Problems solved by technology
In the traditional method, the optimization of these parameters mainly adopts the process of building the reaction device-actual operation to obtain the treatment effect-feedback data-adjusting the structural parameters and then building the reaction device. In view of the long growth cycle of microorganisms, this process takes a long time and Adjusting the structure only according to the water treatment effect is not targeted, resulting in repeated operations and low efficiency

The invention provides an integrated ship domestic sewage membrane biological treatment device optimization method and system based on a CFD technology and a storage medium. The method comprises the following steps: establishing a physical model of an anaerobic / aerobic separation area in the sewage treatment device; defining a discrete region; performing mesh generation on the delimited discrete region; establishing a control equation, a turbulence model, a multiphase flow model and a porous medium model; setting boundary conditions; setting a discrete method; and carrying out numerical solution on a set discrete method, predicting the distribution characteristics of oxygen in the aerobic region and the anaerobic / aerobic transition region, judging the separation degree of the aerobic region and the anaerobic region, and optimizing the physical structure of the membrane biological treatment device. By analyzing the phase distribution cloud chart and the gas phase velocity vector diagramof the gas-liquid two phases in the anaerobic / aerobic transition area, the dispersion state of oxygen is predicted, the physical structure of the membrane biological treatment device is optimized ina targeted manner, the design and production efficiency of the sewage treatment device is improved, and the operation cost is reduced.
Description
technical field [0001] The present invention relates to the technical field of structural optimization of ship domestic sewage treatment devices, in particular to an optimization method, system and storage medium for an integrated ship domestic sewage membrane biological treatment device based on CFD technology. Background technique [0002] With the continuous development of the maritime transportation industry, the pollution problems faced by the ocean are becoming more and more serious. Therefore, countries around the world and the International Maritime Organization (IMO) have issued various regulations and standards for the domestic sewage discharged by ships during shipping, and the sewage Disposal emissions requirements are becoming increasingly stringent. The integrated ship domestic sewage membrane biological treatment device is a domestic sewage treatment device invented for the specific operating environment of the ship. This device uses the natural metabolic cap...
