Diamond Electrodes Enable Electrochemical Advanced Oxidation Processes for Industrial Wastewater Treatment

摘要

Rather than transporting wastewater to treatment plants, effective treatment at the generation point of the effluent minimizes the risk of contamination and also makes recycling industrial wastewater viable, dramatically improving water use efficiency. Various treatments that originated from sewage and wastewater treatment have been used to treat industrial wastewater. All of them have inherent problems that make them less than ideal processes for removal of recalcitrant compounds such as phenolic, and biocides such as ammonia; often, even in large central plants, these types of wastestreams are challenging to treat. Advanced oxidation processes (AOPs) have the ability to mineralize recalcitrant organic and inorganic contaminants in toxic and biocidal wastewater streams, via the creation of hydroxyl radicals that have the oxidation power to treat these types of effluent streams. AOPs have the advantage of being suitable for small- to medium-scale treatment systems that are straightforward to operate at the point of need.
