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.

Study of the water management in a family house with an application of natural wastewater treatment
Kiszová, Radka ; Kriška-Dunajský, Michal (referee) ; Hyánková, Eva (advisor)
Bachelor thesis focuses on water management in the family house using natural treatment of waste water. Text partially deals with research in the area of treatment and reusing of rain and waste water in the case of a family house. Thesis concentrates on sources of waste water, their division and possibilities of reuse. When talking about waste water, main aim is to explain root waste water treatment. Second half of the text presents complex solution of water management in one particular family house. The actual amount of waste water is calculated for number of five equivalent residents, suggestion of its treatment, accumulation and enumeration of presumed amount of rain water captured. Shared storage is designed for both waste water treatment and rain water. This storage is subsequently used for flushing, washing and garden irrigation.

The study of modern treatment wetland for the Hlína village
Komendová, Denisa ; Pumprlová Němcová, Miroslava (referee) ; Kriška-Dunajský, Michal (advisor)
This thesis deals with the design of a modern constructed wetland for wastewater treatment for the Hlína village, Brno – venkov district (320 PE). Constructed wetlands are an alternative technology for wastewater treatment. In Czech Republic this technology often encounters a lot of problems arising from wrong design or improper operation. This problems cause insufficient cleaning efficiency, mainly in removing ammonia nitrogen. It is necessary to design the constructed wetland differently, thus make them a competitive against other waste-water treatment technologies, and ensure a higher cleaning efficiency mainly of ammonia nitrogen. The thesis is based on findings from exploratory and operating objects as results from cooperation with Institute of landscape water management. There are a new solutions and designs applied in this project, including several utility models. The first part consists of literature research, which summarizes basic knowledge on constructed wetlands for wastewater treatment. The result of the second part of the thesis is designed sewage treatment system, which comprises several serial and parallel connected sewage treatment elements. The aim is to not only eliminate the required pollution by decree law, but also to remove nitrogen and phosphorus. The part of the design is also a wastewater sludge treatment, based on innovated reed-bed systems with wetland vegetation.

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.

Concept of wastewater solution for village Třebešov
Chaloupka, Ondřej ; Pumprlová Němcová, Miroslava (referee) ; Kriška-Dunajský, Michal (advisor)
Water is the essential building block of life on the planet Earth. Its importance was overlooked in the past and quality of water in surface watercourses noticeably dicreased. It is an important fact, that according to the principles of sustainable development water became treated more economically and the water, wich people use, started to be cleaned properly before discharging back into the nature. One possible method is using of vertical sand natural filters. The Bachelor thesis deals with a possible solution of treatment wetlands for the village Třebešov. In this village there is located only an united sewer and therefore a water reservoir for rain water will be part of the design. In this water tank the rain water diluted with sewage will be cleaned through floating island technology.

Treated Waste Water Irrigation
Kohut, Rafael ; Hyánková, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
The thesis deals with the issue of simulation of treated wastewater irrigation by the HYDRUS 2D software. The first part of the thesis is designed as a theoretical research of academic information and knowledge. It aims at introducing the issue of treated wastewater utilization for the purpose of the irrigation. Furthermore it provides basic theoretical information on numeric simulation of the dissolved materials motion and transport in the soil. The last chapter of the theoretical part describes the calibration of the simulation by the HYDRUS 2D software. The second part of the thesis is devoted to the formation of filtration columns placed in the chosen site of the root zone wastewater plant. Within the filtration columns the automatic irrigation was formed and set off. Measuring of humidity in filtration columns was taking place for 81 days as well as the water sampling after the flow through the soil horizons. On the grounds of the measuring results the calibration of numeric simulation was carried out by the HYDRUS 2D software. The last part of the thesis presents the applications through the extending and alternation of the modelled setting. The main aim of the thesis is to calibrate the model and propose a general solution to advancement at realization of irrigation details when using the treated wastewater for the purpose of irrigation.

Study of Constructed Treatment Wetland Reconstruction for Dražovice Village
Roupec, Ladislav ; Pumprlová Němcová, Miroslava (referee) ; Kriška-Dunajský, Michal (advisor)
The constructed wetlands, which have been being created in the Czech Republic since early 90s, are designed so they do not allow successful removal of ammonia nitrogen. Almost all of these 300 registered constructed wetlands suffer from the colmatage which leads to the lowest effectiveness of treatment in nearly all parameters. The main effort of the Institute of landscape water management is to get rid of bad reputation and to clarify the reason that leads to unsatisfactory conditions of constructed wetlands. The diploma thesis focuses on the selected constructed wetland in Dražovice (850 EO), which removes ammonia nitrogen with the effect just below the limit values in the long term. The pressure of the Morava river basin and Department of environment (Building Authority in Bučovice) has led to the necessity of taking measures leading to the increase of treatment efficiency especially ammonia nitrogen. The diploma thesis includes both, actual project documentation concentrating on the adjustment of watercourse to nitrify ammonia nitrogen, and effective choice of suitable filtration material supported by testing method in situ. The practical part of the thesis deals with the implementation of the technical solution according to the project documentation. The adjustment of the constructed wetland is now nearly before completion. Last adjustments will be taking place during the spring 2017, the final inspection as well as the evaluation of the reconstruction will take place at the end of this year.
