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.

Pumprlová Němcová, Miroslava ; Hynánková,, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
This thesis deals with the composting of sewage sludge and wetland plants biomass wasted from treatment wetlands. The introductory part of this thesis is the literature research of technical information from authors who deal with the topic of sewage sludge and composting. The introductory part provides basic information about the issue compost and composting. The theoretical part of this thesis is followed by the practical part. The practical part is divided into two research projects. The first one is focuses on methodology of building compost from waste materials such as sewage sludge and wetland plants biomass. The second one deals with the testing and usability soil moisture sensors mostly used to monitoring of the compost humidity. The research work is focused on soil moisture sensors calibration. The measurement results will be statistically analyzed and used for further work with soil sensors of compost. Results of the work can serve materials for operators and owners of treatment wetlands. This solution would lead to a significant reduction of operating costs when is considered sludge management.

Monitoring and evaluation the first year of operation of the vertical flow filter in constructed wetland
Vláčil, Lukáš ; Kriška-Dunajský, Michal (referee) ; Pumprlová Němcová, Miroslava (advisor)
This Bachelor’s thesis evaluates the one-year operation of a new type of vertical filter bed in the constructed wetland in Dražovice. This evaluation will be used to compare the efficiency of treatment – ammonia nitrogen removal – in the Dražovice constructed wetland before reconstruction (the installation of the vertical filter) and after the reconstruction. The introductory part deals with the theoretical research summarizing expert information and learnings, in order to provide insight into the issue of constructed wetlands and vertical filters in particular. Individual technological installations are described and the operating principle of constructed wetland technology is explained. The practical part of the thesis describes and evaluates the treatment efficiency of the vertical filter installed in the Dražovice constructed wetland in 2016. The results evaluation focuses on two indicators: N-NH4+ and CODCr in the period between January 2017 and May 2018.

Technology to increase hydraulic conductivity of constructed wetlands
Pobořil, Jan ; Hynánková,, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
Constructed wetlands are one of alternative solution wastewater treatment. Compared to conventional wastewater plants have many advantages. For example it´s technology saving construction, low operating costs, cleavability diluted wastewater and little or no need for electrical power. There are many publications dealing with Natural Ways wastewater treatment or even constructed wetlands. I decided to look for a thesis on one of the key processes – clogging bed media. The thesis is focused on ways to prevent clogging of bed media, mitigate the consequences and technology to increase hydraulic conductivity of constructed wetlands. The main test method is improving drainage parameters using pulsed filling and emptying of the bed media. This method is a very effective way to achieve quality requirements for effluent water from the treatment plant. Another test method is based on the injection of air into the media bed and sludge extraction using a specially modified industrial vacuum cleaner or pump.

Possibilities of technical implementation of intensification the constructed treatment wetland
Suchánek, Pavel ; Kriška-Dunajský, Michal (referee) ; Pumprlová Němcová, Miroslava (advisor)
The Bachelors thesis is a study of three variants of solution of reconstruction and intensification of specific constructed wetland. Request for reconstruction of existing cleaner facility arose from an observer, who demanded increasing of cleaning efficiency because of expected changes on sewer. The introductory part deals with a theoretical summary of expert knowledge and information, which are responsible for familiarization with problematics of constructed wetland. Just the information about reconstructions of others constructed wetlands could be essential for solving this thesis. Based on the results of the progress and effectiveness of the proposed changes, it is possible to be inspired for further solutions. Practical part of thesis is a separate study, within which were proposed three variants of solution. Variants differ in economic and technical difficulty and are linked to each other. The first one is the least difficult option and serves only for maintain temporary state. The second variant includes complex reconstruction of the object using a vertical filter and ensures effective removal of observed pollution parameters (Suspended solids, COD, BOD, N-NH4+). The third option, economically and technologically the most demanding, should moreover chemically precipitate phosphorus. For clarity of the proposal were all variants compiled in 3D model. The aim of thesis was to elaborate several variants of solution of reconstruction and intensification of existing constructed wetland Biskoupky so that the operator can choose the one that suits him at most, taking into account the investment aspect.

The Issue of Vertical Filters with Vegetation for Municipalities up to 500 PE
Brychtová, Veronika ; Přecechtěl, Karel (referee) ; Kriška-Dunajský, Michal (advisor)
Thesis consist of two parts theoretic one focus on wastewater, wastewater treatment and practical part which focus on the most appropriate option how to treat wastewater in Pyšel village. In this location was in the past purchased a study of variant solutions. From the economical/investment/the most appropriate point of view was chosen vertical wetland. Nowadays vertical wetlands are very suitable for small municipalities under 500 equivalent inhabitants because of the low demand for electricity and the presence of operators is not necessary. This technology became unpopular in Czech Republic after few incorrectly designed vertical wetlands. These problems cause insufficient cleaning ability especially about ammonia, phosphorus or other mostly oxygen parameters. Flawless design and optimized service of vertical wetland can achieve better results than biologically – mechanical waste water treatment plant. Design for Pyšel village is based on research processed by Institute of landscape water management (Kotěnice and Dražovice). Part of the design are also sludge fields, which were build for minimalized financial expenses for Pyšel village inhabitants.
