Abstract

The invention belongs to the environmental protection technical field and control field and specifically relates to a sewage treatment process energy-saving optimization control method based on a quantum genetic algorithm. The method is characterized in that, with effluent quality, aeration, pumping energy consumption and sludge and waste treatment cost being taken into overall consideration, quantum state vector expression is introduced to genetic encoding to express chromosomes, and evolutionary search is achieved by utilizing quantum gate effect and update so as to optimize operating cost of sludge and waste treatment, backflow and aeration energy consumption and the like of a sewage treatment system; and aeration intensity of an air blower and sludge pump backflow amount are adjusted by a fuzzy neural network controller in real time based on a set value after optimization so as to realize optimization control of the sewage treatment process, thereby reducing the operating cost while ensuring the effluent quality, reducing the sewage treatment cost and promoting efficient and stable operation of a sewage treatment factory.

Description

technical field [0001] The invention relates to the field of environmental protection control, and more specifically, to an energy-saving optimization control method for sewage treatment process based on quantum genetic algorithm. It comprehensively considers the effluent water quality, aeration and pumping energy consumption and sludge waste treatment cost, and dynamically optimizes the operating costs of sludge waste treatment, backflow and aeration energy consumption of the sewage treatment system, and is adjusted in real time by the fuzzy neural network controller Blower aeration rate and sludge pump return rate to achieve optimal control of the sewage treatment process. Background technique [0002] With the rapid development of economy and society, water pollution is becoming more and more serious, which has threatened the survival of all living things. Research and promotion of efficient, stable and economical new sewage treatment technologies have attracted great att...
