An optimal control strategy for sewage pumping station discharging network system is put forward.The intelligent control-drainage algorithm based on energy and pollution minimizing is presented. Through checking the sewage flow of the district and controlling sewage pumping flux of the pumping station, the flux of pumping station and discharging network is automatically adjusted and the flux of each pumping station and pipe is optimally distributed. The flow is discharged as best distance and unit is guaranteed operated in high efficiency area for promoting saving-electricity ratio. At the same time, multi-parameters control for water level and flux of pumping station and sewage network is realized to avoid water overflow from nozzle and collecting well.The control strategy based on genetic fuzzy controller VVVF for single pumping station is presented. VVVF saving-electricity theory combined with circumstances of sewage pumping station is discussed, based on energy and pollution minimizing. The design of genetic fuzzy controller is introduced and the project with genetic algorithm control unit committing is proposed and the sewage pumping station controlling project of genetic fuzzy controller VVVF is proposed.This control strategy has been proved to have good application and referenced with simulating calculation. Combining of the method proposed in this article applying for pumping station is more advanced than the traditional method with constant rate. Water level can keep aimed water level, so best operation state of pumping station in which flux in is equal with flux Out ~5 realized. It could achieve the double-optimal control goal of energy and pollution minimizing.
