| Research Abstract |
A biological Fenton (Bio-Fenton) process using iron compounds and aquatic plants in constructed wetlands was proposed to decompose refractory and toxic pollutants in water and wastewater. Batch and semi-continuous experimental results demonstrated that pollutants such as endocrine disrupting compounds (EDCs), pentachlorophenol (PCP) and dye could be decomposed by Bio-Fenton process. Some tropical plants possess higher endogenous hydrogen peroxide (H2O2) in comparison with temperate plants; therefore, the application of Bio-Fenton process may be more preferable in tropical than temperate regions. In addition, Bio-Fenton process was affected by iron compounds, where fine particles of magnetite were a possible iron compound with smaller stress to aquatic plants. Moreover, a procedure to identify Bio-Fenton reaction with fluorescent reagent is effective in screening appropriate iron compounds.
