Abstract

The apparent values of substance pollution in the sewer network of the sewerage system is fully dependent on root and amount of substance pollution emitted into the sewerage by causers of pollution of sewered out and urbanized unit, thereby they influence the system of water pollution control and the final values of concentrations of pollution of emitted waters into surface waters. With the trend of decreasing water demand and also decreasing production of wastewater - in comparison with increase of number of population that are attached to sewerage - it comes to interaction of particular elements of pollution in the sewer network, thereby to efficiency during their treatment. The increase of rain water is no small part in the substance balance of wastewater in the sewer network. Within the thesis the imports of pollutants were under review into waste-waters during using of the washing-up machines and affecting of water discharge-quality by the selected washing-up liquids. Wastewaters emitted into the sewerage for public need can be descharged into the sewerage for public need only according to drainline of relevant sewerage systém that assigns the maximum permissible degree of emitted wastewaters into this sewerage. This thesis deals with substance pollution dynamics in the sewer network discharged out on the Central waste water treatment plant in Ostrava-Přívoz and with their causers in the sequence on the allowed limits of pollution of emitted wastewaters into the sewerage for public need and on the system of wastewater treatment in the urban area of corporate town Ostrava.
