Abstract

The invention relates to an upwelling bipolar three-dimensional electrochemical reactor, and relates to a three-dimensional electrochemical reactor, which solves the problems of being low in current efficiency and poor in wastewater treatment effect in the existing three-dimensional electrochemical reactor. The upwelling bipolar three-dimensional electrochemical reactor disclosed by the invention comprises a cathode of a working electrode, an anode of the working electrode, organic glass screens and a particle electrode; the cathode is clamped between the two layers of organic glass screens, so that a cathode component is formed; the anode is clamped between the two layers of organic glass screens, so that an anode component is formed; the cathode component and the anode component are alternatively arranged at intervals along the vertical direction of the three-dimensional electrochemical reactor; a reaction unit is formed between the cathode component and the anode component adjacent to each other; the particle electrode is filled in the reaction unit; and a water outlet is formed below an overflow weir. According to the invention, the mass transfer distance of pollutants is shortened through the particle electrode, therefore, the current efficiency is increased, electrochemical reaction units are easy to increase, and finally, the removing rate of COD (Chemical Oxygen Demand) in wastewater is above 80%.

Description

technical field [0001] The invention relates to a three-dimensional electrochemical reactor. Background technique [0002] In recent years, the discharge of wastewater has shown an increasing trend. The biodegradability of toxic and harmful refractory wastewater is poor, and the composition of wastewater is becoming more and more complex. With the increasingly strict national pollution discharge indicators and the further advancement of pollution reduction work, the sewage treatment of various enterprises is facing great challenges. The current sewage treatment process can hardly meet the increasingly stringent national discharge standards. Therefore, achieving stable operation of wastewater treatment facilities and meeting discharge standards is a common problem faced by almost all enterprises. As a kind of advanced oxidation method, the electrochemical method has the characteristics of no secondary pollution, no need to add chemical reagents, mild reaction conditions, and...
