Method for managing safe water supply of multiple water resources in city

Abstract

Provided is a method for managing the safe water supply of multiple water resources in the city. The method comprises the following steps that (1), on the basis of collecting and systemizing city water supply materials, a water supply system digital network is built, hazard analysis is carried out on a water supply network of a water supply system and control measures are provided; (2), according to a water conservancy and water quality characteristic calculation model, the position of critical points is determined, the critical limit value of the critical control points is made, the control measures of the critical points are cleared, and a critical node mathematical model is built; (3), EPANET software is adopted to calculate the water conservancy and water quality characteristics of the critical points, a multi-water-source city safe water supply management system is built, and basic data support is provided for hazard control of the critical points. The method has the advantages of being capable of achieving digital management on the water supply system, clearing out the problems existing in the network, carrying out necessary modification on the network, achieving the best water supply management effect through the minimum consumption of manpower resources and energy, and ensuring water supply safety of the city.

Description

technical field [0001] The invention relates to urban water supply management technology, in particular to a management method for safe water supply from multiple water sources in cities. Background technique [0002] HACCP is the abbreviation of "Hazard Analysis Critical Control Point" in English, which means Hazard Analysis and Critical Control Point. It is a preventive management system based on the safety of consumers in the food processing process. It is different from the traditional quality inspection method. The HACCP management system focuses on the potential hazards in the entire production process, rather than relying mainly on the final quality inspection. It aims to effectively prevent and control hazards during the production process. control. It can be clearly seen from the name of HACCP that it mainly includes HA (Hazard Analysis) and CCP (Critical Control Point). [0003] At present, the scale of my country's urban water supply network continues to expand ...

AI Technical Summary

Problems solved by technology

[0003] At present, the scale of my country's urban water supply network continues to expand and its distribution is becoming more and more complex. However, the management methods of water supply are relatively backward. There is no unified dispatching management for water supply from multiple sources. Some water supply units still adopt traditional manual management methods and paper management methods. The storage method of network data can only be checked through manual file adjustment when necessary, which has a large workload and low work efficiency

In addition, with the continuous development of the economy, the old multi-source urban water supply management system can no longer guarantee the demand for safe water supply. Water supply quality management means and improvement of pipe network management have become an important way to ensure water supply safety
