The significance of sewage treatment for us?

With the development of urban water shortage pressure is growing, the root cause of the urban water crisis, people increasingly realize that it is the social cycle of water beyond the scope of the natural cycle of water can be carried. Therefore, only by fully respecting the law of natural water movement, rational use of water resources, so that the water cycle in the upstream area does not affect the function of the water body in the downstream waters, the social cycle does not harm the objective law of natural cycle, so as to maintain or restore the city and even the basin of the good water environment, is an effective way to the sustainable use of water resources. This requires us to change from the one-way open water use pattern of "water intake - water transmission - users - discharge" to "water intake - water transmission - users - recycled water" in a controlled manner. -Users - Recycled water" to improve the efficiency of water utilization. To realize this major change in the water use pattern, strengthening the recycling of sewage is the key. With the progress of science and technology, urban sewage is no longer wastewater, but a valuable resource. Since it is a resource, it should be utilized to the maximum extent. Improving the recycling rate of urban wastewater can reduce pollutant emissions and save limited water resources. Cheng Xiaobing, deputy director of the Water Resources Department of the Ministry of Water Resources, spoke at the "2010 Urban Water Strategy Forum" organized by Tsinghua University and China Water Network, pointing out that China's water resources are in short supply, and the urban water shortage problem is prominent, sewage reuse is a strategic choice, which is of great significance. Urban wastewater treatment and reuse in the alternative clean water while reducing the amount of sewage discharge, reducing the urban sewage load, with a stable amount of water, water transmission distance is short, low cost of water production and other characteristics, can provide a safe and reliable alternative source of water, is to solve the problem of water shortage in the city's strategic choice. Promote the reuse of sewage treatment fully embodies the scientific concept of development and people-oriented requirements, reflecting the urgent desire of the masses, is to promote the objective needs of urbanization, is to achieve a rational allocation of water resources, scientific protection, recycling of important means of resource-saving, environmentally friendly society is of great significance to the construction of China's economic development and rapid development is of great significance.
