This master thesis deals with the design of a wastewater treatment plant, which will be controlled by a PLC. The theoretical part describes the types of wastewater and sewage systems that are important in the design of wastewater treatment plants. The thesis also describes programmable logic controllers, theirs programming languages, SCADA (Supervisory Control And Data Acquisition) systems and automation.The thesis also deals with theoretical description of wastewater treatment plants, their functions and security. Next part describes the design of the wastewater treatment plant. The last part of the thesis describes implementation of the wastewater treatment plant controlled by a PLC.

The theme of master thesis was to cover issues of controlling the wastewater treatment plant, to introduce latest standards applied in design of graphical interface and design the set of fucntional and graphical objects. First parts focuses on listing of power devices, sensors used in wastewater plant and issues of its control, followed by HMI standards introduction. Practical part contents of configuration of control system, desription of functions with flowcharts. Subsequently the thesis covers specificall graphical objects and its connection onto functional blocks.

Solární sušení je mimo jiné energeticky nenáročná a tudíž vysoce ekologická cesta pro zpracování kalů z malých čistíren odpadních vod. Výsledkem tohoto procesu je produkt, který je velmi dobře použitelný v zemědělství jako přírodní hnojivo. V rámci této práce bude sestaven zjednodušený dynamický model sušení vrstvy kalu s jednou prostorovou souřadnicí. Tento model bude diskretizován pomocí vhodné numerické metody a bude provedena jeho implementace do výpočtového programu v prostředí MATLAB.

This thesis deals with the design and static assessment of a concrete part of a sewage treatment plant. Specifically, the calculation and assessment of the base plate, external walls, internal walls and ceiling slabs, elaboration of shape and reinforcement drawings of selected structural element. The concrete part of the Sewage disposal plant is all below ground level. Static system and the calculation of internal forces was carried out in Scia Engineer 2011 - student version.

The theme of the dissertation is structural survey of designed sewage clarification plant. The work deal about designed of reinforcement of the sewage clarification plant. The diameter of the reservoir is 17,8 m and the depth is 6,2 m.

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 subject of this diploma thesis is the preparation of project documentation for the implementation of new sports and cultural centre Otradov. The dominant feature of the complex objects stands and multipurpose hall. The building is architecturally designed with an effort to fit in too much of rural architecture. Multipurpose hall has two floors, one third roofed flat roof, two-thirds of the roof ridge. The core system is aerated concrete blocks. The building is two-storey grandstand with the carrier deck. Roofing is solved by means of broken wooden beams. Sanitary facilities is dealt wall system and roofed shed roof. Athletics track, the surface of the polyurethane mixture designed for sports.

The objective of the Diploma Thesis, which is divided into two parts, is to summarize the issue of wastewater treatment for teaching purposes. In the theoretical part, it is possible to find interesting facts from the history, the beginnings of sewerage in the Czech, treatises on sewage, urban and industrial sewage. The thesis describes waste water, its composition and explains the concept of sewerage. The most extensive chapter is the section on sewage treatment plants. It deals with the type of sewage plants, cleaning processes and water and legislation. Readers will be informed about the drainage in Benesov and the sewage treatment in this city. An integral part is the issue of sewage treatment plants for family houses and root cleaner. The empirical part focuses of the questionnaire examines the relation of school facilities to sewage treatment and especially the use of worksheets. There is a work sheet for pupils II. grade or primary school or the relevant years grammar schools was check in primary school Benesov, Dukelska 1818. The practical part also includes a design of the excursion to the seweage treatment in Benesov. The aim of the thesis is to work on the issue of water purification, which could serve teachers as a guide to the teaching of pupils, they are able to answer the questions...

The topic "Environmental Security of Wastewater System" was selected for the creation of my thesis by several fundamental reasons.The main one is the vital importance of water for the functioning of human society.Drinking water sources are limited and the current relatively easy access to good quality water leads to irresponsible waste of this commodity.Besides wasting there is another big problem with environmental pollution,which is closely related to the degradation of sources of drinking water.With the increase of human population,environmental conditions began to worsen rapidly and this issue became to be discussed by multinational organizations.The so-called Environmental Security is currently very topical subject.It is introduced gradually into school curricula.Large amounts of funds have been invested to the environmental safety of water management in the past few years.An especially,there have been build many waste water treatment plants.The thesis is oriented locally on the municipality of Příbram.Its administrative area covers 74 municipalities and military training area of Brdy.The administrative area is mostly formed by smaller communities that are self-sustaining in water management.It is necessary to ensure sufficiently good conditions of the environment to prevent its degradation.The aim of this thesis is mainly to map the impacts of failure of sewage system and eventual propose of appropriate interim solutions of such failure.The research question is closely related to it: What is the current level of environmental safety of water? To achieve the set objectives,primarily I applied the method of literary research,through which was described the basic information necessary to understand the issue.It was also used method of qualitative research,which was carried out on the basis of interviews with experts in that field.The collected data were organized in a logical survey and analyzed by the a SWOT analysis.The thesis is divided into two main sections.The first one is a theoretical part,which describes the water cycle,explains what is infrastructure and,consequently,it highlights the importance of critical infrastructure.It also explains the concept of water management and presents the basic characteristics and methods of processing and treatment of drinking and waste water.It also states the basic legislation governing the issue of water and ultimately defines the concept of environmental security.The second part describes the sewage system in the area of Příbram and maps the ways of creation and the subsequent magnitude of failure of analyzed wastewater treatment plants.In direct relation to this,it assesses the possible emergence of environmental impact.Waste water can be divided into several groups according to where and how they arise.Taking account of their origin,wastewater may contain a wide variety of harmful substances.A failure of the wastewater system would be not only a current problem of environmental pollution at the site where the waste water was getting into the nature,but a long term adverse effect,which would be later manifested in the form of,for example,contamination of soil and groundwater,which would subsequently mix with drinking water resources.It could also lead to the death of some animals,disabling eating crops in that location and spread of various infectious diseases.This condition is highly undesirable and therefore it is necessary to implement preventive measures to prevent environmental safety.From this research,it was found that the formation of potentially serious impacts on the environment due to the failure of the sewage disposal plants in the area of Příbram is not expected.The operators are ready to remove immediately and quite efficiently incurred defects in order to avoid serious long-term failure.In relation to this,the environmental safety of the sewage disposal plants in the area of Příbram can be evaluated as very good.
