EVALUATION OF WASTEWATER TREATMENT EFFICIENCY IN WOLBROM

The study was conducted to assess the effectiveness of wastewater treatment at the municipal wastewater treatment plant in Wolbrom, to which predominantly domestic wastewater and industrial sewage flow. The assessment was made based on the analysis of the physical and chemical research results of raw and treated wastewater. The research was carried out in the period from January 2014 to December 2014. To perform the analysis of the treatment plant efficiency, four indicators of wastewater pollutants such as BOD5, COD, total nitrogen and total phosphorus were selected for further investigation. For each of the indicators degrees of reduction and coefficients of treatment plant operational reliability were calculated. The calculated degrees of reduction for each of the indicators were high and amounted to 99.0% for BOD5, 95.2% for COD, 91.0% for total nitrogen and 91.6%. for total phosphorus. These results prove the effective reduction in the amount of pollutants. The determined coefficients of treatment plant operational reliability were at a low level: BOD5 - 0.27, COD - 0.44, total nitrogen - 0.33 and total phosphorus - 0.53. The conducted analyses prove the effective operation of the treatment plant, which was confirmed by high efficiency of pollutants removal. ...

ANALYSIS OF MORPHOLOGICAL COMPOSITION OF WASTES DEPOSITED ON ILLEGAL DUMPING SITES LOCATED IN THE AREA OF OLSZTYN DISTRICT

Generated wastes require space and financial outlays on their proper storage and processing, whereas the lack of means usually leads to depositing wastes in places not meant for this purpose. Illegal dumping sites still emerge, despite introducing in Poland the obligatory (common) fee for collection and management of wastes and the obligatory establishing the Selective Waste Collection Points in each district. The aim of the work was conducting a detailed inventory of illegal dumping sites in the area of Olsztyn district (situated in the Silesia province, on the Krakow-Częstochowa Upland) and indicting the morphological composition of the wastes deposited in these places. The paper presents a detailed analysis of the morphological composition of illegal landfill sites situated in the analyzed district. The investigations located 28 illegal dumping sites, despite the fact that a Selective Municipal Waste Collection Point operates in the district area. The analysis of location, area, mass and composition of the wastes was conducted for each illegal landfill, according to the methodology developed for this purpose. Over a half of the illegal dumping sites was situated in the forest and on 4 of them the estimated mass of dumped waste exceeded 1Mg. Debris constitutes the highest proportion (21.8%) ...

THE ROLE OF INFRASTRUCTURE IN SUSTAINABLE DEVELOPMENT OF PROVINCES - COMPARATIVE ANALYSIS

Sustainable development consists in integrating political, economic and social activities while maintaining natural balance and durability of basic natural processes in order to guarantee the possibility of satisfying the basic needs of individual communities or citizens of contemporary and future generations. The paper presents the research results on the impact of selected elements of technical infrastructure on the level of sustainable development of provinces. Both the level of sustainable development and the quality of infrastructure were defined in the form of synthetic indicators.Infrastructure was proved to be the factor affecting the sustainability of development; however, it did not have the same impact on all four domains of sustainable development. It was found that the infrastructure may have a negative effect on sustainable development in the natural (environmental) domain. ...

USE OF RAPID IMPACT ASSESSMENT MATRIX METHOD IN THE ENVIRONMENTAL IMPACT ASSESSMENT OF MUNICIPAL SOLID WASTE COLLECTION POINTS

The duty of each municipality in Poland is to set up a stationary Municipal Solid Waste Collection Points (MSWCP). These facilities are a new element of municipal solid waste management system, known in European countries as: "household waste recycling center". The lack of this type of municipal solid waste management infrastructure in many Polish communes or the existence of MSWCPs in the mobile version contributes to the emergence of wild dumps, and also don't allow the increase of the levels of recycling and reuse of some groups of waste.The environmental impact assessment of five existing MSWCPs in one of the poviats of the Świętokrzyskie Voivodeship was compared in article. The location, functioning and equipment of these facilities were assessed. The RIAM (Rapid Impact Assessment Matrix) method was used for the environmental impact analysis. From among the analyzed MSWCPs, two received a positive assessment, while 3 objects should be close down or completely modernized. ...

THERMOGRAPHIC EVALUATION OF CaO ADDITIVE ON THE PROCESS OF WASTE HYGIENIZATION

Municipal Solid Waste (MSW) is the mixture of many waste types, including organic waste (garden and park waste, food and kitchen waste, paper and cardboard etc.). Such waste creates a living environment for various microorganism species, many of which are known as pathogenic. The presence of microorganisms in favorable conditions (pH, organic matter content, carbon content, moisture, appropriate granulation) leads to decomposing of organic matter, which is accompanied by an increase in temperature. Microorganisms in waste pose a serious risk for staff operating at waste treatment plants. Moreover, heat released by their activity may cause a fire in waste storage facilities. Therefore, it is necessary to search for methods of waste stabilization and hygienization. The most commonly applied technology for waste stabilization is its processing in Mechanical Biological Treatment (MBT) plants. Such treatment is capital- and time-consuming, however. Waste liming can become an alternative method for stabilization and hygienization of waste. Lime addition is one of the oldest method known by humans for hygienization of certain waste materials, such as animal waste. Currently, liming is applied in sewage sludge treatment as one of the initial operations and is necessary for further sludge management processes. The aim of the research ...

AN ANALYSIS OF THE DEVELOPMENT OF TECHNICAL INFRASTRUCTURE IN THE SOUTH-EAST OF POLAND

In this paper was analyzed selected components of technical infrastructure functioning in rural areas of the Malopolska, Świętokrzyskie and Podkarpackie Voivodships. The level of equipping rural areas with specified infrastructure elements was evaluated in the form of density and availability of infrastructure components. The work has been specified the rate of change in the analyzed indicators. In each of the provinces was separated 4, homogeneous groups of municipalities due to the level of infrastructure and standard of living. The lack of consistency in the level of the dynamics of the development of infrastructure with the dynamics of the percentage of residents using the equipment was noted. A positive phenomenon is that the development of the sewage system in all three voivodships has a higher average rate than the average rate of the development of the water supply system. This is particularly important due to the significant underdevelopment of the sewage system in relation to the water supply system ...
