Comprehensive management of the whole basin, all-round and whole system to control the outflow of water into the Yellow River.

CCTV News:Fenhe River is the second largest tributary of the Yellow River, with a total length of more than 700 kilometers and a drainage area of nearly 40,000 square kilometers, which nourishes a quarter of Shanxi’s land. Since 2017, in accordance with the general requirements of "making the Fenhe River rich in water, improving water quality and beautiful scenery", Shanxi has launched a new chapter in the whole basin, all-round and whole-system management of the Fenhe River to ensure that "a clear water enters the Yellow River".

The front desk reporter Zhang Xiangdi:I am now at the intersection of the Fenhe River and the Yellow River in Yuncheng, Shanxi. After 713 kilometers of flowing in Shanxi, the Fenhe River flows into the Yellow River from here. What is the water quality of Fenhe River flowing into the Yellow River? Not far away, there is the last national ecological monitoring station where Fenhe River flows into the Yellow River. Let’s take a look.

What I have in my hand is the water that has just been taken out from the Fenhe River into the Yellow River, so how to test the index of this water? There is an instrument here, which automatically samples and tests the water next to Fenhe River every four hours, and judges whether the water quality of Fenhe River reaches the standard through the analysis of various data.

Wu Xiaokui, Deputy Director of Wanrong Branch of Yuncheng Ecological Environment Bureau:From 2021 to now, the water quality (entering the Yellow Estuary) can basically be stabilized at Class IV, and it can reach Class III or even close to Class II in good times.

The front desk reporter Zhang Xiangdi:How did the Fenhe River change from the inferior grade V water quality before 2017 to above grade IV water quality now? Let’s take a look at the source first.

The front desk reporter Zhang Xiangdi:This is the source of Fenhe River in Ningwu, Shanxi Province. The water at the source of Fenhe River comes from Guancen Mountain behind me. Fourteen sources of living water, large and small, flow down from the mountain and gather here, all the way south.

At present, the source of Fenhe River has beautiful scenery, but it was once severely damaged by extensive mining and excessive logging. "Flooding in rainy season, no running water in dry season, and sewage in peacetime" is the description of the source of Fenhe River by local villagers.

Li Jianming, Director of ningwu county Fenhe Governance Affairs Center:Before the treatment, the whole source can be said to be in ruins, with broken bricks and tiles everywhere. Through our years of governance, 511 polluting enterprises have been eradicated and shut down, and 2.46 million tons of waste materials and garbage have been cleared. The mountains are mainly afforestation and conservation forests, and the forest coverage rate has increased to 45.3% now.

Nowadays, the water flowing from the source of Fenhe River has been stable at Grade II water quality all the year round. The water quality at the source is guaranteed, and how to deal with the discharge of domestic sewage from towns along the Fenhe River is also the key to improve the water quality of Fenhe River. Since 2020, Shanxi has strengthened the construction and transformation of infrastructure such as sewage treatment along the Fenhe River, and gradually realized the full coverage of centralized domestic sewage treatment capacity in cities along the line.

The front desk reporter Zhang Xiangdi:This is a sewage treatment plant in Taiyuan. Every day, a large amount of domestic sewage is treated here and discharged directly into Fenhe River. This bottle of water is the appearance of domestic sewage entering the factory. After pretreatment, biological treatment and advanced treatment, such a clear bottle of water is obtained. Only when this standard is reached can the Fenhe River be discharged directly.

Now, Taiyuan has realized the full collection and treatment of domestic sewage, and the full collection and treatment project of domestic sewage along the Fenhe River is also progressing steadily.

In recent years, along the Fenhe River, a perfect ecological wetland system has been formed through measures such as wetland and ecological protection forest construction, and the self-purification ability of the river has been improved. Today, the Fenhe River is a blue sky, and the water quality continues to improve. The comprehensive management in all directions, regions and the whole process has truly realized "one clear water enters the Yellow River".
