The water eutrophication is an important environmental issue in the world due to the high organic nitrogen compounds contained in the natural water resource. In Taiwan, the long-term discharge of wastewater from the electrical, agricultural, and pharmaceutical processes has made Taiwan EPA legislate against the serious situation of high ammonia content into ecological system. Biological treatment is the major technology for nitrogen removal, but it needs long reaction time and have low effective rate. Therefore, the Treatment of organic nitrogen is the major purpose. Pyridine as the heterocyclic nitrogen compound was choose as one of the pollutant, and will be treated using photo-electro Fenton process. Where 94% pyridine degradation and 70% TOC can be removed after 240 min of the reaction in the presence of 50 mg L-1 Fe2+, pHi=2, 1600 mg L-1 H2O2, CDc=4.64 A m-2. The experimental parameters included initial pH, hydrogen peroxide concentration, ferrous concentration and anion effects were studied. Furthermore the kinetics, intermediates, and reaction pathway will be evaluated.Keywords:  pyridine, photo-electro-Fenton process, kinetics, intermediate
