Zdroje vody a čerpací stanoviště pro požární techniku v okrese Písek. / Water resources and water pumping sites for fire equipment in Písek district.

VIKTORA, Vladimír January 2011 (has links)
In my diploma thesis I have created the updated version of water sources and pumping sites for fire equipment in the Písek district. I acquired large volumes of data by a detailed physical inspection of possible water sources in all villages in the Písek district. In my thesis I have mentioned water sources only in those villages that are classified into fire protection units, category II and III. The complete summary of all water sources and water pumping sites is on the attached CD. The data contain the name of the village, type of water source, GPS coordinates, additional information about the water source and any additional notes regarding repairs, distances from the village, etc. Photo documentation and the map section were produced for each water source. In many villages, there are hydrant networks which, in those villages where there is no water source, can have a substantial effect on fire safety. The thesis also includes the list of all hydrant networks in the Pisek district, including the owners and operators. The thesis can be used for the Operating and Information Centre of the Fire Brigade for the South Bohemian region which, for the demand for water for rescue and liquidation can send the unit directly to the water source according to the ascertained data. For some water sources, below the table in the note, there may be corrections or improvements that lead to a better use of these sources. The thesis monitors the existing status of the water and pumping sites for fire equipment in the Pisek district. I compared the acquired data with data from South Bohemian Region Regulation No.4/2003 at 2.12.2003. It results from the compared data that permanent updating and communication on the part of the municipalities with the Fire Brigade is necessary. In many places, water sources are closed and new water points originate with the possibility to pump this basic and main extinguishing agent.

Mikropolutanty ve zdrojích vod a možnosti jejich odstranění / Micropollutants in water resources and ways of their elimination

Lukášová, Daniela January 2018 (has links)
The diploma thesis deals with micro-fuels in drinking water sources and their subsequent removal. In the thesis mainly pesticides and pharmaceuticals are described. The reader is first introduced to the most common pesticides occurring in water and their consumption. Drugs are described in a similar context. In addition, there are practical studies on the occurrence, degradation and removal of micro-pollutants from water. The final thesis is a laboratory experiment dealing with the removal of salicylic acid from water by filtration through the filtration material Bayoxide E33 and activated carbon. The thesis describes the procedure and results of the experiment.

Efektivní pokrytí potřeby tepla s pomocí solární soustavy / The effective coverage of the heat demand using solar system

Vítek, Lukáš Unknown Date (has links)
This master thesis aims to design the heating system and HDW preparation in an apartment building. The first variant deals with condensation gas boiler as the only energy source, while the second variant combines the gas boilers with the solar thermal system. The apartment building is located in Prag and has three above-ground floors and a basement. In the basement is the technical room. Convectors are being used for heat distribution. The theoretical part deals with the introduction to the solar thermal system.

Návrh rekonstrukce přivaděče surové vody pro úpravnu vody / Reconstruction proposal of raw water supply for water treatment plant

Pasnichenko, Dmytro January 2021 (has links)
This diploma thesis deals with the assessment of the technical condition of the raw water supply Dnipro-Mykolaiv for water treatment plant Inhulets in Ukraine and the reconstruction proposal of the section of this supply. Specifically, it is a 300 m long section of the steel pipeline DN 1 400 of the first row of the sypply near the Myrné village in Bilozerka Raion (district), Kherson Oblast (province), Ukraine, which is in a state of disrepair. As part of this work is an an evaluation of the current technical condition of the pipeslines of the first and second rows of the suplly. Subsequently, the design of the reconstruction of the section is then carried out using selected remediation technology.

Posouzení hydraulické spolehlivosti systému odvodnění v urbanizovaném území a řešení odvedení extravilánových srážkových vod. / Assessment of hydraulic reliability of drainage system in urban area and solution of extra-urban storm water.

Šebek, Josef January 2021 (has links)
This diploma thesis presents the topic of urban drainage systems. The first theoretical part contains methods and options for urban drainage systems, stormwater management, blue-green infrastructure (BGI) in urban areas and introduction of numerical modelling of sewerage systems. The application of modelling platforms is further described in the feasibility study in the practical part of this thesis. By using the simulation model, the study assesses the hydraulic reliability of the drainage system in the city of Jedovnice in the Czech Republic, identifies hydraulic issues and their causes on the urban drainage system. The second part of the study assesses extra-urban stormwater inflow from fields around the city caused by heavy rainfalls, which causes local flooding in the urban area. The identification as well as proposed solutions and capital expenditures, their comparison and recommendation of the optimal solution are included in the study.

Fotokatalytický rozklad vody oxidovými polovodiči modifikovanými grafenem/grafenoxidem / Photocatalytic water splitting by oxide semiconductors modified with graphen/graphenoxide

Marek, Jiří January 2015 (has links)
This master thesis deals with the topic of alternative production of hydrogen as the energy carrier of the future. The primary focus is on the production of hydrogen based on photocatalytical water splitting in the presence of semiconductor materials (especially modified and unmodified TiO2). The aim of the thesis is a synthesis of nanostructured oxide, graphene/graphene oxide particles and its composites, and a study of its structures and photocatalytical properties regarding photolysis of water. Products of the syntheses are described from the point of view of phase composition, surface area and photocatalytical activity. The main output of the thesis is a discussion of the influence of alkaline complex forming reagents on the hydrothermal low-temperature synthesis of biphasic TiO2, and a study of the influence of graphene/graphene oxide modification on photocatalytical activity of biphasic TiO2.
