Abstract
At present, with the economic development and urbanization process accelerated, the use of water resources has been adequate attention to urban water supply enterprises have also felt the increasing pressure. To cope with these difficulties, it is necessary to improve the water supply system of predictability and controllability, mining and the use of automation technology is one of effective means.
Combine the water factory engineering,designed the water factoryfilter pond anti-flush the process and the non level pressure and variance watersupplying system.Return to supervise and control the system to carry on theintroduction towards supervising and control the software Intouch and the place ofhonor machines at the same time. The design of the main use of PLC as the main means of control, the use of a residual flow feedforward + feedback control of the complex, designed a distributed control system.
Makes the realization of automation to more stable water plant up and running, in the use of fewer staff and better case management of the water plant production and safety issues, but also increased the productivity of water plants, improve the water plant economic benefits.
