Organic wastewater is characterized by its diverse origins, high toxicity, and resistance to biodegradation, posing significant threats to human health, animal life, and the natural environment. The UV/H2O2 photochemical technology is an advanced oxidation technology which utilizes light energy to activate hydrogen peroxide, generating highly reactive hydroxyl radicals.
