The results of thesis shows that Opatovice reservoir has not problems with water quality and its sediment is not phytotoxic.

The diploma thesis deals with wastewater and rating of efficiency of the wastewater treatment plant (WTP) Hodonín, which cleans communal and industrial wastewaters. Chapter of the literary research describes law regulations dealing with wastewaters, furthermore deals with water pollution, wastewater and wastewater treatment plant technological equipment. Next chapter contains characteristics interest area, its natural and economic conditions and traffic description in WTP Hodonín. I calculated efficiency for selected indexes for the period since 2003 to 2018 from the provided database from company Vodovody a kanalizace Hodonín, a.s.. This values of efficiency and values of concentration of these indexes were compared with emission standards stated in relevant government orders and processed to charts. Average values of efficiency in the observed period were always beyond required limits. Due to my own monitoring, were stated values of biochemical oxygen demand, total nitrogen, total phosphorus, nitrate nitrogen, ammoniacal nitrogen and orthophosphates by spectrophotometry. I calculated efficiency of cleaning from these values and compared them with relevant limits. The results showed that efficiency of cleaning in WTP Hodonín is about 15% higher than it should be due to legislative.

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.

The purpose of this thesis is to describe issues of wastewater systems and a design for separate sewage network in a particular village. Literary publications dealing with this particular subject and digital documents based on cadastral map were used to create the thesis. Drawing documentation of designed sewerage system is also part of the dissertation. Thesis is composed of two parts. The first part deals with the history of sewage disposal and treatment. Following familiarization with current trends in drainage of urbanized areas and the subsequent wastewater treatment. Types of wastewater, indicators of pollution and available options of draining from settlements are discussed. The second part is devoted to the practical part. Begins by describing the location of interest, continues with proposal of sewerage system and hydraulic dimensioning wastewater treatment plant. The benefit of this thesis is to deepen knowledge in the field of sewerage and waste water treatment. Another positive aspect is the application of knowledge gained in school examples to real practice.

The diploma thesis is facused on the wastewater discharged into surface waters in the village Nová Ves u Leštiny. Comparison parameters were with respect of flasitibility and economical demands. The suggested variants include a central wastewater treatment plant with a gravity separate sewer system or pressure sewage transport. Central root wastewater with a gravity separate sewer system or pressure sewago transport. Village will provide one-time financial contribution to individual households for acquiring domestic wastewater treatment plant.

En raison de son succès croissant avec les consommateurs la VoD (la Vidéo à la demande) gagne une ampleur sans précédent de l'IPTV et des industries de vidéo en continu tout comme de l’Internet. Contrairement aux services vidéo linéaires rigides programmant (qui sont la norme pour la TV d'émission), l'accès des contenus à la demande fournit une grande flexibilité permettant aux utilisateurs finaux de feuilleter et consommer le contenu vidéo d'une façon autonome / Due to its growing success with consumers as a preferred way to access video content, VoD (Video On Demand) services streaming is gaining unprecedented interest from the IPTV and the Internet video streaming industries alike. Unlike the rigid linear video services programming that is the norm in broadcast TV, the on-demand content access provides a great flexibility allowing end-users to browse and consume video content in a non-scheduled way. Besides providing a VoD offering to meet evolving end-users expectations for flexibility and differed-time access, it is today very important for a service provider to offer a very large content library (popular and niche content) to capture the broadest audience possible. Targeting a very large audience with a large video content library puts a very heavy burden on service providers with scalability being the chief design issue

This thesis is concerned with verifying the functionality of domestic wastewater treatment plants soaking in the Tišnov region. The theoretical section describes methods of waste water within the houses, their distribution, utilization characteristics. There is also described the technology selected domestic wastewater treatment plants method of operation. There are mentioned legislative provisions relating to wastewater treatment plants discharging to do their groundwater. The work includes hydro-geological description of the site, in which monitored Domestic wastewater treatment plant is located. Within the practical part was to validate the effectiveness of wastewater treatment. Samples of wastewater were regularly for six months removed from individual domestic wastewater treatment plants BAT and analyzed in the laboratory of the Institute of Agricultural, Food and Environmental Engineering Faculty of Agronomy, Mendel University in Brno. Measured parameters determining the quality of wastewater were compared with relevant legislation, the values guaranteed by the manufacturer of the individual household wastewater. Results of the analyzes of waste waters were evaluated interpreted. On the basis of their recommendations was established.

The thesis "Evaluation of the effectiveness of the wastewater treatment plant in Lipník nad Bečvou" compares the effectiveness of wastewater treatment before and after the plant reconstruction. This work is comprised of the theoretical and practical part. The theoretical part applies overview of the water law legislation, sewerage, types of wastewater and concrete methods of wastewater treatment. The practical part is focused on wastewater treatment in the city. Included is the transport of wastewater, description of treatment technology before and after plant reconstruction. Follows the graphical results of wastewater treatment plant load, analytic wastewater checks and effectiveness of the WTP (Wastewater Treatment Plant) in years 2005 and 2015. The results show that the original wastewater treatment technology was, according to compliance with the emission standards, insufficient. For this reason, complete WTP reconstruction followed. From the current WTP results, it is evident that the hydraulic load is at 50 % average, but it is overloaded with the substance. Despite this fact, WTP maintains its high effectiveness in pollution elimination. The levels of pollution on the WTP output do not exceed the values of the emission standards and limits.
