Only the right medicine can be found to find the "total switch" of water treatment

A few days ago, the 2022 China Water Motorcycle League was held in Shahu, Ningxia. Saga's Helan Mountains, shining golden beaches, clear and blue sand lakes, landscapes, lakes and sand, camel bells, waves to fly boat ... This beautiful picture of beautiful pictures allows more than 200 athletes and vast number The tourists were extremely shocking, and the clean sand lake water also impressed the athletes.

In the 1980s, the unique natural scenery of "half of Sands and Half of Lakes, one side of Jiangnan" was successfully entered into the "National 5A Tourist Scenic Area" and "China's Top Ten Charm Wetlands", and its economic benefits were obvious. However, the development model of "re -development and light protection" is destined to be unsustainable. For a period of time, the water quality of Shahu has deteriorated, and it once reached a bad category. Its famous dish "Sand Lake Big Fish Head" is even labeled by tourists. As a typical sealing lake in the northwest, the precipitation is less than 200 mm, but the evaporation is more than 10 times, and the sand lake ecology is even more innate. Relevant parties have invested hundreds of millions of yuan in funds to govern sand lakes, but they have little effect. In 2016, the water quality problem of Shahu was named by the Eighth Ecological Environmental Protection Supervision Team. The party committee and government of the Ningxia Hui Autonomous Region attached great importance to it. The two party committee secretaries were personally served as the chief of the lake and arrested the governance.

At one time, more ways to "dilute" the "diluted" of the Yellow River water, the water quality governance was in the dead cycle of "adding more water, water with more water", and it also caused great waste of distress to the precious Yellow River water. Practice has proved that only by scientific water treatment and finding a source of pollution, the right medicine can be found to find the "total switch" of water treatment and take out the comprehensive governance "golden key". Shahu finally concluded that the governance ideas of "external isolation, internal circulation, water replacement, sewage relocation, ecological repair, and comprehensive governance" are the result of scientific decision -making.

In the end, Shahu did not hesitate to stop the garden closed at the closed door, washing the mud and sand, and truly realized completely rectification. Anti -seepage isolation grooves and dredging drainage ditch are formed. Internal circulation projects ensure lake water circulation. 6000 acres of oxidation ponds and tertiary oxidation projects make the lake water purify and then enter the lake. Waiting for a series of combined fists, finally made Shahu look refreshing. The average year of the water quality of Shahu was category IV in 2018, reaching Class III after 2020, and birds increased from more than 100 species to more than 210 species. The governance of Shahu has become an "excellent case of beautiful rivers and lakes", and governance experience communicates in the country.

It turns out that the river and lake ecosystem is a complex comprehensive system, which is the result of the interaction, migration, and transformation of its watershed water bodies, sediments, aquatic plants, and various substances. Water quality problems are often manifested in the lake. The root is on the shore. It must be determined and then moved. Comprehensive remediation is carried out with the concept of systematic governance. It can achieve the expected results by relying on science.

General Secretary Xi Jinping gave Ningxia's mission to Ningxia's mission to "strive to build the Yellow River Basin's ecological protection and high -quality development pioneer zone" during the inspection of Ningxia. The Thirteenth Party Congress of Ningxia held in June this year included the "ecological priority" in the five major strategies of the autonomous region, emphasizing the basic task of taking care of the health of the Yellow River, and implementing the strictest ecological environmental protection system, co -promoting carbon reduction, festivals, festivals, festivals Water, pollution reduction, greening, and growth, comprehensively improving the stability of the resource ecosystem and ecological service functions.

The governance of Shahu is far more than one lake. Water is expensive as oil in the northwest, and water -saving water and water is a major event. How to ensure the safety of water in the middle and upper reaches of the Yellow River? How to ensure the ecological safety of the Yellow River Basin and even northern China? How to make the people from the region of the evaporation area see the green mountains and green mountains and realize the livelihood? Under the guidance of Xi Jinping's thought of ecological civilization, it is the only choice to take the basis of science and the effectiveness of comprehensive governance.

The current water quality governance of Shahu has achieved quite good results, but it is impossible to do it once and for all. Only with the full consideration of land, shore, and water body, the water source, water quality, and water ecology are comprehensively coordinated, and the comprehensive management of grass and sand, systemic governance, and source governance of landscapes, forests, lakes, and lakes, forests, and lakes can make governance sustainable.
