Failure rate wastewater treatment plants
Boryśová, Michaela ; Vlčková, Veronika (referee) ; Hluštík, Petr (advisor)
This thesis deals with the sludge management in wastewater treatment plants. It provides a basic overview of methods for modifying risk material in sludge ending. The main goal of this work is to create a fault trees based on faults which occurred in the sludge management facilities. Furthermore, it was created frequency of failures assessment of the objects on wastewater treatment plant in Hodonín. Provided information were obtained during excursions of WWTP Hodonín and Zbýšov.

Dependence of Sludge Dewatering efficiency on amount of flocculant
Volejník, Tomáš ; Medek, Jaroslav (referee) ; Boráň, Jaroslav (advisor)
The target of the first part of this diploma thesis is focused on the problems relating to the sludge production from the wastewater treatment plant and subsequent sludge treatment. Wastewater treatment plant and individual processes from the sludge management are described. The process of the sludge dewatering is described more extensively. Various methods of the dewatering and materials balance are described, too. The second part of this thesis is based on the experiment which took place on wastewater treatment plant Tetčice. The influence of the polymeric organic flocculant dosing on the sludge dewatering was monitored by this experiment. Dependence of the sludge dry matter and filtrate suspended solids content on the specific amount of flocculant was evaluated from experiment’s outputs. Using materials balance and outputs of the experiment, economical balance was made. It made possible to choose the most economic and technologically optimal way of the sludge dewatering on wastewater treatment plant Tetčice.

Wetlands of the Brdy Mts.
Hyklová, Jana ; Karlík, Petr (advisor) ; Hana, Hana (referee)
This bachelor thesis examines especially peat wetlands located on the territory of Brdy and Podbrdsko. Specifically, it looks into ten locations that were in various degrees affected by anthropogenic effect. The purpose is to identify historical and current status of these biotopes, to deduce the nature of past changes, identify the causing factors and then propose appropriate protection solutions. Attention is also paid to the newly created protected landscape area of Brdy and extreme drought in 2015. Depth of the humolit, hydrological conditions and diversity of species were all monitored at the locations and the vegetation cover was briefly characterized. Mining, which often led to the degradation, took place in all the monitored areas in the past. The best preserved Brdy´s peat with bank of Pilska's reservoir. The territorially largest peat bog with the highest measured depth of humolit is located on the eastern littoral of Horní padrťský pond. Both of these areas have absolute protection priority. If the landscape will not face any unexpected changes, it can be with appropriate chosen management assumed sustainable state in the following locations: Dolní Padrťský pond, Tok and the pond Tisý. The wetlands are known to be formed over hundreds of years therefore it is our aim to keep these endangered biotopes preserved for the future.

Možnosti zpracování kalů z úpraven vody
Koukalová, Dana
This bachelor thesis deals with possibilities of processing sludge from water treatment plants. The aim of the thesis is to describe the current possibilities of its processing, use or disposal in accordance with present legislation of the Czech Republic and give specific examples of sludge processing from four different water treatment plants. The thesis is divided into theoretical and practical parts. The theoretical part deals with the principles of water treatment, waterworks sludge development in water treatment plants, its composition, characteristics and possibilities of its use and subsequent disposal. The practical part deals with specific examples of sludge management in selected water treatment plants in the Czech Republic.

Vliv hospodářských zásahů na změnu v biologické rozmanitosti ve zvláště chráněných územích: Monitorování změn vegetace a populací zvláště chráněných a ohrožených druhů rostlin a živočichů v NPR Novodomské rašeliniště
Okresní muzeum, Chomutov ; Vysoký, Václav ; Tejrovský, Vít ; Němcová, Lenka ; Hajer, Jaromír ; Buchar, Jan ; Ondráček, Čestmír
Cílem průzkumu je sledování změn ve složení vegetace a populace zvláště chráněných a ohrožených druhů vyšších rostlin, mechorostů, obratlovců a vybraných skupin bezobratlých ve vztahu k odvodňování, k působení jelení zvěře a ke změnám globálního charakteru. V roce 2002 byl dokončen průzkum celého rašeliniště. Byly evidovány játrovky, mechy vyšší rostliny. Průzkum bezobratlých byl rozšířen na arachnofaunu. Dále byl průzkum zaměřen na ověření výskytu ptáků zařazených v Příloze I směrnice EU o ptácích. Mimořádná pozornost byla věnována zpracování a vyhodnocení ohrožujících faktorů pro vybrané druhy zvláště chráněných ptáků (chřástal polní, žluna šedá a moták pilich). Zvláštní péče byla věnována zpracování managementových opatření pro tetřívka obecného, žlunu šedou, motáka pilicha, chřástala polního, sýce rousného a bekasinu otavní.

Zhodnocení dlouhodobého vývoje chemismu vody Stropnice v úseku Údolí u Nových Hradů - Petříkov
Čeřovská, Kateřina ; Pokorný, Jan
Evaluation of long term development of chemical parameters of Stropnice river. In: Pithart,D.: Ecology of alluvial oxbows Natural floodplain (c. 800 ha) of Stropnice river near town Nové Hrady was drained and converted into agricultural land in 1980s. The natural meandring stream was straightened and deepened about 2m under the soil surface level. A high profile of flood plain soil was exposed to mineralisation and water flow from the region was accelerated. Data on water chemistry and flow rates collected before and after the drainage were evaluated. Alkalinity, conductivity, concentrations of base cations have increased after drainage which supports hypothesis that drainage accelerates matter losses from the landscape.
