The waste management of the constructed treatment wetlands
Mrvová, Michaela ; Hyánková, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
The thesis is focused on the sludge management at root sewage treatment plants with focus on volum eis highest – sludge manahement. Sludge dewatering using sludge dryiing bed is still condemned designers mainly due to their lack of experience, while at the same time enforcing technologically complex solutions. Therefore, the thesis focuses on the break down balance hydrological equation sludge drying bed, which includes all parameters affecting water balance system. The result is a proposal not only design, but in particular a description of input data and the governing equations in software Reed-Bed, which is calibrated own operational results obtainde for the two sewage treatment plants (village Dražovice and Kotenčice). Reed-Bed software will perform sevetal functions: setting the ground area of sludge bed, investment costs required for the implementation of sludge bed, return on investment, the determination of moisture contene of sludge in the sludge bed and maximum lenght of the dewatering period with regard to wetland vegetation. The second largest item within sludge system creates biomass wetland plants, so work deals with possibilities biomass processing plant at the end of the growing season. Technological processing of biomass was tested on common reed, final product pellets for heating.

Provision of alternative refuse collection for a real estate surrounded by foreign property
Kvapil, Radek ; Štindl, Michal (referee) ; Klika, Pavel (advisor)
The thesis deals with possible ways of drainage and wastewater disposal. The issue of wastewater discharge to the environment has been closely monitored in recent years, and there is an apparent effort to improve the current situation.The dissertation discusses and compares three selected options – access to improved sanitation, building reservoirs and domestic wastewater treatment plant.The final section is dedicated to a comparison of acquisition and operating costs over time and to subsequent evaluation of the most suitable option. For the sake of clarity and assessment of potential solutions, the locality in the administrative area Vysoké Mýto - Domoradice has been selected as a model. The local authorities have been designing a public storm sewer, and given that it is surrounded by land, this issue will need to be addressed.

Welding of stainless steel in sewage treatment plant
Zána, Jiří ; Daněk, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
This bachelor thesis is dealing with stainless steel welding, especially for waste water treatment plants use. The thesis presents two most suitable stainless steel materials that eliminate fundamental disadvantages of other steel types. In the experiment three types of welding are tested for both materials and each weld is performed using two amperages. The weld bead and root WPS surface is evaluated for particular samples. For others the weld macrostructure is assessed.

Prices of constructions applied in landscape engineering projects
Kašová, Michaela ; Podhrázská,, Jana (referee) ; Tichá, Alena (advisor)
Thesis theme is Prices buildings in the landscape engineering projects. The work is divided into two parts, theoretical and practical. The theoretical part explains the concepts that appear in the practical part. In the second part is illustrated in the example shown computation overhead, comparing several types of prices that were created using a decoupling of the program, and create cards budgetary indicators for the catalog cost indicators of common facilities landscaping.

Study of variants of municipal sewerage
Juroška, Miroslav ; Macsek, Tomáš (referee) ; Hluštík, Petr (advisor)
The diploma thesis deals with the design of options for sewerage and wastewater disposal in the village Běleč, which is located in the South Moravian region. As part of the thesis, a detailed description of the area of interest was carried out, including the current and prospective state of sewerage system according to the water supply and sewerage development plan as well as the municipality's territorial plan. Thesis offers 4 variants of the technical solution for sewerage and wastewater disposal for the municipality of Běleč. Conceptually, centralized and decentralized solutions for wastewater management are proposed as variants. For individual variants, the economic demand was assessed in terms of investment and operating costs.

The draft of family house with focus on the ecological water management
Stupavská, Jaroslava ; Hyánková, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
The aim of my work is an optimal design of a detached house focused on ecological management of rainwater and household waste water. The work is divided into four parts: the first part deals with the design of the family house, the second part describes water as a medium used in households, in the third part I am dealing with packed home waste water treatment plants, and in the last, the four part, I approach the issue of root waste water treatment plants. My priority is the design of the family house with a water – saving solution. For the designed family house in Velká nad Veličkou, sewage treatment is provided by a vertical root waste water treatment plant, accumulation in the pond together with the filtered rainwater and their reuse in the facility as service water and in the garden irrigation. In the practical part of water management is the design of a sludge management facility. As the grassland is located around the house, a suitable irrigation solution is the location of the sprayers. Thanks to this type of solution, it is possible to save considerable money in management of drinking water and also to improve the microclimate site where the designed family house was built. In my work I wanted emphasise each household is able to efficiently and economically handle rainwater and waste water that can have a great impact on the water cycle in nature.

Natural dewatering of sewage sludge of small producers
Mrvová, Michaela ; Hynánková,, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
The thesis is focused on measurements possibility associated with sludge dewatering, realized on technological wetlands. Focus of this thesis is the evaluation of evapotranspiration in wetland macrophytes, respectively - comparison of three measurements - in the sludge drying bed to the greenhouse facility, sludge drying bed without the greenhouse building and measuring the meteorological station at 2.0 meters above the ground. One of the goals is an automated system monitoring and regulating moisture conditions in sludge dewatering. The aim of the evaluation is completed dewatering equipment from an economic point of view.

Study of variants of sewerage in the village Vír
Macík, Ondřej ; Macsek, Tomáš (referee) ; Hluštík, Petr (advisor)
Most of the municipalities in Czech republic have old or even disfunctional sewage systems for built up communal areas. General combined sewage systems built earlier are being today replaced by solutions separating rain waters and sewage waters. Municipality Vír has currently only few sewage branches that consequently flow into Svratka river. Aim of this Diploma Thesis is to propose 3 solutions for sewage produced in communal areas of Vír municipality and its consequent disposal in sewage treatment plant. Each of three solutions feature combined gravity-driven and pressure systems of sewage lines as well as water treatment in proposed MTB as well as household and container WTP. Each of three variant is economically weighed with proposed budget.

Cast-in-place tank of sewage plant
Sivčák, Jozef ; Šiška, Radek (referee) ; Strnad, Jiří (advisor)
The master’s thesis designs and checks the reinforced concrete tanks of sewage plant. Part of this thesis are also drawings. Tanks are designed as a watertight underground structure with aspect on standards and watertight function. Foundation slab and concrete walls were designed according to ultimate and serviceability limit states. The thesis includes design of reinforcement according to non-force effects in early stage. The structure is checked also to loss of equilibrium of a structure due to uplift by vertical actions from water pressure.
