Problems solved by technology

[0003] Because organic matter needs to consume oxygen during its decomposition process, it is called an oxygen-consuming pollutant, and the oxidation reaction requires oxygen. The current electrochemical oxidation treatment technology does not do a good job of controlling the dissolution rate of oxygen in sewage. Directly lead to unsatisfactory treatment effect of organic wastewater

Abstract

The invention discloses an organic wastewater treatment device based on an electrochemical oxidation technology and a method thereof, and belongs to the field of sewage treatment. The organic wastewater treatment device based on an electrochemical oxidation technology comprises a treatment pool, box bodies are arranged on the two sides of the treatment tank, the upper end of each box body is communicated with a water inlet pipe, a bubble generator is mounted at the bottom end of each box body, and an ultrasonic instrument is mounted at the upper end of each box body. Ultrasonic waves and an electrochemical method can be combined to improve the degradation effect of organic matters. External air is pumped into sewage by utilizing mechanical rotating force to generate bubbles so as to increase the content of oxygen in the sewage, extra energy does not need to be consumed in the process, energy is saved, and consumption is reduced. Microorganisms are cultured in release balls in advance to enhance degradation of organic matter, and the activity of the microorganisms is improved through weak current. In addition, the capillary phenomenon of capillary tubes can provide attachment pointsfor bubbles, therefore, the retention time in sewage is prolonged, and the utilization rate of oxygen is increased.

Description

technical field [0001] The invention relates to the field of sewage treatment, more specifically, to an organic wastewater treatment device and method based on electrochemical oxidation technology. Background technique [0002] Organic wastewater is wastewater mainly composed of organic pollutants. Organic wastewater is likely to cause eutrophication of water quality and is relatively harmful. At present, electrochemical oxidation is mainly used to treat organic wastewater. Electrochemical oxidation is a solution or organic matter placed in an electrolytic cell. Suspension, through direct current, captures electrons on the anode to oxidize organic matter or first oxidizes low-valent metals to high-valent metal ions, and then the high-valent metal ions oxidize organic matter. [0003] Because organic matter needs to consume oxygen during its decomposition process, it is called an oxygen-consuming pollutant, and the oxidation reaction requires oxygen. The current electrochemic...
