Based on the research of large and medium-sized cities in China, this research develops an intelligent pressure regulation system aimed at leakage control and water quality assurance to reduce the total amount of water leakage in urban pipelines, improve the quality of urban drinking water and ensure water supply security. For rural residents scattered, poor water quality, low maintenance of technical conditions, research and development for the village and town with low input, low cost, high efficiency and energy saving, intelligent water and transport water supply system. In view of the above tasks, the research unit has broken through the verification technology of network nodes’ traffic flow and proposed a matrix node flow calibration method based on generalized inverse theory. The real-time large-scale network hydraulic model system was developed and applied in Guangzhou , Providing technical support for the pressure regulation of large-scale water supply system. Independent research and development of pipe network pressure intelligent control equipment, according to the entrance pipe network pressure, user demand for water, as well as the pipe network pressure on the premise of ensuring the urban water demand on the premise of pipe network pressure control automatically reduce water pressure, Reduce leakage good, has been put into practical application testing. In view of the existence of a large number of pollutants in the external environment of the water distribution network, low negative pressure is caused by the intrusion of sewage outside the pipe. The research group carried out the experimental study of the leakage model and designed the leakage of the pipe network under the condition of low negative pressure Of the invasion volume measuring device, and applied in the experimental platform to obtain the value of the invasion volume caused by the low negative pressure event, analyzed and summarized the various factors affecting the size of the pipe network invasion, and achieved phased results; for rural water consumption Variable coefficient of large-specific, developed a gas-controlled intelligent inverter tower centralized automatic water supply equipment, including the design of closed tank, water pump and water pipes, pumps, intelligent control module integration equipment. Visual remote adjustment, monitoring and maintenance. Achieve unattended, reducing operation and maintenance costs 20% to 35%. In view of the low groundwater iron and manganese in rural areas in Huarong, the economic and technological level of villages and towns is low. R & D for water purification equipment that is suitable for villages and towns and integrates flocculation, sedimentation, filtration, iron and manganese removal and disinfection has been put into demonstration projects.
