Embodiment Construction

[0066] Now take the domestic sewage treatment in a certain city as an example, and the sewage discharge volume in a certain day is 20000m 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 1900m 3 .

[0067] The realization of this embodiment comprises three steps:

[0068] 1. The present invention is based on the HPP lattice gas cellular automaton rule, firstly to establish the corresponding initial model in the activated sludge system, and initialize the cellular state.

[0069] Taking the 1×1 coordinate as the two-dimensional space, divide the coordinate into 101×101 nodes as the initial model.

[0070] The state of the cell: the state of the r cell and the t time step is expressed as s(r, t)=(xxxxx), the state of the central node is determined by the first digit on the left, and this node can only be occupied by microbial particles. The presence of micr...

Abstract

The invention discloses an analogy method based on an activated sludge purification process of a HPP lattice gas cellular automaton model, comprising the following steps: setting up a corresponding initial model in an activated sludge system and initializing a cellular state; setting a boundary point; and ensuring an evolution rule according to the initial model. The method comprises the reactionprocess of particles; and the reaction process comprises particle absorption, particle catabolism, particle anabolism and endogenous respiration. Based on an artificial life system and the HPP lattice gas cellular automaton model, the invention designs the evolution rule of an activated sludge cell automaton and realizes the evolution, simulates a circumstance that microorganism absorbs and decomposes organic matters, well simulates the logarithmic phase, the decelerating grow phase and the endogenous respiration phase of an activated sludge growth model curve, well simulates the degradation curve of BOD organic matters, and has a directive function for further recognizing and understanding the saprobia settlement process.

Description

technical field [0001] The present invention relates to a kind of simulation method of activated sludge purification process, in particular to a kind of activated sludge based on the lattice gas cell automata proposed by HPP (Hardy, de Pazzis and Pomea, referred to as HPP) lattice gas cell automata model The simulation method of the purification process, which is of great value for the analysis of the sewage treatment process and the design of the controller, belongs to the field of intelligent science and environmental engineering. Background technique [0002] The essence of the process of purifying wastewater by activated sludge method is the process in which organic matter is taken up, metabolized and utilized by activated sludge microorganisms as nutrients, that is, the process of "activated sludge reaction". As a result of this process, the waste water is purified and the microorganisms gain energy to synthesize new cells, allowing the activated sludge to grow. Durin...
