Analogue simulation system of mixing clarifying tank and calculation method thereof

The invention relates to an analogue simulation system of a mixing and clarifying tank and a calculation method of the analogue simulation system, and the analogue simulation system comprises an initial external variable input module, an intermediate process external variable input module, a mixing chamber simulation calculation module, a clarifying chamber simulation calculation module and an iteration control module. The change of external flow parameters in the analogue simulation process is set, the running state of the mixing chamber and the running state of the clarifying chamber are simulated and calculated according to the set initial flow parameters and related data of external variables in the middle process, and the minimum time unit and the number of iterations in the iterative calculation process are controlled to conduct iterative calculation. By adopting the method disclosed by the invention, various theoretical models of pressure balance, weir flow model, extraction balance, heterogeneous mixi
