It is a method that uses the principle of electrochemistry to treat wastewater, by applying an electric current to the surface of the electrode, a redox reaction occurs in the process of contact between the electrode and the wastewater, so as to remove or degrade the organic matter and pollutants in the wastewater. The following is the detailed application process of microelectrolysis in laboratory wastewater treatment:
System design and preparation
Design and build a microelectrolysis setup, typically including an electrolyzer, anode and cathode electrodes, a power supply, and a control system.
Ensure that the electrolyzer is the right size and capacity to treat wastewater, and that the electrode surface area and spacing are able to achieve the desired reaction results.
Select the electrolyte and electrode material
Select the appropriate electrolyte (usually a salt solution) to increase the conductivity of the wastewater and enhance the electrolysis effect.
Choose the right electrode material, including iron, ferroalloy, aluminum, titanium and other metal materials with good corrosion resistance.
Adjust the operating parameters
Determine the appropriate current density and electrolysis time, parameters that affect the degradation rate of organic matter in wastewater.
By adjusting parameters such as current density, electrolysis time, and electrode spacing, the wastewater treatment effect is optimized.
Wastewater treatment process
The wastewater to be treated is passed into the electrolyzer and brought into contact with the anode and cathode.
By applying a suitable electric current, the ions in the electrolyte undergo a redox reaction on the electrode surface.
During the electrolysis process, the organic matter in the wastewater may be oxidized and decomposed, and gases (e.g. oxygen, hydrogen) and precipitates may also be produced.
Post-treatment water quality monitoring and treatment
After the treatment is completed, the treated water quality is monitored and analyzed to ensure the degradation and removal of organic substances and pollutants.
The micro-electrolyzed water is subjected to subsequent treatment steps such as filtration, sedimentation, neutralization, etc., to remove residual solid particles or other products.
Equipment Maintenance & Catalysts**
Regularly clean and maintain the electrolyzer and electrodes to ensure the normal operation of the equipment.
If necessary, try to treat or treat the resulting precipitate to facilitate the use of catalysts or other valuable substances.
As an electrochemical treatment technology, microelectrolysis can effectively degrade organic matter and pollutants in the laboratory environment, but it needs to be reasonably designed and adjusted according to the characteristics of wastewater and experimental conditions to improve the efficiency and effectiveness of wastewater treatment.
