Originální abstrakt
Thermal treatment of waste (municipal, hazardous, biological) is used as an integral part of integrated waste management throughout Europe, because it represents safer and more effective technology of waste disposal in comparison with landfill. To minimize the impact of this technology on the environment, it is necessary to remove harmful and undesirable compounds which are being formed during the incineration process. The pollutants include fine solid particles, acid gases, heavy metals and their compounds in gaseous phase, dibenzodioxins and dibenzofurans (PCDD/F), etc. Limit concentration values of these contaminants in the flue gas released into the atmosphere are strictly defined by the valid Czech and EU environmental regulations. Therefore, several devices have to be integrated in the flue gas cleaning unit in order to reduce pollutants concentration. These devices employ a range of processes that are based on various physical and chemical principles. In industrial waste incineration plant were carried out some technical measurements of basic characteristics of flue gas in order to create the total balances of harmful substances, including heavy metals and selected gaseous components. For this purpose such individual measurement points (Figure 1) were chosen which enable to evaluate the removing efficiency of monitored components in particular equipments for flue gas cleaning. Different operating parameters of incineration plant were complex recorded during individual measurements. On the base of analyses of the input and output streams in the incineration plant (the treated waste, slag, fly ash, flue gas, waste water, etc.) was made a mass balance of heavy metals and their distribution into the combustion products. The measured data are in good agreement with the values reported by Cernushi et al. that were collected in a municipal solid waste incineration plant. It was confirmed that if mercury is present at the treated waste, then even very efficient fabric filters are not sufficient for satisfactory removal of Hg, because the main part of mercury remains vaporised in the flue gas entering the absorption and the adsorption cleaning sections.
