Stable operation strategy of sewage treatment plant in dry days which based on future sewage treatment capacity forecast
With the development of the city,the operation mode of large drainage facilities tends to be complex.For multi-node inflow sewage plants,the traditional manual scheduling mode is difficult to meet the demand of refined scheduling,and it is difficult to ensure the stability of the sewage treatment capacity.In this paper,taking a large drainage system in Shanghai as an exam-ple,the estimation of future instantaneous sewage treatment capacity is obtained by Kalman-like filtering and Fourier transform on historical and real-time data.At the same time,combining the capacity of each sewage treatment plant and the scale of the storage facilities,the operation strategy of the multi-node inflow sewage treatment plant is formulated to achieve the stable operation in dry days.After applying the operation strategy proposed in this paper,the fluctuation value of the treatment capacity of the sewage treatment plant at the end of the large drainage system has been reduced by more than 80％.Compared with the traditional mode,the stability has been greatly im-proved.
