Applied Research, Monitoring And Data Analysis Systems In The Sewage Treatment Plant

In this paper, it introduced firstly the essentiality and development of sewage treatment, the development of automatic control in sewage treatment, guideline of sewage, model process, and the Bardenpho/Carrousel process of the Kunming sewage treatment plant emphatically. Then it introduced the development, character, kind of the computer supervisory control, and introduced specially the character and constitutes of SIMATIC WinCC. And it pointed out that sewage treatment should use computer supervisory control as the reason of mass and complex control variable and its importance to people's body and mind. And more, the use of supervisory control is a trend, and the SIMATIC WinCC is chiefly.Then it designed the supervisory control system, navigation interface for total supervisory control, process interface for process supervisory control, alarm interface for alarm supervisory control, trend interface for trend supervisory control, report interface for report display and print, and landing interface for different authorization to different user. It shows every design picture and run picture for every interface. And it uses the power of SIMATIC WinCC, and bring more convenience to supervisor sewage treatment at the same time.Because there isn't using of data analyze, and this is a disadvantageous for better supervisory control, more extensive monitor colony, more accurate decision-making, it pointed out sewage treatment plant should integrate supervisory control system and data analyze system, and get a timing and humanism supervisory and control and data analyze system. The Excel is ~~seTectect as data analyze software. Excel is from Microsoft Office, and easy to operate. And the junction of supervisory control system and data analyze system should be solved firstly. It presented three kind methods for different situation.Then it developed the data analyze system in sewage treatment. It designed the navigation picture, and buttons to enter different function, such as data obtain, pole analyze, curve analyze, statistic analyze, data rendering. These function is enough to sewage treatment. So we can monitor the variables in sewage treatment process, find abnormity, and operate accordingly ormake precise decision.Finally the success and shortage of this paper is summed up.
