Wastewater treatment involves a large-scale industrial process,featured with the characteristics of dynamics,nonlinearity,multi-variabilities and randomicity.Traditionally wastewater treatment plants much rely on human experience and conventional instrumental monitoring and control,and decentralized processing systems,leading to relatively low efficiency of overall manaegment.Especially when the quantity and quality of inflow fluctuate without certain partents,it is difficult to effectively ensure the holistically stabile and optimal operation and discharge standards of effluents,and is easy to reduce the effective use of energy and resources and cause unnecessary waste in order to safeguard the efllent quality.In recent years,researchers have proposed and apllied the artificial intelligence aided control methods to solve the global control problems of wastewater treatment systems,such as expert systems,artificial neural networks,and data mining.Based on the comprehensive analysis of the status quo of artificial intelligence technologies and their application in wastewater treatment field at domestic and international levels,a distributed intelligent sewage treatment system based on MAS theory is proposed and constructed.The system is divided into senven sub-systems with independent thinking ability by distributing the control tasks.The system uses a specific Agent subsystem to complete the specific control work.Through the communication and coordination among the subsystems of the Agent,the system can realize the intelligent control.At the same time,the ant colony algorithm is introduced into the MAS system by using the bionics related results,and the control decision method based on random disturbance ant colony is designed.The process of improving the ant colony algorithm task is described,control the task allocation function in the system.Finally,through the research of the fuzzy control theory,the ozone aeration agent control system based on the MAS theory is established,and the fuzzy control are used to realize.The ozone aeration agent system is used in the specific control system,and the simulation is analyzed in detail.The system shows strong stability,which proves that the distributed intelligent sewage treatment system based on MAS theory is feasible and adaptive in the actual control process.
