Study on the potential of an integrated waste-to-energy unit
Freisleben, Vít ; Turek, Vojtěch (referee) ; Jegla, Zdeněk (advisor)
This diploma thesis is focused on the design of technological modifications of the existing industrial unit „waste-to-energy“, used for thermal treatment of process waste gases containing VOC and CO while flue gas is produced. The main objective of the existing unit modification is to improve its operating parameters considering economy, ecology and energy utilization. In the first part, the current industrial plant was presented with all necessary process data. Furthermore, all the key equipment used for the waste gases treatment or for the utilization of waste heat was identified. In the main part of the thesis there are performed modifications of the existing unit including the technology of existing heat exchangers intensification, the design of new and more efficient heat exchangers and finally the catalytic oxidation technology implementation for the decomposition of pollutants contained in the waste gas. The result of the thesis is a technical, economic and ecological comparison of the proposed technological modifications with the existing operation.

Possibilities of technical implementation of intensification the constructed treatment wetland
Suchánek, Pavel ; Kriška-Dunajský, Michal (referee) ; Pumprlová Němcová, Miroslava (advisor)
The Bachelors thesis is a study of three variants of solution of reconstruction and intensification of specific constructed wetland. Request for reconstruction of existing cleaner facility arose from an observer, who demanded increasing of cleaning efficiency because of expected changes on sewer. The introductory part deals with a theoretical summary of expert knowledge and information, which are responsible for familiarization with problematics of constructed wetland. Just the information about reconstructions of others constructed wetlands could be essential for solving this thesis. Based on the results of the progress and effectiveness of the proposed changes, it is possible to be inspired for further solutions. Practical part of thesis is a separate study, within which were proposed three variants of solution. Variants differ in economic and technical difficulty and are linked to each other. The first one is the least difficult option and serves only for maintain temporary state. The second variant includes complex reconstruction of the object using a vertical filter and ensures effective removal of observed pollution parameters (Suspended solids, COD, BOD, N-NH4+). The third option, economically and technologically the most demanding, should moreover chemically precipitate phosphorus. For clarity of the proposal were all variants compiled in 3D model. The aim of thesis was to elaborate several variants of solution of reconstruction and intensification of existing constructed wetland Biskoupky so that the operator can choose the one that suits him at most, taking into account the investment aspect.

Intensification of wastewater treatment plants
Kudrnová, Eliška ; Žeravíková, Jana (referee) ; Hluštík, Petr (advisor)
This thesis deals with the intensification of wastewater treatment plants, which includes improving and strengthening of performance of existing treatment units. The introduction briefly discusses the ways of discharging wastewater from agglomerations, their influence on the WWTP and types of WWTP currently used. The following are the conditions for wastewater treatment, discharging wastewater and waste water management according to law and the factors influencing the intensification of wastewater treatment plants. The main content of this thesis is focused primarily on WWTPs with a capacity greater than 2,000 pe, which had until the end of 2010 meet the requirements of Council Directive 91/271/EEC to be equipped with an appropriate degree of secondary treatment. The practical part is focused on the evaluation of WWTP constructed, reconstructed and intensified between 2008 and 2010.

Towards the understanding of agricultural intensification impacts on farmland birds: the effects of changes in invertebrate food supply
Hološková, Adriana ; Reif, Jiří (advisor) ; Lučan, Radek (referee)
Populations of insectivorous farmland birds recently underwent dramatic declines. Agricultural intensification is the main cause of these population changes, but involves numerous different mechanisms. Changes in food supply are thought to be one of the key factors. Homogenization of diet supplied to insectivorous chicks reduces their growth rate resulting in their smaller size as adults; decreased abundance of prey affects both survival and fitness of chicks and the overall breeding success. The accessibility of food is one of the most important factors limiting the use of food-rich habitats. However, the impact of all these factors on population trends has been shown in a single species - grey partridge. While the effect of changes in food supply on the breeding success has been confirmed in many other species, there is a lack of information on subsequent links to the survival of fledglings and the major causes of mortality outside the breeding period remain unclear. In general, there is insufficient information on population consequences of the changes in food supply for farmland birds, particularly in Central and Eastern Europe - the region with different characteristics from those we find in regions in which most of the findings were collected. Without this information, it is difficult to...

Population densities and habitat preference granivorous birds (\kur{Passer domesticus, Passer montanus, Streptopelia decaocto}) in human settlements.
BANDHAUEROVÁ, Jaroslava
The most often mentioned causes of decrease in a number of granivoric synantropic birds are primarily changes in agriculture (liquidation of factory farming, using of pesticides, effective methods of harvest, consequences of intensification of agriculture) and changes in socioeconomical status of population (higher care of public green, decrease in numbers of small poultry farms, modernization of buildings etc.), which results in lack of food and opportunity to nest. Goal of this work is primarily evaluate an influence of the agricultural methohds on numbers of the house sparrow (Passer domesticus), tree sparrow (Passer montanus) and collared dove (Streptopelia decaocto) set a preference of habitats for selected species, addiction of their occurence on presence of small poultry farms and factory farming and compare the results with winter monitoring. Then evaluate preferences of nest habitats for house sparrow (Passer domesticus) and tree sparrow (Passer montanus). Monitoring was made in 48 chosen locations in the Czech Republic (most of those locations in South Bohemia) during the nesting period (February May) in years 2015 2016. The data evaluation was made through computer software Microsoft Excel and R v. 2.8.1 (2008). The research shows that factory farming has essentional influence on occurence of all three selected species and difference in occurence between winter and the nesting period is demonstrable. Also the difference in presence of collared dove and house sparrow is demonstrable near factory farms.
