Abstract
Cílem práce bylo posouzení vlivu odtoku z čistírny odpadních vod na krasový tok. Studie byla provedena v severní části CHKO Moravský kras a posuzuje vliv ČOV Ostrov u Macochy na jeskynní systém Lopačské propadání. V rámci práce byl proveden půlroční monitoring, který spočíval v odběru vzorků vody vždy jednou za čtrnáct dní. Celkově bylo provedeno 13 odběrů ze 7 odběrných míst. V místě odběru bylo vždy provedeno měření průtoku, teploty, konduktivity, koncentrace kyslíku a hodnota pH. V odebraných vzorcích vody byl následně stanoven obsah nerozpuštěných látek, CHSKCr, BSK5, N-NH4, N-NO2, N-NO3, NKj a Pcelk. Z naměřených hodnot byla zjištěna změna parametrů na jednotlivých odběrných místech v čase a dále po délce toku. Hodnoty odtoků z ČOV byly porovnány s emisními standardy pro vypouštění do povrchových vod a parametry vodních toků byly porovnány s normami environmentální kvality. Dle zjištěných výsledků není prokázáno negativní ovlivnění vodního toku sledovanou ČOV. Největšími problémy jsou: - jednotná kanalizace, zrealizovaná po výstavbě ČOV Ostrov u Macochy, která je dimenzovaná na splaškovou kanalizaci - vysoké koncentrace celkového fosforu na odtoku z ČOV - špatná kvalita toku již před zaústěním odtoku z ČOV
The aim of this thesis is to assess the impact of water outflow from wastewater treatment plant on karst rivers. The study was done in the northern area of Moravský kras protected landscape, where the impact of WWTP Ostrov u Macochy on a cave system Lopačské propadání was studied. As a part of this study a half-year monitoring was carried out, which consisted of water sampling every two weeks. In total, 13 water samples were taken from 7 sampling points. Moreover, flow rate, temperature, conductivity, oxygen concentration and pH were measured at the sampling point. Afterwards, the content of undissolved solids, COD, BOD, N-NH4+, N-NO2-, N-NO3-, NKi and total phosphorus were determined in the samples. The change of parameters in time on the sampling points and further along the flow of the river was evaluated from the measured values. The outflow values from waste water treatment plants were compared with the emission limits for surface waters and the values of river water parameters were compared with the environmental quality standards. It wasn’t proven that the outflow from the observed waste water treatment plant is negatively influencing the water stream. The most serious problems are: -The WWTP was designed for treatment of sewage from Ostrov u Macochy, which involved separate sanitary and storm sewers. After finishing the WWTP, a uniform sewer was built. -High concentration of total phosphorus on the outflow from WWTP. -Poor quality of Lopač brook water already before the outflow vent from WWTP.
