Anaerobic treatment of a biologically inhibitory waste water
A sequence of unit processes consisting of berl-saddle-packed-bed anaerobic reactor and an expanded-bed, granular activated carbon fluidized-bed anaerobic reactor was used for the treatment of a synthetically prepared coal conversion waste water. The waste water, with high concentrations of inhibitory compounds, was fed at three different chemical oxygen demand (COD) concentrations: 1513, 3027, and 7567 mg/L. Excellent removal or organic matter combined with high conversion of COD to methane was achieved. Negligible removal of COD was observed in the packed-bed reactor whereas the expanded-bed GAC reactor was removed in the majority of the organics in the waste water. Ortho- and meta-cresol resisted biodegradation and their toxicity to the anaerobic culture in the GAC reactor was overcome by partial replacement of the granular activated carbon medium in that reactor.
