Abstract: Through analyzing the water purification process which consists of factors such as changes in turbidity, PH value of the lag, disturbance, and system dynamic of complex issues, in order to improve water quality and ensure purified water up to the national standards, the basic control correlations in the process of water purification are found, established by the turbidity and the PH value of the two main causal chain structure consisting of interconnected decentralized control model. According to the model this paper designs the chain pre- estimation algorithm and chain system control algorithm. It makes system simulated. Simulation results show that the system has good stability and anti-jamming capability.

Key words: water purification, chain-system, prediction, modeling
