Abstract

This bachelor thesis deals with the issue of wastewater treatment. The theoretical part mentions various types of wastewater and describes the process of wastewater treatment, which is used specifically in the wastewater treatment plant in Holasovice. This work also mentions the individual parts of this wastewater treatment plant and their parameters. The aim of this work was to monitor the parameters of wastewater pollution, which were treated by this wastewater treatment plant in the period 2019-2020. The monitored indicators were – biochemical oxygen demand in 5 days (BOD5), chemical oxygen demand determined by potassium dichromate (CODCr), total undissolved substances (TUS) and ammoniacal nitrogen (N-NH4). These monitored values were used to evaluate the effectiveness of pollution removal and subsequent comparison with current legislation.
