In this regard, the first batch of pilot cities in the country, Zhejiang 6!

Recently, with the consent of the provincial government and reported to the six national ministries and commissions, the record of six cities, counties (cities, districts) of Ningbo, Changxing County, Pinghu City, Shaoxing City, Yiwu City, and Yuhuan City were identified as the first batch of countries. Typical areas of recycled water are used for pilot cities. Each pilot cities will fully carry out the use of recycled water use, and strive to reach more than 25%by 2025.

Regenerative water refers to the water purification treatment of the production of domestic sewage. Finally, it meets a certain water quality requirements to meet a certain use function, and it can be used safely. It has the advantages of stable water volume, controllable water quality, and available on -site available. The common fields of recycled water are mainly river ecological hydration, industrial water supply and municipal mixed use.

In recent years, Zhejiang has fully promoted the use of unconventional water, and rationally deployed a number of recycled water to use infrastructure to expand the construction of recycled water treatment capacity. The province's urban regeneration water conservancy rate reached an average of 20.5%.

Ningbo City

As a representative of modern coastal cities, Ningbo City adapted to local conditions to explore the recycled water use model in the fields of river ecological hydration, industrial water sources, finished industrial water, etc. to build 32 centralized urban domestic sewage treatment plants with a daily processing capacity of about 2.627 million tons. Among them, recycled water water The daily production capacity is 717,900 tons.

After being included in the pilot, Ningbo will invest about 16.1 billion yuan to implement a number of strategic and driving recycled water -related projects. By 2025, the city's recycled water utilization rate will reach 35%, and the total volume will reach 250 million cubic meters, which is an increase from 2021 to increase. 129%.

Changxing County

In 2021, the utilization rate of recycled water in Changxing County reached 28%, of which the annual utilization of the recycled water industrialization was about 22 million cubic meters, accounting for more than one -third of the province's total, and the total amount and utilization indicator led the province. Among them, the daily reincarnation of the water saving and emission reduction project of Zheleng Changxing Power Generation Co., Ltd. is 50,000 tons, which refreshed the scale of the use of recycled water in the south of the Yangtze River.

By carrying out the construction of renewable water use, Changxing County will comprehensively innovate the configuration method, expand the area of ​​allocation, improve the facilities and losses facilities, and establish and improve relevant incentive policies to form a set of iconic results. By 2025, the use of recycled water conservancy in the county will reach 35%, which can correspond to 4340 tons of chemical oxygen demand emissions, reduce ammonia nitrogen emissions by 450 tons, and further show water saving and environmental benefits.

Pinghu City

In 2021, the total water consumption of Pinghu City was 2346.1 billion cubic meters, which had reached 90%of the pre -allocated water volume during the "14th Five -Year Plan" period of Jiaxing City. The use of recycled water has become the only way to crack the lack of water indicators in Pinghu City and the shortage of high -quality water resources.

After being included in the pilot, Pinghu City will invest about 568 million yuan. Through the implementation of the "1124" regenerative water use layout, that is, "1 centralized water supply park, 1 point -to -point water supply model, 2 agricultural recycled water innovation, 4 major water use fields, 4 major water use fields "Full coverage", the water supply rate of industrial recycled water will reach 45,000 cubic meters per day by 2025, and the recycled water conservancy rate will be more than 28%.

Keqiao District, Shaoxing City

As the county -level administrative region with the largest industrial water in the province, the industrial water used in Keqiao District, Shaoxing City has accounted for more than 50%of the total water consumption in the region. On the one hand, the high water -consuming textile industry that accounts for more than half of the output value of the regional regulations. On the other hand, the economic and social development has put forward higher requirements for the guarantee of regional water resources. Promoting the use of regenerative water to optimize the water supply structure in Keqiao District, alleviate the contradiction between supply and demand, and the contradiction between supply and demand. Key grabbing.

The goal of creating "centralized treatment, centralized supply, key breakthroughs, and exploration" in Shaoxing Keqiao District aimed at creating a "high -water industrial agglomeration area". The amount of water consumption and 10,000 yuan of industrial value -added water consumption is reduced by 18.0%and 22.0%compared with 2020, and the utilization rate of recycled water reaches more than 28%, of which the utilization of industrial recycled water is more than 45 million cubic meters.

Yiwu City

Yiwu has a dense population and developed industrial and commercial, but a quarter of the average level of per capita water resources has caused great inconvenience to the production and life of residents.

In order to accurately break the problem, Yiwu City has vigorously carried out the quality of water supply since 2014. Through the setting of double -water pipes and dual water meters, high -quality water sources are used for drinking water for life, and septum water is used for industrial enterprises production, toilet, and municipal roads. Greening is used, so as to replace more high -quality water resources to ensure residents' lives and create new models of recycled water.

In 2022, Yiwu City plans to complete 20 million tons of water supply. By 2025, the regeneration of regeneration water in Yiwu will reach 50 million tons/year. By 2030, the high -quality water resources replaced by Yiwu will reach more than 100 million tons each year.

Yuhuan City

As a typical island Peninsula City, Yuhuan City is lacking in freshwater resources. The per capita surface water resources are only 432m³, only 1/4 of the province, far lower than the province (1744M³) and the national (2100m³) average level. It is the province. One of the most water -deficient areas.

During the pilot period, Yuhuan City will focus on building the island peninsula area recycled water to use the national benchmark target positioning to optimize the planning layout and strengthening the management of regenerative water configuration. After the efforts, we strive to achieve the use of recycled water in 2025 to more than 50%in 2025. Compared with the status quo's recycled water conservancy rate, the level of recycling water is at a leading level in the province and China. In the next step, the six typical areas will focus on creating a modern Binhai metropolis national recycled water use benchmarking, Binhu water environment sensitive area regeneration water use of the configuration model, Binhai Plain river net water environment sensitive area recycled water conservancy model, high water consumption industry agglomeration area recycling water Use the configuration model and cross -region multi -water sources to coordinate recycled water to use the configuration model and the island peninsula area to use the target positioning of the nation's benchmark to provide reference for the province to improve the level of recycled recycled utilization, and to promote the use of sewage resources throughout the country.
