The Study of Intensification of the Constructed Treatment Wetland for the Village of Machová
Zedník, Ondřej ; Pumprlová Němcová, Miroslava (referee) ; Kriška-Dunajský, Michal (advisor)
The village Machová (650 inhabitants) operates a combined sewage system which leads to a treatment wetland. This wastewater treatment plant faces similar problems like most of treatment wetlands from the turn of the last century - it has a low efficiency of the removal of ammonia nitrogen N-NH4 + which causes a negative impact on the watercourses and the environment. The study deals with the technical modification of the operating line which would eliminate the abovementioned problems and solves the sludge treatment in treatment plant. Population growth in the village connected with the construction of sanitary sewer will cause high concentrations of pollution in the inflow. The proposed modification uses the latest scientific knowledge and proven technologies which were created by the Institute of Landscape Water Management. These technologies will secure the low effluent concentrations of monitored parameters not only today but also in case the population of the village will grow.

The Use of Recycled Building Materials for Wastewater Treatment
Zedník, Ondřej ; Pumprlová Němcová, Miroslava (referee) ; Kriška-Dunajský, Michal (advisor)
The constantly tightening wastewater treatment legislation require high-quality runoff from small-scale producers of pollution who are typically represented by small municipalities up to 500 inhabitants or decentralized parts of larger municipalities. Small municipalities are faced with high investment-intensity associated with the acquisition of new wastewater treatment plant. After several years of development, today natural technologies of wastewater treatment are in competition with mechanical-biological treatment plants. Natural technologies can even achieve better results than popular biological treatment plants. However, natural technology does not eliminate the main investment limit connected with the acquisition of wastewater treatment plant. If there was cheaper solution connected with using alternative filter materials (in our case recycled construction and demolition waste), small municipalities could take constructed wetland without large subsides. At the same time, the use of recycled construction and demolition wastes will lead to benefits in the field of sustainable urban development and replacement of non-renewable materials. Despite these benefits, recycled aggregates have never been considered as alternative filter materials for natural wastewater treatment plants. For that reason, the aim of diploma thesis is to assess the possibility of applying recycled aggregates for wastewater treatment which will include evaluation of real trial operation.

Research of the Multistage Constructed Treatment Wetlands Technology
Chaloupka, Ondřej ; Pumprlová Němcová, Miroslava (referee) ; Kriška-Dunajský, Michal (advisor)
The ways of purifying waste water produced by human society are nowadays a great deal. With the increasing pressure on sustainable construction, technology using principles close to natural processes are at the forefront. Treatment wetlands have been in use for almost 30 years and thanks mainly to developments abroad, they prove they are a suitable option for smaller producers of pollution. When designing a treatment wetland for municipalities with a larger amount of inhabitants, it is necessary to modify the proposal in order to eliminate all types of pollution. This thesis therefore compares three sewage treatment plants with a multistage filtration system. Comparing the achieved parameters will be beneficial for defining the rules for optimal design of these types of wastewater treatment plant.
