Title: Simulation of wastewater treatment processes and possible idea solution for upgrading WWTP Škofja Loka
Abstract: In addition to building new treatment plants in recent years there is also increasingly taking place the upgrading of existing wastewater treatment plants. Need to upgrade is in larger extent because of failing to complie with effluent nutrient limits for parameters, such as nitrogen and phosphorus. One of the sewage facilities where upgrade of the processes for removal of nutrients has not yet been made is the Central Wastewater Treatment Plant Skofja Loka. This thesis has made preliminary studies of upgrade of WWTP Sk. L. by the simulation with a computer program Aquifas. The models are sets of mathematical equations that characterize the process and enable the simulation process. Activated sludge models (ASM) are being presented, of which ASM2d is a part of Aquifas application. As part of identifying possible solution for upgrading an overview of processes and technologies for the removal of nutrients has been done, and among them, as appropriate outline of possible solutions, the A2O process has been selected that I have regarding to the inflow of different parameters to the treatment plant tried to optimize with the program. The results for the effluent obtained from so conceived process and after optimization of various parameters are under regulatory limits. The thesis also presents important issues that need to be considered in upgrading existing facilities, including general selection factors, design and operation factors and the final selection of appropriate technology.
