Zhodnocení stavu Knínického potoka z hlediska znečištění dusičnany
Caesar, Jindřich
The aim of the bachelor thesis is to monitor the stream Knínický potok in terms of water quality and nitrogen pollution. The theoretical part contains the basic facts about water and its importance to humans. Further it describes the composition and properties of water, types of water and especially water quality and pollution. There are also defined factors having the most significant impact on water quality along with the relevant le-gislation. The practical part consists of site survey and the monitoring itself, which was carried out monthly from april 2015 to march 2017. The monitoring was based on fieldwork requiring water sampling and measurement of selected parameters such as pH, conductivity, dissolved oxygen and temperature; the other parameters, nitrate and total nitrogen, were determined in the UAKE MENDELU laboratory. In the discussion part the resulsts are compared to ČSN 75 7221 and to the government regulation 401/2015 Sb., in an effective version. As a result of the work, main sources of nitrogen pollution in the stream are determined.

Zhodnocení účinnosti čistírny odpadních vod v Ivančicích
Caesar, Jindřich
The aim of this diploma thesis is to monitor the selected parameters of wastewater pollution at wastewater treatment plant in Ivančice. The theoretical part contains the basic facts about water pollution and wastewater treatment, and the relevant legislation. Fur-ther there is described the wastewater treatment plant in Ivančice. The practical part consists of the monitoring of wastewater at the affluent and effluent of the plant, which was carried out monthly from November 2018 to February 2019. That was based on sampling and measurement of selected parameters such as pH, conductivity, dissolved oxygen and temperature; the other parameters, nitrate, ammonia and total nitrogen, orthophosphates, total phosphorus and chemical oxygen demand were determined in the UAKE MENDELU laboratory. The calculated average efficiency of each parameter was over 90 %. In the discussion part the results are compared with the government regulation 401/2015 Sb., in an effective vision, with the data obtained from the wastewater treatment plant Ivančice and with some other authors.
