Wastewater treatment plants for municipalities with gravitational inflow
Benešová, Irena ; Vachovec, Roman (referee) ; Hluštík, Petr (advisor)
Diploma thesis is aimed on description of wastewater treatment plant with gravitational inflow. Focus is on WWTP in the Czech Republic, particularly in the South Moravia region - in this aspect the thesis presents relevant statistics like the number of WWTP per region and the total, capacity of WWTP per region and their substance load on inflow /outflow. The recherche is also limited according to the core subject of theoretical part, which is technology of small WWTP in the category up to 2000 equivalent habitants. The experimental part presents comparsion of particular wastewater treatment plant of this category in the South Moravia region: one with gravitational inflow and one with inflow pump station. The examined wastewater treatment plant are compared according to substance load, hydraulic load and technology. Thesis is concluded with a review of the different operation parameters of the both types of WWTP.

Removal of selected xenobiotics at municipal WWTP´s
Žižlavská, Adéla ; Rusník,, Igor (referee) ; Bodík,, Igor (referee) ; Hlavínek, Petr (advisor)
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
