Zhodnocení samočistící schopnosti vodního toku Bítýška
Vítová, Kristýna
The bachelor thesis deals with the evaluation of the quality and self-cleaning ability of the Bítýška watercourse in Vysočina. The theoretical part is devoted to the water management legislation of the Czech Republic, water quality including related problems, self-cleaning ability, wetlands and monitored water quality indicators. The next part characterizes the area of interest in terms of natural conditions and hydrology. The practical part describes in detail the collection of water samples, measurement of water quality indicators in the field and laboratory determination of chemical water analysis. The work concludes with an evaluation of the results obtained according to the relevant legislation and discussion. The results of laboratory analysis have demonstrated that the self-cleaning ability of watercourses was exhibited only for half of the monitored period and cannot be unequivocally confirmed. The findings revealed high concentrations of nitrate nitrogen, total phosphorus and chemical oxygen demand caused especially by draining under-cleaned water from root wastewater treatment plant into the watercourse.

Study of micropolutant removal at the root sewage treatment plant
Pešková, Karolína ; Zlámalová Gargošová, Helena (referee) ; Mravcová, Ludmila (advisor)
This bachelor thesis focuses in the theoretical part on explaining the concept of a root sewage treatment plant. There is also a more detailed description of these root sewage treatment plants functioning. Attention is paid to the phases of root sewage treatment plants, their basic functional principles, vegetation, selected pharmaceuticals and methods of their determination. In the experimental part, samples of wastewater from the root sewage treatment plant in Dražovice in Vyškov District, were processed. Eight selected drugs (atenolol, azithromycin, diclofenac, ibuprofen, carbamazepine, clarithromycin, sulfamethoxazole and trimethoprim) were monitored in wastewater. These drugs were isolated from wastewater by solid phase extraction and then a method for identification and quantification was used – liquid chromatography with mass detection.

Comparison of mechanical and biological wastewater treatment plants in terms of financial costs and environmental impact
Winkler, Ondřej ; Výskala, Miloslav (referee) ; Aigel, Petr (advisor)
The aim of this bachelor thesis is to analyse and compare the operating costs and quality of water discharged at mechanical-biological and root wastewater treatment plants. In the first part, the bachelor thesis deals with theoretical knowledge in the field of wastewater treatment. There is legislation related to WWTPs, types, quantities, and transport of wastewater, it also describes the process and technology of water treatment and, finally, the management of waste generated during treatment and its treatment. The following chapters are devoted to economic indicators of wastewater treatment plants as well as pollution indicators. This part forms the transition between the theoretical and practical part of the bachelor thesis. We will learn here what are the costs of operating the treatment plant and how these costs will be reflected in the calculation of sewerage. We will also learn here which pollution indicators are measured as part of the quality of wastewater discharged from the WWTP. In the following part, the bachelor's thesis deals with the analysis and comparison of the already mentioned costs of operation and quality of discharged water at different types of wastewater treatment plants. The analysis was performed at four root and six mechanical-biological wastewater treatment plants in a total of four districts. The conclusion of the bachelor thesis belongs to the global comparison within the Czech Republic and the evaluation of the goals of the bachelor thesis.

The Study of Intensification of the Constructed Treatment Wetland for the Village of Machová
Zedník, Ondřej ; Pumprlová Němcová, Miroslava (referee) ; Kriška-Dunajský, Michal (advisor)
The village Machová (650 inhabitants) operates a combined sewage system which leads to a treatment wetland. This wastewater treatment plant faces similar problems like most of treatment wetlands from the turn of the last century - it has a low efficiency of the removal of ammonia nitrogen N-NH4 + which causes a negative impact on the watercourses and the environment. The study deals with the technical modification of the operating line which would eliminate the abovementioned problems and solves the sludge treatment in treatment plant. Population growth in the village connected with the construction of sanitary sewer will cause high concentrations of pollution in the inflow. The proposed modification uses the latest scientific knowledge and proven technologies which were created by the Institute of Landscape Water Management. These technologies will secure the low effluent concentrations of monitored parameters not only today but also in case the population of the village will grow.
