The study confirms that a combination of uv irradiation and H_2O_2 addition represents a suitable option for the treatment of landfill percolation water after a first biological waste water treatment. An additional oxygen supply facility is not required. The stable purification performance is proved by following the oxygen demand, pH and temperature. The portion of BOD which is strongly increased during the photoxidation easily undergoes biodegradation in a subsequent activated sludge treatment (second biological treatment) stage. After the activated sludge treatment, the toxicity determined with luminous bacteria, green algae and dophniae and the mutagenicity determined by ames- and amu-salmonella tests and by alkaline filter elution tests with mussels in the purified water converge towards zero.
