Function optimization method for city water-supply pipe network

Abstract

The invention discloses a function optimization method for a city water-supply pipe network, which is characterized by comprising the following steps of: establishing an operation information system database of a town water-supply pipe network according to the current situation information of a city water-supply pipe network for hydraulic computation; calculating the cost index, the function index and the value index of the water-supply pipe network with the function of the water-supply pipe network as a unit; and carrying out evaluation on the integral performance and the assemblies of the water-supply pipe network with the value index as a reference, and obtaining a function optimization scheme of the pipe network according to an evaluation result to further realize energy-saving operation and water-saving operation of the pipe network. The invention provides an optimization method for saving energy and reducing consumption for city water resources, supplying water with low carbon, enhancing the utilization ratio of the city water resources and promoting the sustainable development for the city water resources and has higher practical value.

Description

technical field [0001] The invention relates to a method for design and operation function optimization of an urban water supply system, belonging to the field of urban water resource energy saving, emission reduction and sustainable development. Background technique [0002] With the increase of population, improvement of living standards and rapid economic development, the demand for water in society is increasing year by year, and the water supply network is becoming larger and more complex. How to achieve energy saving and emission reduction in the water supply network system, and then promote the sustainable development of urban water resources is a problem that needs to be solved urgently. Currently. The design and evaluation methods of the water supply network mainly adopt hydraulic evaluation, water quality evaluation and reliability evaluation, and evaluate the design and operation status of the water supply network from the perspective of hydraulics and water qual...

Problems solved by technology

[0004] However, in the application of value engineering methods at present, most researchers mainly focus on the design and development of individual products, such as the research and development of water pumps, the selection of pipe materials, etc., without considering the design and operation of the overall water supply network system. Therefore, there is a lack of holistic and comprehensive design evaluation, and the function optimization, energy saving and sustainable development of the water supply network cannot be fully realized.
