Abstract

The aim of the bachelor thesis is to evaluate the reconstruction of mechanical-biological wastewater treatment plant Jablunkov carried out in 2019. The subject of this reconstruction was to increase the projected WWTP capacity from the existing 8000 PE to 9980 PE, increase the amount of air supplied to activation tanks to increase nitrification efficiency and installation a new sludge dewatering units. As part of the modification of the technology, a new gravel trap was built, incl. lifting equipment, to modify the grease and sand trap, to add aeration elements to the activation tanks, to modify existing blowers, incl. blowers, and last but not least the laying of new air supply pipes to the activation tanks. Part of the bachelor thesis is the evaluation of the monitored parameters of the quality of discharged treated wastewater, the amount of oxygen supplied to the nitrification process and the results of sludge dewatering before and after reconstructionincluding evaluation of electrical consumption. The diploma work also evaluated the impact of the reconstruction of rough pre-treatment on the amount of mined waste and reducing the complexity of handling for COV operator.
