Výzkum technologie vícestupňového filtračního systému kořenové čistírny / Research of the Multistage Constructed Treatment Wetlands Technology

Chaloupka, Ondřej January 2019 (has links)
The ways of purifying waste water produced by human society are nowadays a great deal. With the increasing pressure on sustainable construction, technology using principles close to natural processes are at the forefront. Treatment wetlands have been in use for almost 30 years and thanks mainly to developments abroad, they prove they are a suitable option for smaller producers of pollution. When designing a treatment wetland for municipalities with a larger amount of inhabitants, it is necessary to modify the proposal in order to eliminate all types of pollution. This thesis therefore compares three sewage treatment plants with a multistage filtration system. Comparing the achieved parameters will be beneficial for defining the rules for optimal design of these types of wastewater treatment plant.

Vaculík, Tomáš January 2019 (has links)
The diploma thesis is focused on Storm water management in urban areas. The first task for processing thesis was to arrange meeting with MČ Brno - Bohunice Ing. Antonín Crha, who has provided necessary information about the targeted location the and the reservoir for accumulation of rainwater collected. The practical part of the thesis is to capture the rainwater drainage in the existing rainwater sewerage system using the newly built pumping station and then pumping into the existing, unused reservoir. Accumulated water in the reservoir is planned to be used for the needs of the city, gardeners and other customers. The first part of the diploma thesis describes the management of refined water in the Czech Republic, Denmark and Germany. The first part also provides description of measures and technologies for the management of rainwater. Finally, there is description of the pumping station and borehole objects and the program for calculating the rainfall from the urbanized area. In the practical part of the diploma thesis the selected variants are described, rewarded and evaluated. The diploma thesis deals with two variants, that are guided along the same route, with the difference of the construction of the drilled well in the second variant. Both variants are handled by pumping. The option of the gravity inflow was rejected because of the large countersink of rainwater sewerage.

Odbourávání vybraných xenobiotik na komunálních čistírnách odpadních vod. / Removal of selected xenobiotics at municipal WWTP´s

Žižlavská, Adéla January 2019 (has links)
The development of the chemical and pharmaceutical industry and the massive use of synthetic substances in various industries has become indispensable for our society. Unfortunately, this progress has brought a whole new kind of pollution. It is a group of substances which imagine for living organisms’ greater risk than 'normal' organic pollution. Because they have extraneous origin compared with naturally occurring compounds, they are called "Xenobiotics." It is a group comprising a large number of different substances, with dissimilar physical, chemical and biological properties such as pharmaceuticals, pesticides, detergents, paints, varnishes, plastic packaging, food additives, cosmetic products, drugs, and many others. Although these substances began to enter the water cycle as early as 30 years of the 20th century, their concentration often moves to the limit of the detection limit, so their presence in the water began to be examined in more detail in the 1980s, following the development of analytical technologies chemical composition of water. The main danger of these substances is that doesn’t primarily effect on water quality, but directly affect on the organisms by confusing of the endocrine system or by directly damaging RNA or DNA, causing mutagenic changes, cancer-causing proliferation, birth defects, metabolic disorders, gender changes, the degeneration of reproductive capacity of entire populations or the disappearance of self-preservation instinct. The source of xenobiotics in the water cycle is predominantly wastewater, which generated through the wastewater treatment, which not designed to eliminate this type of pollution. he dissertation thesis deals with the issue of xenobiotics in wastewater and is divided into the theoretical and experimental part. The theoretical part summarizes the xenobiotics current state of knowledge in wastewater from their history, origin, classification, possibilities of elimination to impacts on the environ
