Problems solved by technology

However, at present, the operation and management level of my country's urban drainage system is relatively low, the aging of drainage pipe network facilities and the complexity of the connection relationship of the drainage pipe network have led to increasingly prominent problems such as the collapse of the drainage pipe network, sewage overflow, and urban waterlogging.

Embodiment Construction

[0157] The following embodiments describe the present invention in more detail, but they do not limit the scope of the present invention. Specifically, some specific implementations of the present invention will be described below by taking the screening and evaluation of the pumping station dispatching scheme as an example.

[0158] The operation of a certain pumping station in a certain area is uniformly dispatched by a certain regional pipe network to control the start and stop of the pump. The pumping station has a designed flow rate of 35,000 tons per day, and is equipped with 4 submersible sewage pumps (3 of which are used as a backup) of the model 350WQ1100-10-45. Only 1 of the pumps in the pumping station is turned on and turned on regularly during the morning and evening drainage peaks. The time is shorter, thereby creating a risk of pipe overload and overflow. Therefore, under the condition of ensuring the safe and stable operation of the pipeline network, the sched...

Abstract

The invention provides a method for optimizing the running state of an urban drainage system. The method comprises the following steps: (a) running parameter values of a plurality of running schemes of the urban drainage system are used for calculating values of a plurality of third-class indicators of each running scheme; (b) one or more third-class indicators is selected, normalized processing values of the chosen third-class indicators are respectively calculated, and summation is carried out on the normalized processing values of the chosen third-class indicators and the weighted products to obtain corresponding second-class indicator values; and (c) one or more second-class indicators is selected, summation is carried out on the chosen second-class indicator values and the weighted products to obtain corresponding first-class indicator values, and a running scheme is selected according to the first-class indicator values for optimizing the running state of the urban drainage system. The method provided by the invention can be used for helping to carry out drainage system running decision making, such as current situation assessment?of the drainage system, selection of control schemes, comparison?and?selection of drainage planning schemes and optimal selection of running maintenance schemes.

Description

technical field [0001] The invention relates to a method for optimizing the operation status of the urban drainage system, especially a method for evaluating the operation status of the urban drainage system by using a multi-level evaluation index system, and a method for optimizing the operation status of the urban drainage system by using the evaluation results. Background technique [0002] Urban drainage system is an important part of urban infrastructure. It not only undertakes the tasks of urban flood control, drainage and collection of sewage from urban life and industrial production, but also relates to urban landscape, environmental sanitation and water environment safety. With the continuous development of my country's economy and society and the continuous advancement of urbanization, people's requirements for living environment are gradually increasing. However, at present, the operation and management level of my country's urban drainage system is relatively low...
