Use of constructed wetlands to improve quality of water polluted by agricultural activity- so-called Integrated constructed wetland (ICW) concept.
ŠESTÁKOVÁ, Petra
This work represents the grant application for project dealing with a design of constructed wetland for agricultural wastewater treatment.
Function of the root wastewater treatment in case of two wastewater treatment stations in Třeboň Biosphere Reserve.
MUNDOKOVÁ, Mariana
The Bacherlor´s thesis monitors the concentrations of certain chemicals in waste water. The locations of this testing operation were Příbraz, a constructed wetland that has been operating for nine years and Rosec also a constructed wetland in testing operation. This project shows the physical construction and the function of constructed wetlands. It also reports on the levels of the BOD 5, COD and TSS. From our monitoring records the efficiency for BOD 5, COD and TSS has been steady over the study period for both locations. Only once for a period of four months outflow concentration of TSS was higher the due to increased inflow of constucted wetland TSS at the Roseč.
Accumulation of selected risk elements in plants growing in constructed wetlands for wastewater treatment.
VANČUROVÁ, Ivana
The aim of this bachelor work is to provide a literature survey aimed at the accummulation of risk elements by plants growing in constructed wetlands. The results of the survey revealed that less than 2% of the inflowing amount of risk element sis sequestered in the aboveground reed biomass. The highest concentrations were measured in roots while relatively low concentrations were found in rhizomes and aboveground biomass. Concentrations in Phragmites roots were usually higher than those in Schoenoplectus. The accumulation of risk elements was the highest during winter for Phragmites and in autumn for Schoenoplectus. Both plant species were found to be root accumulators of Pb, Cu, Mn, Ni, Zn and Cd.
Evaluation of selected risk elements removal processes from wastewater in constructed wetlands.
MRÁZKOVÁ, Ivana
The purpose of this bachelor work is to provide a literature survey aimed at the processes responsible for removal of selected risk elements (arsenate, lead, nickel, Merkury, kadmium and manganese) during the wastewater treatment in constructed wetlands. Also, constructed wetlands are compared with conventional treatment plants.
