Ningbo was selected as the nationwide recycled water use configuration pilot to take you to understand Ningbo's "regenerative water"

Recently, Ningbo has successfully selected the list of pilot cities in the first batch of recycled water in the country in the country. According to the implementation plan of the pilot cities, Ningbo will invest about 16.1 billion yuan to implement a number of strategic and driving recycled water -related projects. Among them, the investment was completed by about 13.6 billion yuan during the pilot period. By 2025, the recycled water utilization rate of the city reached 35%, and the recycled water utilization was 700,000 tons/day.

What does this series of numbers mean for the city of Ningbo?

What is "regenerative water"?

Let's talk about the concept of "regeneration water".

The relevant person in charge of the Ningbo Water Affairs and Environment Group introduced to reporters that if the recycled water is placed with our daily drinking water, it is basically impossible to distinguish with the naked eye. After dozens of processes processing, it finally meets a certain water quality requirements, meets certain use functions, and can safely use water. It has the advantages of stable water volume, controllable water quality, and available on -site available.

The reason why Ningbo needs to use recycled water efficiently is related to the current status of water resources. Due to the uneven distribution of water resources in our city, Ningbo is actually a season with seasonal water shortage.

At this stage, Ningbo's per capita water resources occupy 885 cubic meters, only 60%of the province's per capita level. A new round of water resources comprehensive plan shows that by 2025, the city's water resources gap will reach 300 million cubic meters, and the gap in 2035 will reach 550 million cubic meters. The current status of water resources will be difficult to support high -quality economic and social development in the future.

Since it is short of water, it is necessary to open source. As a result, Ningbo turned his attention to hundreds of millions of cubic meters of sewage generated each year.

Data show that in 2021, the scale of sewage treatment in Ningbo City was 590 million cubic meters, of which regenerated water was only 87 million cubic meters. Therefore, at the beginning of the article, Ningbo City strived to reach 35%of the recycled water utilization rate in 2025, with a total of 250 million cubic meters, an increase of 187%from 2021.

Why is it?

The common fields of recycled water are mainly river ecological hydration, industrial water supply and municipal mixed use. Combined with national policies and Ningbo industrial characteristics, it is not difficult to see that if we can revitalize this part of water resources, the significance will be strategically -

In the context of achieving the "double carbon" of carbon peaks and carbon neutralization, my country has implemented strict water consumption dual -control system.

Ningbo, as a strategic pilot cities for manufacturing a strong country, has a high degree of dependence on water resources in the industrial industry. In 2021, the city's production water volume was 1.589 billion cubic meters, of which 673 million cubic meters of water used in the second industry, accounting for 42.4%. At the end of the "Fourteenth Five -Year Plan", the GDP is expected to increase by 500 billion yuan in GDP, which is inseparable from the corresponding water factor support behind it.

As a unconventional water source, regenerative water can effectively improve the use of water resources and optimize the overall allocation structure of water resources, help build conventional water sources and unconventional water sources for complemention and appointment. New models of water supply to promote carbon reduction and efficiency, and inject vitality to create a regional green circular economy.

What are the benefits?

In addition to injecting new vitality into economic development, the relevant person in charge of the Municipal Water Environment Group also introduced that the use of recycled water will become a new carrier for optimizing the water environment governance model.

At present, the traditional ecological hydration model in Ningbo is generally adopted in the form of reservoir hydration, Yaojiang water supplementation, and overseas water diversion. The supply and demand gap is large, and the improvement of river network liquidity is limited.

When regeneration water is used as ecological hydration, its water source is stable and has a bit of a wide range of extensive and regenerative replacement. It can be planned, adjustable, and continuously supplemented to the landscape water bodies such as river nets, supplemented by ecological means such as corresponding water quality activation, river cultivation and other ecological means to improve the quality of water environment and achieve natural repair of urban water ecology.

Green water and green mountains are Jinshan Yinshan. It is also worth mentioning that the economic benefits of regenerative water for ecological hydration are also considerable. After regenerating water supplement to the river network, it can be used as an industrial water plant to take water, and the water source can be used again to achieve circulating efficiency. Based on the city's ecological environment water volume of 0.59 billion cubic meters in 2021, if you choose to replace the regenerative water, this conventional water source is used for industrial production, calculated at 11.3 cubic meters of industrial added value of 10,000 yuan, and the active industrial output value will be activated to further release the water out of the water out of the water out. Resources on the double effect of economic development.

The relevant person in charge of the municipal water conservancy and water competent department frankly said: "Overall, if the recycled water is included in the water resources strategic guarantee system, it will significantly make up for the shortcomings of the city's water resources and effectively build a strong urban tough water safety guarantee system."
