Therefore, getting water of high quality and establishing a scientific waterquality evaluating system by inclining the focus of investment and tackling technical problems have been a key sector in waterworks’ development. However, the actual monitoring system cannot detect and process water quality parameters and system operating status automatically so that people have to waste more time on collecting sufficient information to make socalled “timely feedback”. In such circumstances, for decreasing operating cost and improving operating efficiency reasons, it is important to study waterworks’ data munication and processing, develop airflotation plant report generation system, and further discuss waterquality evaluating system. This paper makes a brief description of waterworks’ automatic control system and work architecture, and gives a prehensive analysis of the water treatment technological process. On that basis, a waterworks operating data realtime detection and processing system is designed. Main works are shown as the following: (1) To achieve the munication between server and PLC controlling station, based on OPC standards, adopted Client/Server Mode, a server is built by Rslinx from which develop OPC client code can collect system operating data. (2) Based on the original data acquired from purification plant, chlorine dosing room and ammonia dosing room, a program is exploited to analyze and store the parameter of water quality, water volume, drug consumption and power consumption. (3) In the client, designed and developed software, to realize daily, monthly and annual report’s query and output. Moreover, users can check parameter curve tendency chart generated by the program intuitively. (4) According to the sanitary standard for drinking water, the paper analyzes the model of waterquality with BP algorithm, aimed at the algorithm’s defect, present improvement method, and verifies the system through simulation and experiment. The present system has been in a trial run in a certain waterworks in Tianjin. Its successful operating reduces worker’s labor intensity and gives a realtime water quality monitoring, and will be contributory for improving the informationalized level of III waterworks.
