This article shows the situation in the range of cooperation between the since sphere and economy. Largely the low level of innovations in polish companies is because of little scale of cooperation with colleges and research and development units. Research made shows, that the traders can reach the results of research and development units work, mainly by the internet. Article shows also the benefits, that this cooperation can bring.
In this article author points important aspect of the company environment analysis as a source of information for making decisions, what is the key in strategic management. Author presents the results of research in the scope of environment analysis activities and possibility of the raise of qualifications in this scope in companies from the Zachodniopomorskie province.
Aim of the study Adaptation of MBBR technology for the treatment of highly degraded waters in small water reservoirs. Investigation of the effectiveness of organic pollutants treatment in waters with highly polluted (or easily biodegradable) municipal sewage. Checking the effectiveness of nutrient removal during the process of cleaning this type of pollutants. Material and methods The study was conducted in laboratory conditions on a semi-technical scale. Diluted municipal sewage was treated in order to determine purification efficiency for each laboratory stand. The experiments were carried out in 4 research stands (volume of wastewater in each tank amounted to 1000 L), whereas each was equipped with a MBBR bioreactor with a moving bed (biofilm carriers). The physicochemical parameters of pH, redox, and oxygen concentration were examined, and laboratory analyses were performed to indicate changes in COD, BOD5, and selected forms of NH4 and PO4. On the basis of the obtained results, the effectiveness of the wastewater treatment was demonstrated, and the hydraulic parameters of the installation were modelled. Results and conclusions The results of experimental work indicate a significant effectiveness of the process of purifying and removing nutrients in MBBR installations. After designing a suitable floating platform, it will be possible to introduce such installations into degraded water reservoirs for their purification.
