- Abstract
At present, operating most wastewater treatment plants (WWTP) in China typically relies on experiences of managers, that is, fuzzy control. However, sewage water quality fluctuates and is frequently unstable given the intensified modernization. Fuzzy control cannot satisfy the requirements of microbial growth during sewage treatment. Thus, a mathematical model is required to realize the intelligent control of sewage treatment plant, thereby providing real-time and accurate environmental conditions and process conditions suitable for microbial growth. Simulation and control based on the model is an effective method for achieving this goal. The mechanism model can simulate a biological reaction process in complex biochemical systems, predict the water quality of sewage treatment plant, and analyze process operation. This model also aims to guide the operation and management of sewage plants, thereby attaining the optimal design of WWTPs and operation of optimization. Fully coupled activated sludge model no. 3 (FCASM3) is a microscopic mechanism model for removing nutrients in an activated sludge system. FCASM3 can simulate the quality of effluent water well; thus, it can be used in upgrading and reconstruction. An FCASM3 model was used to simulate A+A2/O process in Hangzhou Western WWTP in this study. Our scope includes monitoring the quality of influent and analyzing a model ingredient and predicting water quality of effluent by using FCASM3. The influents and effluents of the WWTP were used to reexamine the results for FCASM3, thereby showing that the results applied to Hangzhou Western WWTP. Orthogonal experiments were conducted on the basis of dissolved oxygen and activated sludge and mixed liquid return ratios. The FCASM3 model was used to simulate the optimal process parameters. Simulation results showed that the optimal operating parameters of Hangzhou Western WWTP are a sludge return rate of 75%, mixed liquor returning flow rate of 100%, and oxygen transmit velocity KLa is 50 d−1.
