The increasing concentration of nitrates in surface water and groundwater is becoming a global problem. The dissertation thesis is focused on the denitrifying bioreactors with organic fill material designed for the reduction of nitrate input from agricultural areas in the Czech Republic. A set of laboratory experiments was performed – static leaching tests and column tests, including chemical analyses of outflow water and ecotoxicological bioassays. Seven materials common in the Czech Republic, various process parameters, types and lengths of bioreactor shutdown in dry periods and the use of outflow water for irrigation were tested. The thesis deals with both denitrification efficiency and ways of reducing negative effects. An evaluation of the overall effect bioreactors is included along with a prediction regarding leaching over the following years.
