Most of used mineral and organic sorbents are hazardous waste and, therefore, in accordance with actual law regulations must be converted thermally or deposited in the special landfill for hazardous waste. The optimal solution would be sorption materials that could be used repeatedly, without the need for costly and cumbersome lanfilling. Sorbents, which due to their properties could be used repeatedly, are MSW composts generated from mixed or only organic municipal waste. In this study we have investigated the rate of degradation of motor oil on MSW waste composts with microflora pre-adapted for use of oil products as source of carbon. Comparison of degradation efficiency, was calculated in comparison to the commercial sorbents. During the experiment the total amount of synthetic motor oil and individual n-alkanes with carbon chain length from C22 to C40. During the experiment, there were observed more intensive oil degradation processes on waste composts in comparison to commercial sorbents. Microflora which use n-alkanes as a carbon source, ensured quick (noted after the first month of the experiment), reduction of the amount of hydrocarbons contamination in the samples, and thus the possibility of re-use of compost as a sorbent. The observed rapid degradation process, indicates the direction ...
This paper presents the research results of pollution level in Stobrawa river. The research was carried out on 19,5 km of the river in six test points: from the cross-section of the planned Kluczbork storage reservoir (point St.1) to the river source (point St.6). The test was carried out between November 2006 and October 2007. In the tested samples following compounds were determined: NO3-, NO2-, NH4+, PO43-, Ptot., BOD5, DO, TSS, water temperature, water reaction and elektro-lytic conductivity. Beside water quality tests, the hydrometric measurements were carried out. The paper also presents Stobrawa river quality valuation. The valua-tion of eutrophication of the Stobrawa river has been presented as well and it has been determined if the water is prone to nitrogen compounds pollution from agri-culture. The Stobrawa river catchment area has been valuated taking into consid-eration the flowing matter into the body water.The test has shown vast pollution of water flowing into the Kluczbork water body. Subsequently it may negatively influence the water quality in the body of water in terms of its future possible water retention. It has been shown that the familiarity of the profile of water quality indica-tors changeability is crucial while taking decision whether to build ...
