Abstract:

The bachelor's thesis deals with the energy assessment of the wastewater treatment process and the possibilities of increasing its energy efficiency and self-sufficiency in view of the new requirements of European legislation. The theoretical part of the thesis summarizes the current requirements for urban wastewater treatment in the Czech Republic in connection with Directive (EU) 2024/3019 of the European Parliament and of the Council. It introduces requirements for energy neutrality and self-sufficiency and also tightens the limits for the discharge of treated wastewater. Furthermore, energy-intensive processes, methods of assessing the energy efficiency of treatment plants and reference values for specific consumption resulting from benchmark studies are described.
The practical part of the thesis focuses on the analysis of the operation of the wastewater treatment plant in the city of Adamov. It includes an assessment of the hydraulic and material load, an evaluation of the energy balance, an assessment of the overall technological state of the treatment plant and the identification of the most energy-intensive equipment. Finally, suitable measures are proposed to improve the energy intensity of the treatment plant and the energy efficiency of the treatment processes.

Process of defence

V úvodu obhajoby studentka přednesla hlavní teze své bakalářské práce. Byly přečteny posudky vedoucího práce a oponenta. Studentka zodpověděla připomínky obsažené v posudcích. Následně proběhla diskuze k bakalářské práci, při níž členové komise položili následující dotazy: 1) Jaká je dnes průměrná hodnota rozpuštěného kyslíku v nitrifikační nádrži? 2) Je na ČOV SBR nebo oddělená nitrifikace a denitrifikace? Areace je spouštěná časově? 3) Jakou byste doporučila koncentraci rozpuštěného kyslíku v kyslíkové zóně provozovateli? 4) Čím bylo způsobeno, že hodnota spotřeby na EO za rok klesla od roku 2020 do roku 2024 z 84 na 49 kWh/EO/rok? 5) Kolik si myslíte, že procentuálně tvoří balastní vody v kanalizaci? 6) Bude provozovatel implementovat některé věci, které jste navrhla? Studentka reagovala výborně.
