The activated sludge wastewater treatment process predominantly used in the chemical and steel industries was reviewed to determine the dynamics and control of activated sludge systems treating inhibitory wastes. While this process has the capability to degrade a variety of toxic or inhibitory wastes, the underlying mechanisms are not clear. A variety of issues exist requiring further study: (1) the role of various microorganisms in waste removal and system stability, (2) the mechanisms of inhibitory action at both the level of the primary consumer and at the level of the whole process, (3) the suitability of phenol as a model inhibitory substrate, (4) the appropriateness of using pure culture, CSTR results obtained at relatively high specific growth rates to predict the response of activated sludge systems, (5) the rationalization of microbiological predictions for oligotrophic systems with observations in activated sludge systems, and (6) the development of appropriate monitoring tools for detecting process instabilities. 265 refs., 8 figs., 2 tabs.
