Electrochemical technology has a wide range of applications in sewage treatment and resource utilization, mainly including the following aspects:
1. Electrochemical oxidation treatment of sewage: Electrochemical oxidation is a method of oxidizing organic or inorganic matter into harmless substances. Through electrolysis reaction, the active oxygen species with high oxidation energy, such as hydroxyl radicals, hydrogen peroxide, ozone, etc., can effectively degrade organic and inorganic matter. Therefore, electrochemical oxidation technology can be applied to sewage treatment, especially for the treatment of difficult-to-degrade organic matter and high-concentration organic wastewater.
2. Electrochemical oxidation-reduction treatment of sewage: Electrochemical reduction is a method of reducing pollutants into harmless substances. Through electrolysis reaction, the reducing active species produced can react with organic matter, and the organic matter is reduced to harmless substances such as CO2 and H2O. Electrochemical oxidation-reduction technology includes electrochemical reduction, electrochemical oxidation-reduction and electrochemical reduction coupling.
3. Electrochemical oxidation treatment of heavy metal ions in wastewater: Electrochemical oxidation technology can remove heavy metal ions in wastewater. Through electrolysis reaction, the oxidizing active species produced can combine with heavy metal ions to form complexes that are easy to precipitate. Electrochemical oxidation technology is used in wastewater treatment, especially for wastewater treatment containing high concentrations of heavy metal ions.
4. Electrochemical removal of ammonia nitrogen: The electrochemical reduction reaction can reduce ammonia nitrogen to free ammonia, and the free ammonia further combines with oxygen or oxidants in the reaction solution to form nitrates or nitrites. Electrochemical removal of ammonia nitrogen can effectively reduce the concentration of nitrogen, and is particularly suitable for drinking water treatment and industrial wastewater treatment.
5. Electrochemical resource utilization: Electrochemical technology can be used for the resource utilization of valuable substances in sludge and wastewater. For example, electrochemical hydrolysis technology can oxidize organic matter into carbon dioxide, water and hydrogen, the latter of which can be used as energy; electrochemical denitrification technology can convert ammonia nitrogen into nitrates, which are further used for plant growth or fertilizers; electrochemical heavy metal leaching technology can extract valuable metals and compounds. Electrochemical resource utilization technology can realize the resource utilization of wastewater and sludge, and reduce the generation and pollution of waste.
