The study alternatives village sewer system Crhov
Sakáčová, Monika ; Raček,, Jakub (referee) ; Hluštík, Petr (advisor)
The theme of this diploma thesis is " The study alternatives village sewer system Crhov". The thesis focuses on the design of possible wastewater treatment options with design of the technology for waste water treatment. Four alternatives are proposed - catch up existing sewerage and build an aerobic pond, new sewerage system with a container sewage treatment plant, domestic sewage treatment plant and the existing drainage system and the construction of a sewage treatment plant. In addition to the proposal itself, financial valuation of these variants is an integral part of the work with its own recommendation.

Splňují ryby chované v biologickém rybníku napájeném vodou z ČOV požadavky na hygienickou kvalitu masa?
KAREŠ, Martin
This bachelor thesis focuses on impact analysis of the biological pond on the hygienic quality of the fish flesh. The main aim was to analyse toxic metals, persistent organic pollutants and organoleptic quality in the muscle of common carp (Cyprinus carpio), which was influenced by treated water from the municipal sewage treatment plant (STP). The experimental fish were exposed in biological pond Čežarka supplied by STP treated water and in control pond supplied by water from Blanice river. Toxic metals (Hg, Cd, Pb, As) and persistent organic pollutants (PCB, DDT, HCH, HCB) were analysed in muscle of 4 fish groups exposed for 0, 14, 30 and 90 days. The concentration of toxic metals and POPs were compared with valid hygienic limits for fish meat. An organoleptic evaluation was made at the end of the experiment focusing on the aroma, taste, odd-taste and consistency of fish meat. All measured parameters were in compliance with legislative regulations. Concentration of neither micropollutant exceeded valid hygienic limit. The concentration of observed pollutants in fish muscle after 90 days of exposure showed that the water from sewage disposal plant is not the significant source of analysed substances in the environment. However, the treated water from the STP is significant source of PPCPs, which are not limited for the fish meat by legislative regulations.
