Wastewater treatment plants for municipalities with gravitational inflow
Benešová, Irena ; Vachovec, Roman (referee) ; Hluštík, Petr (advisor)
Diploma thesis is aimed on description of wastewater treatment plant with gravitational inflow. Focus is on WWTP in the Czech Republic, particularly in the South Moravia region - in this aspect the thesis presents relevant statistics like the number of WWTP per region and the total, capacity of WWTP per region and their substance load on inflow /outflow. The recherche is also limited according to the core subject of theoretical part, which is technology of small WWTP in the category up to 2000 equivalent habitants. The experimental part presents comparsion of particular wastewater treatment plant of this category in the South Moravia region: one with gravitational inflow and one with inflow pump station. The examined wastewater treatment plant are compared according to substance load, hydraulic load and technology. Thesis is concluded with a review of the different operation parameters of the both types of WWTP.

Dlouhodobé vyhodnocení provozních parametrů ČOV Brno - Modřice
Hejmalíček, Ondřej
The thesis deals with the issue of substance load on the wastewater treatment plant from the adjacent urbanized area. The aim of the thesis is to evaluate the substance load and the amount of wastewater flowing into the WWTP, specifically the parameters of BOD5, CODCr, NH3-N, total nitrogen, total phosphorus, and the volume of inflowing wastewater. The theoretical part of the thesis first describes the basic principles of wastewater treatment, including individual treatment stages and used technologies. It also covers the possibilities of analysis and measurement of individual parameters. The practical part of the thesis presents the results of data analysis obtained from the operation of the wastewater treatment plant. These data were obtained from several decades of monitoring of the operational parameters of the plant and include both basic water characteristics and the performance of the WWTP in individual years. Based on the obtained data, changes and trends that have occurred over the years are subsequently analyzed. The development of individual parameters is analyzed, and their future prediction is carried out. Changes in short-term (days of the week), medium-term (months of the year), and long-term (years) time periods are analyzed, such as changes in substance load or inflow volume, and the impact of rainfall is also assessed. The amount of sludge, which is closely related to the substance load, is evaluated. The thesis also includes an analysis of the impact of the COVID-19 pandemic and related government measures on substance load. In conclusion, the thesis provides an overall assessment of the development of substance load on a large wastewater treatment plant and highlights the aspects that the WWTP operator must consider and how to respond to them in practice or utilize them.
