Summary: The investigation of biodegradation of toxic organic compounds in waste water originating from chemical industry was carried out using mixed culture of bacteria and yeasts. Three group of waste waters were investigated: The first group of waste waters were loaded with the compounds of the structure as: phenols, naphthalene, anthracene and naphthalensulfonic acids. The second group were the structures of polyaromatic hydrocarbon, cyanides, thiocyanates and lignosulfonates and the third group were waste waters loaded with high concentration of nitrogen and phosphorus. The microorganisms were selected and defined as monocultures and mixed culture of bacteria and yeasts with high enzymatic activity for the biodegradation of mentioned compounds. During the biodegradation these compounds in waste waters, the processes of detoxification and simultaneous nitrification and denitrification took place. The parameters of biodegradation of these processes were determined in lab-scale on the defined substrates as well as on the original waste waters. For industrial scale were prepared the great amount of biomass as "starter culture", which were applied for waste waters from the production of phenol, coke and antibiotics as well as for the elimination of nitrogen from municipal waste waters. On the basis of these results of the investigation was developed and applied a new technology for the treatment of municipal and industrial waste waters called "Technology of injection". This technology was applied for the treatment of waste waters from the production of phenol and coke.

Keywords: Biodegradation, Selected mixed culture, Starter culture, Detoxification, Simultaneous nitrification and denitrification

Research goals: Goals and expected results: The results of lab experiment could be applly in large scale in the industry for the treatment of waste waters. The achieved results in lab scale are the aim to attain the quality of the effluent on the level of european standards of quality.
