A management method for safe water supply from multiple water sources in cities

Abstract

A management method for safe water supply from multiple water sources in a city, the steps are as follows: 1) On the basis of collecting and organizing urban water supply data, establish a digital pipe network for the water supply system, conduct hazard analysis on the water supply pipe network of the water supply system, and propose control measures ; 2) According to the calculation model of water conservancy and water quality characteristics, determine the position of key points, formulate the key limits of key control points, clarify the control measures of key points, and establish the mathematical model of key nodes; 3) Use EPANET software to calculate the hydraulic characteristics of key points of water quality and establish multiple The water source city safety water supply management system provides basic data support for key point hazard control. The beneficial effects of the present invention are: the method can realize the digital management of the water supply system, clarify the problems existing in the pipe network, carry out necessary transformation on the pipe network, and achieve the best water supply management effect with the least human resources and energy consumption, ensuring The city's water supply security.

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, namely hazard analysis (Hazard Analysis) and critical control point CCP (Critical Control Point). [0003] At present, the scale of my country's ...

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
