【Abstract】 Daily influent quantity forecasting plays an important role in the design and operation of a sewage treatment plant. Based on the study of effects of weather factors and special events on the influent quantity, daily periodicity of hourly variation of the influent quantity is given a full consideration. The forecast method of daily periodicity of the influent quantity is presented, and back propagation (BP) model and calculation method are set up. The data from an existing sewage treatment plant was employed to forecast the daily inflow and the result shows that this method is effective.更多还原
