Combined regulation and control method and system for urban drainage system

The invention discloses a combined regulation and control method and system for an urban drainage system, and relates to the technical field of rainwater and sewage regulation and control. Detection equipment is arranged at each node of an urban drainage pipe network, and water quality and water quantity data of the drainage pipe network are stored in a forest storage mode; the water quality and the water volume of the urban drainage pipe network are predicted by adopting an LSTM model; on the basis of constraint conditions of a sewage treatment plant model, an artificial wetland model and an urban river and lake model, an urban drainage system regulation and control model is further constructed, the model is solved through a particle swarm algorithm, and therefore under the condition that the water quality and quantity requirements of a sewage treatment plant, an artificial wetland and an urban river and lake are met, pollution is reduced, the urban water environment is protected, and the economic benefit is
