Constructed Treatment Wetland for Neratov Village
Kanta, Martin ; Pumprlová Němcová, Miroslava (referee) ; Kriška-Dunajský, Michal (advisor)
The municipality of Neratov is currently dealing with wastewater management, which includes the design of a new sewerage network and wastewater treatment plant. A pressure sewerage network and a wastewater treatment plant are currently being designed in the village, the design of which is the theme of the bachelor's thesis. With the latest development of the situation, the municipality is considering a reserve for a larger number of connected inhabitants as a way forward, so the whole work is designed from today's perspective as a partially oversized WWTP building. The introductory part of the bachelor thesis deals with the description of possible pollutants flowing into the treatment plant and their limits for discharge, the possibility of transporting wastewater to the treatment plant, types of mechanical-biological treatment plants and especially natural treatment plants, where the objects of pre-treatment, main stages of treatment. The second part deals with a specific design of the technological arrangement of a natural wastewater treatment plant. The practical part includes a description of the area of interest, the character of the village Neratov, the design of individual stages of treatment with a detailed description of the facilities at the treatment plant. The documentation also includes sample drawings, floor plans and sections. The proposed solution requires a minimum of electricity for its operation, it is a compact solution installed above the level of the existing terrain. The design also includes its own sludge management, ensuring the minimum possible operating costs.

Effluent-free treatment plant technology for small wastewater producers
Škarpa, Pavel ; Němcová, Miroslava Pumprlová (referee) ; Kriška-Dunajský, Michal (advisor)
The work aims to find new ways to dispose of wastewater. The theoretical part covers the currently known procedures for the discharge of treated wastewater into surface or groundwater, as well as the balancing of wastewater after previous accumulation. Furthermore, the theoretical part summarises the legislation of the Czech Republic concerning wastewater disposal. The measurement part deals with a new potential option, a sump with upstream water treatment. If the treatment is carried out on the principle of natural wastewater treatment, the volume of water can be reduced by evapotranspiration. Therefore, the aim of this work is to determine the realistic evapotranspiration of a vertical filter, to find a design methodology for a vertical filter to achieve optimal evapotranspiration and a suitable technological arrangement. Another objective is to use long-term air temperature records available from the Czech Hydrometeorological Institute database. The average daily evapotranspiration measured on the laboratory model reached a value of 4.5 mm/day in September 2021. In March 2022 it reached almost 2 mm/day. The equations for determining the potential evapotranspiration applied in the calculation part of the work achieved the highest agreement of 67.5% with the evapotranspiration measured on the laboratory model and will therefore be further developed to achieve much higher reliability of the calculation.
