Green Oxidation Processes for Industrial Wastewater Treatments and Biofuel Production

主讲人 : 楊昆霖副教授

To address the issues in Fenton’s reaction, we developed new  l- d catalysts which can be used in industrial wastewater treatment by using H2O2 as an oxidant. The catalysts are able to complete a redox cycle in the presence of H2O2 and generate both free radicals and high-valence  l ions. These highly reactive species are able to convert hydrocarbons, especially unsaturated organic molecules, into organic acids and carbon dioxide with high molecular efficiency. These  l- d catalysts work over a wide range of pH (3-11) and do not produce any sludge. They are soluble and can be mixed with wastewater homogenously at parts-per-million (ppm) level at neutral pH to degrade the pollutants rapidly. Because of the fast reaction rate, the hydraulic residence time of the process in a wastewater treatment plant is usually less than one hour. They can also be immobilized on solid carriers to treat the wastewater continuously in a fluidized bed. Currently, the new process has been tested in a full-scale plant in Singapore and that leads to better treatment efficiency and 50% cost-saving compared to current treatment processes.
