Biochemical treatment technologies for gas industry wastes

Conference ·
OSTI ID:6249343
Sequential chemical and biological amendments as well as sequential biological processes (e.g. anaerobic-aerobic) may have potential in reducing pollutants present in Gas Industry wastes. Several Town Gas soils have been characterized regarding Polyaromatic Hydrocarbon (PAH) levels and soil particle distributions prior to and following biological treatment. Multivariate statistical analyses have revealed that the presence of biodegradable PAHs such as naphthalene in a sand matrix have significant influence on the effectiveness of biological treatment schemes. Integrated chemical-biological treatment processes have been devised that are effective in achieving extensive PAH degradation, even in soils that are dominated by persistent and normally recalcitrant PAHs. Other research is addressing gas industry wastes contaminated with PCBs. Anaerobic dechlorination has been demonstrated for PCBs present in Aroclor 1242. Sequential anaerobic-aerobic treatment is being evaluated for PCB-laden gas condensate waters and contaminated soils. A focused effort is being directed at testing some of these technologies during field experimentation. A Town Gas soil is being subjected to such a field test this summer using conventional land treatment technology. 2 refs., 8 figs.
