A bench-scale fluidized-bed bioreactor was operated for over 4 months to characterize the biooxidation of major organic pollutants in coal gasification wastewater obtained from the Morgantown Energy Technology Center. Monohydric phenol was degraded first, followed by more complex phenolics, including polycyclic aromatic hydrocarbons (PAHs). Organic components were assayed by methylene chloride extraction followed by gas chromatography. Genetic capability for degradation of naphthalene by the biofilm was identified by gene probe analysis. Further studies were conducted to determine if the existing biofilm could be enhanced for naphthalene degradation by supplemental inoculation with a microbial culture having good naphthalene-degrading capabilities. The biofilm response was monitored using gene probe techniques. An assessment of wastewater treatment technologies for coal conversion wastewaters was initiated. A bibliography was compiled, arrangements were initiated to collaborate with other investigators doing wastewater treatability studies, and a site visit was made to the Great Plains plant. 201 refs., 3 figs., 5 tabs.
