The invention relates to the technical field of sewage purification treatment, in particular to a sewage treatment method and system based on fusion of an activated sludge model and CFX, and the method comprises the following steps: S1, implanting original parameters and original sub-models in ASM into CFX to obtain a CFX calculation model for sewage treatment; S2, dividing the three-dimensional model of the sewage biochemical pool into grids, importing the grids into a CFX calculation model for calculation, and calculating the influence of different parameter factors on the treatment effect. The ASM is completely embedded into the CFX, so that detailed and comprehensive operation of sewage treatment is realized, and the method has very strong guiding significance on sewage treatment design, including arrangement of parts in a biochemical pool, accurate aeration control, accurate carbon source addition, mixed liquid and sludge reflux control and the like; the method has practical significance for solving the problems of high cost, high energy consumption and the like in the operation of an existing urban sewage treatment plant, and also has important guiding significance for the operation of an old sewage plant and the optimization design of a newly built sewage treatment plant.
Description
technical field [0001] The invention relates to the technical field of sewage purification treatment, in particular to a sewage treatment method and system based on the fusion of activated sludge model and CFX. Background technique [0002] Most of the current sewage treatment simulation methods such as fluid mechanics simulation CFX are limited to one-dimensional and two-dimensional calculations, which can only calculate the parameters of water inflow and outflow of structures, but cannot calculate the internal conditions of biochemical tanks, and cannot clearly represent the progress of biochemical reactions; a few three-dimensional simulations The software can only simply couple a few parameters, and cannot perform a complete calculation of the system for sewage biochemical treatment; the sewage treatment plant is only designed based on experience, and a considerable part of the process has high energy consumption problems, such as: excessive aeration, a On the one hand, ...
