Water is the source of life and an important resource for urban development. However, with the acceleration of urbanization, the shortage of water resources and pollution problems are becoming increasingly prominent. The rapid urban development is bringing great challenges to the ecological environment and sustainable development of cities. How to make the sewage "regeneration" then to solve the urban water shortage, has become an urgent problem to be solved.
In recent years, all over the world actively change the concept of water use, increase the scale of recycled water use and expand the use of recycled water. By reducing the amount of fresh water intake and sewage out of the city to promote water conservation, pollution control, emission reduction and promote each other. According to the preliminary statistics of the Ministry of Housing and Urban-Rural Development, in 2022, the national urban recycled water use will reach 18 billion cubic meters, which is 4.6 times higher than 10 years ago.
Reclaimed water is water that has been treated to meet certain quality standards and usage requirements. Reclaimed water utilization refers to the use of reclaimed water for agricultural irrigation, industrial recycling cooling, urban greening, public buildings, road cleaning, ecological water replenishment and other fields. Recycled water utilization can not only save fresh water resources and reduce water extraction costs, but also reduce the amount of sewage discharge, improve the quality of the water environment and enhance the ability of cities to withstand natural disasters such as drought.
In addition, industrial enterprises are encouraged to use recycled water instead of tap water for industrial production to promote the recycling of industrial water and enhance the quality and efficiency of enterprises. For example, Gaomi City in Shandong Province has more than 300 industrial enterprises above the scale, with a large amount of industrial water consumption. As a city with relatively scarce water resources, Gaomi City has adhered to the concept of green development in recent years and encouraged industrial enterprises to use recycled water instead of tap water for industrial production, and through the construction of a number of water recycling projects, the city's industrial enterprises have achieved a water reuse rate of more than 80%.
Reclaimed water use is an effective way of wastewater treatment, which is important to solve the problem of urban water shortage and promote the green development of the city. We should further strengthen the publicity and promotion of recycled water use to form a social atmosphere of water conservation, water conservation and water love.
