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.
