The Application Of Monitoring Configuration System In Sewage Sreatment Plant

By the research on the transformation of Shengli oil field waster water treatment branch , an OPC-based configuration system was established. The thesis describes the automatic monitoring system and feature of the whole sewage treatment plant. Focuses on the process of automatic control system of configuration. Learned the technology of the configuration software ; especially the King view of OPC configuration technology. understand and master the fundamentals of OPC technology.This thesis approximate the PH control problem to the The sour alkali neutralizes reaction problem. According to the inherent nonlinear characteristics of the acid-alkali titration curve, a PID control algorithm is carried on in the process. A PID control algorithm with three segment nonlinear variable gain is investigated to develop the PID control algorithm. In addition, an advanced control algorithm including a fuzzy control algorithm, a fuzzy control algorithm with integration module(IFC) and a model reference nonlinear control (MRNC)algorithm are investigated and carried on in the process . The simulated results of these control algorithms show that intelligent control algorithm is more advantage than PID control algorithm and a perfect effect is obtained. This lays the fundament to implement the PH control strategy.By running the test in actual production, the configuration system achieved very good results.
