Control simulation method for waste water treatment process as well as simulation method thereof

Abstract

The invention provides a control simulation method for a wastewater treatment process. The data base of the wastewater treatment process is established through a parameter sensor and the data collection system of the wastewater treatment process. Firstly, 100 to 150 days of open loop stead simulation is executed using a data file. Secondly, the entry data file of clear weather is used as dynamic input and 14 days of closed loop control simulation is executed to the system on the circumstance of no interference. Then three entry wastewater data files in the data base of the wastewater treatment process are used and 14 days of respective control simulation is continued. Finally, the control result is evaluated using the closed loop control simulation result of the 21st day to the 28th day in the data base. The invention simulates the wastewater treatment process and establishes a corresponding data base. Various automatic control proposals are simulated and the proposal control effect is inspected according to an appointed evaluation standard, so a relatively excellent control proposal is obtained. The water quality is improved and the treatment energy consumption is reduced. The consumer simulation interface is friendly, which facilitates the research and development of the control proposal.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a wastewater treatment process control simulation method and a simulation system thereof. Background technique [0002] With the increasing shortage of water resources and the increasing emphasis on environmental pollution, wastewater treatment has attracted more and more attention. The wastewater treatment system requires that the treated wastewater meet the discharge standards stipulated by the state while minimizing the operating costs of the wastewater treatment plant, which is the fundamental goal of wastewater biological treatment. However, due to large fluctuations in water inflow, water quality components, and concentration, the treatment process is in an unstable state, resulting in fluctuations in effluent water quality and unstable system operation, making it difficult to achieve effective treatment goals. In order to ensure the optimal growth environment...
