A full-process intelligent control system based on aao sewage treatment process

Abstract

This application provides a full-process intelligent control system based on AAO sewage treatment process. The full-process intelligent control system includes a data acquisition module, a real-time control module for water inlet pump formation, a real-time control module for aeration in an aerobic tank, and a control module for an internal reflux pump. , carbon source dosing real-time control module, dephosphorization agent dosing real-time control module and sludge pump real-time control module, the real-time control module provided by this application is suitable for the sewage treatment plant of mainstream technology based on AAO technology, through intelligent control The key equipment in the process operation is to efficiently ensure that the sewage biological treatment system is in the best process operating conditions, so that the seemingly irrelevant, independent operating parameters of different process units and operating conditions are organically integrated, thereby ensuring that the treated water reaches the standard , and can reduce the energy consumption of key equipment and the use of chemicals such as carbon sources and phosphorus removal agents, and finally achieve the goal of maximizing energy saving and consumption reduction in sewage treatment plants.

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
