The prediction of the risk by wastewater irrigation
Burešová, Erika ; Sládek, Roman (referee) ; Kriška-Dunajský, Michal (advisor)
The thesis deals with the issue of simulation of treated wastewater irrigation by the HYDRUS 2D software. The first part of the thesis is designed as a literary research of academic information and knowledge. It aims at introducing the issue of treated wastewater utilization for the purpose of the irrigation with an emphasis on the Czech Republic. The following is an overview of important hydropedological characteristics of soils, the theoretical basis of numerical modeling of movement and transport of solutes in soil and the use of HYDRUS 2D software. The practical part is based on theoretical knowledge and demonstrates the creating process of mathematical model in program HYDRUS 2D, simulating the transport of input pollution in the soil profile. Wastewater used for irrigation was treated using a system of mechanical pretreatment and horizontal filters planted with macrophytes situated on a CW Drazovce. This work describes the calibration and subsequent application of calibrated models for monitored pollution parameters NH4+-N, P-PO4-3 and COD.

Monitoring and evaluation the first year of operation of the vertical flow filter in constructed wetland
Vláčil, Lukáš ; Kriška-Dunajský, Michal (referee) ; Pumprlová Němcová, Miroslava (advisor)
This Bachelor’s thesis evaluates the one-year operation of a new type of vertical filter bed in the constructed wetland in Dražovice. This evaluation will be used to compare the efficiency of treatment – ammonia nitrogen removal – in the Dražovice constructed wetland before reconstruction (the installation of the vertical filter) and after the reconstruction. The introductory part deals with the theoretical research summarizing expert information and learnings, in order to provide insight into the issue of constructed wetlands and vertical filters in particular. Individual technological installations are described and the operating principle of constructed wetland technology is explained. The practical part of the thesis describes and evaluates the treatment efficiency of the vertical filter installed in the Dražovice constructed wetland in 2016. The results evaluation focuses on two indicators: N-NH4+ and CODCr in the period between January 2017 and May 2018.

Modelling of the biochemical processes in the constructed treatment wetlands
Pumprlová Němcová, Miroslava ; Hyánková, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
This master's thesis deals with the modeling of biochemical processes in saturated vertical filter (which is often part of constructed treatment wetland) using software HYDRUS 2D and the module Constructed Wetland CW2D. The introductory part of this thesis is the literature research of expertise that are introduce with the theme constructed treatment wetlands and should also provide a basic overview of the mathematical or numerical modeling issue. The last chapter describes the theoretical introduction of software HYDRUS 2D and CW2D module, it is the practical part used to create a numerical l model. The practical part is based on theoretical knowledge and demonstrates the creating process of mathematical model in program HYDRUS 2D, simulating the real biochemical processes on the vertical saturated filter. The model is created in the program HYDRUS 2D CW2D and based on real operated constructed wetland. The thesis describes the calibration and followed verification of this model. The final model can well simulate the real filter behavior and allows user to get information about the output concentrations of waste water emission, such as ammonia nitrogen (N-NH4+) and chemical oxygen demand (COD). The results should in the future contribute to create software intended to draft and layout constructed wetlands.
