Abstract:

In order to improve the performance of equipment manufacturer and self-control professionals in the scene of processing and solve the problem of efficiency, the CASS(Cyclic Activated Sludge System) process of automatic sewage treatment control system was designed and implemented in  addition to the rem
ote monitoring and maintenance function model. Based on the characteristics of the CASS technology, we developed a set of stable and reliable sewage treatment automatic control system. The upper/lower machine design scheme of the control system was introduced in detail, including network topology structure etc. The bit machine in the process of programming is put forward based on the state transition diagram programming method. DameWare sof
tware is described in detail in the sewage treatment control system to excute the significance of remote monitoring and maintenance function and operation method. Operation result shows that the control system performance is stable and reliable, especially over the design of remote monitoring and main tenance functions effectively which reduces the fault diagnosis and resolution time, meets the design goals and requirements.

Key words: cyclic activated sludge system (CASS) craft, automatic control, state diagram programming, super remote monitoring and maintenance
