Vyhodnocení rekonstrukce ČOV v Krnově se zaměřením na kalové hospodářství

Abstract

This Diploma Work deals with the reconstruction of the Wastewater Treatment Plant in Krnov and with its aim to sludge economy. In the preliminary part there is general information about sludge economy of wastewater treatment plants including the basic terminology. This part is followed by the description of theoretical principles of the suspension separation. The theoretical part is linked with both, the description of the Wastewater Treatment Plant in Krnov before the reconstruction and the description of it after the reconstruction (2010 – 2011). In the next part there is the description of the realisation and monitoring of the chosen technological solution with its approach to sludge economy and sludge dewatering. Also the results of both flocculant types are recorded there, too. The results of the laboratory tests with the flocculant are analysed in this work. Finally the best type of the flocculant, which is suitable for Wastewater Treatment Plant´s needs in Krnov, is suggested.
