摘要
A control equation was developed for reducing the variability of effluent total soluble phosphorus in a 200 MGD (8.76 mJS-1 chemico- biological process at Milwaukee, Wisconsin, U.S.A. A statistically adequate multivariate time series model. Autoregressive Moving Average Vector model (ARMAV) was obtained using the operating data. This model describes the dynamic and stochastic characteristics of the process in relation to total soluble phosphorus removal process. The control equation derived from the model is based on the minimum mean square error (MMSE) strategy, a feedforward, feedback control scheme. The result of implemeting the control scheme will be approximately a 60% reduction in the variability (variance) of effluent total soluble phosphorus when compared to the existing feedforward control scheme at the treatment plant. Field testings have yet to be performed to validate the analysis. © 1979.
