Zhodnocení vývoje koncentrace vybraných parametrů v Hradišťském potoce jako důsledek znečištění MDČOV typu aktivace

Abstract

The diploma thesis deals with the development of the concentration of selected physico - chemical parameters in "Hradišťský stream" as a result of wastewater pollution from a small sewage treatment plant (MDČOV) type of activision. For this purpose, samples of surface water were taken regularly from the six sampling points in the longitudinal profile of the flow, each month between October 2016 and September 2017. The sampling points were selected before and below the outlet of waste water from MDČOV, type of activation. The obtained final results were evaluated according to the current legislation and compared with the permissible pollution of surface waters according to Government Decree No. 401/2015. Subsequently, the quality of the water in the recipient at each evaluated site was determined by inclusion in a specific water quality class according to ČSN 75 7221 Water quality - Classification of surface water quality. The theoretical part deals with basic wastewater distribution, description of physico - chemical parameters.
