater, landfill leachate, rare earth wet-process smelting wastewater, papermaking wastewater and the like.

Description

Technical field [0001] The invention relates to an improved three-dimensional electrode oxidation reactor. Background technique [0002] With the development of industrial society, a large amount of waste water containing organic matter will be produced in the industrial production process. If these waste water is discharged directly without treatment, it will cause very serious damage to the environment. Therefore, the treatment of organic waste water has become the current domestic and international environment. A problem to be solved in the field of protection technology. 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 transformation. At present, it has been widely studied and used in many different types of organic wastewater such as printing and dyeing, leather making, pharmaceuticals, and chemical industries. application. The three-dimensional motor is filled ...

[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
