Embodiment Construction

[0062] Below in conjunction with specific embodiment to describe the present invention in detail:

[0063] Now take the activated sludge sewage treatment of a certain city as an example, and the amount of sewage discharged on a certain day is 15700m 3 , the sludge mass concentration of the mixed solution in the raw sewage is 2500mg / L, the BOD concentration of the influent is 200mg / L, and the volume of the reactor is 1500m 3 .

[0064] (1) Initial model and state setting

[0065] The model uses a 1.0×1.0×1.3 cuboid as the container, and a 1.0×1.0×1.0 cube as the sewage reaction space in the container, representing 1500m 3 . The sewage reaction space is divided into 10×10×10 nodes as the static nodes of the initial model, that is, the number of cells; 11×11×11 nodes are used as the diffusion nodes of the initial model. After the analysis of the activated sludge purification mechanism and the verification of some experiments, the present invention selects ΔT=1 / 3h, the initial...

Abstract

The invention discloses a cellular automata model-based visual simulation method for a sewage purification process, and belongs to the fields of intelligent science and environmental engineering discipline. In the method, a three-dimensional lattice gas cellular automata model is adopted, a cube represents a cellular structure of the cellular automata, and the central nodes of the cube represent a static node and a diffusion node of a cell respectively. By designing states of different nodes and an evolution rule comprising a diffusion process, a reaction process and a settlement process, the purification process of sewage treatment is simulated dynamically. Through the simulation model established by the method, the dynamic evolution behaviors of the sewage treatment process by a sludge method can be described more intuitively, so the micro evolution behaviors of an active sludge system are more clear and easy to grasp; and by intuitively observing reaction changes, the BOD of effluent quality can be timely monitored, the control decision is conveniently guided in real time, and the design and dynamic simulation of a sewage treatment plant are convenient.

Description

technical field [0001] The invention belongs to the subject field of intelligence science and environmental engineering, and in particular relates to a dynamic visualization model of a three-dimensional cellular automaton. The model shows the purification process of sewage treatment in real time. By visually observing the reaction changes of microorganisms and organic pollutants, the BOD of effluent water quality can be monitored in time, which is convenient for real-time guidance and control decision-making, and is convenient for the design and dynamic simulation of sewage treatment plants. Background technique [0002] With the growth of the national economy and the enhancement of public awareness of environmental protection, sewage treatment technology has ushered in unprecedented opportunities for development. The model is not conducive to the decision-making of control, and the control method is relatively backward. Therefore, establishing a more reliable, perfect and p...
