Full-process intelligent control system based on AAO sewage treatment process

Abstract

The application provides a full-process intelligent control system based on an AAO sewage treatment process. The full-process intelligent control system comprises a data acquisition module, a water inlet pump group real-time control module, an aerobic tank aeration real-time control module, an internal backflow pump control module, a carbon source addition real-time control module, a phosphorous removal agent addition real-time control module, and a sludge discharge pump real-time control module. The real-time control modules provided by the application are suitable for sewage treatment plantswith a mainstream process based on the AAO process, and the key equipment in the process operation is intelligently controlled to effectively ensure that a sewage biological treatment system is in the best process operation conditions, so that different process units, with independent operation parameters, that seem to be independent on the surface, and operation conditions are integrated organically, and thereby the treated outlet water is ensured to meet the standard, the energy consumption of the key equipment and a use amount of a carbon source and a phosphorus removal agent and other medicaments can be reduced, and the goal of maximizing energy-saving and consumption-reduction in sewage treatment plants is ultimately realized.

Description

technical field [0001] The application belongs to the field of environmental engineering sewage treatment, and in particular relates to a full-process intelligent control system based on AAO sewage treatment process. Background technique [0002] AAO (Anaerobic-Anoxic-Oxic, Anaerobic-Anoxic-Aerobic) sewage biological treatment process is currently a widely used sewage treatment process. In this process, sewage flows through anaerobic zone, anoxic zone and aerobic zone in sequence. Therefore, the biological treatment process of AAO sewage has high COD (chemical oxygen demand) removal and nitrogen and phosphorus removal effects. Specifically, in the AAO process, the raw wastewater first enters the anaerobic zone, and the facultative anaerobic fermentation bacteria convert the biodegradable macromolecular organic matter in the raw wastewater into volatile fatty acids (VFA) and other smaller molecular weight organic compounds in the anaerobic environment. The intermediate ferme...

Problems solved by technology

[0007] In order to solve the problems that each process section of the traditional sewage treatment process based on the AAO process can only achieve individual and local control, and it is difficult to integrate with the overall operation system of the treatment process, resulting in large drug consumption and energy consumption, this application provides a sewage treatment plant The mainstream process section and equipment-based intelligent control system for the key operating equipment of the sewage treatment plant, so that the local precise control unit can be organically integrated with the overall sewage treatment system to achieve more effective energy saving and consumption reduction
