Side notes of the Rural Water Supply Modernization Development Technology Seminar. Experts elaborate on their perspectives from multiple perspectives

Recently, a seminar on rural water supply modernization development technology was successfully held in Chengdu, Sichuan. During the keynote report session, a number of high-level experts shared their academic views on urban and rural water supply security, rural water supply modernization paths, national water network project construction, regular support policies for rural revitalization, and how artificial intelligence can empower rural water supply security. The branch venue set up three special topics: "Rural Water Supply Construction", "Rural Water Supply Water Quality Guarantee" and "Rural County Unified Management and Smart Water Supply". A total of 30 special reports were carried out with diverse perspectives and highlights. Each report condensed technological innovation and practical exploration, providing solid technical support for the modernization of rural water supply.

Drinking water safety and health

Ma Jun, professor at Harbin Institute of TechnologyIt is proposed that water is not only the source of life, but also bears the dual functions of nutrient transportation and metabolic excretion. At present, urban and rural water sources are facing multiple challenges such as eutrophication, heavy metals, and chlorine-resistant microorganisms. Traditional water supply processes are difficult to meet the requirements of the new national standards. It is recommended to implement new technologies such as green multi-functional water purifiers, advanced oxidation, and inorganic membrane filtration. At the same time, control non-point source pollution from the source, achieve the low-carbon water purification goal of "removing harmful substances and retaining beneficial minerals", and provide highly adaptable and easy-to-maintain integrated equipment for rural water supply.

Rural water supply modernization

Chen Mingzhong, executive vice president of China Agricultural Water Saving and Rural Water Supply Technology AssociationIntroduction: At present, rural residents in some remote areas of our country still rely on water cellar water tanks for water supply. Some mountainous areas have seasonal water shortages and insufficient water quality assurance and management and protection capabilities. It is necessary to continue to promote the implementation of the "3+1" standardized construction and management and maintenance model of rural water supply, promote the "three transformations" of rural water supply, and optimize the layout of projects through "large construction, merging, and downsizing" to reasonably reduce the population of scattered water supply; improve the full-process water quality assurance system from water source to faucet in accordance with the new national standards; focus on standardized construction, standardized management, unified county management, digital empowerment and emergency support, so that rural residents can realize the transformation from "drinking water" to "drinking good water".

Construction of backbone water network

Wang Hua, Chairman of Sichuan Water Conservancy Development Group Co., Ltd.It looks forward to the seven major empowerments of the Dadu-Min River Diversion Project for urban and rural water supply: first, water conservation is given priority, forcing efficient use of water resources; second, multi-source interconnection, using the "Dado River + Min River" dual water source pattern to enhance regional water security resilience; third, plant network optimization, laying out large-scale water plants along water transmission trunk lines to promote plant-network linkage; fourth, water rights restructuring, external water diversion gives priority to ensuring domestic and industrial water use, replacing Local water returns to ecology and agriculture; the fifth is the water price mechanism, establishing a two-part water price of "basic water price + metered water price" to ensure the sustainable operation of the project; the sixth is institutional and mechanism innovation, promoting the market-oriented operation model, and realizing "same source, same network, same quality, same supervision, and same service"; seventh is full-chain water quality monitoring, implementing closed control and automatic monitoring of water intakes and water transmission trunk lines.

Rural revitalization

Liu Xiaoshan, former deputy director of the Development Guidance Department of the National Rural Revitalization AdministrationAccording to the introduction, during the "15th Five-Year Plan" period, the strategic status of rural revitalization has undergone profound changes. It will achieve a historic transition from "basic support" to "overall improvement" and build a goal system in three dimensions: "industry, security, and people's livelihood"; in the development dimension: build agriculture into a modern large industry; in the security dimension: maintain the "two lifelines" of national food security and prevent large-scale return to poverty; in the people's livelihood dimension: let rural areas basically have modern living conditions. Innovate the practical path to drive agricultural modernization with new productivity and systemic reforms, build a new pattern of regular targeted assistance and high-efficiency rural governance, build a livable, industrial and beautiful countryside while promoting common prosperity, and let the vision of "strong agriculture, beautiful rural areas, and prosperous farmers" take root.

artificial intelligence

In terms of artificial intelligence, AI is reshaping the water conservancy industry at an unprecedented speed.Liu Xuemei, former vice president of North China University of Water Resources and HydropowerIt is believed that by building a "digital expert" system that collaborates with multi-modal large models and agents, water conservancy data islands, knowledge barriers and decision-making pressure can be solved. She took the multi-modal large model of engineering safety as an example, combined with related typical application scenarios, to vividly demonstrate the entire intelligent decision-making chain from risk identification and assessment to automatic generation of emergency plans. She emphasized that "the large model is the brain, and the agent is the hands and feet." In the future, enterprise IT systems will take large models as the core, promoting AI to transform from a tool attribute to a productivity attribute.
