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.

Monitoring of water quality in the river Stropnice
Petrlíková, Kateřina ; Tesařová, Eva (advisor) ; Potužák, Jan (referee)
Five indicators of water quality, namely biochemical oxygen consumption in five days, chemical oxygen consumption by dichromate method, nitrate nitrogen, ammonium nitrogen and total phosphorus, were determined in the river Stropnice. The samples were monitored at four offtake places along the river monthly during the year 2013. Twice a year water samples were analyzed also fromthe dischargeof the wastewater treatment plants. The results show that some changes of the individual parameters can be traced during the year, such as increase of oxygen consumption and total phosphorus in the summer months. However, no significant fluctuation was indicated for the measured parameters at any of the offtake places. Based on the values of the individual parameters water in Stropnice can be ranked to quality classes II. - IV. In the long-term frame of water quality examination from the year 2008 average indicators' values and characteristic values were determined. The results revealed that neither in this case substantial changes of water quality regarding the measured indicators can be observed.
