Control Systems for the Technological Process Model
Řegucký, Jakub ; Baštán, Ondřej (referee) ; Jirgl, Miroslav (advisor)
This work deals with systems and industrial controllers. The design of a model of a real technological process is demonstrated on a sewage treatment plant. A dynamic systems simulator serves to get an appropriate configuration for the chosen model which is then connected to a control system, measured and identified with the Matlab System Identification Toolbox. The calculation of regulator parameters and a process control is found in the second part of this work.

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.

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.

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.

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.

Seasonal evolution of antibiotic concentrations in the wastewater of STP České Budějovice
JANOŠÍK, David
The aim of the diploma thesis was to monitor seasonal concentration changes of 7 antibiotics norfloxacin, levofloxacin, ciprofloxacin, azithromycin, erythromycin, trimethoprim and sulfamethoxazole in wastewater influent and (cleaned) water effluent in the Sewage Treatment Plant (STP) České Budějovice. Time-proportional 24 hours pooled samples of wastewater were collected every month from March 2011 to February 2012 in the influent and effluent pof the STP. The concentrations of target compounds were determined by using in line SPE/LC-MS/MS analysis. The highest average concentration in the influent was detected in case of norfloxacin (0.563 microgram/l) and ciprofloxacin (0.406 microgram/l). The highest average concentration in the effluent was detected in the case of trimethoprim (0.255 microgram/l) and erythromycin (0.117 microgram/l). Higher concentration of antibiotics was measured in the colder periods of the year. It was connected with increased use of antibiotics and with less cleaning efficiency of the STP in this season. The highest removal efficiency was determined for norfloxacin and ciprofloxacin, the lowest for erythromycin. The influence of the season on the removal efficiency of antibiotics was found esp. for azithromycin,trimethoprim and sulfamethoxazole.

Influence of common sources of communal pollution on aquatic environments
ŠATRA, Václav
The aim of the thesis was to assess the impact of current sources of sewage treatment plant (STP) located upstream on the contamination of the aquatic environment. In 2009 contamination assessment was carried out at three selected sites located within the municipal sewage treatment plant and at three sites located above these potential sources of pollution. Brown trout (Salmo trutta m.fario L.) was the indicated species. The presence of MUSK materials , brominated flame retardants (BFRs) and organochlorinated persistent pollutants (POPs) was being detected within the selected samples of fish muscles and sediments.
