The Study of Vertical Filter with Vegetation for Village Bezděčí u Trnávky
Kacetlová, Klára ; Přecechtěl, Karel (referee) ; Kriška-Dunajský, Michal (advisor)
This bachelor thesis follows up modern vertical flow constructed wetland for wastewater treatment for Bezděčí u Trnávky village in the Czech republic. This village has 250 habitants. Technology of construted wetlands is alternative method of wastewater treatment. There are a lot of problems with this technology in the Czech republic. These problems are results from wrong design or improper operation. It causes insufficient cleaning efficiency. The worst cleaning efficiency is in removing ammonia nitrogen. To right functioning of constructed wetland is necessary change the approach to design of the constructed wetland. The thesis is based on results of the right designed constructed wetland in Dražovice village and on working technology in Austria as well. All thesis is devided into two parts. The first part consists of literature research, which summarises basic knowledge related to constructed wetland of wastewater treatment. The second part includes two options of designing constructed wetland. The first one consists of two wastewater treatment elements and the second one includes three elements. The main aim of this technology is not only to eliminate the required pollution by decree law, but also to remove nitrogen and phosphorus. The wastewater sludge treatment is based on innovated reed-bed system with wetland vegetation.

The study of modern treatment wetland for the Hlína village
Komendová, Denisa ; Pumprlová Němcová, Miroslava (referee) ; Kriška-Dunajský, Michal (advisor)
This thesis deals with the design of a modern constructed wetland for wastewater treatment for the Hlína village, Brno – venkov district (320 PE). Constructed wetlands are an alternative technology for wastewater treatment. In Czech Republic this technology often encounters a lot of problems arising from wrong design or improper operation. This problems cause insufficient cleaning efficiency, mainly in removing ammonia nitrogen. It is necessary to design the constructed wetland differently, thus make them a competitive against other waste-water treatment technologies, and ensure a higher cleaning efficiency mainly of ammonia nitrogen. The thesis is based on findings from exploratory and operating objects as results from cooperation with Institute of landscape water management. There are a new solutions and designs applied in this project, including several utility models. The first part consists of literature research, which summarizes basic knowledge on constructed wetlands for wastewater treatment. The result of the second part of the thesis is designed sewage treatment system, which comprises several serial and parallel connected sewage treatment elements. The aim is to not only eliminate the required pollution by decree law, but also to remove nitrogen and phosphorus. The part of the design is also a wastewater sludge treatment, based on innovated reed-bed systems with wetland vegetation.
