The thesis also lists and describes methods for removing pesticides from water. Furthermore, the content of the theoretical part touches upon the topic of the Modřice wastewater treatment plant, primarily describing its treatment process. The practical part of the thesis involves laboratory research on the oxygen consumption rate of microorganisms in activated sludge in the presence of pesticides toxic to these organisms.
