Control method and system for integration of urban sewage plant and network

The invention discloses a control method and system for integration of an urban sewage plant and a network, and belongs to the technical field of sewage treatment, the method takes'total quantity control and continuous improvement 'as a core concept, and provides an operation method of'platform construction, rainwater and sewage diversion synchronization and plant and network coordination' for an urban drainage system, so that the emission reduction benefit improvement, quality improvement and efficiency improvement of the drainage system are realized. Comprising the following steps: establishing a unified monitoring platform to realize data acquisition, diagnosis and scheduling; a mixed connection ratio evaluation model based on material conservation is established, the mixed connection degree and area are quickly diagnosed, and the rain and sewage diversion efficiency is improved; a linear model based on a comprehensive pollution index total quantity reduction target is established, the maximum hydraulic lo
