Water is the foundation of human existence and the source of civilization.

Hubei, a province of thousands of lakes, has always been excellent because of water, and worried about water. Coordinating and promoting the comprehensive management of river basins, how to be more green and efficient? At the 2023 (Fifth) China Urban Water Environment and Water Ecological Development Conference, more than 20 Chinese and foreign academicians and experts "checked the pulse" and proposed scientific and technological empowerment to ensure effective water safety, efficient use of water resources, and obvious water ecology. Improved intensive and economical development path.

Foreign academicians praise Hubei

71-year-old Glen Thomas Daigger (Glen Daigger) is an academician of the American Academy of Engineering and a foreign academician of the Chinese Academy of Engineering. At the meeting, he specifically mentioned the multiple advantages of MABR technology in sewage treatment, especially in the Xiaogan area of Hubei Province, which is worthy of recognition.

MABR is a new sewage treatment technology that combines gas separation membrane technology and biofilm treatment technology. In the Xiaogan service area of the Beijing-Hong Kong-Macao Expressway, the sewage generated by auto repair shops and restaurants flows through several "containers" in the backyard after treatment and becomes a gurgling water flow, forming a small ecological wetland planted with flowers and plants. This is a decentralized sewage treatment system built by Xiecheng Environmental Protection Company, a subsidiary of Hubei Jiaotou Intelligent Testing Company. It integrates the world's leading MABR membrane components. Through the intelligent environmental protection monitoring and management platform, real-time remote monitoring of sewage treatment is realized, and one-key intelligent treatment of sewage is realized. The life span is 15 years. At present, the system has been put into use in 162 sets of equipment in 141 stations including expressway service areas, parking areas, and toll stations, achieving the standard treatment and reuse of about 15,000 tons of sewage every day.

"Water steward" changes the shape of the Yangtze River

The water plants at the bottom of the lake are swaying, and the water birds are flocking on the surface of the lake. Stroll along the bank of Tangxun Lake, the largest lake in the city in Asia, with green grass on the bank and ducks swimming in the water.

The Yangtze River Environmental Protection Group, a subsidiary of the Three Gorges Corporation, invested nearly 5 billion yuan in the second phase of the Tangxun Lake Water Environment Comprehensive Treatment Project, which is expected to start this year.

Water pollution control "black and odorous in the water, rooted in the shore, the core is the pipe network." For this reason, Wang Dianchang, chairman of Changjiang Environmental Protection Group, proposed the "urban smart water steward" model. "Water steward" is the main body that manages all water-related affairs in the city. From raw water to water supply, from sewage to flood control and drainage, the "water steward" manages everything above and below ground, on the river and on the bank.

He believes that the "urban smart water steward" can raise the "floor" for the high-quality development of the Yangtze River Great Protection. It bids farewell to the previous "Kowloon water control" model, takes the initiative to undertake the pressure of urban water environment assessment, and at the same time solves the "pepper-spreading" point-shaped governance model, and invests accurately and saves investment. In addition, the battle for the pipeline network of "focusing on the management of the pipeline network to promote the transformation of the water environment from temporary to permanent solutions" has been launched. In addition, an investment platform for the Yangtze River pipeline network will be established to innovate the "pay-for-performance" mechanism, reduce the cost of pipeline network construction and operation, and explore new ways of sustainable development.

Put the "core" of wisdom on the Yangtze River

A piece of cutting-edge technology has brought the Yangtze River back to life and vitality. The "quantum dot spectral sediment detection equipment" displayed at the conference can detect the river sediment content in 10 minutes, and has been applied to the Wuhan section of the Yangtze River. According to the staff of Core Vision Technology Co., Ltd., in the past, water quality testing required at least 3 to 5 people to work together for 7 days from sampling to results.

"Achieving comprehensive management of the Yangtze River Basin requires scientific and technological innovation." Xia Jun, academician of the Chinese Academy of Sciences, water resources expert, and professor of Wuhan University, said.

In 2019, the Chinese Academy of Sciences launched the Yangtze River Simulator Project. This is a comprehensive simulation and regulation decision-making system for the Yangtze River Basin driven by big data, which coordinates the natural ecology and socio-economic ecological governance of the Yangtze River Basin. To put it simply, the Yangtze River Simulator is like a large project that incorporates the entire Yangtze River Basin into an "intelligent system". The completed form of the simulator can provide testing, water circulation in the basin, lakes and reservoirs, shorelines, urban agglomerations, and water ecology. Large plate integration and control decision-making and evaluation. Last year, the Yangtze River had a rare "flood season anti-drying". The project team used the Yangtze River simulator platform and flood and drought disaster models to issue early warning predictions. Xia Jun revealed that their team is advancing the forecast of flood and drought trends in the main flood season of the Yangtze River in 2023.
