Sewage treatment process optimization and energy-saving control system and method

Abstract

The invention provides a sewage treatment process optimization and energy-saving control system and a sewage treatment process optimization and energy-saving control method. The sewage treatment process optimization and energy-saving control system comprises a computer, an upper computer, an executing mechanism, more than one on-line monitoring instrument and more than one piece of water quality adjusting equipment, wherein the more than one on-line monitoring instrument is used for acquiring a water quality parameter of treated sewage; and the more than one piece of water quality adjusting equipment is used for adjusting the water quality parameter of the sewage. By acquiring sewage treatment field data, performing simulation treatment on the field data through a simulation model and calculating through a control model, a control signal is obtained to control the operation state of the water quality adjusting equipment so as to form a feed forward-feedback-control model calculation-execution artificial intelligent closed-loop control loop; and the water quality parameter which meets the process requirements can be calculated, and accurate control is performed on the parameter of the sewage water quality process, so that a sewage treatment process optimization and energy-saving effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment process optimization and energy-saving control system and method. Background technique [0002] In recent years, with the rapid development of industry, the problem of sewage pollution has become increasingly serious. At present, in the sewage treatment process, the biological treatment process is a widely used sewage treatment technology, and its process is a complex biochemical process. In the sewage treatment process, in order to ensure the efficiency of sewage treatment, it is necessary to strictly control multiple water quality parameters in the sewage treatment process. For example, when the sewage is treated by the pretreatment equipment and flows into the oxidation ditch, anaerobic-aerobic During the reaction, in order to ensure the treatment efficiency of the sewage in the oxidation ditch, it is necessary to ensure that the dissol...

Problems solved by technology

However, due to the variability of sewage water quality and the complexity of biochemical reactions in the biological treatment system, the adjustment time of the aerator speed often lags far behind the time when the test results are obtained, resulting in the sewage water quality discharged from the oxidation ditch not meeting the requirements, reducing the Sewage treatment efficiency
