The water flow simulation in the cesspit
Šrámková, Dagmar ; Hyánková, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
This diploma thesis consists of two parts, part research and part attachments. The first section describes the literary problems of today's way of cleaning wastewater from small producers and characteristics of wastewater. The work is focused on the aspect of nature and all of these methods are directed towards this direction. The literary section is devoted to anaerobic environment, which is just one of the natural ways of treatment of waste water, in our case in a septic tank. The second part of the thesis deals with modeling of flow and behavior of sludge and water mixture in the cesspit septic tank sludge with variable densities and flow speeds. Modeling and calculations are made using COMSOL Multhiphysics. The conclusion is then summarized findings from the flow cesspit septic tank with the results and the assessment of whether a septic tank still has its place among the modern methods of wastewater treatment.

Study of variants of sewerage of the recreational center Vřesovice
Krulová, Martina ; Frajt, Tomáš (referee) ; Hluštík, Petr (advisor)
The diploma thesis deals with the possibilities of sewerage and wastewater disposal in the recreational centre near Vřesovice. The purpose of the diploma thesis is the elaboration of variant solutions of sewerage, including the proposal of possibilities of wastewater treatment, economic evaluation of variants, their subsequent comparison and recommendation of the most suitable variant. The diploma thesis deals with the design of variants of wastewater treatment with subsequent discharge into surface waters. Finally, the advantages and disadvantages of the individual variants of sewerage are summarized with a comparison of costs and subsequent recommendation of the variant.

Sewage and it's cleaning at sewage water treatment plant in the village Ostrožská Lhota
VANĚČKOVÁ, Hana
All of us produce large volume of wastewater every day. But we care about the environment more and more which brings building of new sewerage plants as well. Nowadays, there is an intensification of old sewerage plants and many new ones are being built. In the past, sewerage plants belong only to the cities, but now they can be found even in the villages. People should also know what they release into sewerage and they should be aware of it. We should not rely only on a sewerage plant because it can not remove all the unwanted substance either. In my bachelor´s work on the theme ?Wastewater and its treatment in the sewerage plant in the village Ostrožská Lhota?, I deal with the present status of the sewerage plant in the village, the wastewater treatment system and wastewater in general as the theme indicates. The work is divided into two essential parts ? the theoretical and the practical one. Firstly, I described the former wastewater discharge in the theoretical part. Then I described the wastewater division and wastewater itself. Finally, I wrote about the sewerage plant, mainly about wastewater supply and its subsequent circulation. The next part is the practical one. My own research was a part of it. It was a quantitative form of research. The research was done by the method of questioning, in the form of questionnaires. The questionnaires were distributed to the residents of Ostrožská Lhota, people above 18. It was a random sample of people. 130 questionnaires were distributed in total. The obtained data are processed and analysed by means of charts. The secondary data analysis which was done by means of measuring data on inflow and outflow belonged to the practical part as well. Afterwards, the data were processed into charts. I set three goals in the work. The first goal was to evaluate the wastewater quality before the construction of the sewerage plant in the village Ostrožská Lhota. The second goal was to evaluate the effectiveness of wastewater treatment in the sewerage plant in the village. I tried to reach these two goals by means of secondary data analysis where I use the chart of measuring data on water inflow and outflow. I compared these figures with the limits of measurement ? limits which are set for the sewerage plant by the water resource management. I found out that the sewerage plant meets all the requirements and it does not exceed the limits. The measuring data are even below the limits. Lastly, the third goal was to find out the households´ opinion on wastewater pollution. I investigated on this goal by the help of the questionnaires. All the set goals were fulfilled. The testing results show that wastewater satisfies the limits of the water resource management and the people are aware of the discharged wastewater quality. This bachelor´s work can function as a recommendation when potential insufficiency is found. It can be also an educational material for non-professionals who do not know this topic and questions.

Early Modern archaeological assemblages from Prague Castle and period written and iconographic sources
Blažková, Gabriela ; Frolík, Jan ; Žegklitzová-Veselá, Jana
The main goal of this work was to introduce Early Modern finds of ceramics and glass from Prague Castle. As a starting source for this study were used eight find collections of cesspits originating from the Prague Castle area belong to houses located along the northern and western edge of the Third Castle Courtyard. The above mentioned collections of finds represent mainly features unearthed in the years 1925-1932 or 1957. The only recently discovered cesspit represents a feature (OBJ. 1) from the House No. 34/IV on the Jiřské square. The study is attempting to answer the question, in the cooperation with archive sources, how much can the cesspit-fillings reflect social position of their users.
