Abstract

The invention belongs to the technical field of municipal sewage and discloses a precise aeration control system for sewage treatment fuzzification, which comprises a front end instrument, a frequencyconversion system and a back end control system. The back end control system comprises a PLC control system, a touch screen and a fuzzy controller; a programmable logic controller of the PLC controlsystem is in communication with the fuzzy controller and the touch screen, respectively; a fuzzy control method based on a precise aeration control system fuzzy controller is provided. The precise aeration control system and the fuzzy control method for sewage treatment fuzzification in the invention solve the problems that the traditional control system can interfere with the work of a biologicalsystem due to high energy consumption and too large fluctuation, a failure of the whole control system is caused after some instrument in the system breaks down, and inaccurate system measurement parameters cause wrong control output.

Description

technical field [0001] The invention belongs to the technical field of municipal sewage, and in particular relates to a precise aeration control system and a fuzzy control method for fuzzy sewage treatment. Background technique [0002] For a sewage treatment plant of a certain scale, its energy utilization varies significantly depending on its location, sewage concentration, treatment depth, reuse in the plant, process selection and operation mode, so it is not practical to propose a universally applicable energy consumption level for sewage treatment plants Yes, usually traditional biological lagoons and land treatment systems are insensitive to changes in energy consumption. Advanced treatment processes often require large amounts of primary energy, as well as chemicals and related secondary energy. Factors such as influent concentration, water conservancy conditions, design and operation mode of energy recovery in the plant have a great influence on the consumption of e...
