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.

French systems technology for natural wastewater treatment in small municipalities
Tůmová, Tereza ; Němcová, Miroslava Pumprlová (referee) ; Kriška-Dunajský, Michal (advisor)
The bachelor thesis deals with the "French systems" technology, or French solution for natural wastewater treatment. The system receives raw wastewater (without a pre-settling tank) directly into the first filtration stage, the basic principle of which is to process sludge and wastewater in one step, so there is no need to build settling tanks. It is a natural treatment plant which, thanks to its characteristics, could help small municipalities which, for economic reasons, cannot afford expensive mechanical-biological wastewater treatment plants. The thesis includes a clear description of the procedure for sizing the individual facilities according to foreign literature, and a literature search will be carried out within the theoretical introduction to French systems, including operational experience and results from abroad. The theoretical possibilities of using materials other than natural ones for the creation of the filter cartridge of vertical filters will be described. The practical part of the thesis deals with the specific design of a natural wastewater treatment plant using the French system of wastewater treatment for a part of the village of Jablonové in Slovakia. The condition of the design is to meet the emission limits (within the framework of the current legislation) and to ensure the necessary efficiency of wastewater treatment, especially in the pollution indicators BOD5, COD, TSS, TKN.

Effluent-free treatment plant technology for small wastewater producers
Škarpa, Pavel ; Němcová, Miroslava Pumprlová (referee) ; Kriška-Dunajský, Michal (advisor)
The work aims to find new ways to dispose of wastewater. The theoretical part covers the currently known procedures for the discharge of treated wastewater into surface or groundwater, as well as the balancing of wastewater after previous accumulation. Furthermore, the theoretical part summarises the legislation of the Czech Republic concerning wastewater disposal. The measurement part deals with a new potential option, a sump with upstream water treatment. If the treatment is carried out on the principle of natural wastewater treatment, the volume of water can be reduced by evapotranspiration. Therefore, the aim of this work is to determine the realistic evapotranspiration of a vertical filter, to find a design methodology for a vertical filter to achieve optimal evapotranspiration and a suitable technological arrangement. Another objective is to use long-term air temperature records available from the Czech Hydrometeorological Institute database. The average daily evapotranspiration measured on the laboratory model reached a value of 4.5 mm/day in September 2021. In March 2022 it reached almost 2 mm/day. The equations for determining the potential evapotranspiration applied in the calculation part of the work achieved the highest agreement of 67.5% with the evapotranspiration measured on the laboratory model and will therefore be further developed to achieve much higher reliability of the calculation.
