本研究的主要目的是分析在迁地反应器中模拟的Belchatow褐煤、Ziemowit和Bobrek煤矿硬煤的地下煤气化（UCG）实验中产生的废水参数。UCG废水中含有高浓度的无机（如氨氮、亚硝酸盐、氯化物、游离和结合的氰化物、硫酸盐和微量元素：As、B、Cr、Zn、Al、Cd、Co、Mn、Cu、Mo、Ni、Pb、Hg、Se、Ti、Fe）和有机（如酚类物质、苯及其烷基衍生物和多环芳烃）污染物，可能对地下水构成潜在威胁。主成分分析和层次聚类分析可以有效地探究褐煤和硬煤氧气化过程中产生的样品在特定组分的数量和浓度上的异同。褐煤气化过程产生的废水总量高于硬煤气化实验产生的废水总量。褐煤气化废水中苊、菲、蒽、荧光蒽和芘的含量最高，而硬煤气化废水中亚硝酸盐、As、Cr、Cu、苯、甲苯、二甲苯、苯并(a)蒽、芘、苯并(b)荧光蒽、苯并(k)荧光蒽和苯并(a)芘的含量相对较高。
The main goal of the study was the analysis of the parameters of wastewater generated during the ex situ underground coal gasification (UCG) experiments on lignite from Belchatow, and hard coal from Ziemowit and Bobrek coal mines, simulated in the ex situ reactor. The UCG wastewater may pose a potential threat to the groundwater since it contains high concentrations of inorganic (i.e., ammonia nitrogen, nitrites, chlorides, free and bound cyanides, sulfates and trace elements: As, B, Cr, Zn, Al, Cd, Co, Mn, Cu, Mo, Ni, Pb, Hg, Se, Ti, Fe) and organic (i.e., phenolics, benzene and their alkyl derivatives, and polycyclic aromatic hydrocarbons) contaminants. The principal component analysis and hierarchical clustering analysis enabled to effectively explore the similarities and dissimilarities between the samples generated in lignite and hard coal oxygen gasification process in terms of the amounts and concentrations of particular components. The total amount of wastewater produced in lignite gasification process was higher than the amount generated in hard coal gasification experiments. The lignite gasification wastewater was also characterized by the highest contents of acenaphthene, phenanthrene, anthracene, fluoranthene, and pyrene, whereas hard coal gasification wastewater was characterized by relatively higher concentrations of nitrites, As, Cr, Cu, benzene, toluene, xylene, benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, and benzo(a)pyrene.
