With the rapid development of social economy and the acceleration of urbanization, the problem of environmental pollution has become increasingly prominent, among which water pollution has become one of the important factors restricting the sustainable development of China's economy and society. In this context, the overall transformation of environmental protection has become an inevitable trend, and sewage treatment technology, as an important part of environmental protection, has also ushered in unprecedented development opportunities and challenges.

I. Background analysis

In recent years, the state attaches great importance to the protection of ecological environment, and has successively promulgated a series of policies and regulations to promote the construction of a green and low-carbon recycling development system, and strengthened the requirements for various pollutant discharge standards. Especially in the management and utilization of water resources, the goal of realizing zero discharge of industrial wastewater and full collection and treatment of urban domestic sewage is put forward, and advanced and applicable technical means are encouraged to improve the treatment efficiency and quality.

Second, driven by technological innovation

Facing the new situation and new requirements, China's sewage treatment industry actively embraces scientific and technological innovation and constantly explores and practices new models and technologies. On the one hand, through the introduction and absorption of foreign mature experience and technological achievements, combined with the actual situation of the local digestion and transformation; On the other hand, it is independent research and development of core equipment and technological processes with independent intellectual property rights. For example, membrane bioreactor (MBR), advanced oxidation and other new generation treatment methods with high efficiency and low energy consumption have gradually become the mainstream choice.

Third, the improvement of intelligent management

In addition to the progress of hardware facilities, efforts are also needed at the software level to ensure the stable and reliable operation of the system. With the help of Internet of Things, big data, cloud computing and other information technologies, an intelligent operation management platform can be built, which can monitor the water quality changes in real time, automatically adjust control parameters, effectively prevent failures and reduce operating costs. In addition, we should establish and improve the environmental information disclosure system, strengthen public participation and social supervision, and form a good situation of government guidance, enterprise main body and multi-party cooperation.

Fourth, summarize the prospects

To sum up, "Overall Upgrading of Sewage Treatment under the Overall Transformation of Environmental Protection" is not only related to the major issue of improving the quality of human living environment, but also a key indicator to test the level of green development in a country or region. In the next few years, the support of relevant policies will increase and the market demand will continue to grow. We have reason to believe that China will achieve more brilliant achievements in this field and contribute more "China Plan" and "China Wisdom" to the global ecological civilization construction. At the same time, it will also promote the vigorous development of upstream and downstream enterprises in related industrial chains and create more economic benefits and social values.
