Promote the utilization of sewage resources to solve the three major water problems of water shortage, water environmental pollution and water ecological damage

For example, in the implementation of key sewage resource utilization projects, led by the Ministry of Housing and the National Development and Reform Commission, the Ministry of Ecology and Environment to participate in the implementation of sewage collection and resource utilization facilities construction projects; Led by the Ministry of Ecology and Environment, the National Development and Reform Commission, the Ministry of Housing and Urban-Rural Development, and the Ministry of Water Resources participated in the implementation of regional recycled water recycling projects, and formulated pilot implementation plans for regional recycled water recycling.

China Economic Herald reporter learned at this on-site meeting that at present, the relevant departments have actively acted to improve the political position and mission awareness, refine the deployment and compacting responsibilities, and lay a good foundation for the utilization of sewage resources.

The utilization of sewage resources needs to be actively promoted by all localities

The work of sewage resource utilization not only requires comprehensive management departments and industry departments to establish a linkage mechanism with each performing its own duties, each taking its own responsibilities, cooperating with each other and working together, but also requires the active implementation of various localities.

The natural endowment of water resources in Beijing is insufficient, and the serious shortage of water resources is the basic situation of the city. Lai Xianxu, director of the Beijing Municipal Commission of Development and Reform, said, "In order to deal with the contradiction of water shortage, Beijing in addition to strengthening production and life water conservation, strengthen the use of external water transfer and other measures, put forward the 'sewage resource strategy', actively promote the utilization of sewage resources, and recycled water has become a stable second water source in Beijing."

"Beijing always regards sewage treatment and resource utilization as an important area of national economic and social development." Lai Xiyu introduced: "Especially in the '14th Five-Year Plan' outline of the emphasis on promoting the efficient use of water resources recycling, requiring the strengthening of the multiple, echelon and safe use of recycled water, improve the capacity of recycled water transmission and distribution."

At the same time, Beijing has innovated investment and financing models to strengthen the utilization of sewage resources. According to Lai Xianyu, "The central urban area is franchised, Beijing Urban Drainage Group is responsible for the investment, construction and operation of recycled water facilities in the central urban area, and the government arranges investment subsidies in accordance with the franchise agreement." In the suburbs, the model of 'enterprise construction and government distribution network' is adopted to realize the comprehensive market-oriented construction and operation of recycled water plants."

It is worth mentioning that in order to enrich the application scenarios of recycled water, Beijing encourages recycled water to serve the high-end manufacturing industry in the capital. "In the central city of Beijing, 100 percent of industrial water has been replaced by recycled water." "Especially in Yizhuang Economic Development Zone, where advanced industries are concentrated, SMIC and other high-tech enterprises have extremely high requirements for water quality and water source stability. In order to save water resources and meet the needs of relevant industrial enterprises, the recycled water is further purified into high-quality recycled water whose water quality is higher than tap water through in-depth treatment, so as to realize the full use of recycled water by high-tech enterprises."

In addition, Beijing has taken a series of effective measures to actively promote the utilization of sewage resources, such as promoting the reform of "discharge and management service" and accelerating the construction of projects for the mutual benefit of sewage resources; Adhere to ecological water control and encourage the return of reclaimed water to nature; Make full use of the price lever and build a price system to encourage the application of recycled water.

The amount of water per capita in Ningbo, Zhejiang province, is only half the national average. In this regard, Bao Zhengcao, deputy director of the Ningbo Municipal Development and Reform Commission, said, "Ningbo takes planning as the guide, takes the market as the guide, 'the government sets the stage, the enterprise sings the opera', strengthens the policy support, continues to promote the upgrading of sewage treatment facilities and high-level construction, accelerates the utilization of sewage resources, and vigorously promotes the green innovation and development of sewage treatment enterprises. A number of benchmark companies and landmark projects have emerged."
