[China Intelligent Manufacturing Network Industry Trends] On March 12, 2019, UN-Habitat and Tongji University in China jointly released "Strengthening River Pollution Control and Achieving Sustainable Urban Development: China and Other Developing Countries" Experience” report. The report introduced the case of environmental improvement of the Suzhou River in Shanghai, China. Maimouna Mohd Sharif, Executive Director of the United Nations Human Settlements Program, also said that China’s successful experience in treating polluted rivers has provided an example for other developing countries and focused on Come to the "river chief system".
Praised by the United Nations Human Settlements Agency for how strong China's river management is
< div> Xu Zuxin, a professor at Tongji University, said that the success of Suzhou River management stems from various factors such as the attention of all parties, joint deployment, collaborative practice, scientific decision-making, and innovative technology. As we all know, the Shanghai section of the Suzhou River spans 12 districts and has more than 2,000 small and medium-sized rivers. It was once a typical black and smelly river. It would take 20 days for a rafting bottle to go from Beixinjing to the mouth of the river. The water power is seriously insufficient.
Suzhou River
However, Shanghai has successfully awakened this mother river through decades of continuous management. At present, all black and odorous rivers have been eliminated in the main streams, and the water ecology is also being restored. How?
Dating back to 1988, Shanghai began to renovate the Suzhou River. The comprehensive environmental management project of the Suzhou River was successfully launched. Now in 2019, the fourth phase of the Suzhou River management has been launched, a huge project. Eye-catching. In 1996, Shanghai established the Suzhou River Environmental Comprehensive Improvement Leading Group, which also recognized the need for overall advancement and comprehensive management.
Looking at the first three phases of the Suzhou River treatment project, from the elimination of black odor in the main stream of the Suzhou River, designated pollution interception and pollution control and ecological restoration to the dredging of the bottom mud of the Suzhou River, the goal is to stabilize the water quality of the main stream. Clearly, the task was successfully completed. Measures such as the renovation of the Wusong Road gate bridge, the construction of tributary gates and pollution control projects, and the synchronization of supporting projects on both sides of the river have been implemented one after another, making citizens look forward to the beautiful scenery of the Suzhou River after the completion of the fourth phase of treatment.
Of course, this is not the only epitome of river pollution control in my country. I believe that many people still remember the transformation of the Yongding River.
Yongding River
“ Yongding River, out of the Xishan Mountains, surrounded by clear water around Beijing Bay. "It is not difficult to feel that the residents are now quite satisfied with the results of the Yongding River management. In 2004, the Heituwa constructed wetland project near the entrance of the Yongding River in the Guanting Reservoir was put into operation; since 2009, Beijing has used a circulation pipeline to bring 5 Gehu.
In 2015, the "Beijing-Tianjin-Hebei Coordinated Development Plan" listed six rivers, including the Yongding River, as the focus of comprehensive management and ecological restoration; at the end of 2016, the country The three ministries and commissions jointly issued the "Overall Plan for Comprehensive Management and Ecological Restoration of the Yongding River"; in 2017, the Sanggan River in Shanxi Province, one of the sources of the Yongding River, launched the "Clean River Action". By the end of 2018, more than 3,400 cubic meters of garbage and debris had been cleared from the Yongding River Basin in the Beijing section. By the end of 2019, the Beijing section of the river is expected to be connected. By 2020, the Yongding River comprehensive management and ecological restoration project system is expected to be basically completed. By 2025, it will become an important water source. The water quality reaches Category III to IV.
Tongshun River
Let’s look at another river that starts from the Han River and flows into the Yangtze River. The Tongshun River, which is more than 190 kilometers long, has also suffered from the deterioration of water quality from Class II to Class V. In recent years, the effectiveness of Hubei's implementation of the river chief system in Tongshun River has been highlighted. div> The management of the Tongshun River implements a five-level river chief system, with unified and comprehensive dispatching of 16 culvert gates and 4 pumping stations. By formulating refined solutions and exploring a joint dispatching model of water resources and water ecology, the Tongshun River has been recuperated and recuperated. time. At the same time, the water quality of the river was included in the 24-hour monitoring, and many enterprises and farms with substandard sewage discharge were shut down along the way.
It is understood that at the end of 2018, Tongshun. The water quality of 4 of the 5 assessment sections of the river has been improved to Class IV. The goal is to reach Class III water bodies by 2022.
Conclusion:
This article only briefly analyzes individual cases. There are also Yitong River, Huangshui River, Nakao River, Futian River, Funan River, Qinhuai River, etc., which are constantly emerging as benchmarks for river management and serve as benchmarks for other rivers. The management of rivers and lakes in the region provides a wealth of reference significance.
