The Study of Vertical Filter with Vegetation for Village Bezděčí u Trnávky

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
