Automatic Measurement of the Inhibitory Effect of Toxic Effluents on Process Microorganisms in Wastewater Treatment

摘要

The microbiological purification of industrial effluents often places high demand on the physiological performance of primary and secondary populations in activated sludges. This particularly applies to combined effluents, originating from different industrial processes, which show frequent fluctuations of effluent composition. Eliminating carbon, nitrogen and phosphorus compounds in parallel during continuous biological purification requires a sensitive steady state equilibrium which may be disturbed by toxic components. The problem of nitrification inhibition is especially delicate since nitrobacteria have low growth rates and therefore a reduced regenerative capacity.
