Who has information on the safety and remediation of the Wenruitang River?

The scope of the comprehensive improvement of the Wenruitang River is the entire water system, with a total length of 1,305 kilometers and 39 towns and villages along the river

17 streets, wide range, heavy tasks, and great difficulty. This project is based on unified planning, full-line linkage, and hierarchical responsibility

The principle of sectional contracting, combination of management and management, and gradual improvement is carried out, and sewage interception, dredging, obstacle removal, widening, barging, and greening are implemented.

In order to reproduce the beautiful face of the "Mother River".

1. Target positioning.

1. The remediation of Wenruitang River takes water control as the center, water pollution prevention and control and water quality improvement as the foundation, and makes Wenruitang River truly become Wenzhou's "urban pond river, ecological pond river, cultural pond river, landscape pond river" through comprehensive remediation measures such as obstacle removal, dredging, sewage interception, pollution control, bank revetment, greening, landscape construction, etc., so as to provide support and guarantee for Wenzhou's comprehensive construction of a well-off society.

II. Basic Principles.

1. The principle of pollution control. The most serious problem of the water environment is pollution, and we must put the solution of the pollution problem in the first place, and through the general survey of pollution sources, we must find out the contribution rate of various pollution sources to river water pollution, so as to prescribe the right medicine and intercept the pollution sources.

2. The principle of ecological water control. It is necessary to attach importance to the study of the water ecological environment, use advanced ecological means to harness rivers, and strive to reduce the pollution load. We should protect the existing waters with a good ecological environment, especially the rural rivers and the key protected waters of the three wetlands.

3. The principle of the combination of mountains and rivers. Water control must inevitably control mountains to prevent damage to the river water environment due to soil erosion. It is necessary to strengthen soil and water conservation, afforestation, beautification of mountains and rivers, prevention and control of soil erosion in the mountains around the river, and strengthen the control of man-made soil erosion.

4. The principle of highlighting the landscape. Construct green channels and a number of water environment landscape projects along the river, protect cultural relics and historic sites, and truly build the river into a beautiful landscape, so as to achieve the improvement of the living environment, the improvement of environmental quality, and the improvement of urban quality.

5. The principle of lasting water control. The formation of modern river water environment is directly related to the economic and social development of the whole region, the construction of urban infrastructure, and the improvement of people's awareness of civilization.

6. The principle of simultaneous construction and management. In the comprehensive improvement of the Wenruitang River, it is necessary to prevent the tendency of emphasizing construction and neglecting management. At present, the city's economic strength is not strong enough, and the appearance of the river is difficult to change with engineering measures, strengthening management should become an important means to reduce the pressure on the river water environment.

3. Technical requirements.

1. Water conservancy. It is required to meet the flood control and drainage standards stipulated in the Wenzhou urban flood control plan, and the width of the river channel, the elevation of the bottom of the riverbed, and the height of the river bank meet the requirements of the plan.

2. Environmental protection. In the near term (2002), the black and odorous phenomenon of the main river channel will be basically eliminated, and in the long term (2010), according to the requirements of the overall plan, the water quality of the river will meet the standards stipulated in the water function zoning.

3. Greening. It is required to combine the construction of green belt with bank protection projects, and the width of the green belt on both sides of the main river channel shall be controlled by 30 meters in principle, at least not less than 15 meters, and the two sides of the main tributaries shall not be less than 8 meters in principle.

4. Shipping. To meet the requirements of inland waterway shipping planning, the main river of Zhedan should meet the first rise of level 7 shipping, and the main tributaries should meet the requirements of level 8 shipping.

5. Urban landscape along the river. The façade and height of buildings along the river should be strictly controlled, and the building control area should be demarcated when the towns are building on the bank of the Tang River.

The Regulations on the Protection and Management of Wenruitang River in Zhejiang Province are formulated in accordance with the Law of the People's Republic of China on the Prevention and Control of Water Pollution and other relevant laws and administrative regulations, combined with the actual situation of Wenzhou, in order to improve the ecological environment and living environment of Wenruitang River, protect the history and culture of Wenruitang River, and promote the harmonious coexistence of man and nature.
