Method of controlling sequencing batch activated sludge process (SBR) intelligently based on fully coupling activated sludge models (FCASMs) and embedded system

Abstract

The invention discloses a method of controlling a sequencing batch activated sludge process (SBR) intelligently based on fully coupling activated sludge models (FCASMs) and an embedded system. The method comprises the steps of establishing an SBR numerical simulation model through matrix laboratory (MATLAB) software, carrying out numerical simulation calculation with the SBR numerical simulation model under the environment of the LabVIEW, and obtaining a timing sequence parameter, a process parameter and given values of environmental conditions; and collecting the environmental conditions in an SBR reactor in real time under the environment of the LabVIEW based on the PCI extensions for instrumentation (PXI) platform, and carrying out real-time negative feedback control on the SBR according to the given values of the environmental conditions. By combining the numerical simulation model and the embedded system based on the PXI platform, real-time and optimizing control of the SBR is achieved, the sewage treatment effect is improved, and therefore the method has potential economic benefits.

Description

technical field [0001] The invention relates to the technical field of sewage treatment simulation and control, in particular to a method for intelligently controlling an SBR process based on an FCASMs mechanism model and an embedded system. Background technique [0002] With the development of automation and control technology, the SBR sewage treatment process began to emerge rapidly in the field of sewage treatment all over the world in the 1970s and 1980s. The SBR method is the abbreviation of the sequential batch activated sludge method. It is an activated sludge sewage treatment technology that operates according to the intermittent aeration method, also known as the sequence batch activated sludge method. , aerobic stage, sedimentation, decanting stage, idle stage and sludge discharge stage. SBR sewage treatment technology adopts the operation method of time division instead of space division, the unsteady biochemical reaction replaces the steady state biochemical rea...

Problems solved by technology

However, various models (ASMs, etc.) launched by IWA (International Water Association) and European countries are based on the water quality conditions and biological components in which domestic wastewater accounts for more than 95% of domestic wastewater, and are not suitable for industrial wastewater in my country. More than 30% of the sewage water quality, so it is necessary to develop a model suitable for the current situation of sewage treatment in my country

However, most scholars in my country are engaged in the research of pure intelligent control such as fuzzy control and expert system, and often cannot achieve precise control of the operating process of the activated sludge system.
