Abstract
New paradigm of sustainabe development stands for researchers new requests for developing of new processes and optimization of existent ones. This dictates directed and interdisciplinary linking of scientific enterprises capacities, exchange of experiences and connection with practical work. Prevention access at the environmental protection urgently demands harminized developing and implemented access all over the world. Linkage is needed also because of needs according to complete ascertaminment of circumstances and trends of the quality of components of the environment. We will use complex access for the research work, which will connect development of cleaner technologies for the filed of selected chemical-process industries (process optimization usage of raw material, water and energy, change of dangereus materials with environmental friendly materials, reduction of quantity and dangereus emmissions and wastes); choice indicators for comparative evaluation of alternative technologies of the same quality of products, and improvement of comuter methods for modelling and optimization of processes; integrated manipulation with wastewater and wastes, regenerative procedures pretreated high polluted process waters and wastewaters and recirculation of process waters and introduction of concept "zero waste". Research work on the filed of surface water will be directed to make general strategy for integrated evaluation and for management with pollution sources. Research will contain chemical and ecotoxicological characterization of pollution, field measurements, hydrological studies, and modelling of dilution and decomposition of pollution in the receiving water, evaluation of the impact to the environment and expected evaluation possible reduction measurements. Pollution loading from diffuse sources will be evaluated on the basis of data from the monitoring of surface water quality. At the TIE procedures in sediments fractional procedures for removing of potentional toxic substances will be used. Toxicity tests that show us the influences of present substances to organisms, should be sensitive enough that they perceive low concentrations toxic substances in the environment. We will assess changes in organisms as a consequence of exposure to sublethal concentrations of toxic substances on cell level.We will develop methods for determination of several enzimes activity. We will use organisms from different trophic levels of aquatic ecosystems (bacteria, algae, crayfish, fish), that are firquently esed in the ecotoxicology. Biodegradation of chemicals and wastewater will be determined by different laboratory methods dependant on physical chemical and other conditions. This will be the basis for the judgement of environmental impact assessment and monitorng of effects of different kinds of wastewater treatment. We will develop different measurement techniques for the detection of decomposition metabolites. Operation of wastewater treatment plants with fixed biomass will be optimized by technological patameters monitoring. We will study kinetics and the influence of hydrodynamic conditions on the material transport in biofilm in continuous and sequencing laboratory reactor. Mineralization of sludges from the biological treatment plants in anaerobic and aerobic reactor the main parameters will be accompanied, such as suspended solids, volatile suspended solids, COD, TOC, and qualitative and quantitative biogas production. With simulation of laboratory methods possibility of bioremediation of surface water, underground water and wastes pollution will be monitored. We will keep under review mechanisms of substances transformation with different measurement techniques and try to identify types and environmental properties of intermediates and end products. We will study factors that enable transfer laboratory data to real environment. For better quality of data the method for demonstration of traceability of results to SI units...
Significance for science
Interdisciplinary approach to disabling of pollution of water captured reduction of emissions, optimization and development of new technologies and monitoring of pollution impacts. Results of our research work have been published in international and domestic journals. With this were contributing to wider to development of contemporary points of view and rescuing of introduced problems.
Significance for the country
The contribution for Slovenia is twofold: first, for sustainable socially-economic and cultural development, and second, for technical development. Results of research work were contributing to creating of necessary knowledge for sustainable socially-economic development of Republic of Slovenia, because we considered characteristic and most burning problems of industrial and social practice from field protections of environment in Slovenia and rise of competitiveness. In our contributions in Slovenia we were warning to the development of system of treatments with environment, where waste substances should be minimized, useful substances recycle maximally, entire process should be energetically optimized. Results of research work have also contributed to technological development of Slovenian industry and public utility sector, because they were guided to integration of new technical and conceptual environmental protection solutions to basic production service technological processes. We have developed sequencing system for wastewater treatment, which was also patented. On the basis of this patent numerous wastewater treatment plants were built (10 municipal wastewater treatment plants and one industrial wastewater treatment plant). With our research work we also contributed to keeping of natural wealth of Republic of Slovenia, also her raw material sources, natural stocks (above all water) and clean environment.
