Emisja zanieczyszczeń z procesu grafityzacji elektrod węglowych w piecach LWG (Castnera). Część 1. Wybrane substancje gazowe
(Wydawnictwa AGH, 2005) Mazur, Marian ; Oleniacz, Robert ; Bogacki, Marek ; Szczygłowski, Przemysław
In the paper the results of measurements of quantity pollutants originated and emitted to air from resistor stoves of type LWG (Castner) were introduced. The investigation was carried out during graphite process of coal electrodes, until moment of end of ventilation the stove across applied installations of cleaning of cool gases (catalytic burning and the wet desulphurization). The measurement results of $CO$, $CO_{2}$, $HC+H_{2}$, $SO_{2}$, $H_{2}S$, $CS_{2}$, $NO$, $NO_{2}$, $NH_{3}$ as well as chosen hydrocarbons $(C_{1}-C_{6})$ and aromatic hydrocarbons (BTX) were presented. In result of conducted investigations was qualified courses of changeability of concentrations in gases these substances before and for the cleaning system. The effectiveness of the substance removing from exhaust gases was estimated as well as range of occurrence of their maximum release. The additional investigations of catalytic burning showed, that this process causes the formation of the additional quantities of benzene.
Zanieczyszczenie chromem Jeziora Rożnowskiego
(Wydawnictwa AGH, 2005) Helios-Rybicka, Edeltrauda; Kuźniakowska, Magdalena; Gruszecka-Kosowska, Agnieszka
Roznowskie Lake is the reservoir of the accumulative contaminants, which are dumped into the waters of Dunajec and Poprad River. The aim of the researches was to define the level of contamination with chromium sediments and water in the Roznowskie Lake. This element was chosen for investigation, due to great spread of tannery works on this area of the river basin, that can be the source of the chromium. From the whole area of the lake it was taken 42 bottom sediment samples and 42 water samples with the suspended matter. Laboratory analyses showed, that there is very Iow concentration of the chromium in water and also in bottom sediments and suspended matter. Comparing the results with actual (valid) Polish Law connected with (related to) drinking waters, it can be said that with contamination of Cr, waters from Roznowskie Lake, belong to first class of cleanness. Sediments output by the processes of desludging of the water reservoirs, can be used for recultivation of soils, while the concentration of the Cr in none of the sediment samples overpass the permissible level of 200 mg/kg dry mass. Polish Legal Acts do not take under consideration defining the contamination level of pollutants in the suspended matter. According to German LAWA classification, constituents of the Roznowskie Lake with contamination of Cr, belong to the first class of cleanness (non polluted).
System gospodarowania olejami odpadowymi na terenie województwa podkarpackiego
(Wydawnictwa AGH, 2005) Przewoźnik, Dorota; Grzesik, Katarzyna
The current situation in waste oil management system in Podkarpacki region was presented in the article. The volume of produced waste oils along with perspective future figures till the year 2014 were taken into account. The collection system of waste oils as well as the technology of oil recycling were described in detail. Consortium of Waste Oils is one of the most resiliently functioning Polish organizations in respect of a collection and recycling of used oils. This organization was established on the basis of Jedlicze Refinery (Podkarpacki region). The Consortium elaborated a concept of nationwide integrated network of collection and recycling of waste oils. This concept assumes a cooperation with local authorities. A collection of oils from dispersed and small sources can be implemented on the level of gmina (lowest level of local authority in Poland) in so-called Hazardous Waste Collection Points. Oil Refinery in Jedlicze operates an installation designed for initial refining and distilling waste oils. Collected oils are subject of refining through decantation process followed by distilling. Re-refining process is the next step of oil recycling. A modern process of waste oils recycling, complying with obligatory procedures of waste treatment is applied in Jedlicze Refinery. Recycling of waste oils results in many benefits - ecological, energetic, economic and fuel ones.
Symptomy rozwoju procesu glebotwórczego pod młodymi zalesieniami rekultywacyjnymi na spągu wyrobiska Kopalni Piasku »Szczakowa«
(Wydawnictwa AGH, 2005) Kowalik, Stanisław; Wójcik, Jerzy
On the reclaimed floor of the old working of the Sand Mine »Szczakowa« the studies on chemical properties of soils under 10 years old larch (Larix europaea) and pine (Pinus silvestris) forest were carried out. Similar symptoms of the differentiation of the morphological picture of both initial soils (made of loose sand) were detected. Both under larch and pine about 1-cm thick layer of overburden humus were found as well as a very weakly marked initial humus level. Close to surface mineral layer (0-10 cm) of both soils were characterized with much higher than other content of organic C and N total. To the depth of 30 cm also big acidification of ground was found, compared to the initial state and at present, compared to deeper layers. Both soils are characterized by very Iow content of nutrients, small capacity of sorption complex, with a Iow degree of saturation with alkali. Despite very unfavourable properties of ground both larch and pine have high growth rate, which indicates a significant role of shallowly situated (0.7-0.9 m) layer of ground water.
Zastosowanie modelu Calmet/Calpuff do obliczeń poziomu stężeń zanieczyszczeń pochodzących z wysokich emitorów punktowych
(Wydawnictwa AGH, 2005) Szczygłowski, Przemysław; Mazur, Marian
The presented research material is the attempt of application Calmet/ Calpuff model to calculating pollutant concentration from high point sources. In the paper Gauss puff model was generally described. There was also calculated dispersion of air pollutant $(SO_{2})$ in atmosphere from source with constant and variable emissions.
