Evaluation of the efficiency of the system of dehydration operated landfill of municipal waste

The work discusses the basic issues of protection of the aquatic environment in the context of the operation of the facility, with reduced infrastructure support. Survey, the quality of groundwater and the wastewater during the advanced service in the years 2006-2008 after a period of winter the meltdown, were analysed, including benchmarking, which takes into account the variability in the composition of both the groundwater in-flow opacimeter and outflow and leachate collected in the landfill. In assessing the environment includes the components of the compromised sites, as well as the type, quantity and origin of deposited waste.The detailed analysis of the background of the results of the analyses carried out, requires above all to assess the efficiency of the system for the dehydration of the landfill, with an indication of the solutions for the protection of the aquatic environment in the context of the increase of mass deposited of municipal waste not selectively collected. ...

Analysis of transformations occurring in the active landfill area

A summary of the work concerns the basic issues related to the composition process of bio-waste deposited on the municipal landfill. Study of the landfill gas composition obtained in the representative point was analyzed during the exploi-tation of the landfill in the years 2004 - 2008. During the study the quantity and the quality parameters of deposited waste, conditions of its exploitation and the time of deposition were under consideration. Particular attention was also paid to the 30 % share biodegradable waste and the development of aerobic processes during the operation of the landfill. The composition of the gas has demonstrated the domination of aerobic processes by an oxygen content within the limits of the 4,9 - 9,7 % over anaerobic processes in the downtrend content of methane to 2,3 % and 0 % carbon content. At the end of the article some conclusions concerning mainly an inadequate density of deposited waste which results in an easy oxygen access to the surface layers of the waste. ...

Assessment of the size of selective waste collection for example of the selected settletmnet unit

The goal of the work was an analysis of the waste management system at the municipal level in the context of limitation the amount of unselectively waste collection. At work showed the results of studies that relate to the amount collected selectively and unselectively household waste in the years 2007-2010. On the basis of the analysis carried out and showed that the prevalent cadastre of 67 % share on unselective waste collection. During the analysis period for negative has been recognized to decrease the total quantity of waste collection about 85,73 Mg, including selectively about 28,45 Mg in spite of the increase of the number of inhabitants and residential buildings. Moreover in the household waste management system in the commune have not been stating biodegradable waste pickup with a significant their share of more than 33%. Noted the discrepancy between the quantity of produced waste - 973 Mg and collected one - 269,52 Mg, as well as a decline in the value of the weighting indicator of their accumulation about 18 kg·miesz.-1·rok-1, confirmed the possibility of waste management by the inhabitants themselves due to the nature of the rural commune. ...

THE QUALITY OF THE GROUNDWATER IN AREA OF OPERATION LANDFILL SITE

In the work presented and discussed the results of the study of groundwater in the area of the landfill site, which has been done in the years 2004 - 2008 in three piezometer points. For the analysis were taken into account the value of the reaction, electrolytic conductivity, TOC, Cr + 6, Pb, Cd, Hg, Zn and PAH. The results of the test of groundwater are normative values of Polish Standards, as well as the comparative analysis was taking into account the direction of their flow. The topic of the work was to assess the quality of these waters at the stage of the operation of the municipal landfill site. Tested waters in area of the landfill site was characterized by variability of their composition. In particular, an increase in the content of cadmium has confirmed influence of waste in underground waters on their outflow and on their qualities in result limited proficiency of drainage system of the landfill site. However, increased contents of product of incomplete combustionof organic product on inflow so as well outflow of this water it has exerted relationship with interaction of the effects of anthropogenic. ...

Chemical composition of leachates on exploited landfill site

Results of analyses of underground waters on a municipal landfill site conducted in 2004-2008, prior to leachate cleaning were presented and discussed in the paper. The sewage quality analysis comprised pH, electrolytic conductivity, TOC, Cr+6, Pb, Cd, Cu, Hg, Zn and PAHs. Results of leachate water testing were compared with standard values and subjected to comparative analysis taking into consideration also atmospheric precipitation amount. The aim of the paper was to assess the leachate water quality in conditions of exploited municipal landfill. The analyzed waters were characterized by variability of composition evidenced by increasing pH values, electrolytic conductivity and heavy metal concentrations (Cr, Hg) total organic carbon (TOC) and PAHs, but also by a decline in heavy metal contents (Pb, Cd, Cu and Zn). ...
