Abstract

The invention discloses a method for constructing a biomembrane model of membrane biological sewage treatment. The method comprises the steps that a lattice Boltzmann equation is selected according tophysical models of a biomembrane and a reacting device; a deformable boundary treatment format of the biomembrane is determined according to the selected lattice Boltzmann equation, and macro parameters of the biomembrane under different flow rate conditions are obtained, wherein the macro parameters at least comprise the position of biomembrane boundary, fluid density, deformation speed and thestressing parameter of the biomembrane boundary over time; aspect graphs of the biomembrane under different flow rate conditions are drawn according to the obtained parameters, and the interaction between the biomembrane and the fluid under different flow rate conditions is simulated and calculated to determine the moving situation of a biomembrane interface. According to the method, by the simulation of an internal flow field of a membrane biological reacting device and values of biomembrane boundary deformation, the moving characteristics of the biomembrane and the influence of deformation of the biomembrane in solvent fluid on flowing characteristics are studied to further provide a certain degree of guiding and predicting for actual engineering application.

Description

technical field [0001] The invention relates to the field of membrane biological sewage treatment, in particular to a biofilm model construction method for membrane biological sewage treatment. Background technique [0002] In modern society, a large number of industrial enterprises, such as textiles, paper, pulp, printing, steel, coke, petroleum, pesticides, paints, solvents, pharmaceuticals, etc., produce a large amount of industrial wastewater, which contains various organic substances that are harmful to humans and the environment. Chemical material. Therefore, these industrial wastewaters need to be degraded or detoxified by physical, chemical or biological treatment techniques before being discharged into the environment. Membrane biological sewage treatment is a new type of sewage treatment method, which provides self-growth through microbial degradation of organic matter in sewage. Among them, photosynthetic bacteria can also generate clean energy hydrogen while de...
