Water flow separate discharge method for urban pipeline network with river, rain and sewage mixed flow

The present invention relates to a water partial mass emissions mixed urban river storm sewage pipe network, comprising the steps of: providing the original flow line at the outlet of the drain pipe; bypass duct section is provided near the drainage network of the monitored area, the monitored area set the water quality monitoring sensor; a monitor and a sensor connected to the water quality data to the digital data processor; data processing processor, parameters of river water is formed, then compared with the shunt threshold, the control means determining the selection of the diversion of the water flow from the manifold pipe rainwater drain pipe or sewer discharge. Identified by the methods described above may be automatically split press Water: rainwater security compliance river water quality management target by rainwater discharge pipe into the channel, on the contrary, polluted water into the sewer. Thus, to protect the viability of the river, the river drainage capacity to play, in harmony with the river ecological environment; urban river water quality, water recycling, with remote monitoring and control capabilities.
